Health, health care and the environment are linked inextricably. Environmental contaminants have been associated with compromised health status, including cancer, birth defects, respiratory and cardiovascular illness, gastrointestinal ailments and death - and an increased demand for a range of health care services.
The health sector is a significant part of Canada's economy, contributing approximately 10% of gross domestic product (GDP). Thus, the sector uses considerable energy, consumes large quantities of plastics, paper and other resources, and produces significant solid, liquid and gaseous waste. With the improvement of health care technologies and a growing awareness of environmentally responsible practices, there is an increased opportunity for reducing the health sector's environmental footprint. Although there are important health, financial and ethical reasons for adopting such practices in the health sector, a number of challenges exist, including financial, technical and administrative challenges.
We envision the health sector as a leader in integrating environmentally responsible practices into the delivery of health care. We also see it as an advocate in sharing information on best practices and encouraging Canadians and Canadian organizations to limit their environmental footprint. In a green health sector, minimizing negative impact on the environment would be a priority for all organizations and individuals in their day-to-day practices and at all levels of decision-making.
A collaborative approach
Achieving our vision requires a collaborative approach to delivering environmentally responsible health care. For example:1
Greener health infrastructure
* support investment in renewing physical plant infrastructure that allows for the retrofit of facilities that function more efficiently, use cleaner technologies and meet new environmental standards for energy efficiency, water management and waste management
* educate staff and the public on the link between health and the environment and on the health impact of environmental degradation, and help in the development, dissemination and implementation of knowledge and best practices
* support and encourage research on health and the environment, and on environmentally responsible practices in a variety of health care settings
* implement energy-conserving techniques and products
* request rationalized packaging and other environmentally responsible actions from vendors of health care products
* promote safer substitutes to reduce exposure to toxic substances
* reduce waste by reusing and recycling when possible
* practise safe disposal practices for biomedical and infectious waste, outdated medications, and polyvinyl plastics, mercury and other toxic substances
* establish green teams to support the practice of ecologic stewardship
We recognize that our efforts to achieve a greener health sector must fit into broader societal and global actions to improve the environment. The health sector plays a role in supporting the efforts of all Canadians to find environmentally responsible ways to perform their daily activities by contributing to the management of global environmental issues, such as greenhouse gas emissions and toxic waste disposal.
Calls to Action
We call on governments and policymakers at all levels to understand and address links between health and the environment and to incorporate these links into policy decisions through legislative and budgetary actions.
We call on all health care organizations to pledge to minimize the negative impact of their activity on the environment and to seek solutions to existing barriers.
We call on individuals working in the health sector to both model and advocate for environmentally responsible approaches to delivering health care without compromising patient safety and care.

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.

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.
