The major diseases affecting the quality and quantity of life of Canadians, which include obesity, diabetes, coronary artery disease, depression and cancer, are all linked to physical inactivity. In Canada, 69% of women and 68% of men in Canada are considered physically inactive.(1) The cost of this inactivity and obesity was estimated at $4.3 billion in 2001.(2) A 10% increase in physical activity could potentially reduce direct health care expenditures by $150 million a year. This does not include indirect costs such as lost productivity due to illness, premature death or a range of other factors, including mental illness and poor quality of life.(3)
Thus far, efforts to increase physical activity by changing the behaviour of individuals have had limited success. One reason is that many people have difficulty sustaining behaviours that involve additional time commitments. That is one reason for the increasing emphasis being placed on active transportation, which is any human-powered form of transportation, such as walking and cycling.
Walking and cycling can be efficient alternatives to automobile travel. Cycling is usually the fastest mode of travel door to door for distances under five km, and for up to 10 km in city cores. Walking is simpler and nearly as fast for distances up to two km. When travel times are similar for active and motorized transportation, physical activity is gained with no net time lost, and at much lower cost. The cost of operating a motor vehicle is typically $10,000 per year,(4) while operating costs for a bicycle are much lower.
Communities that have sidewalks, enjoyable scenery, street lights and nearby stores have improved levels of active transportation and physical activity. However, in recent decades communities have often been designed around the automobile. Street design, parking space, sidewalks and distance to retail destinations have all been planned assuming motorized transportation, and this often makes it difficult to move around communities by walking or cycling.
Although individual decision-making remains important in any strategy for increasing active transportation, there is an essential role for communities and governments to play. Major improvements in the health of Canadians in the past 200 years have been due to improved sanitation, access to clean water and injury prevention. The role of individual decision-making in effecting these changes is dwarfed by the impact of the public health measures and infrastructure involved. Just as potable tap water is a health issue, so are decisions about land use, transportation policy and infrastructure.
Community design is a major determinant of whether people use active transportation, whether they are physically active and whether they are obese. Canadians need communities that make it easy to be physically active in their daily living.
Communities can create an environment in which the physically active choice is the easy choice. They can do this via sidewalks, trails, bicycle lanes and bicycle paths, and by providing pedestrian-friendly intersections, parks and green spaces, and safe bicycle parking spaces. They can also arrange zoning so that retail destinations are within walking or cycling distance of residential areas. This process also includes dedicating a sufficient portion of their street maintenance budget (including snow clearing) to maintaining active transportation routes as well as routes for motorized vehicles. It may include redesigning intersections, giving up vehicle lanes or parking spaces, or increasing the price of parking.
Additional benefits to designing communities for pedestrians and cyclists.
* a stronger sense of community with greater civic involvement by citizens
* increased property values and retail activity
* less noise pollution
* lower crime rates
* less smog and other air pollution
* less greenhouse gas production
* decreased risk of injury to pedestrians and cyclists
* decreased costs of roadway and parking construction.
A role for everyone
Other sectors can support communities in making active transportation choices easy choices:
* Businesses can create a work environment friendly to active transportation, including a corporate culture friendly to physical activity. They can incorporate active transportation planning into building design and create an environment friendly to physical activity. These steps could include making bicycle parking, showers and lockers available, and providing stairs that are pleasant and easier to access than elevators. They can also incorporate a culture of physical activity in decisions about where and how to hold meetings, and what people are allowed to wear to work.
* School boards can develop policies to promote active transportation to and from school. These include building and maintaining secure bicycle parking, ensuring safe walking routes within communities, and assisting parents in walking their children to school.
* Citizens can use active transportation themselves and treat with respect those who are already making active transportation choices. They can also lobby governments to make their community safer and easier places for cycling and walking.
* Physicians can encourage patients to use active transportation as a way to boost their physical activity levels and improving their health. They can also lead by example and use active transportation themselves.
The CMA 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.
The CMA urges governments to:
* Commit to long-term plans for active transportation networks that are in keeping with these goals and that include specific benchmarks to measure progress.
* Require that active transportation be part of all infrastructure renewal projects, with investment in active transportation vs. motorized transportation in proportion to targeted active transportation use. (Some cities have achieved active transportation rates of up to 15%.)
* Develop an awareness campaign to help Canadians to recognize the value of active transportation in their communities.
* Require public health impact assessments for all land-use and transportation decisions, including the impact on the chemical environment and on physical activity.
* Assess the impact that changes in the "built" environment can have on public health, and which interventions are most safe and effective.

With the advent of technology allowing for the extension of life, and as a result of the increasing importance of personal autonomy, decisional capacity, and informed consent and the growing awareness of issues related to quality of life and dying, Canadians have become increasingly interested in expressing their wishes regarding their health care and having more input into decisions about their care should they become incapable. Advance care planning (ACP) can help patients to achieve these goals.
The CMA supports development of a strategy for ACP1 in all provinces and territories. ACP leads to better concordance between patients' wishes and treatments provided,2,3 decreased anxiety for families,4 decreased moral distress for health care providers,5 decreased hospitalization rates of nursing home residents3 and fewer unnecessary medical treatments.3,6,7
ACP is at the intersection of the provision of health care, ethical values and legal rights and duties. In particular, it involves the acknowledgement of essential aspects of autonomy, informed consent, and respect of patients' care wishes now and in the future, and their intentions if they become incapable.8,9
The balancing of the need to obtain informed consent for a treatment option in the present with the need to respect health care preferences that were stated in the past has been addressed using various clinical, legal and institutional approaches across Canadian jurisdictions."
Physicians10 can play a significant role in ACP throughout the course of the patient-physician relationship, including in the pediatric setting. At any time, outcomes of the planning process can be documented and/or the patient can appoint a substitute decision-maker in writing. These documents can be identified as advance directives, personal directives or powers of attorney for personal care11 (hereinafter all will be referred to as advance directives). An advance directive does not remove the need for a physician to obtain consent before providing a treatment to a patient, except in an emergency. As stated in the Canadian Medical Protective Association's consent guide: "[U]nder medical emergency situations, treatments should be limited to those necessary to prevent prolonged suffering or to deal with imminent threats to life, limb or health. Even when unable to communicate in medical emergency situations, the known wishes of the patient must be respected."12
While much of the focus of ACP is on making care decisions and nominating proxy decision-makers in case the patient becomes incapable of making decisions in the future, ACP has much more utility. ACP conversations13 can assist patients in determining treatment trajectories and making decisions about the intensity level of interventions in their current care. Providers can have discussions with patients and their families about proposed treatments in the context of the patient's communicated goals and wishes. The process of ACP also helps patients and their families to become familiar with the language and processes used to make cooperative health care decisions.
SCOPE OF POLICY
This policy aims to provide guidance on key considerations pertinent to ACP in a way that is consistent with a physician's ethical, professional and legal obligations. This is a complex subject: physicians should be aware of the legislation in the jurisdiction in which they practise, the standards and expectations specified by their respective regulatory authority, as well as the policies and procedures of the setting(s) in which they practise (e.g., regional health authority, hospital).
1. ACP is a process of (a) respecting patients' wishes through reflection and communication, (b) planning for when the patient cannot make health care decisions and (c) discussion with friends, family and professionals; (d) it may result in a written document.5 It informs the substitute decision-maker and provides information for the clinician to consider in the provision of care within the bounds of the law.
2. Although often associated with the end of life, ACP represents the expression of a patient's wishes for any future health care when the patient is incapable. It expresses the patient's values and beliefs regarding current care decisions and provides information that can inform any decisions that must be made during an emergency when the patient's consent cannot be obtained. For these reasons, ACP should occur throughout a person's lifetime.
3. Respect for patients' dignity and autonomy is a cornerstone of the therapeutic physician-patient relationship. Patients' right to autonomous decision-making has become embedded in ethical frameworks, consent legislation and case law.14 Respect for the wishes of an incapable patient constitutes a preservation of autonomy and promotes trust between the physician and patient.15
4. The way in which the act of obtaining consent is weighed against the patient's stated wishes as outlined during the ACP process varies according to the jurisdiction in which the patient and physician are located.
1. Given the practical, ethical and legal complexities of ACP, physicians, medical learners should be supported in becoming familiar with ACP and comfortable in engaging in the process with their patients. To this end, CMA supports the development of training in ACP and efforts to make it available to all physicians and medical learners.16 For practising physicians and residents, many resources are available, for example:
a. Advance Care Planning in Canada: A National Framework
b. Facilitating Advance Care Planning: An Interprofessional Educational Program
c. Information from the Health Law Institute of Dalhousie University on the regulatory policies and legislation of individual provinces and territories
d. A comprehensive collection of Canadian resources compiled by the Speak Up campaign of the Advance Care Planning in Canada initiative
e. Pallium Canada's Learning Essential Approaches to Palliative Care module on ACP
In the case of medical students, the CMA supports the position of the Canadian Federation of Medical Students that end-of-life training is an essential facet of undergraduate medical education.
2. The issue of the supervision of medical learners practising ACP should be clarified, as considerable ambiguity currently exists.17 Medical learners would benefit from unified national guidelines concerning the nature of their participation in ACP, especially regarding end-of-life care. In the case of medical students, the CMA agrees with the recommendation of the Canadian Federation of Medical Students that supervision be mandatory during conversations about end-of-life care.
3. The CMA calls for more research on the outcomes associated with the provision of ACP training to physicians and medical learners.
4. The CMA recommends that governments and institutions promote information and education on ACP to patients and their substitute decision-makers.
PROFESSIONAL AND LEGAL RESPONSIBILITY
1. While respecting patients' values, all physicians are expected to encourage their patients to engage in ACP with them. ACP is not a one-time event. The nature of the conversation between the physician and the patient and the regularity with which they discuss the subject will depend on the patient's health status. Family physicians and physicians have ongoing care relationships with chronically ill patients are particularly well placed to have regular discussions with their patients about their beliefs, values and wishes. An effective exchange of information between family physicians (and other physicians who work in the community with outpatients) and acute or tertiary care physicians would assist in ensuring patient's wishes are considered.
2. ACP, in particular advance directives, are at the intersection of medicine and the law. Physicians should recognize this and ask patients whether they have an advance directive or have done any ACP.
3. There is wide variation across jurisdictions in terms of the requirements and procedures for ACP; therefore, physicians should inform themselves about any relevant legislation and the scope of the requirement to obtain consent within that jurisdiction when carrying out ACP.
1. The CMA supports institutional processes that recognize and support ACP. Support for ACP includes developing a consistent process for the exchange of information about patients' wishes and advance directives among health care providers, as patients traverse sectors and locations of care. Patients with a written advance directive must be identified and the advance directive integrated fully within the patient's records18 so that it is available across the institution (and ideally the health care system). The CMA advocates for the inclusion of advance care directive functionality as a conformance and usability requirement for electronic medical record vendors.19 Provinces and territories should be encouraged to establish robust organizational processes and resources for patients in all locations of care and strong province- or territory-wide policy, such as in Alberta.20
2. Institutions and other organizations should encourage health care providers to ask patients to bring their advance directive to appointments at the same time they ask them to bring a list of their medications or other medical information.
3. The CMA supports institutional/organizational audits of structures, processes and outcomes related to ACP as an important step in improving the quality and frequency of ACP activities.
ROLE FOR GOVERNMENTS
1. The CMA supports infrastructures enabling ACP, including funding that will support ACP and other end-of-life discussions.
2. The CMA promotes the incorporation of ACP into future federal and provincial/territorial senior strategies and dementia and/or frailty strategies.
3. The CMA supports the development of ACP metrics and their future inclusion in Accreditation Canada standards.
Advance care planning (ACP)
Advance care planning is a term used to describe a process of reflection, communication, conversation and planning by a capable individual with family, friends and professionals about their beliefs, values and wishes for a time when they no longer have the mental capacity to make decisions about their health care. ACP can also involve the naming of a substitute decision-maker.8
The legislated term "advance directive" has different names, definitions and legal authority across the country. For example, in British Columbia an advance directive is a written legal document that provides a mechanism for capable patients to give directions about their future health care once they are no longer capable. 21 As such, in BC an advance directive may, under certain circumstances, be considered "equivalent to consent to treatment and may be acted upon directly by a health care provider without consultation with an SDM [substitute decision-maker]." 8 In Alberta it is called a personal directive. In Ontario, "advance directive" is a generic non-legal term and refers to communications that may be oral, written or in other forms.8
In Quebec, advance care directives are legally binding, as set out in the Act respecting end-of-life care, which recognizes "the primacy of freely and clearly expressed wishes with respect to care. . ."22
Current legislation does not allow for medical assistance in dying to be requested by an advance directive.23 The CMA acknowledges that considerable public, expert and legal debate exists around the issue.
To obtain informed consent, physicians must provide adequate information to the patient or capable decision-maker about the proposed procedure or treatment; the anticipated outcome; the potential risks, benefits and complications; and reasonable available alternatives, including not having the treatment; and they must answer questions posed by the patient. Consent is only informed if there is disclosure of matters that a reasonable person in the same circumstances would want to know.24 Consent must be given voluntarily, must not be obtained through misrepresentation or fraud, must relate to the treatment and must be informed.
Substitute decision-maker (SDM or agent or proxy)
A substitute decision-maker is a capable person who will make health care decisions on behalf of an incapable individual. In all jurisdictions the health care provider must take reasonable steps to become aware of whether or not there is a substitute decision-maker before providing health treatment to an incapable patient. Legally there are implementation differences across the country. For example, in BC a substitute decision-maker is appointed through a representation agreement, in Alberta through a personal directive and in Ontario through a power of attorney for personal care.

Antimicrobials (which include antibiotics) are a precious public resource and an essential tool for fighting infections in both humans and animals. Their importance to human medical, nutritional and economic security cannot be understated. Yet globally, antimicrobials are losing their effectiveness more quickly than new such drugs, treatments and therapies are being identified and introduced to market.1 Over time, this dynamic has eroded the human antimicrobial arsenal, placing the lives and futures of an unacceptable number of people at risk.
Antimicrobial resistance (AMR) occurs when microorganisms such as bacteria, viruses, fungi and parasites come into contact with antimicrobial drugs, such as antibiotics, antivirals, antifungals, antimalarials and anthelmintics, and undergo changes. The drugs are rendered ineffective and cannot eradicate infections from the body.
AMR is an international challenge that threatens to reverse over a century of progress in public health, health care and human development attributable to antimicrobial use. Indeed, the effects of AMR are already being felt across Canada’s health care system. Currently, Canada’s dedicated investment in solutions to militate against encroaching AMR in the AMR and antimicrobial stewardship (AMS) fields (both federally and provincially/territorially) can only be viewed as wholly inadequate to address the scope of the problem and the risks it poses for the health of Canadians.
Therefore, to: (1) promote awareness of AMR; (2) incentivize investment in AMR mitigation strategies; and (3) support the mobilization of an effective suite of more clinically effective management/treatment practices and policies, the following target audience recommendations are offered.a
a All the policy recommendations made in this document are not meant to be interpreted as clinical practice guidelines. Any individual who suspects they may have an infection should promptly consult a physician.
Key AMR principle — the “One Health” approach
a) The complexity of AMR underscores the need for coordinated action known as the “One Health” approach. The term implies integrated strategies that span the human, animal/agricultural and environmental sectors. Thus, cooperation across a wide variety of stakeholders is necessary to address the collective nature of AMR. These stakeholders include governments, health professionals, private and public partners, and the public at large.
b) The One Health approach will require attention and investment in the following domains: (1) surveillance of antimicrobial prescribing and usage; (2) infection prevention and control practices that mitigate the spread of resistant pathogens; (3) stewardship programs and practices that educate health professionals, the public, and the private sector and nudge each into more appropriate patterns of supply and demand; and (4) a program of innovation, research and development focused on diagnostics, vaccines and alternative treatments to reduce reliance on antimicrobials. This includes the development of novel antimicrobials that expand the currently available arsenal.
c) Given the global dimensions of AMR, a successful One Health approach will require ambitious investments in global AMR mitigation. Given that health infrastructure and resources are limited in low- to middle-income countries, the impacts of AMR will primarily be felt in those settings.
1. Physicians and allied health professionals
a) Be aware that AMR is a serious public health crisis.
b) Know that various Canadian prescribing aides/guidelines are available to assist physicians in choosing appropriate antibiotics and improving practice (e.g., Choosing Wisely Canada).
c) Know that using antibiotics appropriately can help combat AMR and that diagnosis and laboratory testing play a key role. This includes only prescribing antibiotics for conditions that are clinically infectious and of a non-viral nature. Viral infections are the greatest source of antibiotic misuse.
d) Consider delayed prescriptions and/or prioritize follow-up for patients when diagnosis is initially undifferentiated or when symptoms worsen, progress or are prolonged.
e) Know that prevention of infections through hand hygiene, vaccination and appropriate use of antibiotic prophylaxis is evidence based and effective
f) Know that durations of therapy and dosage rates for treating many infections change with time and that you should prescribe antimicrobials for the shortest effective duration (using the narrowest spectrum possible).
g) Consider the potential side effects of antibiotics (including C. difficile and allergic reactions) in prescribing and when counselling patients as to their potential side effects.
h) Engage in conversations with patients about antimicrobials regarding:
i. their appropriate use;
ii. their potential risks;
iii. when to delay, begin or end an antimicrobial prescription (e.g., delayed prescriptions); and
iv. when to seek medical reassessment if symptoms worsen or persist.
i) Ask your local hospital or specialty organization about educational initiatives related to antibiotic prescribing.
j) Collaborate where possible with colleagues in other prescribing professions to reduce unnecessary antimicrobial use.
2. Patients and the Canadian public
a) Be aware that AMR is a significant problem that is linked to the inappropriate use of antimicrobials like antibiotics. Therefore, commit to only taking antibiotics if they are prescribed and only as directed by an authorized health professional.
i. Never share, or use, the antibiotics of others as it may contribute to AMR and have serious consequences for your health.
b) Consider that your expectations about antimicrobials may unduly pressure physicians, and other prescribers, to provide you a prescription when an antimicrobial would not be appropriate or helpful.
c) Engage in a conversation with prescribers about:
i. whether an antimicrobial is necessary;
ii. the risks associated with taking an antimicrobial;
iii. whether there are simpler and safer options to pursue; and
iv. when you should take further actions if your symptoms worsen or do not improve.
d) Rather than keeping antimicrobials in your medicine cabinet, throwing them in the garbage/toilet or sharing them with family or friends, practise a One Health mindset. Dispose of all unused and expired antimicrobials at your local pharmacy. This will limit the spread of resistance and prevent antimicrobials from finding their way into the environment.
e) Help limit resistance by staying up to date with all recommended vaccinations, and practise good hand hygiene.
f) If you or a family member have had personal experiences with AMR, consider sharing them with local politicians (provincial/territorial and federal).
3. Governments (federal, provincial/territorial)
a) (Including internationally) immediately make substantial, long term, coordinated and directly dedicated financial investments in AMR and AMS. Specific areas to prioritize include:
i. AMR and AMS awareness campaigns targeted to the public;
ii. campaigns that support health professionals to incorporate AMS principles into their everyday practice;
iii. detailed, and integrated, action plans based on clear metrics of success and that address the needs of communities, primary care practitioners, patients and health care organizations (including long-term care facilities);
iv. practical surveillance of antimicrobial resistance, purchasing, prescribing and use that maximizes the opportunity to respond to changing landscapes;
v. studying in detail the links, and associated risks, between animal health and agricultural practices and human health;
vi. scaling up local AMS initiatives at the provincial/territorial and national health care delivery levels;
vii. pharmaceutical development pipelines and non-pharmacological treatment options for AMR infections;
viii. inexpensive, accurate and timely point-of-care diagnostic tests (usable in the community, at the bedside or in a clinic) to optimize prescribing; and
ix. fostering clinical research, development and innovation in the fields of AMR and AMS.
b) Scale up coordination between federal and provincial/territorial AMR and AMS activities.
c) Hold regular, high-level meetings of ministers of health, agriculture and finance (both federally and provincially/territorially) to discuss the implications of unchecked AMR and how best to mobilize public finances to address it.
d) Strongly consider an arms-length, national-level taskforce to address AMR and AMS.
e) Strengthen the roles of the chief public health officer and the provincial/territorial chief medical officers in addressing AMR and AMS.
f) Undertake a timely review of the Canadian Antimicrobial Resistance Surveillance System (CARRS) with an emphasis on:
i. scaling up the system;
ii. standardizing all AMR reporting metrics across the country; and
iii. injecting adequate resources into AMR surveillance and tracking antimicrobial usage rates.
g) Establish a permanent review body on infectious disease, including pharmacists, microbiologist and other experts, to evaluate the forthcoming Pan-Canadian Action Plan on AMR and release regular progress reports.
4. Health care institutions and organizations
a) Implement strategic AMR plans that are coordinated, cross-departmental and adopted institution wide. These should be premised on:
i. standardized and comprehensive reporting metrics for AMR and antimicrobial usage;
ii. tailored infection prevention and control programs to screen for and effectively prevent new AMR infections;
iii. improving public and professional awareness of AMR organization wide;
iv. improving conservation measures such as prescribing practices (audit and feedback, incentives programs, etc.); and
v. supporting and incentivizing appropriate prescribing of antimicrobials.
b) Evaluate whether existing policies and procedures, diagnostics and testing capacities, and multidisciplinary and organizational cultures are strategically geared toward combatting AMR.
c) Where possible, develop collaborations with other local health institutions, clinical researchers and community, public and private partners to promote AMS.
5. Accreditation and regulatory bodies
a) Regularly review and establish meaningful criteria for accreditation, ethical codes and regulatory practice standards surrounding AMR and AMS so that practitioners and health institutions can be informed, supported and kept up to date on emerging AMR trends, practices and issues.
b) Adopt profession-specific mandatory requirements for AMR and AMS (proper credentialing and training, regular updating of knowledge and competence for prescribing antimicrobials, appropriate data collection regarding antimicrobial usage, etc.) as part of credentialing.
c) Work to promote, support and enhance existing AMS practices and programs.
d) Collaborate with health institutions, professional health associations and other accreditation and regulatory bodies to implement AMS goals/plans.
6. Colleges and faculties for medicine and allied health professions
a) Promote and support more educational resources for AMS and AMR, throughout the continuum of education (undergraduate, postgraduate and continuing education).
i. Topics for these resources should include (1) awareness of AMR and AMS, (2) appropriate diagnostic testing, (3) strategies to minimize antimicrobial use and (4) personal prescribing practices.
b) Promote and support research on AMR and the implementation and dissemination of effective AMS strategies.

BACKGROUND TO CMA POLICY
See also CMA Policy Antimicrobial Resistance PD19-08
The world is at the tipping point of a post-antibiotic era. “Worldwide, we are relying more heavily on antibiotics to ensure our medical, nutritional, and economic security; while simultaneously causing the decline of their usefulness with overuse and ill-advised use.” It is estimated that the world’s use of antimicrobials increased by 65% between 2000 and 2015 — mainly in low- to middle-income countries.
Dr. Margaret Chan, the former head of the World Health Organization (WHO), described antimicrobial resistance (AMR) as a slow-moving tsunami for public health. Other experts have characterized AMR as a looming “antibiotic apocalypse,” warning that all countries “will face disastrous consequences if the spread of AMR is not contained.” Others are now calling AMR the “climate change” of health care. According to the UK’s review on AMR, an estimated 10 million people globally will die annually by 2050, and AMR will surpass cancer to become the leading cause of death.
AMR occurs when “microorganisms (such as bacteria, fungi, viruses, and parasites) change when they are exposed to antimicrobial drugs (such as antibiotics, antifungals, antivirals, antimalarials, and anthelmintics). … As a result, the medicines become ineffective and infections persist in the body, increasing the risk of spread to others.” Microorganisms that develop antimicrobial resistance are sometimes referred to as “superbugs.” “Nightmare bacteria,” as they have been dubbed, are bacterial strains that no conventional antimicrobial can effectively treat; their incidence is on the rise.
AMR represents a unique challenge for the medical profession as it is estimated that as many as 50% of current antibiotic prescriptions are either inappropriate or unnecessary. In addition, taking an antimicrobial involves potentially considerable exposure to side effects or risk. At stake are many currently routine, and lifesaving, forms of medical treatment. Critically, these include many medications for currently treatable bacterial infections, and many forms of surgery (including cesarean delivery), radiation therapy, chemotherapy and neonatal care.4
THE UNDERLYING DYNAMICS OF AMR
AMR is driven by a complex set of interlocking factors. These include: (1) increased global travel and medical tourism; (2) inappropriate, and unnecessarily high, use of antimicrobials in the agrifood sector; (3) poor medical prescribing practices; (4) inadequate implementation of infection prevention and control measures; (5) lack of knowledge, inappropriate expectations and misuse of antimicrobials on the part of the general public; (6) availability of poor-quality antimicrobials; (7) lack of access to rapid, affordable and accurate rapid diagnostic tools and infrastructure; (8) inadequate and underused surveillance data from AMR surveillance systems; (9) international travel rates; and (10) low commercial interest in, or support for, new antimicrobial research and development.
To make progress on AMR, we need to carefully think about how to address its various drivers. Antimicrobial stewardship (AMS) is a term describing coordinated efforts, at any program level, to: (1) promote the appropriate use of antimicrobials; (2) improve patient outcomes; (3) reduce microbial resistance and preserve the effectiveness of antimicrobials; and (4) decrease the spread of infections caused by multidrug-resistant organisms. AMS efforts are based on the “One Health” approach. These include: (1) surveillance; (2) conservation of existing AM effectiveness; (3) innovation through research and development; and (4) infection prevention and control.
Fundamentally, AMR can be thought of as a collective action problem, similar in character to the problem of climate change.3, While all stakeholders have a role to play in combatting AMR, each has very different resources, abilities and perspectives on AMR. Canada and much of the developed world have the luxury of health infrastructures, finances and regulatory frameworks that can make AMR mitigation possible. But in low- to middle-income countries — places where antibiotics might be the only real health care available — the very discussion of AMS can be perceived as threatening. Simply put, this illustrates the fact that solutions to AMR need to mobilize and leverage a collective strategy that is as broad and as connected as possible. To be successful, these solutions will need to do so in a manner that acknowledges the local reality of health care delivery.
Global investment in antimicrobial research and development is underwhelming, a dynamic described as a “drying up” of the pharmaceutical pipeline.8 This is evidenced by the recent large-scale withdrawal of major pharmaceutical companies from antimicrobial research and development, reflecting the lack of profitability in this area. On the pharmaceutical side, there are clear barriers to companies investing in the development of novel antimicrobials. Underlying factors include: (1) 10-year timelines, and an estimated minimum $1 billion price tag for development; (2) high development failure rates for new antimicrobials; (3) the inevitable emergence of resistance to any newly developed antimicrobial; (4) antimicrobials being offered at relatively cheap dosage rates over shorter durations of use; and (5) the need to preserve the efficacy of any antimicrobial’s future use, which limits their economic viability.8
WHAT ARE THE CANADIAN CONTEXTS?
AMR is already a major costly public health challenge in both the US and Canada. AMR infections are clearly linked to poorer health outcomes, longer hospital stays and higher mortality rates.3 The Public Health Agency of Canada (PHAC) estimates that roughly 18,000 hospitalized Canadians contract drug-resistant infections per year. The Canadian Patient Safety Institute estimates that 8,000 Canadian patients die annually with an AMR-related infection. It is estimated that close to 23 million antibiotic prescriptions are written annually for patients in Canada, the approximate equivalent to 1.6% of the population being on an antimicrobial on any given day.
An action plan in Canada is being developed by PHAC. On the surface, the action plan appears comprehensive in that it outlines a One Health approach.10 However, despite commitments to take comprehensive, measurable action on AMS, Canadian leadership on AMR has historically lagged because of a lack of concrete coordination between PHAC and the provinces and because it has been challenging to implement local initiatives systemically.
Previous shortcomings were highlighted in the Auditor General of Canada’s 2015 report and again in a 2017 issue brief by HealthCareCAN.18 Although efforts continue and the action plan is set for release at some point in 2019, concerns remain that: (1) the scope of coordinated efforts with the provinces and territories requires an interest in cooperation that may not exist between the two levels of government; (2) relative to the scope of the problem, sufficient and dedicated resources won’t be allocated; and (3) efforts on the industrial and agricultural fronts may not be sufficiently coordinated with AMR efforts for human health.
In the spring of 2018 the House of Commons Standing Committee on Health (HESA) released a report outlining 10 recommendations for action on AMR in Canada. Although the federal government “accepted” most of the committee’s recommendations, no meaningful (and dedicated) AMR funding has been announced in advance of the action plan’s launch. Indeed, the federal government’s response to the HESA report sought to downplay the need for either urgent action or additional resources. This was done by pointing to nominal federal AMR efforts over the span of more than a decade.
It should be noted that a small number of excellent localized AMS initiatives exist and have begun yielding promising local AMS results in Canada. AMR and AMS champions such as Choosing Wisely Canada, Do Bugs Need Drugs, and the Association of Medical Microbiology and Infectious Disease Canada have long argued that with proper resourcing, localized initiatives can be scaled up to a systemic level of application within provincial health care systems.
GLOBALLY, WHERE DOES AMR STAND?
Urgent action is required at an international level to combat AMR. Although AMR remains a complex public health challenge, the benefits of AMS are clear. The preservation of these precious resources will save lives and can positively affect both quality of care and health care delivery costs.7,14 Globally, many higher income nations and, increasingly, middle-income countries have now developed AMR/AMS action plans. Like the situation in Canada, these emerging and existing global action strategies remain largely unimplemented. Initial cash infusions into the AM drug development pipeline are beginning to emerge.8
Despite this, experts warn that such investments are too short term and wholly inadequate to address the scope of the looming AMR crisis.8, This reflects the many complexities that exist in the implementation of AMR action plans, owing in large part to: (1) a general lack of resources or prioritization; (2) complacency about AMR as a pressing public health concern; (3) difficulties in generalizing local AMS efforts; (4) coordination between sectorial actors; and (5) a lack of tangible AMR metrics and evidence.
If AMS gains are to be made in low- and middle-income countries, the impact of limited resources in those settings will need to be considered.13 Realistically these countries will require various forms of monetary incentives and assistance to be able to effectively adopt AMR programs. If such support is not provided, human health rights will be affected and global AMS efforts will be undermined. Finally, there are now well-established calls for an international model, even a treaty, to be implemented on AMR/AMS.12,
The CMA recommends to the appropriate government authorities that all boxing be banned in Canada. Until such time, strategies to prevent injury should be pursued.
The CMA considers boxing a dangerous sport. While most sports involve risk of injury, boxing is distinct in that the basic intent of the boxer is to harm and incapacitate his or her opponent.
Boxers are at significant risk of injuries resulting in brain damage. Boxers are susceptible not only to acute life-threatening brain trauma, but also to the chronic and debilitating effects of gradual cerebral atrophy. Studies demonstrate a correlation between the number of bouts fought and the presence of cerebral abnormalities in boxers. There is also a risk of eye injury including long-term damage such as retinal tears and detachments.
- CMA supports a ban on professional and amateur boxing in Canada.
- Until boxing is banned in this country, the following preventive strategies should be pursued to reduce brain and eye injuries in boxers:
- Head blows should be prohibited. CMA encourages universal use of protective garb such as headgear and thumbless, impact-absorbing gloves
- The World Boxing Council, World Boxing Association and other regulatory bodies should develop and enforce objective brain injury risk assessment tools to exclude individual boxers from sparring or fighting.
- The World Boxing Council, World Boxing Association and other regulatory bodies should develop and enforce standard criteria for referees, ringside officials and ringside physicians to halt sparring or boxing bouts when a boxer has experienced blows that place him or her at imminent risk of serious injury.
- The World Boxing Council, World Boxing Association and other regulatory bodies should encourage implementation of measures advocated by the World Medical Boxing Congress to reduce the incidence of brain and eye injuries.
- CMA believes that the professional responsibility of the physician who serves in a medical capacity in a boxing contest is to protect the health and safety of the contestants. The desire of spectators, promoters of the event, or even injured athletes that they not be removed from the contest should not influence the physician’s medical judgment.
- Further long term outcome data should be obtained from boxers in order to more accurately establish successful preventive interventions. CMA encourages ongoing research into the causes and treatments of boxing-related injuries, and into the effects of preventive strategies.
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

Inherent in all health care professional Codes of Ethics is the duty to provide care to patients and to relieve suffering whenever possible. However, this duty does not exist in a vacuum, and depends on the provision of goods and services referred to as reciprocal obligations, which must be provided by governments, health care institutions and other relevant bodies and agencies. The obligation of government and society to physicians can be seen as comparable to the obligations of physicians to their patients.
The recent experience of Canadian physicians during the SARS epidemic in Toronto has heightened the sensitivities of the medical profession to several issues that arose during the course of dealing with that illness. Many of the lessons learned (and the unanswered questions that arose) also apply to the looming threat of an avian flu (or other) pandemic. Canadian physicians may be in a relatively unique position to consider these issues given their experience and insight.
The intent of this working paper is to highlight the ethical issues of greatest concern to practicing Canadian physicians which must be considered during a pandemic. In order to address these issues before they arise, the CMA presents this paper for consideration by individual physicians, physician organizations, governments, policy makers and interested bodies and stakeholders. Although many of the principles and concepts could readily be applied to other health care workers, the focus of this paper will be on physicians.
Policies regarding physicians in training, including medical students and residents, should be clarified in advance by the relevant bodies involved in their oversight and training. Issues of concern would include the responsibilities of trainees to provide care during a pandemic and the potential effect of such an outbreak on their education and training.
A. Physician obligations during a pandemic
The professional obligations of physicians are well spelled out in the CMA Code of Ethics and other documents and publications and are not the main focus of this paper. However, they will be reviewed and discussed as follows.
Several important principles of medical ethics will be of particular relevance in considering this issue. Physicians have an obligation to be beneficent to their patients and to consider what is in the patient's best interest. According to the first paragraph of the CMA Code of Ethics (2004), "Consider first the well-being of the patient".
Traditionally, physicians have also respected the principle of altruism, whereby they set aside concern for their own health and well-being in order to serve their patients. While this has often manifested itself primarily as long hours away from home and family, and a benign neglect of personal health issues, at times more drastic sacrifices have been required. During previous pandemics, many physicians have served selflessly in the public interest, often at great risk to their own well-being.
The principle of justice requires physicians to consider what is owed to whom and why, including what resources are needed, and how these resources would best be employed during a pandemic. These resources might include physician services but could also include access to vaccines and medications, as well as access to equipment such as ventilators or to a bed in the intensive care unit. According to paragraph 43 of the CMA Code of Ethics, physicians have an obligation to "Recognize the responsibility of physicians to promote equitable access to health care resources".
In addition, physicians can reasonably be expected to participate in the process of planning for a pandemic or other medical disaster. According to paragraph 42 of the CMA Code of Ethics, physicians should "Recognize the profession's responsibility to society in matters relating to public health, health education, environmental protection, legislation affecting the health and well-being of the community and the need for testimony at judicial proceedings". This responsibility could reasonably be seen to apply both to individual physicians as well as the various bodies and organizations that represent them.
Physicians also have an ethical obligation to recognize their limitations and the extent of the services they are able to provide. During a pandemic, physicians may be asked to assume roles or responsibilities with which they are not comfortable, nor prepared. Paragraph 15 of the CMA Code of Ethics reminds physicians to "Recognize your limitations and, when indicated, recommend or seek additional opinions or services".
However, physicians have moral rights as well as obligations. The concept of personal autonomy allows physicians some discretion in determining where, how and when they will practice medicine. They also have an obligation to safeguard their own health. As stated in paragraph 10 of the CMA Code of Ethics, physicians should "Promote and maintain your own health and well-being".
The SARS epidemic has served to reopen the ethical debate. Health care practitioners have been forced to reconsider their obligations during a pandemic, including whether they must provide care to all those in need regardless of the level of personal risk. As well, they have been re-examining the obligation of governments and others to provide reciprocal services to physicians, and the relationship between these obligations.
B. Reciprocal obligations towards physicians
While there has been much debate historically (and especially more recently) about the ethical obligations of physicians towards their patients and society in general, the consideration of reciprocal obligations towards physicians is a relatively recent phenomenon.
During the SARS epidemic, a large number of Canadian physicians unselfishly volunteered to assist their colleagues in trying to bring the epidemic under control. They did so, in many cases, in spite of significant personal risk, and with very little information about the nature of the illness, particularly early in the course of the outbreak. Retrospective analysis has cast significant doubt and concern on the amount of support and assistance provided to physicians during the crisis. Communication and infrastructure support was poor at best. Equipment was often lacking and not always up to standard when it was available. Psychological support and counselling was not readily available at the point of care, nor was financial compensation for those who missed work due to illness or quarantine. Although the Ontario government did provide retrospective compensation for many physicians whose practices were affected by the outbreak, the issue was addressed late, and not at all in some cases.
It is clear that Canadian physicians have learned greatly from this experience. The likelihood of individuals again volunteering "blindly" has been reduced to the point where it may never happen again. There are expectations that certain conditions and obligations will be met in order to optimize patient care and outcomes and to protect health care workers and their families.
Because physicians and other health care providers will be expected to put themselves directly in harm's way, and to bear a disproportionate burden of the personal hardships associated with a pandemic, the argument has been made that society has a reciprocal obligation to support and compensate these individuals.
According to the University of Toronto Joint Centre for Bioethics report We stand on guard for thee, "(The substantive value of) reciprocity requires that society support those who face a disproportionate burden in protecting the public good, and take steps to minimize burdens as much as possible. Measures to protect the public good are likely to impose a disproportionate burden on health care workers, patients and their families."
Therefore, in order to provide adequate care for patients, the reciprocal obligation to physicians requires providing some or all of the following:
Prior to a pandemic
- Physicians and the organizations that represent them should be more involved in planning and decision making at the local, national and international levels. In turn, physicians and the organizations that represent them have an obligation to participate as well.
- Physicians should be made aware of a clear plan for resource utilization, including:
- how physicians will be relieved of duties after a certain time;
- clearly defined roles and expectations, especially for those practicing outside of their area of expertise;
- vaccination/treatment plans - will physicians (and their families) have preferential access based on the need to keep caregivers healthy and on the job;
- triage plans, including how the triage model might be altered and plans to inform the public of such.
- Physicians should have access to the best equipment needed and should be able to undergo extra training in its use if required.
- Politicians and leaders should provide reassurances that satisfy physicians that they will not be "conscripted" by legislation.
During a pandemic
- Physicians should have access to up-to-date, real time information.
- Physicians should be kept informed about developments in Canada and globally.
- Communication channels should be opened with other countries (e.g. Canada should participate in WHO initiatives to identify the threats before they arrive on our doorstep).
- Resources should be provided for backup and relief of physicians and health care workers.
- Arrangements should be made for timely provision of necessary equipment in an ongoing fashion.
- Physicians should be compensated for lost clinical earnings and to cover expenses such as lost wages, lost group earnings, overhead, medical care, medications, rehabilitative therapy and other relevant expenses in case of quarantine, clinic cancellations or illness (recognizing that determining exactly when or where an infection was acquired may be difficult).
- Families should receive financial compensation in the case of a physician family member who dies as a result of providing care during a pandemic.
- In the event that physicians may be called upon in a pandemic to practice outside of their area of expertise or outside their jurisdiction, they should to contact their professional liability protection provider for information on their eligibility for protection in these circumstances.
- Interprovincial or national licensing programs should be developed to provide physicians with back-up and relief and ensure experts can move from place to place in a timely fashion without undue burden.
- Psychological and emotional counselling and support should be provided in a timely fashion for physicians, their staff and family members.
- Accommodation (i.e. a place to stay) should be provided for physicians who have to travel to another locale to provide care; or who don't want to go home and put their family at risk, when this is applicable, i.e. the epidemiology of the infectious disease causing the pandemic indicates substantially greater risk of acquiring infection in the health care setting than in the community.
- Billing and compensation arrangements should ensure physicians are properly compensated for the services they are providing, including those who may not have an active billing number in the province where the services are being provided.
After a pandemic
- Physicians should receive assistance in restarting their practice (replacing staff, restocking overhead, communicating with patients, and any other costs related to restarting the practice).
- Physicians should receive ongoing psychological support and counselling as required.
C. How are physician obligations and reciprocal obligations related?
Beyond a simple statement of the various obligations, it is clear that there must be some link between these different obligations. This is particularly important since there is now some time to plan for the next pandemic and to ensure that reciprocal obligations can be met prior to its onset. Physicians have always provided care in emergency situations without questioning what they are owed. According to paragraph 18 of the CMA Code of Ethics, physicians should "Provide whatever appropriate assistance you can to any person with an urgent need for medical care".
However, in situations where obligations can be anticipated and met in advance, it is reasonable to expect that they will be addressed. Whereas a physician who encounters an emergency situation at the site of a car crash will act without concern for personal gain or motivation, a physician caring for the same patient in an emergency department will rightly expect the availability of proper equipment and personnel.
In order to ensure proper patient care and physician safety, and to ensure physicians are able to meet their professional obligations and standards, the reciprocal obligations outlined above should be addressed by the appropriate body or organization.
If patient and physician well-being is not optimized by clarifying the obligations of physicians and society prior to the next pandemic, in spite of available time and resources necessary to do so, there are many who would call into question the ethical duty of physicians to provide care. However, the CMA believes that, in the very best and most honourable traditions of the medical profession, its members will provide care and compassion to those in need. We call on governments and society to assist us in optimizing this care for all Canadians.
Climate Change and Human Health
Climate change is increasingly recognized as a significant threat facing society and has the potential to be one of the greatest threats to human health in the 21st Century1. While the damage is being done now, many of the health effects may arise only decades in the future2.
Possible impacts could include some or all of the following:
* Increased mortality, disease and injuries from heat waves and other extreme weather events;
* Continued change in the range of some infectious disease vectors (i.e. 260-320 million more cases of malaria predicted by 2080, with six billion more at risk for dengue fever);
* Effects on food yields- increased malnutrition;
* Increased flooding in some areas and increased droughts in others, along with other impacts on freshwater supply;
* Increases in foodborne and waterborne illnesses;
* Warming and rising sea levels adding to displacement and also impacting water supply through salination;
* Impaired functioning of ecosystems;
* Negative effects on air quality associated with ground level ozone, including increases in cardio-respiratory morbidity and mortality, asthma, and allergens;
* Displacement of vulnerable populations (especially in coastal areas)1; and
* Loss of livelihoods3.
Most of the impacts of climate change will result from amplifying the existing health hazards found in populations4. How susceptible a population is to the effects of climate change is dependent on their existing vulnerabilities (i.e. disease burden, resources etc.) as well as their adaptive capacity5. The World Health Organization has projected that countries that have, and will likely continue to suffer the greatest effects, are those who have contributed the smallest amount to the causes of climate change.6
While the vast majority of climate change deaths will occur in developing countries with systemic vulnerabilities, a recent Health Canada report has noted that Canada is likely to experience higher rates of warming in this century than most other countries in the world. Climate change scenarios predict an increased risk of extreme weather and other climate events for all regions of Canada, with the exception of extreme cold7. Canadians most vulnerable to climate change include seniors, children and infants, socially disadvantaged individuals, and those with pre-existing medical conditions such as cardiovascular disease8. Those living in cities could be especially vulnerable due to the impact of the heat island effect. However, given their greater access to emergency, health, social, and financial resources, they might also have the greatest adaptive capacity9.
The health consequences of climate change have the potential to be more severe in far northern regions. Populations in Canada's north including aboriginals have already begun to see differences in their hunting practices as a result of changing ice patterns10, and the melting of permanent snowpacks11. Changes in ice patterns have also led to increased injuries12. In some places in the North, climate changes have led to greater risks from avalanches, landslides and other hazards13. Further problems are related to the infrastructure in Northern Canada, with some communities already noticing degradation of structures due to the thawing of the permafrost14. Given that much of the Northern infrastructure is already in disrepair, this represents a considerable problem. Geographic isolation, and a lack of resources may further exacerbate the situation15.
What CMA has done?
Physicians have a critical role to play in advancing public understanding of the potential impact of climate change on health and promoting health protecting responses.
The CMA has been working on the issue of climate change and human health for a number of years. CMA was supportive of Canada's ratification of the Kyoto Protocol, and urged the Government of Canada to commit to choosing a climate change strategy that satisfied Canada's international commitments while also maximizing the clean air co-benefits and smog-reduction potential of any greenhouse gas reduction initiatives.
In 2007, a number of resolutions were passed at General Council calling on government to properly plan for the health impacts of climate change and put in place measures to mitigate the impact of climate change on vulnerable populations in Canada's north. In that same year, CMA and the Canadian Nurses Association updated a joint position statement first entered into in 1994 calling for environmentally responsible activity in the health-care sector.
Most recently, the CMA has been an integral part of the drafting of the World Medical Association (WMA) policies on health and climate change. The WMA Declaration of Delhi on Health and Climate Change was adopted at its annual General Assembly in New Delhi, India in October 2009, The declaration calls for action in five main areas; advocacy to combat global warming; leadership-help people be healthy enough to adapt to climate change; education and capacity building; surveillance and research; and collaboration to prepare for climate emergencies. This policy is written to complement the WMA declaration.
What needs to be done?
Climate change may lead to significant impacts on human health. While it is unlikely that these outcomes can be avoided, there are some strategies that can be employed to help limit the negative consequences.
Education and Capacity Building
There is a need for greater public and health professional awareness and education about climate change in order to gain understanding of the health consequences and support for strategies to reduce green house gases and mitigate climate change effects.
1. A national public awareness program on the importance of the environment and global climate change to personal health;
2. Encouraging health sciences schools to enhance their provision of educational programs on environmental health; and fostering the development of continuing education modules on environmental health and environmental health practices.
Surveillance and Research
There are important gaps in our knowledge on the health impacts of climate change as well as the effectiveness of various mitigation and adaptation strategies. Surveillance and reporting functions need to be strengthened to allow for greater accuracy in modeling of future impacts.
3. That the federal government must address the gaps in research regarding climate change and health by undertaking studies to
- quantify and model the burden of disease that will be caused by global climate change
- identify the most vulnerable populations, the particular health impacts of climate change on vulnerable populations, and possible new protections for such populations;
- increase the collection and accuracy of health data, particularly for vulnerable and underserved populations;
- report diseases that emerge in conjunction with global climate change, and participate in field investigations, as with outbreaks of infectious diseases; and
- develop and expand surveillance systems to include diseases caused by global climate change.
Reducing the Burden of Disease to Mitigate Climate Change Impacts
How susceptible a population is to the effects of climate change is dependent on their existing vulnerabilities. Therefore, work needs to be done to reduce the burden of diseases and improve upon the social determinants of health for vulnerable populations in Canada and globally.
4. That the federal and provincial/territorial governments work together to improve the ability of the public to adapt to climate change and catastrophic weather events by
- Encouraging behaviours that improve overall health,
- Creating targeted programs designed to address specific exposures,
- Providing health promotion information and education on self-management of the symptoms of climate-associated illness,
- Ensuring physical infrastructure that allows for adaptation;
5. That the federal government develop concrete actions to reduce the health impact of climate-related emissions, in particular those initiatives which will also improve the general health of the population;
6. That the federal government support the Millennium Development Goals and support the principles outlined in the WHO Commission on the Social Determinants of Health report; and
Preparing for Climate Emergencies
To deal with the future burden of climate change related health issues there is a need to ensure adequate health capacity and infrastructure. Rebuilding of public health capacity globally is seen as the most important, cost-effective, and urgently needed response to climate change16. Domestically, there is a need to ensure adequate surge capacity within the health care system to be prepared for an increase in illness related to climate change effects. There is also a need to strengthen not only the health systems, but the infrastructure (i.e. housing) for vulnerable populations including Aboriginals and those in the North.
CMA recommends that the federal and provincial /territorial governments work together to:
7. Strengthen the public health system both domestically and internationally in order to improve the capacity of communities to adapt to climate change;
8. Ensure adequate surge capacity within Canada's health system to handle the increase in climate change related illness;
9. Ensure the health of vulnerable populations is adequate to handle climate change related situations;
10. Develop knowledge about the best ways to adapt to and mitigate the health effects of climate change;
11. Integrate health professionals into the emergency preparedness plans of government and public health authorities so that front-line providers are adequately informed and prepared to properly manage any health emergencies.
Advocacy to Combat Climate Change
Finally, there is a need to take action to reduce the damaging effects of climate change. The global community needs to come together to reduce the levels of green house gases being released in the atmosphere, and focus on safer more environmentally friendly energy sources. Investments in cuts to greenhouse gas emissions would greatly outweigh their costs, and could help to reduce the future burden of climate change related illness17.
12. That the government of Canada become a global leader in promoting equitable, carbon neutral economic, industrial, and social policies, and practices that fight global warming and adopt specific green house gas reduction targets as determined by the evolving science of climate change.
13. That health care professionals act within their professional settings to reduce the environmental impact of medical activities and to develop environmentally sustainable professional settings;
14. That all Canadians act to minimize individual impacts on the environment, and encourage others to do so, as well.
The CMA believes that Canada must prepare now for the potential health threat that climate change poses to its population. While many of these effects will take decades to materialize, certain populations, such as those in Canada's north, or those in low lying coastal areas, are already starting to experience the impact of climate change.
A focus on education and health promotion, as well as advocacy for improved public policy and primary health care resources will be a good start in dealing with this issue. Additionally, further research and data collection is necessary to improve our understanding of climate change and the effectiveness of adaptation and mitigation strategies.
Finally, the global community needs to act together to address the health and environmental impacts of climate change. By working together, in an international response, strategies can be implemented to mitigate any negative health effects of climate change.
Canada's physicians believe that: What is good for the environment is also good for human health. It is past time for those of us in the health sector in Canada to engage fully in the debate and discussions within our own house, as well as in the broader body politic to ensure that protecting human health is the bottom line of environmental and climate change strategies.

CMA CODE OF ETHICS AND PROFESSIONALISM
A compassionate physician recognizes suffering and vulnerability, seeks to understand the unique circumstances
of each patient and to alleviate the patient’s suffering, and accompanies the suffering and vulnerable patient.
An honest physician is forthright, respects the truth, and does their best to seek, preserve, and communicate
that truth sensitively and respectfully.
A humble physician acknowledges and is cautious not to overstep the limits of their knowledge and skills or the
limits of medicine, seeks advice and support from colleagues in challenging circumstances, and recognizes the
patient’s knowledge of their own circumstances.
A physician who acts with integrity demonstrates consistency in their intentions and actions and acts in a
truthful manner in accordance with professional expectations, even in the face of adversity.
A prudent physician uses clinical and moral reasoning and judgement, considers all relevant knowledge
and circumstances, and makes decisions carefully, in good conscience, and with due regard for principles of
exemplary medical care.
The CMA Code of Ethics and Professionalism articulates the ethical and professional commitments and responsibilities of the
medical profession. The Code provides standards of ethical practice to guide physicians in fulfilling their obligation to provide
the highest standard of care and to foster patient and public trust in physicians and the profession. The Code is founded on
and affirms the core values and commitments of the profession and outlines responsibilities related to contemporary medical
In this Code, ethical practice is understood as a process of active inquiry, reflection, and decision-making concerning what
a physician’s actions should be and the reasons for these actions. The Code informs ethical decision-making, especially in
situations where existing guidelines are insufficient or where values and principles are in tension. The Code is not exhaustive;
it is intended to provide standards of ethical practice that can be interpreted and applied in particular situations. The Code and
other CMA policies constitute guidelines that provide a common ethical framework for physicians in Canada.
In this Code, medical ethics concerns the virtues, values, and principles that should guide the medical profession, while
professionalism is the embodiment or enactment of responsibilities arising from those norms through standards,
competencies, and behaviours. Together, the virtues and commitments outlined in the Code are fundamental to the ethical
practice of medicine.
Physicians should aspire to uphold the virtues and commitments in the Code, and they are expected to enact the professional
responsibilities outlined in it.
Physicians should be aware of the legal and regulatory requirements that govern medical practice in their jurisdictions.
Trust is the cornerstone of the patient–physician relationship and of medical professionalism. Trust is therefore
central to providing the highest standard of care and to the ethical practice of medicine. Physicians enhance
trustworthiness in the profession by striving to uphold the following interdependent virtues:
A. VIRTUES EXEMPLIFIED BY THE ETHICAL PHYSICIAN
B. FUNDAMENTAL COMMITMENTS OF THE MEDICAL PROFESSION
Consider first the well-being of the patient; always act to benefit the patient and promote the good of the patient.
Provide appropriate care and management across the care continuum.
Take all reasonable steps to prevent or minimize harm to the patient; disclose to the patient if there is a
risk of harm or if harm has occurred.
Recognize the balance of potential benefits and harms associated with any medical act; act to bring about
a positive balance of benefits over harms.
Commitment to the well-being of the patient
Promote the well-being of communities and populations by striving to improve health outcomes and
access to care, reduce health inequities and disparities in care, and promote social accountability.
Commitment to justice
Practise medicine competently, safely, and with integrity; avoid any influence that could undermine
your professional integrity.
Develop and advance your professional knowledge, skills, and competencies through lifelong learning.
Commitment to professional integrity and competence
Always treat the patient with dignity and respect the equal and intrinsic worth of all persons.
Always respect the autonomy of the patient.
Never exploit the patient for personal advantage.
Never participate in or support practices that violate basic human rights.
Commitment to respect for persons
Contribute to the development and innovation in medicine through clinical practice, research, teaching,
mentorship, leadership, quality improvement, administration, or advocacy on behalf of the profession or
Participate in establishing and maintaining professional standards and engage in processes that support
the institutions involved in the regulation of the profession.
Cultivate collaborative and respectful relationships with physicians and learners in all areas of medicine
and with other colleagues and partners in health care.
Commitment to professional excellence
Value personal health and wellness and strive to model self-care; take steps to optimize meaningful
co-existence of professional and personal life.
Value and promote a training and practice culture that supports and responds effectively to colleagues in
need and empowers them to seek help to improve their physical, mental, and social well-being.
Recognize and act on the understanding that physician health and wellness needs to be addressed at
individual and systemic levels, in a model of shared responsibility.
Commitment to self-care and peer support
Value and foster individual and collective inquiry and reflection to further medical science and to
facilitate ethical decision-making.
Foster curiosity and exploration to further your personal and professional development and insight; be
open to new knowledge, technologies, ways of practising, and learning from others.
Commitment to inquiry and reflection
C. PROFESSIONAL RESPONSIBILITIES
The patient–physician relationship is at the heart of the practice of medicine. It is a relationship of trust that recognizes the
inherent vulnerability of the patient even as the patient is an active participant in their own care. The physician owes a duty of
loyalty to protect and further the patient’s best interests and goals of care by using the physician’s expertise, knowledge, and
prudent clinical judgment.
In the context of the patient–physician relationship:
1. Accept the patient without discrimination (such as on the basis of age, disability, gender identity or expression, genetic
characteristics, language, marital and family status, medical condition, national or ethnic origin, political affiliation, race,
religion, sex, sexual orientation, or socioeconomic status). This does not abrogate the right of the physician to refuse to
accept a patient for legitimate reasons.
2. Having accepted professional responsibility for the patient, continue to provide services until these services are no longer
required or wanted, or until another suitable physician has assumed responsibility for the patient, or until after the
patient has been given reasonable notice that you intend to terminate the relationship.
3. Act according to your conscience and respect differences of conscience among your colleagues; however, meet your
duty of non-abandonment to the patient by always acknowledging and responding to the patient’s medical concerns and
requests whatever your moral commitments may be.
4. Inform the patient when your moral commitments may influence your recommendation concerning provision of, or
practice of any medical procedure or intervention as it pertains to the patient’s needs or requests.
5. Communicate information accurately and honestly with the patient in a manner that the patient understands and can
apply, and confirm the patient’s understanding.
6. Recommend evidence-informed treatment options; recognize that inappropriate use or overuse of treatments or
resources can lead to ineffective, and at times harmful, patient care and seek to avoid or mitigate this.

Patient privacy and the duty of confidentiality
18. Fulfill your duty of confidentiality to the patient by keeping identifiable patient information confidential; collecting,
using, and disclosing only as much health information as necessary to benefit the patient; and sharing information only
to benefit the patient and within the patient’s circle of care. Exceptions include situations where the informed consent of
the patient has been obtained for disclosure or as provided for by law.

21. Avoid health care discussions, including in personal, public, or virtual conversations, that could reasonably be seen as
revealing confidential or identifying information or as being disrespectful to patients, their families, or caregivers.
Medical decision-making is ideally a deliberative process that engages the patient in shared decision-making and is informed
by the patient’s experience and values and the physician’s clinical judgment. This deliberation involves discussion with the
patient and, with consent, others central to the patient’s care (families, caregivers, other health professionals) to support

decision-making, and safeguard the interests of the patient or public.
24. Avoid, minimize, or manage and always disclose conflicts of interest that arise, or are perceived to arise, as a result of
any professional relationships or transactions in practice, education, and research; avoid using your role as a physician to
promote services (except your own) or products to the patient or public for commercial gain outside of your treatment role.
25. Take reasonable steps to ensure that the patient understands the nature and extent of your responsibility to a third party
when acting on behalf of a third party.
26. Discuss professional fees for non-insured services with the patient and consider their ability to pay in determining fees.

Physicians and society
Concussions and head injuries are a common occurrence in sport and leisure activities, and frequently occur in occupational settings as well. While the majority of individuals who suffer from a concussion will recover with time, others may be at risk for serious and lasting complications. These include (1) children; (2) previous history of head injury or concussion; (3) prior mental health symptoms; and (4) missed diagnosis and management.
This aim of this advocacy and policy document is to improve safety during activity by raising awareness of concussions, and by working to improve the detection and safe management of concussions when they occur. It is not a clinical practice guideline. It should not be perceived as a plea to avoid sports or leisure activities, but rather as a call for safer sporting, leisure, and occupational practices. The documented health benefits that result from establishing an active lifestyle in youth and maintaining it throughout life cannot be overstated.
Achieving balance of safe play in sport, leisure and occupational activities while promoting greater physical activity levels for Canadians would have the effect of reducing health care costs in Canada, while promoting a healthier concussion recovery culture for all Canadians.
Therefore, to promote better concussion and head trauma awareness and prevention, as well as better management/treatment practices, the following policy recommendations for key target audiences across all levels of sport, leisure, and occupational activity are made.
Key Concussion & Head Injury Principles:
a) The detection of concussions and head injury should be a shared responsibility and any stakeholder/observer to such an injury should verbally raise their concerns that a concussion may have occurred.
i. It is important to understand that individuals with a possible concussion, or head injury, may not be able to recognize that they are suffering from a concussion;
ii. It is important to recognize that engrained within popular culture are dangerous notions (e.g., to minimize, ignore, downplay, or play through the pain, etc.) that cause individuals/observers to ignore the real, often hidden, dangers of such injuries.
b) Broadly speaking, access to the latest edition of the internationally recognized Concussion Recognition Tool (CRT) should be promoted/available to help identify the signs and symptoms of a possible concussion;
c) Any individual who sustains more than a minor head injury should be immediately removed from play, activity, or occupation, and not permitted to return on the same day3 (regardless of whether a concussion is later suspected).
i. These individuals should be the subject of observation for developing/evolving concussion symptoms or emergency warning signs (especially within the first 4 hours post-injury, but also up to 48 hours when red-flag symptoms are present).
d) Following first aid principles, where an individual displays signs of a serious head or spinal injury, that individual should lie still (not moving their head or neck) until a qualified individual has performed an evaluation; to determine whether emergency evacuation for medical assessment is necessary.
e) Any individual with a suspected concussion (especially where red-flag symptoms are present), or more severe traumatic brain injury, should be promptly evaluated by a physician to:
i. Either rule-out or confirm a diagnosis via an appropriate medical assessment; and
ii. Institute the provision of an age-appropriate follow-up care plan (including progressive return to school, work, and play protocols) if such an injury is confirmed.1
f) Ideally, a physician knowledgeable in concussion management determines when, and how, a concussed individual should progressively return to both cognitive (school or work) and physical activities.
g) Following a suspected, or diagnosed concussion, an individual should not return to play, or resume any activity associated with a heightened risk of head trauma, until cleared by a physician to do so.1
a) Where possible, encourage safe play practices in sports, and where appropriate, educate patients about the risks of head injuries (associated with high-risk behavior in sports, leisure and occupational activities).
b) Gain/maintain, through relevant continuous medical education, competencies related to the assessment, diagnosis and management of concussion according to most current clinical practice recommendations (e.g., latest edition of the CRT, SCAT, Child SCAT, Acute Concussion Evaluation Tool, etc.).
c) Be aware that clinical practice guidelines and assessment tools exist to assist in assessing and treating concussed individuals (e.g., Ontario Neurotrauma Foundation, Parachute Canada, etc.).
d) When assessing a patient with a potential concussion:
i. Rule out the presence of more severe traumatic brain and musculoskeletal injury;
ii. Assess for any previous concussion history, risk factors and newly arising complications;
iii. Educate and instruct parents, athletes and any individual that sustains a concussion about what to do, and what to expect, in the post concussive phase. (This should be based on the most current age-appropriate concussion management guidelines);4
iv. Provide individualized recommendations on how to optimally apply the progressive return-to-school, work, and play strategies with consideration for the specificities of the patient’s usual activities and responsibilities;4
v. Work to provide concussed patients timely access for medical reassessment in the event of worsening or persistent symptoms (including mental health); and
vi. In the presence of persistent or worsening symptoms (including mental health), consider what external, evidence based, concussion resources may be necessary as well as referral.

Industrialization and manufacturing have had enormous positive benefits for humankind, but the consequences of hazardous by-products (chemical contamination) to human health and the environment are less well recognized. A major incident such as Bhopal is an unequivocal example of catastrophic poisoning caused by industry. However, more subtle human health impacts can result from low levels of exposure to chemical and industrial by-products from agriculture, consumer products, manufacturing, and even medical sources. Chemicals from industrial sources have been found in the soil, water, air, food and human tissue. Due to improving technology, even minuscule amounts of potentially noxious substances can be detected.
Some exposures warrant remedial action, but in others the health impact may be negligible: the toxin, dose, route and duration of exposure must be considered. Of course, there are potentially toxic substances that have been found to pose little or no harm to human health, but there are many more for which the health effects are unknown. A substantial knowledge gap exists in that the effects of many chemical agents have not been fully studied. As a result, rigorous surveillance and assessment to ensure potential health impacts are reduced or avoided is necessary. Chemicals like dichlorodiphenyltrichloroethane (DDT) can persist in the environment or in living beings long after the product was pulled from the market, making it essential that full and rigorous testing of new and existing chemicals is undertaken. Finally, research is needed to determine whether emerging issues, such as the presence of pharmaceuticals in drinking water, pose a legitimate threat to human health.
Chemicals, properly managed, can and will continue to provide enormous benefits to society, but caution is warranted because of the potential health consequences. Provided below is a discussion of certain classes of chemicals that need to be regulated, monitored and properly researched.
Agriculture represents the largest component of the global economy. Rising pressures to meet the needs of a growing population have resulted in the mechanization of farming, and the widespread use of fertilizers and pesticides.1 Fertilizer and pesticide run-off has been found in soil, water and the human food supply.2 Approximately 40 chemicals classified by the International Agency for Research on Cancer (IARC) as known, probable, or possible human carcinogens, are EPA registered pesticides available on the open market.3 Long-term low dose pesticide exposure has been linked to various cancers, immune suppression, hormonal disruption, reproductive abnormalities, birth defects, and developmental and behavioural problems.4 Certain pesticides are also known to be persistent in the human body.5 While many individual pesticides can be safely used, there is a lack of research on the effect of certain pesticides when used in combination.
Modern technologies have led to advances with a positive impact on the quality of human life. While newer consumer products have benefits over earlier materials, their use is not without side effects. Both the chemicals used to make these products and those that form key components of the products themselves may be harmful. Bisphenol A (BPA) is an industrial chemical added to many hard plastic bottles and to metal based food and beverage cans since the 1960s.6 In August 2010, Statistics Canada reported that measurable levels of BPA were found in the urine of 91 per cent of Canadians aged six to 79.7 Concerns have been raised about effects on the brain, behaviour, and prostate gland from exposure to this chemical, particularly in fetuses, infants, and children.8 In 2008, Canada banned BPA in infant bottles.9 In October 2010, Canada went a step further by becoming the first jurisdiction in the world to declare BPA toxic.10
With the growing demand for consumer products, there has been a corresponding growth in manufacturing. Manufacturing is one of the biggest contributors to outdoor air pollution, and contributes to soil and water pollution.11 In 2004, US industry released 1.8 billion pounds of potentially toxic chemicals. Exposure to some of these chemicals has been linked to severe health effects, including cancer. 12 One of the released chemicals, dioxin, can be harmful at very low levels. Dioxins accumulate in fats and break down slowly. This leads to contamination of the food supply, and human exposure through the consumption of meat, dairy, fish and shellfish.13 Even in the far north, animals have been found to contain dioxins.14 The EPA estimates that the cancer risk from dioxins already present in the general public is 1-per-1,000.15 In most cases the emissions pose minimal risk to human health. However, chemicals, and chemical combinations which remain unstudied should be properly assessed.16
Advancements in medical science and the use of pharmaceuticals, diagnostic equipment and other medical treatments have prolonged life expectancy. However, these interventions can also contribute to environmental contamination. In 2008, the Associated Press reported pharmaceuticals in the water of 24 major metropolitan areas in the United States, serving 41 million people.17 There is a concern that these pharmaceuticals could negatively impact male fertility, lead to birth defects, cause breast and testicular cancer in humans, and lead to antibiotic resistance.18 For many pharmaceuticals found in water sources, no concerted environmental impact surveys have been carried out.19
Mercury is used in fever thermometers, sphygmomanometers, gastrointestinal tubes, and oesophageal dilators20. Reports indicate that medical waste incinerators are among the largest sources of anthropogenic mercury emissions in both the United States and Canada.21 Medical waste, while not the principle source of mercury poisoning, contributes to the mercury levels present in the environment. In fetuses, infants and children, low-dose exposure to mercury can cause severe and lifelong behavioural and cognitive problems.22 At higher exposure levels, mercury may adversely affect the kidneys, the immune, neurological, respiratory, cardiovascular, gastrointestinal, and haematological systems of adults.23 It has also been linked to cancer.24
These examples highlight the major categories of human exposure to chemicals. As the review suggests, some of these chemicals have been linked to harmful human health impacts. What is important to keep in mind, however, is that the harm is conditional on the level and lengths of exposure. For most people, these chemicals pose no harm because the exposure is so low. In some cases, such as BPA, it has been determined that the potential harm is not worth the risk: the Canadian government has decided to declare BPA toxic and regulate it accordingly. In other cases, such as pharmaceuticals, the evidence simply warrants further study and surveillance. Given the potential harm to human health, surveillance and research are vitally important in all categories. The more information that is available to policy makers and health care professionals, the better the chance of limiting human health impacts.
What has been done?
Concerns regarding chemical contamination and human health have led to numerous interventions from the international community. These include the International Programme on Chemical Safety (1980), the Inter-Organization Programme for the Sound Management of Chemicals (1995), the Globally Harmonized System of Classification and Labelling (2002), and the Strategic Approach to International Chemicals Management, which was adopted by governments and stakeholders at the first International Conference on Chemicals held in Dubai in 2006. 25
Various conventions have also been passed, including the Stockholm Convention (2004) on persistent organic pollutants such as DDT, and the Rotterdam Convention (2004) which applies to pesticides and industrial chemicals.26 There is some concern about the continued effectiveness of the Rotterdam convention. In 2006, the Canadian government was instrumental in preventing the listing of asbestos as a toxic chemical. Given the persuasive evidence of the harm caused by asbestos, this action undermines the legitimacy of voluntary international conventions.27
In addition to being a signatory to all international agreements listed above, the Canadian government has programs for chemical management domestically. The main tool is the Canadian Environmental Protection Act (CEPA) 1999. Jointly administered by Environment Canada and Health Canada, it is intended to prevent pollution and address the potentially dangerous chemical substances to which Canadians are exposed.28 The plan calls for increased surveillance of certain chemicals to monitor exposure and health effects, and will increase focus on the management of the health and environmental risks of pharmaceuticals, personal care products, and chemical contamination in food.29
There were 23,000 chemical substances on the Domestic Substances List (DSL) in Canada in 1999. To date, only about 1,000 of these chemicals have been fully assessed. Of the remaining 22,000, 85% have been categorized as not requiring any additional action.30The most recent Canadian Chemicals Management Plan states that full assessments will be done on 550 substances identified as potentially harmful. Even with these additional assessments, more than 3,000 chemicals will not have been assessed.
Canadian Medical Association
In 2009, the Canadian Medical Association and the Canadian Nurses Association released a joint position statement on environmentally responsible activity for the health-care sector. Recommendations included the proper handling and disposal of toxic chemicals and the reduction of products using these substances. An adapted version of this position statement was then endorsed by a coalition of 12 national healthcare organizations and the David Suzuki Foundation.
In October 2010, the World Medical Association, of which CMA is a member, adopted a policy statement on environmental degradation and the management of chemicals. The statement calls for mercury-free health care, support for international efforts to restrict chemical pollution and to monitor harmful chemicals in humans and the environment, and mitigation of the health effects of toxic exposure to chemicals.
What needs to be done?
Research and Surveillance
Research on chemicals produced through man-made activities remains insufficient. While some of the more toxic chemicals have been reviewed and are now more closely regulated, thousands remain that have had neither health nor environmental assessments. The Domestic Substances List in Canada has 3,300 chemicals of concern that have not been assessed. There is limited research on the effect of these chemicals in combination or in different mediums. Finally, work must be done to ensure environmental and human surveillance of potential chemical exposure threats.
1. Urges the government to complete the health and environmental assessment of the chemicals on the Domestic Substances List.
2. Encourages research on the health impacts of chemical substances, as well as the combinations of these substances in different products (e.g. pesticides), and in different mediums (e.g. pharmaceuticals in drinking water). Long-term research programs are required to determine health impacts from prolonged low-dose exposures.
3. Encourages ongoing surveillance of chemicals in the environment.
4. Encourages ongoing research on the impact of regulations and monitoring of chemicals on human health and the environment.
Regulations have been developed both internationally and domestically to undertake chemical management. However, gaps remain, largely due to the voluntary nature of the frameworks. Canada can play a lead role by respecting its commitments, seeking continued adherence to these agreements and providing leadership in developing effective domestic programs and legislation.
5. Urges the government to continue to support international efforts to manage chemical pollution. In particular CMA urges the government to fully support the principles of the Rotterdam Convention and support the listing of Asbestos as an Annex III toxic chemical.
6. Supports government legislation and regulation which reduces dangerous chemical pollution, detects and monitors harmful chemicals in both humans and the environment, mitigates the health effects of toxic exposures, and requires an environmental and health impact assessment prior to the introduction of a new chemical. Regulatory frameworks should be favoured over voluntary frameworks in order to ensure a level playing field for all manufacturers and to secure rapid and equitable health protection for all Canadians. CMA encourages the government to advocate for similar legislation internationally.
Physicians can participate in the monitoring of patients for potential health effects from chemical exposure. Additionally, physicians can be leaders in encouraging greener health care practices. Finally, physicians can support national medical organizations in developing clinical tools to assess patient risk to chemical exposure.
7. Supports the phase out of mercury and other persistent, bio-accumulating and toxic chemicals in health care devices and products.
8. Supports the development of effective and safe systems to collect and dispose of pharmaceuticals that are not consumed.
9. Supports the development of clinical tools for physicians to help assess their patients' risk from chemical exposures.
Education and Professional Development
Physicians have a role to play in educating their patients, the public, and current and future colleagues about the potential human health consequences of chemical contamination. Medical education and continuing professional development in this area could have a significant impact on human health.
10. Should assist in building professional and public awareness of the impact of the environment and global chemical pollutants on personal health.
11. Supports the development of locally appropriate continuing medical education on the clinical signs, diagnosis and treatment of diseases that are introduced into communities as a result of chemical pollution.
12. Encourages physicians to inform patients about the importance of safe disposal of pharmaceuticals that are not consumed.
National and International initiatives have substantially reduced the incidence of harmful chemical contamination, but more work is needed. Evidence of health effects (or lack thereof) may be strong for certain chemicals, but for others it remains incomplete. Given the dangers of chemicals such as dioxin, which can cause severe effects with small doses, more comprehensive research is warranted. To ensure human health consequences are identified and risks are minimized, improved surveillance is essential.
Further policies and regulations are needed to ensure that chemicals utilized are as safe as possible. The Canadian BPA ban demonstrates the use of the precautionary principle in the presence of convincing if not complete evidence. While there are clear benefits associated with the use of chemicals, it is necessary to ensure that potential harmful effects are considered.'
Finally, public and health care provider information is sorely lacking. Physicians can play a role in correcting some of these deficiencies through their actions to support research and surveillance, advocacy, leadership, education, and professional development.
