Authorizing Cannabis for Medical Purposes
The legalization of cannabis for recreational purposes came into effect with the Cannabis Act in October 2018, and patients continue to have access to cannabis for therapeutic purposes. The Cannabis Regulations have replaced the Access to Cannabis for Medical Purposes Regulations. Patients can obtain cannabis for medical purposes when a physician or nurse practitioner provides a “medical document” , authorizing its use, and determining the daily dried cannabis dose in grams.
With the authorization, patients have the choice whether to (a) buy directly from a federally licensed producer; (b) register with Health Canada to produce a limited amount for personal consumption; (c) designate someone to produce it for them; or (d) buy cannabis at provincial or territorial authorized retail outlets or online sales platforms, if above the legal age limit.
While acknowledging the unique requirements of patients suffering from a terminal illness or chronic disease for which conventional therapies have not been effective and for whom cannabis may provide relief, physicians remain concerned about the serious lack of clinical research, guidance and regulatory oversight for cannabis as a medical treatment. There is insufficient clinical information on safety and efficacy for most therapeutic claims. There is little information around therapeutic and toxic dosages and knowledge on interactions with medications. Besides the need for appropriate research, health practitioners would benefit from unbiased, accredited educational modules and decision support tools based on the best available evidence.
The Canadian Medical Association has consistently expressed concern with the role of gatekeeper that physicians have been asked to take as a result of court decisions. Physicians should not feel obligated to authorize cannabis for medical purposes.
Physicians who choose to authorize cannabis for their patients must comply with their provincial or territorial regulatory College's relevant guideline or policy. They should also be familiar with regulations and guidance, particularly:
Health Canada’s Information for Health Care Practitioners – Medical Use of Cannabis (monograph, summary and daily dose fact sheet),
the Canadian Medical Protective Association’s guidance;
the College of Family Physicians of Canada’s preliminary guidance Authorizing Dried Cannabis for Chronic Pain or Anxiety; and
the Simplified guideline for prescribing medical cannabinoids in primary care, published in the Canadian Family Physician.
The CMA recommends that physicians should:
Ensure that there is no conflict of interest, such as direct or indirect economic interest in a licensed cannabis producer or be involved in dispensing cannabis;
Treat the authorization as an insured service, similar to a prescription, and not charge patients or the licensed producer for this service;
Until such time as there is compelling evidence of its efficacy and safety for specific indications, consider authorizing cannabis only after conventional therapies are proven ineffective in treating patients’ conditions;
Have the necessary clinical knowledge to authorize cannabis for medical purposes;
Only authorize in the context of an established patient-physician relationship;
Assess the patient’s medical history, conduct a physical examination and assess for the risk of addiction and diversion, using available clinical support tools and tests;
Engage in a consent discussion with patients which includes information about the known benefits and adverse health effects of cannabis in its various forms (e.g., edibles), including the risk of impairment to activities such as driving and work;
Advise the patient regarding harm reduction strategies and the prevention of accidental exposure for children and other people;
Document all consent discussions in patients' medical records;
Reassess the patient on a regular basis for its effectiveness to address the medical condition for which cannabis was authorized, as well as for addiction and diversion, to support maintenance, adjustment or discontinuation of treatment; and
Record the authorization of cannabis for medical purposes similar to when prescribing a controlled medication.
The Cannabis Regulations provide some consistency with many established provincial and territorial prescription monitoring programs for controlled substances. Licensed producers of cannabis for medical purposes are required to provide information to provincial and territorial medical licensing bodies upon request, including healthcare practitioner information, daily quantity of dried cannabis supported, period of use, date of document and basic patient information. The Minister of Health can also report physicians to their College should there be reasonable grounds that there has been a contravention of the Narcotic Control Regulations or the Cannabis Regulations.

The Built Environment is part of the overall ecosystem of our earth. It encompasses all the buildings, spaces and products that are created, or at least significantly modified by people. It includes our homes, schools and workplaces, parks, business areas and roads. It extends overhead in the form of electric transmission lines, underground in the form of waste disposal sites and subway trains and across the country in the form of highways (Health Canada, 1997)."
The built environment affects every one of us every day, and mounting evidence suggests that it can play a significant role in our state of health and well-being. This policy statement provides the perspective of the Canadian Medical Association on how the built environment can influence health, and what all sectors in society might do to ensure that community design and development takes the health of residents into consideration.
In the 19th century, the industrial revolution attracted hordes of people into cities. Congestion, squalid living conditions, and lack of clean water, clean air, and proper sewage systems led to outbreaks of diseases such as cholera and tuberculosis. These events, coupled with the development of the germ theory, served as a catalyst for public and professional awareness of how the built environment has direct health impacts; clean water, fresh air, uncongested living conditions, and proper housing were all recognized as constituents of good health.
During the past three decades, the 'Healthy Cities' movement has brought a renewed interest to the health implications of the built environment by focusing on disease prevention through community design. Over the years this idea has proliferated, and a body of literature has grown revealing the large scope of health risk factors that may be influenced by the built environment. The literature indicates that the following connections between the built environment and public health are possible:
o Decreased physical activity
o Increased prevalence of obesity
o Increased prevalence of asthma and other respiratory diseases
o Injuries and unintended fatalities
o Heat exposure. (Frank , Kavage S, & Devlin A, 2012) (Franks, Kavage & Devlin, 2012; Health Canada 2013)
There is also mounting evidence that these factors may be compounded for vulnerable populations such as children, the elderly, and those living in poverty.
Smart Growth is an urban planning and transportation theory that became popular almost two decades ago. Though different organizations may differ slightly in their view of what smart growth means, its general aims are to build compact accessible cities that avoid urban sprawl and mitigate auto-dependence. The 'Smart Growth' movement contains tenets that research supports in creating healthy built environments such as mixed land uses, providing transportation alternatives like walking and bicycle infrastructure and public transit, and creating walkable neighbourhoods. (Smart Growth BC, 2012)(See definitions)
What the Research Is Telling Us
Canada's physical activity guidelines recommend that children from 5 to 11 should be active for at least 60 minutes a day; those 18 and over should be active for at least 150 minutes per week. (Canadian Society of Exercise Physiology, 2011). Participation in regular physical activity bestows substantial health benefits; it can lengthen and improve quality of life and reduce the risk for many physical and mental health conditions. Physical activity can improve overall fitness, lower risk for heart disease, stroke, and high blood pressure, lower risk for non-insulin dependent diabetes and the risk of overweight. (Dannenberg, Frumkin, & Jackson, 2011) Physical activity includes more than exercise and leisure time activity, it also includes active transportation such as walking to school, work or errands as part of daily living.
One of the most important determinants of physical activity is a person's neighbourhood. (Jackson & Kochtotzky) Research shows that urban sprawl, access to parks and recreation/fitness facilities, and neighbourhood walkability all may have an impact on physical activity levels (Cutts, Darby, Boone, & Brewis, 2009; Ewing, Schmid, Killingsworth, Zlot, & Raudenbush, 2003).
Individuals living in walkable neighbourhood with a mix of land uses and interconnected street networks were found to be 2-4 times more likely to achieve 30 minutes moderate physical activity a day. Urban design characteristics associated with higher physical activity rates include pedestrian-oriented street and site design, parks, trails, playgrounds and other recreational facilities within walking distance and sidewalks. (Frank , Kavage S, & Devlin A, 2012)
A barrier to physical activity can be the perception of the lack of a safe place to be active. Safety concerns keep 1 in 5 Canadians from walking or bicycling. Urban design that encourages walking and cycling can improve perceived neighbourhood safety. (Heart and Stroke Foundation of Canada, 2011)
There are unique barriers to active modes of transportation in rural communities. Rural environments often lack pedestrian facilities and bike lanes; stores, schools, jobs, and services are sometimes located far apart from homes; and parks and recreation facilities are rare. Understanding these barriers is the first step towards finding opportunities to remove them. (Active Living Research and the Public Health Institute, 2013)
CMA' policy on Active Transportation recommends that all sectors (government, business and the public) work together, as a matter of priority, to create a culture in their communities that supports and encourages active transportation and physical activity.
Increased prevalence of obesity
Obesity has almost doubled in the past 3 decades; in 1978 the measured obesity rate was 13.8% and in 2008 the measured obesity rate was 25.4% (PHAC/CIHI, 2011). Obesity is associated with high blood pressure, stroke, and heart disease, which are among the leading causes of disability and death (Statistics Canada, 2008). Mental health conditions, type II diabetes, several types of cancer, among many other diseases, are also linked to obesity (Guh, Zhang, Bansback, Amarsi, Birmingham, & Anis, 2009). The combined cost of obesity and these related conditions was estimated to be $4.3 billion dollars in 2005 (Public Health Agency of Canada, 2012).
There are many factors involved in this increase, but a causal indicator is the decline in physical activity among Canadians: In 2005, 47% of Canadians were reported as being 'inactive' (Human Resource and Skills Development Canada, 2006).
Urban design that encourages sedentary living habits such as work, home, school and shopping separated by distances that discourage walking, parking lots built as close as possible to final destinations not only discourage walking but encourage automobile usage. (Jackson, Kochtitzky, CDC) Less walkable, auto dependent built environments have been correlated with higher body weights and obesity. (Frank , Kavage S, & Devlin A, 2012)
Furthermore, research indicates that the food environment that we live in, and the amount of healthy food choices we have access to, can affect the chance of becoming obese as well. For example, neighbourhoods with a high density of fast food restaurants or neighbourhoods with poor access to grocery stores (food deserts) have both been correlated with obesity (Larsen & Gilliland, 2008; Cummins & Macintyre, 2006; Frank L. D., 2009).
Increased prevalence of asthma and other respiratory diseases
In August 2008, the CMA released a report estimating that the effects of air pollution would result in 11,000 hospital admissions and 21,000 deaths Canada wide, totaling a financial cost of close to $8.1 billion dollar (Canadian Medical Association, 2008). Carbon monoxide, sulfur and nitrogen oxides, volatile organic compounds, ozone, and lead, among other toxins, are emitted into the air every day from industrial processes and car exhaust. These air-borne chemicals are associated with heart disease, cancer, acute respiratory illness, and the aggravation of other respiratory illnesses such as asthma (Frank L. D., 2009). While the built environment does not directly produce these chemicals, it has a role to play in where those chemicals are emitted, where they are concentrated, and, in the case of vehicles, how much of them are produced.
Urban sprawl has been tied to longer commute times and higher total vehicle miles traveled per person. Neighbourhood design and walkability have been identified as factors that can affect number of vehicle trips taken and transportation mode choice, and increased mixed land use has been identified as a factor that could further decrease emission rates (Newman & Kenworthy, 1989; Frank, Sallis, Conway, Chapman, Saelens, & Bachman, 2006).
Injuries and unintentional fatalities
Transport-related injuries accounted for a total of $3.7 billion dollars in healthcare costs in Canada in 2009 (SmartRisk, 2009). The majority of this financial burden was related to motor vehicle, pedestrian, and cycling accidents. Death and injuries from these types of incidents typically happen at a younger age which both
increases the years of life lost due to death or disability and the financial burden of continuing care (SmartRisk, 2009).
The built environment perhaps has the most identifiable and direct correlation to this category of impacts. Designs of auto-oriented environments that promote high traffic volume, high traffic speed, and low accessibility for pedestrians and cyclists lead to increased incidence of injuries and fatalities (Surface Transportation Policy Partnership, 2002).
Increased prevalence of illness and death related to heat exposure
The 'urban heat island effect' is a phenomenon correlated with urban environments that are primarily asphalt and concrete and lack vegetation and green space. Such environments have been estimated to have anywhere from 1oC to 12oC higher surface level temperatures in comparison to rural areas (United States Environmental Protection Agency, 2012). This can be especially dangerous for elderly individuals in the summertime and studies have demonstrated increased mortality amongst these populations during hot summers (Centers for Disease Control and Prevention, 2009). This is not only an issue of building materials and the balance of green space but has to do with isolation as well: If elderly residents have poor access to public transportation they may not be able to reach air-conditioned facilities.
Noise - be it from transport, industry, neighbours, or construction - is a prominent feature of the urban environment. Prolonged exposure to environmental noise has been directly linked to physical and psychosocial health outcomes, including hypertension, high blood pressure and heart disease, hearing impairment, stress levels, and sleep. There is some evidence linking noise to reduced ability to concentrate and more aggressive behavior. (Stansfeld SA, 2003)
In general, denser neighbourhoods have higher levels of ambient noise through the concentration of more people, traffic, and activities. However, as with air pollution, noise exposure is extremely site-specific and not necessarily exclusive to walkable or auto-oriented neighbourhoods. (Frank , Kavage S, & Devlin A, 2012) Canadian noise mapping data would assist researchers in assessing how environmental noise affects health and assist communities to proactively manage noise pollution.
The research shows that certain built environment characteristics may affect specific populations such as children, the elderly, low-income populations.
Children: Overweight and obesity is an issue for Canadians nationwide, but particularly so for children. Between 1978 to 2004 there was a 70% increase in overweight and obese children aged 12-17 (Statistics Canada, 2006). Obesity in children can lead to health issues such as hypertension, glucose intolerance, and orthopedic complications (Statistics Canada, 2006). Furthermore obesity in childhood has a high likelihood of carrying over into adulthood and may result in further health problems such as diabetes and heart disease (Statistics Canada, 2006). With this in mind, environments that promote physical activity are especially important for this segment of the population. Living in mixed use communities with walkable destinations, parks and recreational facilities is related to greater physical activity. (Dannenburg, Frumkin & Jackson, 2011)
Elderly: The elderly population is generally less physically robust and more prone to chronic illnesses, which make them especially vulnerable to air pollution and heat exposure. Physical activity is an important aspect of daily life for this age group as it has been shown to reduce the negative health impacts of aging (Vogel, Brechat, Lepetre, Kaltenbach, Berthel, & Lonsdorfer, 2009). Being physically active however, requires accessible and safe streets that cater to the needs of individuals with mobility issues. Special consideration is required when constructing the built environment to ensure the needs of this growing population.
CMA's policy on Health and Health Care Principles for an Aging Population recommends that communities take the needs and potential limitations of older Canadians into account when designing buildings, walkways, transportation systems or other aspects of the built environment.
Low Income Populations: Low income populations are at higher risk for chronic illnesses such as high blood pressure and diabetes, and have a lower overall survivability for major heart attacks (Centre for Chronic Disease Prevention and Control. , 2002; Statistics Canada, 1996-97). They are also more likely to smoke, be overweight or obese, and are less likely to be physically active (Creatore, Gozdyra, Booth, & Glazier, 2007). Many of these factors may be due to limited access to stable housing, housing location (normally close to highways or industrial zones with high pollution exposure), neighbourhood safety, and lack of access to or affordability of healthy food options.
Planning and public health combined efforts in the 19th century to improve living conditions. Today there is a need for health care practitioners, particularly those in the public health field, and community planners to work together, to share their expertise and efforts, to improve the health and well-being of Canadians. By designing communities that encourage and support healthy living - physical activity, healthy weights, access to healthy foods - we can address some of the risk factors for many chronic diseases and create supportive, active communities.
Health Care Associations can:
o Advocate for health supportive environments by increasing the public and policy makers' understanding of the impact of the built environment on health.
o Advocate for the contribution that public health professionals can make to urban planning and development to ensure that population health impacts are recognized and mitigated.
o Provide community planners with strong public health arguments and health data to support healthy communities.
Health Care Professionals can:
o Incorporate an awareness of a patient's built environment (such as housing, access to transportation and healthy foods) into treatment programs and health counseling.
o Encourage your community to adopt policies and design principles that build healthy supportive environments.
Federal, Provincial and Local Governments can:
o Integrate concepts of population health into urban planning.
o Promote multidisciplinary planning teams, including professionals in medicine, public health and community design to ensure that all stakeholders take health impacts into account.
o Incorporate health impact assessments into community planning and development initiatives in the public sector.
o Encourage the private sector to provide infrastructure and amenities in developments that promote healthy living.
The Public can:
o Learn more about the connection between the built environment and health and advocate for positive change.
o Become involved in public consultations regarding local community planning and development.
o Develop research projects at the Federal level on the impact of the built environment on health to inform and help coordinate programs and initiatives at the provincial and local levels.
o Focus on creating a standardized set of health indicators that can be uniformly applied to assess the status of a community's built environment.
o Research into the effectiveness of policy options on various communities (urban, suburban, rural).
It is important that we acknowledge how our surroundings can affect our lives and health, and work together to create positive change. The CMA is willing to work with other people and organizations to ensure that the influence of the built environment on health receives the attention that it warrants with the ultimate goal of building or re-inventing healthy communities for all Canadians.
In order of appearance
Inactive: "Respondents are classified as active, moderately active or inactive based on an index of average daily physical activity over the past 3 months. For each leisure time physical activity engaged in by the respondent, an average daily energy expenditure is calculated by multiplying the number of times the activity was performed by the average duration of the activity by the energy cost (kilocalories per kilogram of body weight per hour) of the activity. The index is calculated as the sum of the average daily energy expenditures of all activities. Respondents are classified as follows: 3.0 kcal/kg/day or more = physically active; 1.5 to 2.9 kcal/kg/day = moderately active; less than 1.5 kcal/kg/day = inactive". (Human Resource and Skills Development Canada, 2006).
Urban Sprawl: "A particular type of suburban development characterized by very low-density settlements, both residential and non-residential; dominance of movement by use of private automobiles, unlimited outward expansion of new subdivisions and leap-frog developments of these subdivisions; and segregation of land uses by activity." (United States Department of Housing and Urban Development, 1999)
Walkability: Walkability refers to the ease with which pedestrians can move within and between environments. The literature gives varied definitions but the main variable to consider are the following: mixed land use (defined below), proximity to destinations (accessibility and convenience), pedestrian facilities (sidewalks, urban furniture etc...), street connectivity (short block lengths, availability of multiple alternate routes etc...), aesthetics (landscape, vegetation, architecture), presences of public spaces (parks, plazas, etc...), presence of traffic calming measures (lower speed limits, street narrowing, speed bumps etc...), and access to transit. (Shay, Spoon, & Khattak, 2003)
Transportation Mode Choice: Transportation mode choice refers to an individuals decision regarding how to get from one destination to another. The theory behind mode choice is complex and involves characteristics of the built environment, socio-demographic and socioeconomic variables, benefit-cost analysis, and personal preference. (Cervero, Built Environments and Mode Choice: Toward a Normative Framework, 2002)
Mixed Land Use: "Land use mix is the composition of uses within a given geographic area." (Cervero, Land Use Mixing and Suburban Mobility, 1998) The uses referred to can be restaurants, offices, studios, shops, or any variety of business, institution, natural space, or recreation site. In the literature there are various indices and equations used to measure the degree of 'mixed land use' in an area.
Urban Heat Island Effect: The urban heat island effect occurs when the sun significantly heats urban surfaces (concrete, asphalt, etc...) to significantly higher temperatures than the surroundings air (can be upwards of 27-50oC). Comparatively shaded or more moist regions (such as rural areas with lots of vegetation) stay much closer to the surrounding air temperature. This heat imbalance between urban surfaces and surrounding air causes heat to transfer from those surfaces to the air, elevated the temperature above what it normally would be. This happens both at a surface and an atmospheric level. (United States Environmental Protection Agency, 2012)
Smart Growth: Smart Growth is an urban planning and transportation theory that became popular almost two decades ago. Though different organization's may differ slightly in their view of what smart growth means, it's general aims are to build compact accessible cities that avoid urban sprawl and mitigate auto-dependence. Some of the principles of this movement are as follows:
1). Incorporate mixed land uses into community designs
2). Build compact, accessible neighbourhoods close to jobs and amenities
3). Provide alternative modes of public transportation
4). Diversify housing to meet the needs of people from all socioeconomic classes
5). Maintain and protect natural open spaces
6). Build within existing communities instead of developing beyond community boundaries
7). Preserve agricultural land
8). Use new, sustainable technology in infrastructure and buildings
9). Develop community identity
10). Encourage active citizens to remain engaged in their communities

COMPLEMENTARY AND ALTERNATIVE MEDICINE
This statement discusses the Canadian Medical Association's (CMA) position on complementary and alternative medicine (CAM). CAM, widely used in Canada, is increasingly being subject to regulation. The CMA's position is based on the fundamental premise that decisions about health care interventions used in Canada should be based on sound scientific evidence as to their safety, efficacy and effectiveness - the same standard by which physicians and all other elements of the health care system should be assessed. Patients deserve the highest standard of treatment available, and physicians, other health practitioners, manufacturers, regulators and researchers should all work toward this end. All elements of the health care system should "consider first the well-being of the patient."1 The ethical principle of non-maleficence obliges physicians to reduce their patient's risks of harm. Physicians must constantly strive to balance the potential benefits of an intervention against its potential side effects, harms or burdens. To help physicians meet this obligation, patients should inform their physician if the patient uses CAM.
CAM in Canada
CAM has been defined as "a group of diverse medical and health care systems, practices and products that are not presently considered to be part of conventional medicine."i This definition comprises a great many different, otherwise unrelated products, therapies and devices, with varying origins and levels of supporting scientific evidence. For the purpose of this analysis, the CMA divides CAM into four general categories:
* Diagnostic Tests: Provided by CAM practitioners. Unknown are the toxicity levels or the source of test material, e.g., purity. Clinical sensitivity, specificity, and predictive value should be evidence-based.
* Products: Herbal and other remedies are widely available over-the-counter at pharmacies and health food stores. In Canada these are regulated at the federal level under the term Natural Health Products.
* Interventions: Treatments such as spinal manipulation and electromagnetic field therapy may be offered by a variety of providers, regulated or otherwise.
* Practitioners: There are a large variety of practitioners whose fields include chiropractic, naturopathy, traditional Chinese and Ayurvedic medicine, and many others. Many are unregulated or regulated only in some provinces/territories of Canada.
Many Canadians have used, or are currently using, at least one CAM modality. A variety of reasons has been cited for CAM use, including: tradition; curiosity; distrust of mainstream medicine; and belief in the "holistic" concept of health which CAM practitioners and users believe they provide. For most Canadians the use is complementary (in addition to conventional medicine) rather than alternative (as a replacement). Many patients do not tell their physicians that they are using CAM.
Toward Evidence-Informed Health Care
Use of CAM carries risks, of which its users may be unaware. Indiscriminate use and undiscriminating acceptance of CAM could lead to misinformation, false expectations, and diversion from more appropriate care, as well as adverse health effects, some of them serious.
The CMA recommends that federal, provincial and territorial governments respond to the health care needs of Canadians by ensuring the provision of clinical care that continually incorporates evidence-informed technological advances in information, prevention, and diagnostic and therapeutic services.2 Physicians take seriously their duty to advocate for quality health care and help their patients choose the most beneficial interventions. Physicians strongly support the right of patients to make informed decisions about their medical care. However, the CMA's Code of Ethics requires physicians to recommend only those diagnostic and therapeutic procedures that they consider to be beneficial to the patient or to others.3 Until CAM interventions are supported by scientifically-valid evidence, physicians should not recommend them. Unless proven beneficial, CAM services should not be publicly funded. To help ensure that Canadians receive the highest-quality health care, the CMA recommends that CAM be subject to rigorous research on its effects, that it be strictly regulated, and that health professionals and the public have access to reliable, accurate, evidence-informed information on CAM products and therapies. Specific recommendations are provided below:
a) Research: Building an Evidence Base
To date, much of the public's information on CAM has been anecdotal, or founded on exaggerated claims of benefit based on few or low-quality studies. The CMA is committed to the principle that, before any new treatment is adopted and applied by the medical profession, it must first be rigorously tested and recognized as evidence-informed.4 Increasingly, good-quality, well-controlled studies are being conducted on CAM products and therapies. The CMA supports this development. Research into promising therapies is always welcome and should be encouraged, provided that it is subject to the same standards for proof and efficacy as those for conventional medical and pharmaceutical treatments. The knowledge thus obtained should be widely disseminated to health professionals and the public.
b) An Appropriate Regulatory Framework
Regulatory frameworks governing CAM, like those governing any health intervention, should enshrine the concept that therapies should have a proven benefit before being represented to Canadians as effective health treatments.
i) Natural Health Products. Natural health products are regulated at the federal level through the Natural Health Products Directorate of Health Canada.
The CMA believes that the principle of fairness must be applied to the regulatory process so that natural health products are treated fairly in comparison with other health products.5 The same regulatory standards should apply to both natural health products and pharmaceutical health products. These standards should be applied to natural health products regardless of whether a health claim is made for the product. This framework must facilitate the entry of products onto the market that are known to be safe and effective, and impede the entry of products that are not known to be safe and effective until they are better understood. It should also ensure high manufacturing standards to assure consumers of the products' safety, quality and purity. The CMA also recommends that a series of standards be developed for each natural health product. These standards should include:
* manufacturing processes that ensure the purity, safety and quality of the product;
* labelling standards that include standards for consumer advice, cautions and claims, and explanations for the safe use of the product to the consumer.6
The CMA recommends that safety and efficacy claims for natural health products be evaluated by an arm's length scientific panel, and claims for the therapeutic value of natural health products should be prohibited when the supportive evidence does not meet the evidentiary standard required of medications regulated by Health Canada.7 Claims of medical benefit should only be permitted when compelling scientific evidence of their safety and efficacy exists.8
The Canadian Medical Association advocates that foods fortified with "natural health" ingredients should be regulated as food products and not as natural health products
The CMA recommends that the regulatory system for natural health products be applied to post-marketing surveillance as well as pre-marketing regulatory review. Health Canada's MedEffect adverse reaction reporting system now collects safety reports on Natural Health Products. Consumers, health professionals and manufacturers are encouraged to report adverse reactions to Health Canada.
ii) CAM Practitioners. Regulation of CAM practitioners is at different stages. The CMA believes that this regulation should: ensure that the services CAM practitioners offer are truly efficacious; establish quality control mechanisms and appropriate standards of practice; and work to develop an evidence-informed body of competence that develops with evolving knowledge.
Just as the CMA believes that natural health products should be treated fairly in comparison with other health products, it recommends that CAM practitioners be held to the same standards as other health professionals. All CAM practitioners should develop Codes of Ethics that insure practitioners consider first the best interests of their patients.
Among other things, associations representing CAM practitioners should develop and adhere to conflict of interest guidelines that require their members to:
* Resist any influence or interference that could undermine their professional integrity;9
* Recognize and disclose conflicts of interest that arise in the course of their professional duties and activities, and resolve them in the best interests of patients;10
* Refrain, for the most part, from dispensing the products they prescribe. Engaging in both prescribing and dispensing , whether for financial benefit or not, constitutes a conflict of interest where the provider's own interests conflict with their duty to act in the best interests of the patient.
c) Information and Promotion
Canadians have the right to reliable, accurate information on CAM products and therapies to help ensure that the treatment choices they make are informed. The CMA recommends that governments, manufacturers, health care providers and other stakeholders work together to ensure that Canadians have access to this information. The CMA believes that all natural health products should be labeled so as to include a qualitative list of all ingredients. 11 Information on CAM should be user-friendly and easy to access, and should include:
* Instructions for use;
* Indications that the product or therapy has been convincingly proven to treat;
* Contraindications, side effects and interactions with other medications;
* Should advise the consumer to inform their health care provider during any encounter that they are using this product.12
This information should be provided in such a way as to minimize the impact of vested commercial interests on its content.
In general, brand-specific advertising is a less than optimal way of providing information about any health product or therapy. In view of our limited knowledge of their effectiveness and the risks they may contain risks, the advertising of health claims for natural health products should be severely restricted. The CMA recommends that health claims be promoted only if they have been established with sound scientific evidence. This restriction should apply not only to advertising, but also to all statements made in product or company Web sites and communications to distributors and the public. Advertisements should be pre-cleared to ensure that they contain no deceptive messages. Sanctions against deceptive advertising must be rigidly enforced, with Health Canada devoting adequate resources to monitor and correct misleading claims.
The CMA recommends that product labels include approved health claims, cautions and contraindications, instructions for the safe use of the product, and a recommendation that patients tell physicians that they are using the products. If no health claims are approved for a particular natural health product, the label should include a prominent notice that there is no evidence the product contributes to health or alleviates disease.
The Role of Health Professionals
Whether or not physicians and other health professionals support the use of CAM, it is important that they have access to reliable information on CAM products and therapies, so that they can discuss them with their patients.
Patients should be encouraged to report use of all health products, including natural health products, to health care providers during consultations. The CMA encourages Canadians to become educated about their own health and health care, and to appraise all health information critically.
The CMA will continue to advocate for evidence-informed assessment of all methods of health care in Canada, and for the provision of accurate, timely and reliable health information to Canadian health care providers and patients.

Ensuring equitable access to effective and appropriate health care services is one strategy which can help to mitigate health inequities resulting from differences in the social and economic conditions of Canadians.
Equitable access can be defined as the opportunity of patients to obtain appropriate health care services based on their perceived need for care. This necessitates consideration of not only availability of services but quality of care as well.1
There is far ranging evidence indicating that access to care is not equitable in Canada. Those with higher socio-economic status have increased access for almost every health service available, despite having a generally higher health status and therefore a decreased need for health care. This includes insured services (such as surgery), as well as un-insured services such as pharmaceuticals and long-term care.
Those from disadvantaged groups are less likely to receive appropriate health care even if access to the system is available. They are more likely to report trouble getting appointments, less testing and monitoring of chronic health conditions, and more hospitalizations for conditions that could be avoided with appropriate primary care.
There is a financial cost to this disparity in equitable care. Reducing the differences in avoidable hospitalizations alone could save the system millions of dollars.
Barriers to equitable access occur on both the patient and health care system or supply side. Common barriers include:
(see pdf for correct display of table)
Demand Side or Patient Barriers
Supply Side or System Barriers
Services not located in areas of need
Cultural beliefs and norms
Patients lack family physicians
Lack of management of chronic disease
Cost of transportation
Long waits for service
Time off work for appointments
Payment models which don't account for complexity of patients
Access to child care
Coordination between primary care and speciality care and between health care and community services
Payment for medications or other medical devices/treatments
Standardization of referral and access to specialists and social services
Immobility- due to physical disabilities, and/or mental health barriers
Lack of needs based planning to ensure that population has necessary services
Cognitive issues, ie. Dementia, that adversely affect ability to access and comply with care
Attitudes of health care workers
To tackle barriers on the patient side there is a need to reduce barriers such as transportation and the prohibitive cost of some medically necessary services. Further, there is a need to increase the health literacy of patients and their families/caregivers as well as providing support to health care providers to ensure that all patients are able to be active participants in the management of their care.
On the system side the strategies for action fall into four main categories: patient-centred primary care which focuses on chronic disease management; better care coordination and access to necessary medical services along the continuum of care; quality improvement initiatives which incorporate considerations of equity as part of their mandate; and health system planning and assessment which prioritizes equitable access to care.
Recommendations are provided for CMA and national level initiatives; health care planners; and physicians in practice.
Despite a commitment to equal access to health care for all Canadians there are differences in access and quality of care for many groups. By removing barriers on both the patient and system side it is hoped that greater access to appropriate care will follow.
In Canada as in many countries around the world there are major inequities in health status across the population. Those lower on the socio-economic scale face higher burdens of disease, greater disability and even shorter life expectancies.2 Many of these disparities are caused by differences in social and economic factors such as income and education known as the social determinants of health.3,1 While many of these factors are outside of the direct control of the health care system, ensuring equitable access to effective and appropriate health care services can help to mitigate some of these disparities. The alternative can also be true. In health systems where access to care and appropriateness are unequal and skewed in favour of those of higher socio-economic status, the health system itself can create further inequities and add greater burden to those already at an increased risk of poor health. Physicians as leaders in the health care system can play a role in ensuring equitable access to care for all Canadians.
Equitable Access to Health Care in Canada:
Equitable access can be defined as the opportunity for patients to obtain appropriate health care services based on their perceived need for care. This necessitates consideration of not only availability of services but quality of care as well.4
Due to burden of disease and therefore need, those with lower socio-economic status should be utilizing more services along the continuum.5 That, however, is not the case. Individuals living in lower income neighbourhoods, younger adults and men are less likely to have primary care physicians than their counterparts.6
Primary care physicians deliver the majority of mental illness treatment and they are the main source of referrals to psychiatrists or other specialists. However, much of the care for people with mental illnesses, especially on the lower socio-economic end of the scale, is delivered in emergency rooms, which is both costly and episodic. This is due not only to a lack of primary care access but to a lack of community mental health services.7
Those with higher socio-economic status are much more likely to have access to and utilize specialist services.8 Examples include greater likelihood of catheterization and shorter waits for angiography for patients with myocardial infarction9; and greater access to in-hospital physiotherapy, occupational therapy, and speech language therapy for those hospitalized with acute stroke10. Low income men and women with diabetes were just as likely to visit a specialist for treatment as high income individuals despite a significantly greater need for care.11
There is a correlation between higher income and access to day surgery.12 A Toronto study found that inpatient surgery patients were of much higher income than medical inpatients.13 Additionally, utilization of diagnostic imaging services is greater among those in higher socio-economic groups.14 Access to preventive and screening programs such as pap smears and mammography are lower among disadvantaged groups.15
Geography can cause barriers to access. In general rural Canadians have higher health care needs but less access to care.16 People in northern and rural communities typically have to travel great distances to obtain health services as many, especially specialist services, cannot be obtained in their home community.17 Those living in the most rural communities in Canada are the least likely to have a regular family doctor, or to have had a specialist physician visit.18 According to data from the Society of Rural Physicians of Canada, 21% of the Canadian population is rural while only 9.4% of family physicians and 3% of specialists are considered rural.19 This lack of access to specialists and other medically necessary services can lead to delays in treatment and harm to health including unnecessary pain and permanent disability.20 Further, travel for necessary treatment often comes with a significant financial cost.21
It is not just access to insured services that is a problem in Canada. Many Canadians do not have access to needed pharmaceuticals. Researchers have reported that those in the lowest income groups are three times less likely to fill prescriptions, and 60% less able to get needed tests because of cost.22 The use of appropriate diabetes preventative services, medication, and blood glucose testing, has been shown to be dependent on out of pocket expenditures.23
Rehabilitation services are difficult for some Canadians to access as well. Services such as physiotherapy and occupational therapy are often not covered unless they are provided in-hospital or to people on certain disability support programs. This leads to long wait times for services that are covered or no access at all.24 Adding to these inequities is the fact that different programs are covered in different provinces and territories.25
Access to mental health services is a major challenge for Canadians. According to data from Statistics Canada, more than half a million Canadians who had a perceived need for mental health care services, reported that their needs were unmet. Access to counselling services was the most frequent unmet need reported.26 A number of important mental health professionals - notably psychologists and counsellors - are not funded through provincial health budgets, or are funded only on a very limited basis. Access to psychologists is largely limited to people who can pay for them, through private insurance or out of their own pockets.27,2
Access to subsidized residential care, long-term care, home care and end-of-life care is problematic as well. Those with means can access high quality long-term care services within their community, while those with inadequate resources are placed in lower quality facilities sometimes hours away from family and friends.28 Even with expansions promised by governments, home care will not be able to meet the needs of underserved groups such as those living in rural and remote areas.29 Finally, only a fraction of patients have access to or receive palliative and end-of-life care. Those living in rural or remote areas or living with disabilities have severely limited access to formal palliative care.30
Difficulties in access are particularly acute for Canada's Aboriginal peoples. Many live in communities with limited access to health care services, sometimes having to travel hundreds of miles to access care.31 Additionally, there are jurisdictional challenges; many fall through the cracks between the provincial and federal health systems. While geography is a significant barrier for Aboriginal peoples, it is not the only one. Aboriginals living in Canada's urban centres also face difficulties. Poverty, social exclusion and discrimination can be barriers to needed health care. Of all federal spending on Aboriginal programs and services only 10% is allocated to urban Aboriginals. This means that Aboriginals living in urban areas are unable to access programs such as Aboriginal head start, or alcohol and drug services, which would be available if they were living on reserve.32 Further, even when care is available it may not be culturally appropriate. Finally, Canada's Aboriginal peoples tend to be over-represented in populations most at risk and with the greatest need for care, making the lack of access a much greater issue for their health status.33
However, these examples are only part of the story as accessing care which is inappropriate cannot be considered equitable access.34 Those of lower socio-economic status are more likely to use inpatient services; show an increased use of family physician services once initial contact is made;35 and have consistently higher hospitalization rates; 36 This could be due to the higher burden of need or could demonstrate that the services that are received are not addressing the health care needs of those lower on the socio-economic scale.37
Women and men from low-income neighbourhoods are more likely to report difficulties making appointments with their family doctors for urgent non-emergent health problems. They were also more likely to report unmet health care needs.38 In terms of hospitalizations, people with lower socio-economic status were much more likely to be hospitalized for ambulatory care sensitive conditions (ACSC) and mental health39; admissions which could potentially be avoided with appropriate primary care.40 They were also found to have on average longer lengths of stay.41 According to a study of hospitals in the Toronto Central Local Health Integration Network, patients considered to be Alternate Level of Care were more likely to have a low-income profile.42
Further, people with ACSC in low-income groups, those living in rural areas, or those with multiple chronic conditions were twice as likely to report the use of emergency department services for care that could have been provided by a primary care provider.43
There is a financial cost to this disparity. According to a 2011 report, low-income residents in Saskatoon alone consume an additional $179 million in health care costs than middle income earners.44 A 2010 study by CIHI found increased costs for avoidable hospitalizations for ambulatory care sensitive conditions were $89 million for males and $71 million for females with an additional $248 million in extra costs related to excess hospitalizations for mental health reasons.45
Areas for Action:
As the background suggests, equitable access is about more than just utilization of services. There are patient characteristics as well as complex factors within the health system which determine whether equitable access is achieved. Recent work has categorized access as having considerations on the supply of services and demand of patients for care. On the demand or patient side we must consider: ability to perceive; ability to seek, ability to reach, ability to pay, and ability to engage. On the supply side or health system considerations include: approachability; acceptability, availability and accommodation, affordability, and appropriateness. 46 The following table highlights some of the current barriers to equitable access.
(See PDF for correct display of table)

Supply Side or System Barriers
Services not located in areas of need
Cultural beliefs and norms

Lack of management of chronic disease
Cost of transportation

Immobility- due to physical disabilities, and/or mental health barriers
Lack of needs based planning to ensure that population has necessary services
Cognitive issues, ie. Dementia, that adversely affect ability to access and comply with care
Attitudes of health care workers
Patient based actions for improving equitable access:
Low health literacy can lead to difficulties for some Canadians in perceiving a need for care.47 Evidence suggests that more than half of Canadian adults (60%), lack the capacity to obtain, understand and act upon health information and services in order to make health decisions on their own.48 Many physicians are undertaking strategies to minimize this lack of health literacy among their patients. Examples include plain language resources as well as teach-back exercises which allow physicians to determine whether patients have fully understood the information provided.49 These efforts should continue to be supported.
Understanding how the health system works and where to access services can be a problem for some individuals.50 Beliefs about the need and value for certain services can also undermine the ability of patients in seeking care.51 Work needs to be done to ensure that disadvantaged groups are aware of the services that are available to them and the benefits of taking preventative steps in their health.
Low-income Canadians are ten times more likely to report unmet needs of health care due to the cost of transportation.52 Other barriers include a lack of child care, and ability to get time off work to attend necessary health appointments.53 Strategies that provide patients with transportation to appointments or subsidies for such travel have seen some success. Extended office hours and evening appointments can increase access for those unable to take time off work. Additionally, programs that provide patients with home visits from health care providers can help to eliminate this barrier. Further support and expansion of these programs should be explored.
There is also the inability to pay for services not covered by provincial plans such as pharmaceuticals, physiotherapy and other rehabilitation services.54 According to a 2005 report on diabetes in Canada, affordability and access to medical supplies was the biggest challenge for those Canadians living with diabetes.55 Access to services such as mental health counselling, subsidized residential care, and long-term care are also hindered by the inability to pay.
Even if patients are able to obtain care they may not be able to fully engage. Language difficulties, low health literacy, cognitive challenges (ie. Dementia), cultural mores and norms, and discrimination or insensitivity of health care workers, may all act as barriers to full participation in care.56 Efforts should be made to develop teaching methods to improve engagement of patients and their families/caregivers from disadvantaged groups.57 Strategies to remove or minimize the barriers created by a lack of health literacy should be developed and shared with physicians and other health care providers. Further, programs which facilitate access to services including interpretation and translation of key health information should be supported.58
Finally, an understanding of a patient's cultural and social context is important. The Royal College of Physicians and Surgeons of Canada and the Association of Faculties of Medicine of Canada have developed training modules for physicians who will be working with Canada's Aboriginal peoples.59 Similar programs have been developed by the Canadian Paediatric Society, and the Society of Obstetricians and Gynaecologists of Canada. More of this training is needed and should focus on groups who are likely to experience disadvantage in health care access and appropriateness.
Recommendations for action:
CMA and National Level Initiatives
The CMA recommends that:
1. Governments develop a national strategy for improving the health literacy of Canadians which takes into account the special needs of different cultures.
2. Governments provide accessible and affordable transportation options for patients requiring medical services when such services are unavailable locally.
3. Governments, in consultation with the life and health insurance industry and the public, establish a program of comprehensive prescription drug coverage to be administered through reimbursement of provincial/territorial and private prescription drug plans to ensure that all Canadians have access to medically necessary drug therapies.
4. Governments examine methods to ensure that low-income and other disadvantaged Canadians have greater access to needed medical interventions such as rehabilitation services, mental health, home care, and end-of-life care.
5. Governments explore options to provide funding for long-term care services for all Canadians.
6. Governments ensure that necessary interpretation and translation services are provided at all points of care.
Physicians in Practice
The CMA recommends that
7. Physicians be supported in addressing the health literacy of their patients and their families/caregivers.
8. Physician education programs continue to emphasize the important cultural and social contexts in which their patients live.
System based actions for improving equitable access:
On the system side there are two main areas that need to be addressed: making sure that people can access the services that they need (approachability, availability and accommodation, and affordability); and ensuring that once they have accessed the system that services are appropriate for their health needs (acceptability and appropriateness). Strategies for action include: patient-centred primary care which focuses on chronic disease management; better care coordination and greater access to necessary medical services along the continuum; quality improvement initiatives which incorporate equity as part of their mandate; and health system planning and assessment which prioritizes equitable access to care.
1. Patient-centred primary care which focuses on chronic disease management and which includes programs to increase access to those most at need.
Comprehensive primary care offers the biggest possibility for increasing equitable access and reducing health disparities. Data from a large population study in Ontario indicates that inequities in access to primary care and appropriate chronic disease management are much larger than inequities in the treatment of acute conditions.60
Currently many primary care services are located outside of the neighbourhoods with the greatest need for care. While some are accessible through public transportation, there is still a need for more convenient access for these communities. Community health centres (CHC) offer a good model for addressing this challenge through location in disadvantaged neighbourhoods and the provision of culturally appropriate care.61 Additionally, CHCs offer a number of different health, and sometimes social services, under one roof making access to many different types of care more convenient for patients.
More work needs to be done to to reduce barriers in access to Canadians living in rural and remote communities. Telemedicine is one strategy that has increased access for rural Canadians. The Ontario Telemedicine Network is one example of this innovative approach. Patients in rural communities can have access to specialists in urban centres through their local health providers. Examples include cardiac rehab follow-up, tele-homecare to support lifestyle changes, and psychiatric or mental health consultations.62
Programs which encourage recruitment and training of health professionals from rural and disadvantaged populations have been found to increase access as these individuals are more likely to return to their home communities to practice.63
Medical schools have been attempting to increase the diversity in their schools for a number of years. However, work still needs to be done. Data from the 2012 student component of the National Physician Survey shows that 278 of the 2000 students who responded to the survey (13.9%) come from families considered to be in the top 1% of earners in Canada. This is compared to only 46 (2.3%) of students whose family incomes place them in the bottom quintile of earners. 64
One of the suggested strategies for increasing diversity in medical schools is increasing the knowledge about the medical profession among rural and disadvantaged young people. An innovative program in Alberta called Mini Docs allows children between the ages of six and 12 to learn about being a doctor and how to stay healthy. The children get to wear medical scrubs for the day and use harmless medical tools such as stethoscopes and bandages. The day long program is run by medical students.65
Strategies to remove financial barriers to access, such as scholarships, should be expanded. Further, there is a need to modify the admissions process to recognize the differences in access to programs such as MCAT preps and overseas volunteer experiences based on the availability of financial resources as well as the necessity of employment for some students while in medical school. This necessary employment may limit the time available for volunteer and community service.66
Another strategy that can be effective in increasing access is programs that seek to link primary care providers with unattached and underserved patients. Programs such as Health Care Connect in Ontario and the GP and Me program in British Columbia actively seek to link sometimes hard to serve patients to appropriate primary care.
The College of Family Physicians of Canada has developed a blueprint for comprehensive primary care for Canadians. The concept, a 'patient's medical home' seeks to link Canadians with a comprehensive health care team led by a family physician. These medical homes will take many forms but will be designed to increase both access and the patient-centredness of care.67
Another barrier to access is timeliness of service. Many patients are forced to use walk in clinics or emergency departments as they cannot receive the required care from their primary care providers. Use of walk-in clinics or emergency departments for primary care may lead to lost opportunities for prevention and health promotion.68 Advanced access programs can help to improve equitable access to care by facilitating timely appointments for all patients.69 The AIM (Access improvement measures) program in Alberta uses a system designed by the Institute for Healthcare Improvement to redesign practice to focus on same day appointments and elimination of unnecessary delays.70
Primary care which prioritizes chronic disease management offers the greatest potential for increasing appropriateness of care and reducing system costs. Those most likely to have chronic diseases are also those who face the biggest barriers to equitable access.71 Currently many people with ACSC do not receive the appropriate tests to monitor their conditions, management of their medications, or supports to self-manage their disease.72 Some programs do exist to encourage more effective management of chronic disease. The Champlain Local Health Integration Network (LHIN) in Ontario has developed a cardiovascular disease prevention network to improve care through the use of evidence based practices and better integration between all areas of the health care continuum.73 Primary Care networks in Alberta have similar goals designed to connect multiple physicians, clinics and regions together to support the health needs of the population.74
Further work is necessary to expand these types of programs and to provide appropriate compensation models for complex patients. Payment models in some jurisdictions undermine access by failing to take morbidity and co-morbidity into consideration in designing rates such as equal capitation.75
Finally, there is a need to encourage greater self-management of disease. Practice support programs in British Columbia are providing training to support physicians in increasing patient self-management and health literacy.76 Additional programs of this nature are necessary in all jurisdictions.
2. Better care coordination and greater access to necessary medical services along the continuum of care.
Patient-centred care which integrates care across the continuum and which includes community services will be necessary to ensure not only greater access but greater acceptability of care.77 Innovative programs focused on increasing the coordination in terms of transition from hospital to home have shown some success in preventing readmissions particularly when vulnerable populations are targeted.78 Health Links in Ontario aims to reduce costs, based on the assumption that much of the utilization of high cost services, such as emergency department visits, could be prevented with better coordinated care. One of the pilot sites in Guelph aims to assign one person in primary care, likely a doctor or a nurse, to be the primary contact for patients deemed high need and to intervene on behalf of these patients to ensure better care coordination.79
Further work is needed to ensure greater coordination in speciality care. As the evidence demonstrates, access to specialist services are skewed in favour of high-income patients. To reduce this inequity it may be necessary to standardize the referral process and facilitate the coordination of care from the primary care providers' perspective.80 A new program in British Columbia is designed to reduce some of these barriers by providing funding and support to rapid access programs which allow family physicians to access specialist care through a designated hotline. If no specialist is available immediately there is a commitment that the call will be returned within two hours. Specialists available through this program include cardiology, endocrinology, nephrology, psychiatry, and internal medicine among others.81 Similar programs in other jurisdictions could help to increase coordination between primary and speciality care.
Care coordination is only part of the problem, however. There is also a need to increase the access to services that are medically necessary across the care continuum. These include a lifetime prevention schedule82, diagnostic testing, specialty services, and access to appropriate rehabilitation services, mental health, long-term care and end of life care.
3. Quality improvement initiatives which incorporate considerations of equity as part of their mandate.
Equity has become a key component of many quality improvement initiatives around the world. The Health Quality Council Ontario identified nine attributes of a high-performing health system: safe, effective, patient-centred, accessible, efficient, equitable, integrated, appropriately resourced, and focused on population health.83
The POWER study, a large study of Ontario residents found that where there were targeted programs for quality improvement fewer inequities were observed. In particular they referred to the actions of Cancer Care Ontario and the Ontario Stroke Network. Both of these groups had undergone large quality improvement initiatives to standardize care and increase coordination of services through evidence-based guidelines and ongoing performance measurement. Considerations of accessibility and equity were specifically included. As a result of these efforts, the POWER study found that acute cancer and stroke care in Ontario were quite equitable.84
Similar efforts are underway in other jurisdictions. The Towards Optimized Practice initiative in Alberta supports efforts in medical offices to increase the use of clinical practice guidelines for care as well as quality improvement initiatives.85 Encouraging more health services and programs to undertake such quality improvement initiatives could help to reduce the inequities in access for all Canadians.
4. Health system planning and assessment which prioritizes equitable access to care
Considerations of equity must be built specifically into all planning considerations. Too often services are designed without adequate consideration of the specific needs of disadvantaged groups. Planners need to do a better job of understanding their practice populations and tailoring programs to those most in need of care.86 This planning should be done in consultation with other sectors that play a role in influencing the health of their practice populations.
Further, assessments of the equity and use of services is also needed. Some services may be designed in a way that is more appropriate for some than others, resulting in higher utilization among some groups and a lack of access for others.87 Innovative work is taking place in the Saskatoon Health Region to try and understand these barriers. Health care services are undergoing specific health equity assessments to ensure that all services meet the needs of diverse populations. This includes looking at the full spectrum of services from preventative care and education programs to tertiary level care such as dialysis. In Ontario, the local health integration networks (LHIN) have now been tasked with developing equity plans for their services. Clear goals and performance measurements are part of this work.88
One of the tools available to support this work is a health equity impact assessment tool developed by the Ontario Ministry of Health and Long-Term Care. This tool is intended for use by organizations within the health system as well as those outside the system who will impact on the health of Ontarians. The main focus of the tool is to reduce inequities that result from barriers in access to quality health services. Additionally, it is designed to identify unintended health impacts, both positive and negative, before a program or policy is implemented.89 Further work is needed to ensure that equity is included in the deliverables and performance management of health care organizations and provider groups across the country.90
To support these planning programs appropriate data will need to be collected. This data needs to be comprehensive for all services and needs to include specific data points which will allow planners as well as providers to understand the composition of their populations as well as measure and report on considerations of equity.91
Recommendations for action:
CMA and National Level Initiatives
The CMA recommends that:
9. Governments continue efforts to ensure that all Canadians have access to a family physician.
10. Appropriate compensation and incentive programs be established in all jurisdictions to support better management of chronic disease for all Canadians.
11. Governments provide funding and support to programs which facilitate greater integration between primary and speciality care.
12. With support from government, national medical organizations develop programs to increase standardization of care and the use of appropriate clinical practice guidelines.
13. Appropriate data collection and performance measurement systems be put in place to monitor equitable distribution of health services and greater appropriateness of care.
Health System Planners
The CMA recommends that:
14. Needs based planning be mandated for all health regions and health system planning. Equity impact assessment should be part of this planning to ensure that services meet the needs of all Canadians.
15. Chronic disease management and other supportive strategies for vulnerable patients at risk of frequent readmission to the acute care system be prioritized in all health systems.
16. Quality improvement initiatives be mandated in all care programs. These programs should include a specific focus on standardization of care and continuous quality improvement and should include equity of access as part of their mandate.
Physicians in Practice
The CMA recommends that:
17. Physicians be supported in efforts to offer timely access in primary care settings.
18. Physicians be supported in continued efforts to include all patients in decisions about their care and management of their illnesses.
19. Physicians be supported in continued efforts to standardize care and utilize evidence based clinical practice guidelines with a particular emphasis on the management of chronic disease.
20. Physicians be encouraged and adequately supported to participate in community-based interventions that target the social determinants of health.
Despite a commitment to equal access to health care for all Canadians there are differences in access and quality of care for many groups. For those that are most vulnerable, this lack of access can serve to further exacerbate their already increased burden of illness and disease. The strategies discussed above offer some opportunities for the health sector and the medical profession to intervene and mitigate this inequity. By removing barriers on both the patient and system side it is hoped that greater access to appropriate care will follow. While these strategies offer some hope, these actions alone will not be sufficient to increase the overall health of the Canadian population. Action is still required to tackle the underlying social and economic factors which lead to the disparities in the health of Canadians.

GUIDING PRINCIPLES FOR PHYSICIANS RECOMMENDING MOBILE HEALTH APPLICATIONS TO PATIENTS
This document is designed to provide basic information for physicians about how to assess a mobile health application for recommendation to a patient in the management of that patient's health, health care, and health care information.
These guiding principles build on the Canadian Medical Association's (CMA) Physician Guidelines for Online Communication with Patients.1
* Mobile health applications, distinct from regulated medical devices, may be defined as an application on a mobile device that is intended for use in the diagnosis of disease or other conditions, or in the cure, mitigation, treatment, or prevention of disease. The functions of these applications may include:
o The ability to store and track information about an individual or group's health or the social determinants thereof;
o Periodic educational information, reminders, or motivational guidance;
o GPS location information to direct or alert patients;
o Standardized checklists or questionnaires.2
* Mobile health applications can enhance health outcomes while mitigating health care costs because of their potential to improve a patient's access to information and care providers.3
* Mobile health applications are most commonly used on a smart phone and/or tablet. Some may also interface with medical devices.
* The use of mobile health applications reflects an emerging trend towards personalized medicine and patient involvement in the management of their health information. By 2016, 142 million health apps will have been downloaded.4 According to some industry estimates, by 2018, 50 percent of the more than 3.4 billion smartphone and tablet users worldwide will have downloaded at least one mobile health application.5
* While mobile health application downloads are increasing, there is little information about usage and adherence by patients. It is believed that many patients cease to use a mobile health application soon after downloading it.
* Distributers of mobile health applications do not currently assess content provided by mobile health applications for accuracy, comprehensiveness, reliability, timeliness, or conformity to clinical practice guidelines.6 However, mobile applications may be subjected to certain standards to ensure critical technical requirements such as accessibility, reachability, adaptability, operational reliability, and universality.
* Increasingly there are independent websites providing reviews of medical apps and checklists for health care professionals. However, the quality criteria used by these sites, potential conflicts of interest, and the scope and number of mobile apps assessed are not always declared by these groups.
To date, randomized controlled trials are not usually employed to assess the effectiveness of mobile health applications. Some believe that the rigorousness of this type of assessment may impede the timeliness of a mobile health application's availability.7
* Some examples of the uses of mobile health applications include tracking fitness activities to supplement a healthy lifestyle; supported self-management of health and health information; post-procedure follow up; viewing of test results; and the virtualization of interaction between patients and providers, such as remote patient monitoring for chronic disease management. Some mobile health applications may be linked to a patient profile or patient portal associated with a professional or recognized association or medical society or health care organization.
* Some mobile health applications may be an extension of an electronic medical records (EMR) platform.
* The objective of recommending a mobile health application to a patient must be to enhance the safety and/or effectiveness of patient care or otherwise for the purpose of health promotion.
* A mobile health application is one approach in health service delivery. Mobile health applications should complement, rather than replace, the relationship between a physician and patient.
* No one mobile health application is appropriate for every patient. Physicians may wish to understand a patient's abilities, comfort level, access to technology, and the context of the application of care before recommending a mobile health application.
* Should a physician recommend a mobile health application to a patient, it is the responsibility of the physician to do so in a way that adheres to legislation and regulation (if existing) and/or professional obligations.
* If the mobile health application will be used to monitor the patient's condition in an ongoing manner, the physician may wish to discuss with the patient what they should watch for and the steps they should take in response to information provided.
* Physicians are encouraged to share information about applications they have found effective with colleagues.
* Physicians who require additional information about the competencies associated with eHealth and the use of health information technologies may wish to consult The Royal College of Physicians and Surgeons of Canada's (RCPSC) framework of medical competencies, CanMEDS.8
* Physicians may wish to enter into and document a consent discussion with their patient, which can include the electronic management of health information or information printed out from electronic management platforms like mobile health applications. This agreement may include a one-time conveyance of information and recommendations to cover the elements common to many mobile health applications, such as the general risk to privacy associated with storing health information on a mobile device.
Characteristics of a safe and effective mobile health application
A mobile health application does not need to have all of the following characteristics to be safe and effective. However, the more of the following characteristics a mobile health application has, the likelier it will be appropriate for recommendation to a patient:
1. Endorsement by a professional or recognized association or medical society or health care organization
As recommended by the Canadian Medical Protective Association (CMPA), it is best to select mobile health applications that have been created or endorsed by a professional or recognized association or medical society.9 Some health care organizations, such as hospitals, may also develop or endorse applications for use in their clinical environments. There may also be mobile health applications associated with an EMR platform used by an organization or practice. Finally, some mobile health applications may have been subject to a peer review process distinct from endorsement by an association or organization.
There are a number of usability factors than can complicate the use of mobile applications, including interface and design deficiencies, technological restrictions, and device and infrastructure malfunction.
Many developers will release periodic updates and software patches to enhance the stability and usability of their applications. Therefore, it would be prudent for the physician recommending the mobile health application to also recommend to the patient that they determine if the application has been updated within the last year.
Physicians considering recommending a mobile health application to a patient may wish to ask about the patient's level of comfort with mobile health technologies, their degree of computer literacy, whether or not the patient owns a mobile device capable of running the application, and whether or not the patient is able to bear potential one-time or ongoing costs associated with use of the application.
Physicians may consider testing the application themselves beforehand to understand whether its functionality and interface make it easy to use.
3. Reliability of information
Physicians considering recommending a mobile health application may wish to understand how the patient intends to use the information, and/or review the information with the patient to understand whether it is current and appropriate.
Information presented by the mobile health application should be appropriately referenced and time-stamped with the last update by the application developer.
4. Privacy and security
In 2014, the Officer of the Information and Privacy Commissioner of Alberta assessed approximately 1200 mobile applications and found nearly one-third of them required access to personal information beyond what should be required relative to their functionality and purpose, and that basic privacy information was not always made available.10
Physicians entering into and documenting a consent discussion with their patients may wish to include the electronic management of health information in the scope of these discussions, and make a notation of the discussion in the patient's health record.
Some mobile health applications may feature additional levels of authentication for use, such as an additional password or encryption protocols. If all other factors between applications are equal, physicians may wish to recommend that patients use mobile health applications adhering to this higher standard of security.
5. Avoids conflict-of-interest
Physicians may wish to recommend that patients learn more about the company or organization responsible for the development of the application and their mandate. There is a risk of secondary gains by mobile health application developers and providers where information about patients and/or usage is gathered and sold to third parties.
A standardized conflict of interest statement may be made available through the mobile health application or on the developer's website. If so, physicians may wish to refer the patient to this resource.
Physicians who develop mobile applications for commercial gain or have a stake in those who develop applications for commercial gain may risk a complaint being made to the College on the basis that the physician engaged in unprofessional conduct if they recommend mobile health applications to their patients in the course of patient care.
6. Does not contribute to fragmentation of health information
Some mobile health applications may link directly to an EMR, patient portal, or government data repository. These data resources may be standardized, linked, and cross-referenced.
However, health information entered into an application may also be stored on a mobile device and/or the patient's home computer, or developers of mobile health applications may store information collected by their application separately. While there may be short-term benefits to using a particular mobile health application, the range of applications and developers may contribute to the overall fragmentation of health information.
If all other factors between applications are considered equal, physicians may wish to recommend mobile health applications which contribute to robust existing data repositories, especially an existing EMR.
7. Demonstrates its impact on patient health outcomes
While not all mobile health applications will have an appropriate scale of use and not all developers will have the capacity to collect and analyze data, physicians may wish to recommend mobile health applications that have undergone validation testing to demonstrate impact of use on patient health outcomes. If mobile health applications are claiming a direct therapeutic impact on patient populations, physicians may wish to recommend that their patients seek out or request resources to validate this claim.

The harms associated with psychoactive prescription medicinesi including sedatives and tranquilizers1, stimulants2, and analgesics, particularly opioids3, such as oxycodone, hydromorphone and fentanyl, are a significant public health and patient safety issue.
Canada has one of the highest per capita consumption of prescription opioids in the world.4 Dispensing of medications has substantially increased in Canada, although patterns vary considerably between provinces.5 In 2011, while opioid consumption for medical purposes in morphine equivalence (ME)ii was 62mg per person globally, Canada's ME was 812mg per person.6 When comparing to other developed countries, Australia's ME was 427 and Denmark's 483. In North America, about 5% of the adult population, and substantially higher rates for teens and young adults, reported non-medical opioid use in the previous year. This rate is higher than all other illegal drugs, with the exception of marijuana.7
Psychoactive medications pose significant health and safety risks. The harms include overdoses, suicides, motor vehicle accidents, relationship and employment problems, workplace accidents and exposure to blood borne pathogens and other infections when used by injection, besides addiction.
Data are not collected systematically in Canada, making it difficult to assess the harms and track the trends and impact of the introduction of policy changes. However, practitioners have seen the significant impact of these prescription drugs on their patients and to public health. Studies in Ontario show that the number of people enrolled in methadone maintenance treatment rose from about 7,800 in 2001 to over 35,000 in 2011, where opioids have surpassed heroin as the drug used.8 Opioid-related deaths nearly tripled from 2002 to 2010, according to the Office of the Chief Coroner of Ontario.9 Another study showed that other non-opioid depressants (sedatives), such as benzodiazepines, were involved in 92% of the opioid-related deaths.10
The impact is felt particularly among vulnerable populations, such as youth, seniors, First Nations and those living in poverty. In 2013, opioids were reported as the third most common drug used by students in Ontario (after alcohol and marijuana).11 Opioid addiction rates anywhere from 43% to 85% have been reported in some Indigenous communities.12 13 While accurate data on the harms of prescription medication among seniors is lacking, it is well known that the prevalence of pain is higher among older adults and that they account for a significant proportion of prescriptions.
The "high" they produce also leads to these medications being sought after for recreational purposes and, as they are legal products, they are often more easily accessible than street drugs. Surveys with youth have shown that as much as 70% of opioids have been obtained from legitimate prescriptions to family and friends (55% were shared at no cost).14 As well, because opioids have high abuse liability and addiction potential, people have resorted to illegal behaviour to obtain them, such as doctor-shopping, forging prescribers' signatures, or buying from street dealers.
Of great concern, opioid dispensing levels are strongly correlated with increased mortality, morbidity and treatment admissions for substance use.15 16 Studies in Ontario and British Columbia have replicated similar findings in the US. Many patients were prescribed these medications and developed dependence.17
Psychoactive medications are important therapeutic tools and serve legitimate purposes, when prescribed in an appropriate manner with proper assessment, and as part of a comprehensive therapeutic strategy and monitoring. Medications, such as opioids, have been essential in areas such as palliative and cancer care and have contributed to the alleviation of suffering.
Since the 1990s, opioids have been recommended for longer-term treatment of chronic non-cancer pain, and have become widely used due in part to aggressive promotion and marketing for this indication.18 19 However, there is evidence for significant pain relief in the short term but a need for more evidence regarding maintenance of pain relief over longer periods of time, or for improved physical function.20 21 22
Important contributing factors for the increase in prescriptions are also the lack of supports and incentives for the treatment of complex cases, including availability and funding for treatment options for pain and addictions. Alternate approaches to pain management require more time with the patient. In addition, there are new highly potent opioid drugs available.23 24
Canada's physicians are deeply concerned about the harms of opioids and other psychoactive prescription medications. As prescribers, they have a fundamental role in helping to ensure safe and effective use of these drugs, and the deterrence of abuse. 25 26 27 Physicians assess patients and consider whether a prescription is clinically indicated according to best practices, as well as consider whether the benefits outweigh the risks, while screening for risk factors for substance dependence and diversion. This area can be a source of tension with patients who might seek to obtain drugs through fraudulent means.28 It is also an area which causes concern to many physicians, and this could be affecting access to adequate pain management where it is needed.29
The challenge for physicians and public policymakers is how to mitigate the harms of psychoactive prescription drug use, while ensuring that patients have access to the appropriate treatment for their clinical conditions.
Comprehensive National Strategy
Canada's physicians believe that this challenge requires a complex and multifaceted solution; and to further such a solution, the CMA recommends that Canada have a comprehensive national strategy to address the harms associated with psychoactive drugs in Canada, whether illegal or prescription-based, complementing existing strategies to address the harms associated with the two legal drugs - alcohol and tobacco. This comprehensive approach is necessary, as isolated measures can have unintended consequences, such as under-medicating people that require a medical treatment or constraining people to seek illegal drugs as an option when medications are made tamper-resistant.
The federal government has created the National Advisory Council on Prescription Drug Misuse, co-chaired by the Canadian Centre on Substance Abuse, the Coalition on Prescription Drug Misuse (Alberta) and the Nova Scotia Department of Health and Wellness, in partnership with Health Canada's First Nations and Inuit Health Branch's Prescription Drug Abuse Coordinating Committee. In its 2013 report First Do No Harm: Responding to Canada's Prescription Drug Crisis30, there are nearly 60 recommendations toward the development of a strategy to combat the harms associated with psychoactive prescription medications. However, there is much still to be done.
The CMA supports collaborative efforts by the federal and provincial/territorial governments, and by health professionals and other stakeholders, to develop and implement a comprehensive national strategy. Such a strategy should include the following:
1. Improvement of Drug Safety
Health Canada, as the agency that approves prescription drugs for use and monitors their safety once on the market, has several levers by which it can control Canadians' access to drugs. One of these is the Controlled Drugs and Substances Act (CDSA) and its regulations, which govern access to illegal products and recently has included psychoactive prescription drugs.
Because of their health and safety risks, it is important that Health Canada ensures that the CDSA subjects psychoactive substances to high levels of regulatory scrutiny during both the approval process and post-approval surveillance. The Act should require manufacturers to:
* Meet stringent pre-approval requirements. For example, Health Canada could require intensive review of pre-approval clinical trial results and of product monographs by an expert impartial review committee (including addiction, pain and public health expertise); or require that the manufacturer fulfill special conditions, such as formal post-market studies, as a condition of the drugs' approval; or even require larger sample sizes or longer study periods to assess harms;
* Adhere to restrictions on the marketing of controlled medications to health professionals and the general public. The adequacy of regulations needs to be assessed in this regard.
* Develop and cover tamper-resistant formulations of psychoactive drugs of concern. Although not a standalone solution, tamper-resistant formulations can reduce the potential for manipulation to be able to use through snorting, chewing or intravenously.
2. Enhancement of Optimal Prescribing through Evidence-Based Guidance, Education and Support for Prescribers
CMA recommends that appropriate prescribing of psychoactive medications should be addressed through evidence-based guidance and education. A strategy to support optimal therapy might include:
* Support for models of care that allow a physician to spend time with complex patients.
* Ongoing development and dissemination of clinical guidance. The Canadian Guideline for Use of Opioids to Treat Chronic Non-Cancer Pain was published in the CMAJ in 2010. CMA has co-sponsored an online CME module based on this guideline. There is interest in similar guidelines for sedatives and stimulants.
* Evaluative research to support the critical review of guidelines periodically. It is essential to review data on chronic conditions for which risks might outweigh benefits.
* Relevant, unbiased and easily accessible information for prescribers, which can readily be incorporated into everyday practice. This should include clinical decision-support tools for use at the point of care, inclusive of dosing guidelines and guidance on when to seek consultation with experts. Physicians also require tools, including those that facilitate: monitoring of effectiveness and tolerance by tracking pain and physical function; screening for past and current substance use; screening for depression; tapering of problematic or ineffective doses; among others.
* Educational programs in optimal prescribing, pain management and in the management of addictions, as part of the curriculum in medical school, and residency training as well as in continuing education. Particular support is needed for those in primary care.
* Guidance for prescribers about how to deal with conflict in their practice. This would include guidance for patient-centred educational discussions on safe opiate prescribing and use and management of addictions.
* Access to expert advice if required through such means as:
o Policies or standards of practice developed by provincial regulatory colleges of physicians, which can include limitations on prescription volume, treatment period and indications.
o Communities of practice, knowledge hubs and clinical support networks that link practitioners with experts in the field, facilitating triage and supporting front line generalists. Experts can not only provide clinical information, but can provide mentorship and personal advice about best practices.
o Feedback to practitioners about their prescribing practices, particularly if potentially concerning patterns are identified. This initiative should be facilitated by collaborative work between health care professionals and their respective provincial regulatory colleges.
o Academic detailing programs, which use personalized, one-on-one techniques to deliver impartial prescribing information to practitioners.
3. Enhancement of Optimal Prescribing through Physician Regulation and Prescription Monitoring Programs
Medicine is a regulated profession, and the provincial colleges of physicians have ultimate authority and responsibility for the oversight of physician practice. The colleges have taken a leading role in educating their members about appropriate prescribing, in monitoring prescribing practices to ensure their appropriateness and taking disciplinary action when required, and through collaborating with law enforcement agencies to detect and halt criminal diversion.
The CMA recommends that federal and provincial regulations regarding controlled substances recognize the established authority of physician regulatory colleges for the oversight of the medical profession.
While prescription monitoring programs (PMPs) exist in most provinces, they vary considerably in terms of quality, the nature of the information they require, whether health care practitioners have real-time access, and the purpose for which the data are collected. Standardization of monitoring systems across Canada according to best practices can contribute to addressing the harms associated with psychoactive prescription medication by:
* Allowing health care practitioners to identify previous or concomitant prescriptions of controlled medications with more than one practitioner at the time the prescription is requested or filled;
* Deterring interprovincial or jurisdictional fraud, by allowing health care practitioners to identify other prescriptions at the time the prescription is requested or filled; and
* Improving professional regulatory bodies' capacity for oversight and intervention by establishing a mechanism for real-time monitoring.
The CMA recommends that all levels of government work with one another and with health professional regulatory agencies to develop a pan-Canadian system of real-time prescription monitoring. As a first step, the CMA recommends the establishment of consistent national standards for prescription monitoring.
PMPs should be compatible with existing electronic medical and pharmacy record systems and with provincial pharmaceutical databases. Participation in prescription monitoring programs should not impose an onerous administrative burden on health care providers. PMPs should not deter physicians from using controlled medications when necessary.
CMA also recommends that Health Canada ensure that its legislative framework be used to facilitate and support the advancement of e-health, specifically e-prescribing. Electronic health records can help individual physicians or pharmacists identify potential diversion and double prescriptions, at the point where a prescription is written or filled. The electronic health record also facilitates the sharing of information among health professionals, and could minimize the potential administrative burden.
PMPs should conform to privacy laws, protecting patient confidentiality while enabling the sharing of necessary information. The CMA strongly recommends that Health Canada undertake a privacy impact assessment of the regulatory framework for controlled prescription drugs, and share the results with stakeholders.
4. Increase in Access to Treatment for Pain
Chronic pain affects many aspects of a person's life including their ability to work, their emotional, mental and physical health, and their quality of life. Pain costs Canada an estimated $60 Billion dollars per year; more than the cost of heart disease, cancer and diabetes.31 CMA has endorsed a national strategy for pain, developed and proposed by the Canadian Pain Coalition and Canadian Pain Society,32 which addresses four target areas: awareness and education; access; research; and ongoing monitoring.
Experts believe that improved access to specialized pain treatment could reduce inappropriate use of pain medications. Current best practices in pain management include:
* Care by an interprofessional team that could include physiotherapists, occupational therapists, psychologists and other health professionals;
* Recommendation of non-pharmaceutical interventions such as therapy for trauma and social pain, social supports and coping strategies;
* Appropriate pharmaceutical prescription options, covered by provincial formularies; and
* A focus on patient participation and empowerment.
However, specialized pain treatment programs are in short supply. Wait times are greater than one year at more than one third of publicly funded inter-professional treatment programs.33 In many parts of Canada, particularly rural and remote areas, such programs are not available. In addition, while physician visits are covered by the public health care system, services provided by other health professionals are more likely to be either covered by private health benefits or paid out of pocket, and are therefore beyond the means of many Canadians. These factors may result in heavier reliance on prescription medication as treatment for chronic pain.
The CMA recommends that all partners work to improve and promote access to specialized treatment programs for pain management, and that investments be made in research about options for treatment.
5. Increase in Access to Treatment for Addiction
Access to addiction treatment is very limited and, when available, is primarily comprised of detox or the substitution treatments with methadone or Suboxone(r) (buprenorphine and naloxone). As addiction is a primary, chronic disease of brain reward, motivation, memory and related circuitry by definition, which manifests along biological, psychological, social and spiritual dimensions, treatment must address all those areas rather than just one or another.34
The CMA supports the enhancement of access to options for addiction treatment that address different needs. Treatment programs must be coordinated and patient-centred, and address physical, psychological, social and spiritual circumstances. For example, it is important that addiction programs be culturally relevant for Indigenous communities.
Treatment programs must also be integrated within the health care system and be adequately funded to meet evidence based, best-practice guidelines.
CMA also supports the development and dissemination of practice tools and guidelines to help physicians assess the addiction potential of a patient receiving psychoactive medications, and to assist in managing patients who have addiction and related problems and complications.
6. Increase in Information through Epidemiological Surveillance
One of the challenges in dealing with prescription drug abuse, which can reflect hazardous (episodic) use, harmful (regular) use or addiction, is the incompleteness of our knowledge of the extent of the problem. Countries, such as the US and France, are able to monitor psychoactive drug use, while in Canada we still rely on unsystematically collected or locally limited data. The creation of a national surveillance system that supports the collection of systematic, standardized information would:
* Permit the thorough assessment of the problem, with the development and monitoring of indicators;
* Support the early detection of diversion or inappropriate prescribing behaviour;
* Support the establishment of best practices to address crucial issues;
* Identify research priorities; and
* Evaluate the impact of the implementation of strategies.
Sources of information should include PMPs, coroner's investigations, emergency room admissions, and poison control data, among others.
7. Prevention of Deaths due to Overdose
Overdose deaths have increased dramatically over the past ten years. The risk of harm from overdose may be compounded if recreational users are afraid to call for emergency assistance for fear of facing criminal charges. Opioid death and complications overdoses can be prevented with appropriate medication and prompt emergency response. The CMA recommends the:
* Creation and scaling up of community-based programs that offer access to naloxone and other opioid overdose prevention tools and services. Training should be made available to health workers, first responders, as well as opioid users, families and peers about the prevention of overdose fatalities.35
* Improvement of access to naloxone to reverse opioid overdoses. This should include the prescription of naloxone to high risk individuals and third parties who can assist a victim experiencing an opiate-related overdose.
* Enactment of Good Samaritan laws by all levels of government in order to protect callers from criminal charges if they call emergency services to report an overdose. 36 37
8. Provision of Information for Patients and the Public
Awareness programs that provide accurate information to patients and the general public are important, and could include:
* Information on the benefits and harms of psychoactive prescription medication use, and signs of dependence and overdose. This should include the risk of dependence and addiction associated with the use of opiates for the treatment of acute and chronic pain.
* Messages aimed at the prevention of problematic drug use among young people and other populations at risk.
* Information regarding safe medication storage and disposal, and reducing access to medications from family and friends. CMA supports national prescription drug "drop off" days, and recommends that patients be educated about the importance of routinely returning unused prescription drugs to the pharmacy.
The CMA recommends that Canada have a comprehensive national strategy to address the harms associated with psychoactive drugs in Canada, whether illegal or prescription-based. This strategy should include:
* That Health Canada require that manufacturers meet stringent pre-approval requirements, adhere to restrictions on the marketing of controlled medications to health professionals and the general public, and develop formulations of psychoactive drugs of concern that are tamper-resistant.
* Support for optimal prescribing through evidence-based guidance, education and supports, such as clinical guidance, clinical decision-support tools, educational programs, expert advice, and supportive models of care.
* The enhancement of optimal prescribing through physician regulation and the development of a pan-Canadian system of real-time prescription monitoring programs, compatible with electronic medical and pharmacy record systems, based on national standards.
* Increased access to specialized pain management and treatment, according to best practices, with investments in research.
* The enhancement of access to options for addiction treatment that address different needs, and the support for the development and dissemination of practice tools and guidelines.
* The creation of a national surveillance system that supports the collection of systematic, standardized information to better inform and track policy changes.
* The creation and scaling up of community-based programs that
* Offer access to opioid overdose prevention tools and services, including the improvement of access to medication to reverse opioid overdoses (naloxone) and the enactment of Good Samaritan laws by all levels of government.
* The provision of accurate information to patients and the general public, including safe medication storage and disposal.
i Psychoactive drugs are substances that, when taken, have the ability to change an individual's consciousness, mood or thinking processes (WHO, 2004). Psychoactive prescription drugs include sedatives (such as benzodiazepines and barbiturates), stimulants (such as amphetamines), and opioids (such as oxycodone, hydromorphone, morphine and fentanyl). [World Health Organization (2004) Neuroscience of psychoactive substance use and dependence. Available at: http://www.who.int/substance_abuse/publications/en/Neuroscience.pdf]
ii Comprises six main opioids: fentanyl, hydromorphone, methadone, morphine, oxycodone and pethidine.

In 2010, 14% of Canada's population was 65 or older. With the aging of the baby boom generation, this proportion is estimated to rise to about 25% in 2036 (1). The aging of Canada's population is expected to have a major impact on the country's economy, society and health care system over the next 25 to 30 years.
Though age does not automatically mean ill health or disability, the risk of both does increase as people age. In 2006, 33% of Canadians aged 65 or older had a disability; the proportion climbed to 44% among people aged 75 or older (2). Nearly three-quarters of Canadians over 65 have at least one chronic health condition (3). Because of increasing rates of disability and chronic disease, the demand for health services is expected to increase as Canada's population ages. Currently Canadians over 65 consume roughly 44% of provincial and territorial health care budgets (4), and governments are concerned about the health care system's capacity to provide quality services in future.
The CMA believes that to provide optimal care and support for Canada's aging population, while taking care to minimize pressure on the health-care system as much as possible, governments at all levels should invest in:
* programs and supports to promote healthy aging;
* a comprehensive continuum of health services to provide optimal care and support to older Canadians; and
* an environment and society that is "age friendly."
This policy describes specific actions that could be taken to further these three goals. Its recommendations complement those made in other CMA policies, including those on "Funding the Continuum of Care" (2009), Optimal Prescribing (2010) and Medication Use and Seniors (Update 2011).
2) Providing Optimal Health and Health Care for Older Persons:
This section discusses in detail the three general areas in which the CMA believes governments should invest:
a) Promotion of "Healthy Aging"
The Public Health Agency of Canada (PHAC) defines healthy aging as "the process of optimizing opportunities for physical, social and mental health to enable seniors to take an active part in society without discrimination and to enjoy independence and quality of life." It is believed that initiatives to promote healthy aging, and enable older Canadians to maintain their health, will help lower health-care costs by reducing the overall burden of disability and chronic disease. Such initiatives could focus on:
Physical activity. Being physically active is considered the most important step that older Canadians can take toward improving health, even if they do not start being active until later in life. However in 2008, 57% of seniors reported being physically inactive (5).
Injury prevention. Falls are the primary cause of injury among older Canadians; they account for 40% of admissions to nursing homes, 62% of injury-related hospitalizations, and almost 90% of hip fractures (6). The causes of falls are complex, and both physiology (e.g. effect of illness) and environment (e.g. poorly maintained walkways) can contribute. Most falls can be prevented through a mix of interventions: for the person (such as strength and balance training); and for the person's environment, (such as grab bars and railings, slip-proof floor surfaces, walkways that are cleared of snow and ice in winter.)
Nutrition. In 2008, 28% of men and 31% of women over 65 were obese (BMI = 30); this is higher than the population average. Underweight is also a problem among seniors, 17% of whom report a BMI of 20 or less (7). The reasons for nutrition problems among older Canadians are complex; they may be related to insufficient income to purchase healthy foods, or to disabilities that make shopping or preparing meals difficult.
Mental health. An estimated 10-15% of seniors report depression, and the rate is higher among those with concomitant physical illness, or those living in long-term care facilities (8). Depression among older people may be under-recognized and under-treated, since it might be dismissed as a normal consequence of aging. Poor mental health is often associated with social isolation, a common problem among seniors.
Governments and National Associations
The CMA recommends that:
1. Governments at all levels support programs to promote physical activity, nutrition, injury prevention and mental health among older Canadians.
Health Service Delivery
The CMA recommends that:
2. Older Canadians have access to high-quality, well-funded programs and supports to help them achieve and maintain physical fitness and optimal nutrition.
3. Older Canadians have access to high-quality, well-funded programs aimed at determining the causes and reducing the risk of falls.
4. Older Canadians have access to high-quality, well-funded programs to promote mental health and well-being and reduce social isolation.
Physicians and Patients
The CMA recommends that:
5. Older Canadians be encouraged to follow current guidelines for healthy living, such as the 2012 Canadian Physical Activity Guidelines for adults 65 and over.
6. Physicians and other health care providers be encouraged to counsel older patients about the importance of maintaining a healthy and balanced life style.
7. All stakeholders assist in developing health literacy tools and resources to support older Canadians and their families in maintaining health.
b) A Comprehensive Continuum of Health Services
Though, as previously mentioned, age does not automatically mean ill health, utilization of health services does increase with increasing age. Patients over 65 have more family physician visits, more hospital admissions and longer hospital stays than younger Canadians (the overall length of stay in acute inpatient care is about 1.5 times that of non-senior adults) (9).
In addition, seniors take more prescription drugs per person than younger adults; 62% of seniors on public drug programs use five or more drug classes, and nearly 30% of those 85 and older have claims for 10 or more prescription drugs (10). Heavy medication use by people over 65 has a number of consequences:
* The risk of adverse drug reactions is several-fold higher for seniors than for younger patients.
* Medication regimes, particularly for those taking several drugs a day on different dosage schedules, can be confusing and lead to errors or non-adherence.
* Patients may receive prescriptions from multiple providers who, if they have not been communicating with each other, may not know what other medications have been prescribed. This increases the risk of harmful drug interactions and medication errors.
For seniors who have multiple chronic diseases or disabilities, care needs can be complex and vary greatly from one person to another. This could mean that a number of different physicians, and other health and social-services professionals, may be providing care to the same person. A patient might, for example, be consulting a family physician for primary health care, several medical specialists for different conditions, a pharmacist to monitor a complex medication regime, a physiotherapist to help with mobility difficulties, health care aides to clean house and make sure the patient is eating properly, and a social worker to make sure his or her income is sufficient to cover health care and other needs.
Complex care needs demand a flexible and responsive health care system. The CMA believes that quality health care for older Canadians should be delivered on a continuum from community based health care, (e.g. primary health care, chronic disease management programs), to home care (e.g. visiting health care workers to give baths and footcare), to long-term care and palliative care. Ideally, this continuum should be managed so that the patient can remain at home, out of emergency departments, hospitals and long term care unless appropriate, can easily access the level of care he or she needs, and can make a smooth transition from one level of care to another when needed.
Care managers are an essential part of this continuum, working with caregivers and the patient to identify the most appropriate form of care from a menu of alternatives. Care managers can co-ordinate the services of the various health professionals who deliver care to a given patient, and facilitate communication among them so that all work to a common care plan. A family physician who has established a long-standing professional relationship with the patient and is familiar with his or her condition, needs and preference is ideally placed to serve as manager of a patient's overall care, supported by geriatric and other specialists as appropriate.
Not all of the patient's caregivers may be health professionals; more than 75% of the care of older Canadians is delivered by unpaid informal caregivers, usually relatives. The role of the family caregiver can be demanding financially, physically and emotionally. Though governments have instituted tax credits and other forms of support for caregivers, more may be required. The Special Senate Committee on Aging has called for a National Caregiving Strategy to help put in place the supports that caregivers need. (11)
Finally, many of the services required by seniors, in particular home care and long-term care, are not covered by the Canada Health Act. Funding of these services varies widely from province to province. Long-term care beds are in short supply; as a result more than 5,000 hospital beds are occupied by patients waiting for long-term care placement (12), making them unavailable for those with acute-care needs. CMA's Health Care Transformation Framework (2010) makes a number of recommendations aimed at improving access to continuing care in Canada.
Governments and National Associations
The CMA recommends that:
8. Governments and other stakeholders work together to develop and implement models of integrated, interdisciplinary health service delivery for older Canadians.
9. Governments continue efforts to ensure that older Canadians have access to a family physician, supported by specialized geriatric services as appropriate.
10. Governments and other stakeholders work together to develop and implement a National Caregiver Strategy, and expand the support programs currently offered to informal caregivers.
11. All stakeholders work together to develop and implement a national dementia strategy.
12. Governments and other stakeholders work together to develop and implement a pan-Canadian pharmaceutical strategy that addresses both comprehensive coverage of essential medicines for all Canadians, and programs to encourage optimal prescribing and drug therapy.
13. Governments work with the health and social services sector, and with private insurers, to develop a framework for the funding and delivery of accessible and sustainable home care and long-term care services.
The CMA recommends that:
14. Medical schools enhance the provision, in undergraduate education and in residency training for all physicians, of programs addressing the clinical needs of older patients.
15. Medical students and residents be exposed to specialty programs in geriatric medicine and other disciplines that address the clinical needs of older patients.
16. Continuing education programs on care for older patients be developed and provided to physicians of all specialties, and to other health care providers, on a continuous basis.
Health System Planners
The CMA recommends that:
17. Health systems promote collaboration and communication among health care providers, through means such as:
a. Interdisciplinary primary health care practice settings, that bring a variety of physicians and other health professionals and their expertise into a seamless network;
b. Widespread use of the electronic health record; and
c. A smooth process for referral between providers.
18. All stakeholders work toward integration of health care along the continuum by addressing the barriers that separate:
a. acute care from the community;
b. health services from social services; and
c. provincially-funded health care services such as physicians and hospitals, from services funded through other sources, such as pharmacare, home care and long term care.
19. Programs be developed and implemented that promote optimal prescribing and medication management for seniors.
20. Research be conducted on a continuous basis to identify best practices in the care of seniors, and monitor the impact of various interventions on health outcomes and health care costs.
Physicians in Practice
The CMA recommends that:
21. Continuing education, clinical practice guidelines and decision support tools be developed and disseminated on a continuous basis, to help physicians keep abreast of best practices in elder care.
c) An Age-Friendly Environment:
One of the primary goals of seniors' policy in Canada is to promote the independence of older Canadians in their own homes and communities, avoiding costly institutionalization for as long as feasible. To help older Canadians successfully maintain their independence, it is important that governments and society ensure that the social determinants of health care addressed when developing policy that affects them. This includes assuring that the following supports are available to older Canadians:
* Adequate Income: Poverty among seniors dropped sharply in the 1970s and 1980s. In 2008, 6% of Canada's seniors were living in low income, as opposed to nearly 30% in 1978. However, there has been a slight increase in poverty levels since 2007, and it may be necessary to guard against an upward trend in future (13). Raising the minimum age for collecting Old Age Security, as has been proposed, may weigh heavily on seniors with lower incomes, and make prescription drugs, dental care and other needed health services unaffordable.
* Employment Opportunities: it has been recommended that seniors be encouraged to work beyond age 65 as a means of minimizing a future drain on pension plans (14). Many older Canadians who have not contributed to employee pension plans may be dependent on employment income for survival. However, employment may be difficult to find if workplaces are unwilling to hire older workers.
* Housing. Nearly all of Canada's seniors live in their own homes; fewer than 10% live in long-term care facilities. Options are available that permit older Canadians to live independently even with disabilities and health care needs, such as:
o Home support for services such as shopping and home maintenance; and
o Assisted-living facilities that provide both independent living quarters and support services such as nursing assistance, and cafeterias if desired.
* An Age-friendly built environment. To enable seniors to live independently, the World Health Organization's "Age-Friendly Communities" initiative recommends that their needs be taken into consideration by those who design and build communities. For example, buildings could be designed with entrance ramps and elevators; sidewalks could have sloping curbs for walkers and wheelchairs; and frequent, accessible public transportation could be provided in neighbourhoods where a large concentration of seniors live.
* Protection from Abuse. Elder abuse can take many forms: physical, psychological, financial, or neglect. Often the abuser is a family member, friend, or other person in a position of trust. Researchers estimate that 4 to 10% of Canadian seniors experience abuse or neglect, but that only a small portion of this is reported (15). CMA supports awareness programs to bring the attention of elder abuse to the public, as well as programs to intervene with seniors who are abused, and with their abusers.
* A Discrimination-Free society. Efforts to boost income and employment security, health care standards and community support for older Canadians are hampered if the pervasive public attitude is that seniors are second-class citizens. An age-friendly society respects the experience, knowledge and capabilities of its older members, and accords them the same worth and dignity as it does other citizens.
Governments and National Associations
The CMA recommends that:
22. Governments provide older Canadians with access to adequate income support.
23. Governments devote a portion of national infrastructure funding to providing an adequate supply of accessible and affordable housing for seniors.
24. Older Canadians have access to opportunities for meaningful employment if they desire.
25. Communities take the needs and potential limitations of older Canadians into account when designing buildings, walkways, transportation systems and other aspects of the built environment.
Health System Planners
The CMA recommends that:
26. The health system offer a range of high-quality, well-funded home care and social support services to enable older Canadians to remain independent in the community for as long as possible.
27. Physicians receive advice and education on optimal community supports and resources to keep seniors independent and/or at home.
Physicians in Practice
The CMA recommends that:
28. Training and programs be provided to physicians and other care providers to enable them to identify elder abuse, and to intervene with abused people and their abusers.
Aging is not a disease, but an integral part of the human condition. To maximize the health and well-being of older Canadians, and ensure their continued functionality and independence for as long as possible, CMA believes that the health care system, governments and society should work with older Canadians to promote healthy aging, provide quality patient-centered health care and support services, and build communities that value Canadians of all ages.

HEALTH IN ALL POLICIES
Despite significant investments in health and improvements in medical treatment and technologies, health outcomes in Canada have not been moving in the right direction. Chronic diseases such as diabetes and the corresponding risk factors, among them obesity, continue to rise. This negative health status can undermine not only individual health but the productivity and prosperity of the country as well.1 As noted in the Adelaide Statement on Health in All Policies, "Good health enhances quality of life, improves workforce productivity, increases the capacity for learning, strengthens families and communities, supports sustainable habitats and environments, and contributes to security, poverty reduction and social inclusion."2
Research suggests that 15% of population health is determined by biology and genetics, 10% by physical environments, 25% by the actions of the health care system, with 50% being determined by our social and economic environment.3 Many studies show that people low on the socio-economic scale are likely to carry a higher burden of just about any disease.4 Poverty accounts for 24% of person years of life lost in Canada (second only to 30% for neoplasms).5 These numbers demonstrate a need to rethink the way we work to improve the health of the Canadian population. While a strong health care system is vital, changes to our health system alone will not be sufficient to improve health outcomes or reduce the disparities that currently exist in disease burden and health risks.
Using health determinants as a focus means that most health promotion and prevention efforts will take place outside of the health and medical care service.6 Canadians must be supported to make the choices that keep them healthy and reduce their risks of injury and disease. However, many face barriers in their physical, social and economic environments which make these healthy choices difficult. What is necessary is a coordinated effort across government sectors to ensure that all policy decisions serve to increase opportunities for health. As noted by the former Minister of Health and Welfare, Jake Epp, "it is not an overstatement to say that public policy has the power to provide people with the opportunities for health, as well as to deny them such opportunities... All policies having a direct bearing on health need to be coordinated."7
Improving population health and reducing inequities should be an overall objective for all governments in Canada. Not only will it help to reduce costs to the health system, it will also increase economic growth as healthier people lose fewer days of work and contribute to overall economic productivity.8 As laid out in the principles to Guide Health Care Transformation, "Coordinated investments in health promotion and disease and injury prevention, including attention to the role of the social determinants of health, are critical to the future health and wellness of Canadians and to the viability of the health care system.9"
The utilization of such an approach is not new. Governments from England to Finland to New Zealand have increasingly recognized the importance of the social determinants of health and have developed national strategies accordingly. These strategies, often referred to as 'health in all policies,' call for a whole of government approach where cross-departmental collaboration is established at the highest government level to increase the health of the population and reduce inequalities.10 The World Health Organization defines health in all policies as follows:
Health in all Policies (HiAP) is an approach to public policies across sectors that systematically takes into account the health and health systems implications of decisions, seeks synergies, and avoids harmful health impacts, in order to improve population health and health equity. A HiAP approach is founded on health-related rights and obligations. It emphasizes the consequences of public policies on health determinants, and aims to improve the accountability of policy-makers for health impacts at all levels of policy-making.11
This approach looks at all policies that have a health impact not just those in the health sector. Policies are reviewed for their potential impact on population health and health system utilization.12
There are many ways that a HiAP approach can be implemented. Examples include:
inter-ministerial and inter-departmental committees; community consultations and Citizens' Juries; cross-sector action teams; partnership platforms; integrated budgets and accounting; Health Lens Analyses; cross-cutting information and evaluation systems; impact assessments; joined-up workforce development; and legislative frameworks.13
A Plan for Canada
Role of the Federal Government:
While the provinces and territories have constitutional authority for the majority of health system delivery, the federal government has a significant role in health: through system oversight, Canada Health Act; delivery to certain populations, Canada's Aboriginal peoples; as well as accountability and pan-Canadian initiatives for the various health systems. Additionally, the federal government has significant control over areas such as taxation, food security and agriculture, justice, transportation safety and income security (eg child tax benefits, Old- Age Security). All of these can have a marked impact on both individual and population health.
As a result of these responsibilities the Canadian government needs to adopt a clear mandate to focus on the health of the population. Actions must be taken to provide Canadians with the ability to make healthy choices. All legislation must be subject to a health lens to determine potential health implications so as to minimize or mitigate any negative consequences and maximize opportunities for health benefits. Given the central coordinating function of Cabinet in policy setting and delivery, this would be an ideal place to incorporate a HiAP approach.
1. CMA recommends that the federal government acknowledge the relationship of the social determinants of health on the health of the population as well as the demands of the health care system and that it implement a Health in All Policies approach for all cabinet decision-making.
While Cabinet should serve as the central decision-making body for a HiAP approach, there must be formal and sustainable structures that allow timely analysis of the health consequences of policy decisions, which appropriately engage stakeholders, and which ensure that health impacts are actually considered in policy decision-making.14
Such an approach will require some form of enabling legislation as well as benefits for departments that conduct HiAP analysis. In Quebec, for example, all policies are required to undergo a review of health impacts under Section 54 of the 2002 Quebec Public Health Act.15
In addition, it is likely that a lead agency will need to be appointed to facilitate the necessary data collection/analysis to review policies. In the Netherlands health impact assessments are the responsibility of the Department of Intersectoral Policy at the Netherlands School of Public Health.16 Since 2000, the Swedish National Public Health Institute (SNIPH) has been tasked with developing methodology in strategically important areas and with supporting the application of health assessments on the central, regional and local level.17 In England, the Public Health Observatories play a key role in providing data and analysis for health impact assessments.18
A significant barriers to HiAP in Canada is the existing data infrastructure. Hundreds of major and minor publications speak to the volume of analyses undertaken on health and health systems every year in Canada. Despite this effort, Canadian policy makers and the public do not fully understand how health system vs. non-health factors contribute to the health outcomes observed or the picture of overall health. The available data tends to focus on the health care system, sickness and the measurement of sickness related risks. What is missing is a way of organizing the data which provides greater insight for planners and greater accountability for all Canadians. This capacity will need to be developed in order to properly implement a HiAP approach.
2. CMA recommends that the federal government provide the necessary enabling environment to allow for the application of a health in all policies approach in all new policy development.
As the experiences from other countries demonstrate there is some value in selecting a few Ministries to begin the process. Once selected the Ministries should be responsible for starting the process and screening any new policies. If there is a potential health impact they would then contact the centralized resource to conduct the analysis and produce a report with potential impacts and recommendations for change. This report would go back to the originating Ministry for review and modification of the policy as necessary. Changes should be highlighted and the revised policy should be sent with the health analysis report to Cabinet for final decision-making. This will help to improve the policy and will create greater awareness among all Cabinet members of the potential health implications of various policies.
3. CMA recommends that the Federal Minister of Health work with Cabinet to select appropriate Ministries to begin the implementation of the health in all policies approach.
Role of Health Care Sector:
Government is not the only group with a role in HiAP. The health sector, including Canada's physicians can work to ensure that the policy environment promotes health. By working with governments at all levels, physicians can uses their vast knowledge and expertise to provide evidence regarding potential health implications, and promote the development of evidence-informed decision making. In addition, they can work with partners both within and outside of the health sector to advocate as necessary for policy improvements.19
4. CMA recommends that physicians and other health care providers use their knowledge and expertise to support governments in the development of evidence-informed policy which promotes the health of the population.
Investments in the health system will only go so far in improving the health of the population. Population health approaches must tackle the wider social determinants of health. To do so the government must consider health in all the policies that it develops.

The Canadian Medical Association (CMA) supports the promotion of healthy lifestyles in order to improve individual health and well-being and the overall health status of the population. Healthy lifestyles refer to patterns of individual practices and personal behavioural choices that are associated with optimal health. Two of the most important behaviours to create or maintain optimum health are healthy eating and physical activity.
For many Canadians, their diet and physical activity levels can have a negative rather than positive impact on their overall health. There is a particular concern for children and youth who are growing up in increasingly obesogenic environments that reinforce practices that work against a healthy lifestyle.1 Childhood obesity research tells us that overweight and obese children are more likely to stay the same into adulthood.2 To reverse this trend, determined action is required for children and youth to learn and acquire healthy behaviours that they will maintain throughout their life. Healthy lifestyles are central to successful aging and improving the likelihood of recovery after poor health.3
This policy paper discusses the importance of physical activity and healthy eating, and the role that individuals and families, schools, workplaces, communities, the food industry and all levels of governments can play in promoting healthy lifestyles. We know that collaborative action is required to make it easier for Canadians to incorporate healthy eating and physical activity into their daily lives - to make the healthy choice the easy choice.
What are the health impacts of unhealthy diets and physical inactivity
Diet is the leading risk factor for death, disability and life-years lost; being estimated to cause over 65,000 deaths and 864,000 life years lost in Canada in 2010.4
Unhealthy diet has been consistently linked with cardiovascular diseases (heart disease, stroke, hypertension, diabetes, dyslipidemia) and some cancers,5 which constitutes the majority of the disease burden in Canada. An estimated 80% of hypertension, which affects over 7 million Canadians, is directly or indirectly attributed to unhealthy diet.6
An estimated 60% of Canadian adults and close to one-third of children are overweight or obese, largely caused by unhealthy diets.7 Overweight and obesity (and the lifestyle choices associated with them) are contributors to more than 18 chronic conditions.8 This includes diabetes, cardiovascular disease, hypertension and liver disease, as well as breast, colon and prostate cancer.
Obesity is a public health issue not unique to Canada as the rates are increasing worldwide. Obesity is generally attributed to the fact that, as a society, we are increasing our calorie intake while at the same time burning less energy in physical activity. While it is difficult to determine how many deaths are directly attributable to obesity, we know that obesity often co-exists with other risk factors such as the lack of physical activity.
Exercise is one of the top modifiable risk factor for chronic disease.9 Regular physical activity is associated with a reduced risk of cardiovascular disease, some types of cancer, diabetes, obesity, hypertension, bone and joint diseases, and depression.10 The risk for many of these conditions is reduced by 20 - 40% in adults with the highest levels of physical activity compared to those with the lowest levels of physical activity. Recent research has shown that a sedentary lifestyle is associated with higher risk for chronic conditions such as obesity, diabetes and cancer independent of physical activity levels.11
According to the most recent Canadian Health Measures Study physical activity levels for children and youth are low with 6 out of 10 waking hours devoted to sedentary pursuits. Obesity is rising and physical fitness is declining.12
Canadians who do not achieve adequate levels of physical activity or eat unhealthy foods are vulnerable to preventable chronic diseases, premature death, and contribute to high health care costs. For instance, in 1999, $2.1 billion or 2.5% of the total direct health care costs were attributable to physical inactivity.13
To understand why the rates of obesity and overweight are rising, it may be helpful to look at what we already know about healthy eating and physical activity.
What we know about healthy eating
While modern science has allowed us to expand our knowledge of the impact of nutrients and food on human health we continue to be beset with illness and disease caused by the foods we consume. Having the right amount and type of food recommended in Canada's Food Guide is a first step towards healthy eating. But Canadians self-reported dietary intakes do not meet national dietary recommendations despite high reliance on public education concerning healthy eating and healthy diets. Children and adults are under-consuming the recommended servings of vegetables and fruits, an established proxy for healthy eating habits, and exceeding daily recommended intakes of sodium.14,15
As the links between nutrition and disease, and the impact on the health of our society are revealed it is more important than ever to understand what influences healthy eating behaviours. Food choices are structured by a variety of individual determinants of behaviour, ranging from one's physiological state, food preferences, nutritional knowledge, perceptions of healthy eating and psychological factors.
Many processed foods have become popular due to their accessibility and 'convenience factor', but these features have changed the way food and in particular these products are consumed compared to unprocessed foods: increased 'grazing', eating alone or eating while carrying out other activities such as work or driving. In addition, many calories consumed come in liquid form.16
Growth in the production and consumption of ultra-processed foods has increased drastically in the last decades in both higher and lower-income countries.17 A number of studies have shown that because less healthy foods are cheaper than healthier food, individuals from lower socioeconomic classes tend to be more dependent on unhealthy foods for nourishment.18
Other determinants for healthy eating include a wide range of contextual factors, such as the interpersonal environment created by family and peers, the physical environment, which determines food availability and accessibility, the economic environment, in which food is a commodity to be marketed for profit, and the social environment. Within the social environment, social status (income, education and gender) and cultural milieu are determinants of healthy eating that may be working "invisibly" to structure food choice.19
What we know about physical activity
Canada's Physical Activity Guidelines recommend that children and youth aged 5 to 17 get at least 60 minutes of moderate-to-vigorous physical activity (MVPA) per day; and adults get 150 minutes of physical activity per week.20 In fact, about 94% of Canadian children and youth do not meet minimum physical activity guidelines.21 Furthermore, about 85% of Canadian adults do not meet the minimum guidelines. Physical activity includes but is not limited to sports and recreation. Using active transportation to get to work as well as being active at work is an alternative form of MVPA and can also lead to improved health.
For most Canadians, the average day is spent on passive activities such as TV viewing, computer and game-console use, workplace sitting, and time spent in automobiles. Moreover, the sprawling suburban communities, in which many live, do not encourage physical activity.
Emerging research suggests that prolonged sitting time is associated with an increased health risk.22 These findings mean that one can meet the minimum physical activity guidelines and still not engage in a healthy lifestyle. Spending a few hours a week at the gym or otherwise engaged in moderate or vigorous activity doesn't seem to significantly offset the risk. Hence too much sitting is a risk distinct from too little exercise.
While further research is required to identify which methods of exercise promotions work best for individuals,23 it is clear that supportive environments and infrastructures are essential for Canadians to make physical activity part of their daily lives. CMA's policies about the Built Environment and Active Transportation support the role of the environment on our physical activity patterns.
How we can promote physical activity and healthy eating
A sedentary lifestyle is a cue for physician advice.24 Physical activity is a vital sign that may require as much attention as other traditional vital signs25 - weight, blood pressure, or smoking history. Physicians are eager to initiate these conversations, especially with patients living with chronic diseases. A message must be repeated many times in order to effect a change in lifestyle. Physicians can reiterate the medical importance of physical activity and healthy eating by reinforcing this message during each office visit, and writing the recommendation on a prescription pad.26 For instance, in British Columbia, physicians are prescribing exercise on specially-designed pads, distributing free pedometers, and hosting free walking events for their patients and the public. In the Edmonton area, Primary Care Networks are prescribing free access passes or a free month of access at local municipal recreation facilities. And in Nova Scotia, physicians have been running a free provincial running program for over 10 years that benefits thousands of kids in elementary school.
Nonetheless these clinical interventions alone cannot shape healthier food consumption patterns and lifestyle choices. An obvious starting point to develop a comprehensive policy is to understand the interplay between individual and environmental determinants that influence our behaviours. In this regard, CMA has developed policies on Active Transportation and the Built Environment and Health which recognize the role of neighborhood design and alternative modes for transportation for an active lifestyle. This approach is also at the heart of the Integrated Pan-Canadian Healthy Living Strategy (PCHLS)27, approved in 2005 by all levels of government. CMA commends the efforts put in the PCHLS to prioritize healthy eating and physical activity.
What we recommend
CMA looks forward to working with others in making options for physical activity and healthy eating more available and accessible to all Canadians. The following recommendations highlight the potential contributions of the following sectors: health professionals, all levels of government, communities, workplaces, schools, the food industry and individuals and families.
CMA encourages physicians to promote healthy eating and physical activity inside and outside their office.
Physicians are lifestyle change agents and remain the preferred source of information about health for many people. Physicians, who are committed to physical activity, are role models whose advice on healthy living is more likely to be adopted.28 CMA encourages physicians to address any work-imposed limitations - such as the lack of time, motivation, or tiredness - that could also influence their own exercise and eating habits.
In clinical practice, physicians can help patients start or maintain a healthy lifestyle by:
* assessing nutrition and physical activity as part of routine assessments;
* determining the factors that influence individual patient's nutrition and physical activity levels;
* assessing patient's readiness to change and tailoring interventions and support to their current situation;
* providing an exercise prescription to encourage physical activity to maintain or improve health status, and
* working in inter-professional teams to provide patient education with other health care providers such as dieticians.
Medical students and residents, while reporting a high level of importance for exercise prescription concede a low level of expertise in this area upon graduation.29,30,31 As knowledge develops, physicians and other health professionals should be kept updated and encouraged to incorporate the most effective interventions into their practices. The CMA encourages the development of continuing medical education courses on issues related to physical activity and healthy eating.
Within the healthy living approach, there are multiple opportunities to extend the role of physicians into the community as observed in Nova Scotia, British Columbia and Edmonton area. Physicians can establish strong community norms for a healthy lifestyle by:
* establishing and reinforcing healthy food policies in hospital cafeterias or at health-related meetings and conferences
* using, facilitating and advocating for the use of active transportation in their communities
* working within the community to ensure that recreation centres and other facilities are available and patients can be referred to the services most appropriate to their needs
Federal, Provincial, and Territorial Governments
CMA calls on federal, provincial, territorial and municipal governments to commit to a long-term, well-funded Canada-wide strategy for healthy living beyond 2015.
In 2005, Canada's federal, provincial, and territorial governments endorsed a 10-year Healthy Living Strategy Framework, whose initial priorities included the promotion of healthy eating and physical activity. The national strategy addressed information and support for Canadians to help them make healthy choices; support for physicians and other health professionals in counselling patients on healthy weight and in treating existing obesity; community infrastructures that make healthy living easier; and public policies that encourage healthy eating and physical activity. The federal and provincial / territorial governments have undertaken a number of activities in the intervening years to promote physical activity and healthy eating but much remains to be done.
CMA believes that all levels of governments have a continuous obligation to provide public guidance on healthy eating and to promulgate policies, standards, regulations and legislations that support the availability and accessibility of healthy and affordable food and beverage choices.
CMA calls on governments to improve access to nutritious food at affordable prices for all Canadians.
The price of milk, fresh produce and other healthy foods can vary greatly across Canada. In many remote areas, they are often more expensive than processed, nutrition-poor foods because of high transportation costs. Governments should implement effective programs to offset the impact of transportation costs on food prices in northern and remote communities. Even in urban areas, nutritious food may be unaffordable for people on low incomes. School meal programs, social assistance rates that take into account the cost of purchasing healthy food, access to urban farmers' markets can help to ensure that all Canadians have access to healthy foods at a reasonable price.
CMA calls on governments to ban marketing of foods and beverages high in salt, sugars and trans fats to those 13 years of age and younger.
The typical Canadian child may be exposed to as many as 40,000 advertisements for food a year.32 This does not include point-of-sale promotions, such as displays of candy bars at convenience-store counters. CMA's policy on marketing of unhealthy foods and beverages to children and youth calls for a ban on marketing of foods and beverages high in salt, sugars and trans fats to those 13 years of age and younger.
CMA calls on governments to set rigorous standards for front of package food labeling and for the advertising of health claims for food.
Brand-specific advertising is a less than optimal way to provide health information to consumers, who should be encouraged to seek out objective information sources for answers to their questions about physical activity and healthy eating. To improve the quality of information received through commercial channels, the CMA recommends that health claims made for foods be strictly regulated to ensure that they are based on the best available scientific evidence and that they are accurately communicated to consumers. Food advertisements should be pre-cleared before airing in the media, and the provisions against deceptive advertising in the Food and Drug Act should be strengthened.
CMA recommends that governments at all levels invest in evidence-based research on healthy eating and physical activity and share the results of this research with all Canadians.
CMA encourages all levels of governments to continue to fund and support research for healthy lifestyles. There is a clear need to invest in research to strengthen the evidence base about physical activity and healthy eating, particularly on:
best measures for assessing overweight and obesity;
the effectiveness of weight management and treatment programs; and
the effect of policy interventions on healthy eating and physical activity on rates of obesity and obesity-related disease.
CMA encourages governments to continue to work with the food industry to improve the food environment in Canada.
The partnership and collaboration of food manufacturers is needed to help Canadians make healthier food choices. The food industry can work with governments to:
reduce the salt, sugar, saturated fat, trans fat and calorie content of processed foods and pre-prepared meals;
provide information about the calorie and nutrition content on restaurant menus;
restrict advertising and in-store promotion of high-sugar, high-salt, high-fat foods, particularly those aimed at children;
provide user-friendly consumer information about their products, including and accurate health and advertising claims;
improve the nutrition fact table to make it more user friendly and increase the amount of information for example, by identifying the amount of free sugars.
CMA calls on municipal governments to create environments that encourage healthy and active living and on federal, provincial and territorial governments to support them in this endeavour.
Communities have an important role to play to promote healthy behaviours for children, youth, and adults. They shape how many Canadians decide to live, work and play in their daily life. Through mixed-use land planning and building design, communities can create walking-friendly environments, and reduce the time people spend in cars. To achieve this, communities should consider:
developing and maintaining a community-wide network of walking and cycling paths;
zoning communities in such a way that amenities are within walking distance of homes; and
revising building codes to make stairs accessible, pleasant and safe, so that people have an alternative to taking the elevator.
Canadians are considerably more physically active in the summer than in the winter and this could have an impact on obesity trends.33 Communities could improve pathways to healthy lifestyles year-round by improving access to indoor sport and recreation facilities, especially during winter. Where possible, communities should consider partnering with schools to share the use of gymnasiums, playgrounds, fields, courts, and tracks with the public after school hours and on weekends. In doing so, communities are ensuring the best use of time and resources, but also sharing liability for the development, operation, and maintenance of the facilities.
Community food security can happen if local residents have equal access to safe, affordable and nutritious food. Communities have a role to play in advocating for healthier food options in schools and workplaces, encouraging community kitchens to teach cooking skills, and supporting local agriculture and farmers markets. This, in turn, would encourage individuals to eat more healthy foods.
CMA encourages employers to actively promote the health of their employees by providing opportunities for physical activity, and healthy food choices in cafeterias.
Prolonged, unbroken time spent sitting in front of a screen is very common in the workplace. In addition, four out of five commuters sit daily in their private vehicles to go to work.34 As Canadians spend most of their adult life at work, it is important to reduce workplace sitting. CMA encourages employers, especially in sedentary occupational groups, to increase opportunities for physical activity. For example, employers can promote healthy behaviours by:
Building on-site fitness facilities or entering into agreements with off-site fitness centres to provide programs for their employees
Providing showers, bike racks and other amenities for employees for those who want to commute to work on foot or by bike.
Healthier food options in cafeteria and vending machines can promote and encourage healthy eating by employees.
Schools, where children spend most of their time outside of home, present an excellent opportunity to instil healthy behaviours at an early age. They could, for example, provide comprehensive nutrition education, serve nutritious food in their cafeterias and promote physical activity by providing formal instruction and informal recreation time. Schools can provide the most effective and efficient way to reach not only the children themselves, but their parents, teachers, and other community members.35
CMA encourages school boards to provide at least 60 minutes of active daily physical education for all primary and secondary grades.
Only 26% of Canadian schools reported that they had implemented daily physical education classes for their students.36 There is some evidence that school-based physical activity can increase physical activity levels and reduce time spent watching television at home. 37 For instance, schools can promote physical activity through unstructured out-of-home play, structured sports, or active transportation (e.g. walking to school). Children who are physically active and spend less time watching television after school are less likely to become overweight before age 12.38
CMA recommends that schools provide access to attractive, affordable, healthy food choices, provide nutrition education, and initiate programs aimed at encouraging healthy food consumption and skills to prepare meals from scratch.
CMA calls for restrictions on the sale of high-calorie, high fats, sugars or salts foods/drinks in recreational facilities frequented by young people.
Fast food restaurants and convenience stores can be an important influence on children's eating habits and food choices.39 Children attending schools within a short distance of fast food restaurants eat fewer fruits and vegetable servings, and drink more soft drinks than others who did not have similar establishments within proximity.40 To encourage effective school-based nutrition interventions, it is therefore important to educate students about the nutrition value of foods, healthy food choices, and provide healthy canteens or cafeterias.
Individuals and families
CMA recommends that all Canadians work toward achieving and maintaining health by:
educating themselves about their dietary needs and about the caloric and nutrition content of foods; and
engaging in physical activity, with the goal of at least 60 minutes of moderate activity per day for children and youth, and 150 minutes per week for adults.
Ultimately, healthy eating and physical activity require that individuals take action to make healthy choices in their lives. To inform these choices, Canadians should be supported with appropriate resource materials with consistent information about healthy eating and physical activity. For instance, many young children do not choose what they consume; their parents buy and prepare the food for them. Research suggests that mothers and children appear to have divergent attitudes towards food and mealtimes.41 In this regard, it is important for parents to be well-informed and able to explain the tangible benefits of foods and their nutritional components to their children before they reach adulthood.
What we conclude
Healthy behaviours are easier to maintain through life if acquired in childhood and encouraged by the family. Therefore Canadian families should be supported in efforts to ensure that both children and adults eat nutritiously and exercise daily. We believe there is a role for everyone in promoting healthy behaviours - including health professionals, individuals, families, schools, workplaces, communities, the food industry and all levels of governments.
Popular approaches seek to provide individuals with information and options about healthy lifestyles choices. However, individual choice is not sufficient to ensure healthy behaviours.
Many barriers to the adoption of healthy behaviours and lifestyle choices can be met through a targeted population health approach, and evidence-based policy and regulatory controls. A comprehensive change in culture and mindset, political endorsement and multifaceted strategies are needed to promote and facilitate change to improve the dietary practices and physical activity levels of Canadians.

IMPROVING EFFICIENCY IN THE CANADIAN HEALTH CARE SYSTEM
Achieving value in health care systems is an important objective for all nations.1 Health care systems in Canada and elsewhere are examining ways to address inefficiencies to make the system more cost-effective and sustainable while improving the quality, continuity, and comprehensiveness of care. This policy statement puts forth recommendations for system sustainability and improving quality of care. All system stakeholders including providers, funders and patients bear responsibility to ensure the health care system is as efficient as possible. Physician input is a necessary condition for meaningful system improvement and innovation.
Health care systems in Canada and elsewhere are examining ways to address inefficiencies to make the system more cost-effective and sustainable while improving the quality, continuity, and comprehensiveness of care. The concept of efficiency in health care has two applications. The most common is technical efficiency, which is defined as producing maximum output for a given level of inputs, or minimizing input for a given level of output.2 The difference between actual output and the maximum achievable output may be attributed to inefficiency within the system.
The second is called allocative efficiency, which refers to optimizing resource allocation to produce maximum outputs that fulfill societal demands. Canadian research suggests that increasing technical and allocative efficiency rather than increasing spending could solve some of the current challenges regarding health care quality and sustainability. Based on a macro system-level approach to estimating efficiency among its member countries, the Organization for Economic Cooperation and Development (OECD) has estimated that all of its member countries could achieve better value from their health care spending-Canada could save 2.5% of Gross Domestic Product in public spending by 2017 if it were to become as efficient as the most efficient OECD countries.3

The various inefficiencies in the Canadian health care system may be categorized and visualized using the conceptual framework developed by Bentley et al in 2008 for the U.S. health care system 4 (see Figure 1). In Canada, no such framework exists.
The framework of Bentley et al contains three main categories of inefficiencies - clinical, operational, and administrative. Clinical inefficiencies relate to practice variation challenges including, the provision of inappropriate care. Operational inefficiencies include duplication of health care services, inefficient processes, overly expensive inputs, and errors in data collection and processing. Administrative inefficiencies may be generally thought of as excess transaction costs associated with claims payment and excess costs of administration and management over and above what is required to deliver front-line health care.

2.1 Clinical Inefficiencies
Clinical waste and inefficiencies refer to services that provide marginal or no health benefit compared with less costly alternatives. This may include practice variation and the provision of inappropriate and cost-ineffective care, or the underuse of more appropriate care. There is overlap between clinical inefficiencies (e.g., providing the wrong service) with operational inefficiencies (the inefficient production of services).
The chief contributor to clinical inefficiencies or waste in the health care field is practice variation-the reduction of unwarranted care variation is the foundation of the quality movement. John Wennberg and colleagues have pioneered the main body of work in this area through their studies on small area variation in care delivery.5 Over the last quarter century, technical studies on clinical practice guidelines (CPGs) have been developed in increasing numbers to address issues of appropriateness of care and care variation.
CPGs are defined as "systematically developed statements to assist practitioner and patient decisions about appropriate health care for specific clinical circumstances".6 CPGs should contribute to better health, enhance the quality of care by reducing practice variation, and contribute to better value and lower costs by encouraging more appropriate use of resources by care providers.7 Although there has been no systematic approach in Canada to developing and disseminating CPGs, or to ensuring the quality of the CPGs produced, various organizations have developed initiatives to tackle this issue.8
Since the early 1990s, the Canadian Medical Association (CMA) has developed and maintained a CPG Infobase, which contains roughly 1,200 guidelines.9 The uptake of CPGs is a crucial component and insufficient resources are applied to necessary clinical practice change processes. Moreover, CPGs should be distillable to actionable points-of-care recommendations suited to the intended end user (e.g., family physicians).
In January 2012, the Council of the Federation (CoF) established the Health Care Innovation Working Group, which comprises all provincial and territorial health ministers, to determine practical and innovative ways to increase the value and effectiveness of care.10 The group's CPG recommendations focused on cardiovascular disease and diabetes - two of the most prevalent and highest-costing chronic diseases in Canada (see Appendix A for list of CPGs). In accordance with the CoF, the CMA recommends:
1. Developing chronic disease management and other supportive strategies for vulnerable patients at risk of frequent readmission to the acute care system.
2. Integrating clinical practice guidelines with electronic medical records.
3. Implementing a pan-Canadian clinical practice guidelines strategy.
4. Using evidence-informed clinical practice guidelines to evaluate patient outcomes, appropriateness, and cost-effectiveness.
5. Developing deployment strategies to ensure maximum use of clinical practice guidelines by physicians.
Clinical practice guidelines need regular updating as new evidence emerges. Therefore, a Pan-Canadian strategy should include a system of regular review and updating using development methods that would exclude the possibility of industry bias. Canada's physicians are taking a leading role on this matter through such initiatives as Choosing Wisely Canada (see below).
There is an increasing trend in health care utilization in areas such as medical procedures, drugs, and physician services.11 Questions remain about whether or not people are receiving care that is appropriate and based on the best available scientific information.12 Inappropriate care, such as the hospitalization of patients who need community-based services or prescribing antibiotics for upper respiratory infections that are likely viral in origin, is another source of clinical inefficiency, using scarce resources for marginal or no health benefit.
The CMA recently defined appropriate care as the right care, provided by the right provider, to the right patient, in the right venue, at the right time:
* "right care" is based on evidence for effectiveness and efficacy in the clinical literature, and not only implies appropriateness of use, but inappropriateness of failure to use;
* "right provider" is based on ensuring the provider's scope of practice adequately meets but does not far exceed the skills and knowledge to deliver the care;
* "right patient" acknowledges that care choices must be matched to individual patient characteristics and preferences;
* "right venue" emphasizes that some settings are better suited in terms of safety and efficiency to delivering a specific type of care than others;
* "right time" indicates care is delivered in a timely manner consistent with agreed upon bench marks.
As a corollary to this definition, if all five components are present, high quality care has been delivered with the optimal use of resources, that is, waste has been eliminated and the best value has been obtained.
Appropriateness is primarily determined by analyses of the evidence of clinical effectiveness, safety, and other health system impacts.13 The practical application of appropriateness is made when these analyses are qualified by (a) clinician judgment, particularly in atypical circumstances14 and (b) societal and ethical principles and values, including patient preferences.
There are a number of perverse incentives that can contribute to the delivery of inappropriate care across the system. These exist at the system level (e.g., patients staying in hospitals longer than needed due to the lack of community services), as well as at the individual encounter level (changes in fee codes for insured medical services such as new consult fees to see a patient every six months). Physicians and payers such as governments need to work together to eliminate perverse incentives based on available medical evidence. Physician incentives should align with system needs. The challenge is getting governments, health authorities and provincial and territorial medical associations, and individual providers agreeing on system goals and objectives.
In the U.S., an innovative appropriateness initiative called Choosing Wisely was established in 2011 with the goal of improving care quality and reducing harm to patients by avoiding unnecessary interventions, with the added benefit of possible cost reductions.15 The initiative challenged specialty societies to identify five clinical activities in their field that are generally of little value or are potentially harmful to patients.16
In Canada, CMA's 2013 General Council called for the formation of a collaborative working group to develop specialty-specific lists of clinical tests/interventions and procedures for which benefits have generally not been shown to exceed the risks. Choosing Wisely Canada was launched on April 2, 2014 with the release of eight lists produced by nine specialty societies (one list was released jointly by the CMA's Forum on General and Family Practice Issues (GP Forum) and the College of Family Physicians of Canada (CFPC)). Twelve additional medical specialty societies released lists in October 2014. The Choosing Wisely Canada campaign is endorsed and supported by over 35 national specialty societies representing a broad spectrum of physicians, as well as by all provincial medical associations, patient organizations, accrediting bodies and others (Website: www.choosingwiselycanada.org). Choosing Wisely Canada aims to promote physician-patient communication about unproductive care and conserve resources by eliminating unneeded activities. This initiative also serves as an example of the role of public education campaigns to help improve appropriate care.
The development of a Canadian version of the Choosing Wisely initiative assists in operationalizing the Institute for Healthcare Improvement's (IHI) Triple Aim concept of better care, better health, better value. Specific benefits include:
* Improving accountability by providing transparent, evidence-informed care;
* Facilitating patients to make the right care decisions;
* Enhancing physician-patient relationships: improve communication and decision-making between patients and their physician; and
* Reducing clinical inefficiencies.
The ultimate objective and impetus for adopting a Choosing Wisely initiative must be to improve patient outcomes. Cost savings to the system should occur as a byproduct. Physicians are in the best position to identify which medical services are unnecessary.
Both patients and providers need to be aware of the costs associated with each treatment option, recognizing there is a balance to strike between cost and value. To facilitate this process, the CMA recommends:
6. Making available data on the cost and cost-effectiveness of treatment options at the point of care.
7. Collecting information to evaluate cost-effective care.
8. Posting costs generated by requests for diagnostic and laboratory tests in electronic medical records.
Evaluation should take place to ensure the posting of costs is targeted to areas where it will be most effective.
2.2 Operational inefficiencies
Examples of operational waste include: undertaking tests or procedures more frequently than clinically necessary (e.g., duplication of tests); unnecessary time spent waiting for medical services or time wasted from processes that add little value; using brand drugs for patients who get equal benefit from generics; and health and cost consequences of medical errors or the use of defective medical devices.
These system inefficiencies can amount to very significant costs to the health care system, patients and the economy. For instance, lengthy waits can have serious health consequences for patient outcomes and result in the substitution of additional health care services while waiting (e.g., use of pain medication). A 2008 study calculated the economic impact of excessive wait times for five procedures (hip and knee replacement surgery, MRIs, CABG surgery and cataract surgery) in all 10 provinces. It found that, in addition to the obvious emotional, physical and financial toll endured by patients and their families, lengthy waits for these medical treatments cost Canada's economy an estimated $14.8 billion overall in 2007 in reduced economic activity by patients ($16.9 billion in 2014 dollars). This included a $4.4 billion reduction in federal and provincial government revenues.17
Notwithstanding a shortage in health care infrastructure, there is general consensus that not all hospital infrastructure is used to its fullest capacity, contributing to lengthy wait times for many patients. This can include excessive turnover time between cases or limited operating room hours that can result in the last patient of the day being unable to receive their surgery at great cost to the patient and their family. In many instances, urban hospitals must cancel surgeries due to overbooked operating room time when in smaller and rural communities, operating rooms are not fully utilized. Strategies should be explored to enable greater use of health infrastructure resources in smaller community hospitals that will serve to enhance timely access to care for patients. This would also ensure that staff had a level of activity that would maintain their skills.
There has been significant uptake of operations research and quality improvement processes to help eliminate operational waste and address unnecessary waiting by patients. To this end, CMA will continue to work with its partners in the Wait Time Alliance to identify strategies to improve timely access to care for patients across the continuum. The CMA will also study the potential health applications of the Theory of Constraints within the Canadian health care system.18
There can also be system-wide inefficiencies in the various health systems operating in the country and in terms of how health systems interact with other systems such as economic and social support systems (e.g., lack of services to address homelessness). Changes in one component of the health care system can negatively affect the efficiency in another component. For instance, cuts made to home care services can lead to a rise in the number of alternate-level-of care (ALC) patients in hospitals, increased wait times in emergency departments, and elective surgery cancelations. A more recent source of system inefficiency has been occurring due to the piecemeal adoption of electronic medical records and information systems (EMR) throughout the country. The multitude of systems adopted by different segments of the health care system has resulted in problems with system inter-operability that often exacerbate administrative and clinical inefficiencies such as preventing the electronic attachment of test results leading to the reordering of tests.
The Canadian Institute for Health Information (CIHI) developed a model to measure and evaluate "health system efficiency" within Canada. It measures the average efficiency of health systems in Canada's health regions and the factors that help explain variations in estimates of system efficiency (measured as the reduction in potential years of life lost (PYLL) from treatable causes of death). The study found that equitable access to physician care is positively associated with efficiency.19 Unfortunately, over 4 million Canadians still do not have a regular family physician.20
In addition, the CIHI study found that factors related to the social determinants of health can also affect system efficiency (e.g., missed prevention opportunities). Frequently, the health care system is relied on to address preventable health needs that are attributable to the social determinants of health (e.g., injuries or illnesses caused by lack of affordable housing or poverty). Furthermore, these factors can negatively affect the effectiveness of any treatment provided by the health care system.21
Governments and health administrators should focus on improving efficiencies where there is the highest volume of services as new models of efficiency do not always show results in low volume areas.
2.3 Administrative inefficiencies
Health programs can be funded and administered at a variety of levels: local, regional, provincial and federal, as well as through employers. According to CIHI, administration accounted for $6.3 billion, or 3.1%, of health care costs in Canada in 2011-roughly middle of the pack among OECD countries22-but this is only the cost of providing public and private health insurance programs and the costs associated with health departments'operations.11 Generally, differences in the level of health administration can be explained in part by the type of health system and financing used such as whether multiple insurance providers exist or the extent that complex funding and billing procedures are in place.23 1
In terms of other administrative costs, we do not know how Canada has evolved over time in comparison to other sectors of the economy or how we compare internationally with respect to the effectiveness of administration expenditures.1 There have been questions about the expansion and contraction of regional health authorities in Canada over the past two decades. However, Canada does not have a detailed set of health accounts that would permit such analysis. CIHI has recently begun to report the percentage of administrative services expenses (general administration, finances, human resources and communications) as a percentage of total expenses for over 600 hospitals as part of its Canadian Hospital Reporting Project (CHRP).24
One source of administrative waste is the cost of duplicate collection and recording of health information. The health sector has been slow in adopting health information technology to help reduce this form of administrative waste.
Another cause of inefficiency is the increase in administrative burden faced by Canadian physicians and their patients. A major contributor is the rise in requests for physicians to complete third party forms from insurance companies and governments (see Appendix B for a list of examples of federal health programs and related medical forms). Different definitions of concepts are frequently used in these forms, but in many instances they are asking for similar information about the same patient. Physicians are also frequently requested to complete sick notes-the CMA believes such an absence does not require physician confirmation of illness and represents an inefficient use of scarce health care resources.25
The cumulative effect of a physician being requested to complete several forms each day can result in significant administrative burden and take away time that physicians can spend providing direct patient care. Standardizing definitions and wording on third-party forms can save time and reduce administrative errors. Physicians fully support any efforts by the private insurance industry and governments to standardize their medical forms. In addition, consideration should be given to instances where other designated providers can be tasked with completing particular forms. Where suitable, electronic medical records (EMRs) can improve the completion and timely submission of third-party forms to the benefit of patients, providers and third-parties.
To address these administrative inefficiencies, the following actions have been recommended by CMA:
9. Federal and provincial auditors general design and implement a protocol for detailed enumeration of administrative costs within their health care systems, including tracking of these costs over time, and issue an annual public report.
10. CIHI conduct a detailed study of administrative costs of Canadian hospitals and regional health authorities and report the findings.
11. Harmonize and centralize, in electronic and written format, all administrative forms that physicians must fill out on behalf of their patients.
3. Innovating for efficiency
Since the late 1990s, the federal, provincial, and territorial governments, and other granting bodies have provided considerable funding for applied health services research to aid the implementation of pilot projects to improve the quality of care delivered in Canada. However, Canada is frequently criticized for its inability to move beyond pilot projects to full implementation. One often-cited reason is the lack of communication about promising innovations from one jurisdiction to another. Other reasons include regulatory barriers such as funding silos, and pilot project funding for a limited duration to prevent meaningful outcome evaluation. Physician input is a necessary condition for meaningful and sustained system innovation.26
The CMA supports:
12. Developing and testing innovative structures or programs to demonstrate clear evidence of improvement in health care outcomes and fiscal sustainability before wide-spread adoption into the Canadian health delivery system.
13. Developing policy tools that provide criteria for identifying barriers to quality, efficiency and equity in emerging models of health care delivery.
14. Creating a registry of physician-managed health care transformation projects. This registry should outline the challenges and lessons learned associated with each project for those interested in adopting similar projects.
Addressing efficiency challenges in the Canadian health care system can improve the quality, continuity, and comprehensiveness of care, while making the system more cost-effective and sustainable. Many components of the health care inefficiencies set out by Bentley et al are now being considered by governments. Physician input is a necessary condition for meaningful system improvement and innovation. Physicians should practice high quality, evidence-informed health care, and advocate for cost-effective allocation of scarce resources. Canada's physicians are taking a leading role on this matter through such initiatives as Choosing Wisely Canada.
Clinical Practice Guidelines (CPGs) recommended by
The Health Care Innovation Working Group of the Council of the Federation
The group recommended each province and territory work with their health authorities to adopt the following CPGs:
* The C-CHANGE guidelines for cardiovascular disease published by the Canadian Cardiovascular Harmonization of National Guidelines Endeavour (C-CHANGE) to reduce guideline variations and confusion among care providers.
* Harmonized guidelines for diagnosis, which include:
o Laboratory testing (e.g., urine analysis, ECGs)
o Risk stratification strategies (e.g., family history, lifestyle choices, and diabetic patients).
* Harmonized guidelines for treatment, which include:
o Establishing treatment targets (e.g., limiting alcohol consumption, healthy body weight, glycemic or glucose targets)
o Health behavior interventions (e.g., balanced heart healthy diet, limiting salt intake, smoking cessation)
o Pharmacological therapy (e.g., assessment of drug and drug interactions, co-morbidities).
