Interventions at the population level
Many interventions at the individual level must be supported by actions at the community level. Physicians will be expected to advocate for community-wide interventions and address issues that occur to many patients across their practice.
Understand the three levels of prevention: primary, secondary, and tertiary
Describe strategies for community needs assessments, health education, community engagement, and health promotion
Appreciate the role that physicians can play in promoting health, managing risk factors, and preventing diseases at the individual and community level (e.g., reducing injury, immunization, obesity prevention, smoking cessation, cancer prevention)
Understand how public policy can influence population-wide patterns of behaviour and affect the health of a population
Define the levels of prevention in an individual (clinical) and in a population as well as formulate preventive measures to include in clinical management strategies
Name and describe the common methods of health protection (e.g., agent–host–environment approach for communicable diseases, source–path–receiver approach for occupational and environmental health)
Describe the importance and impact of effective, culturally appropriate communication with the patient, the patient’s family and, if necessary, the community as a whole regarding risk factors and their modification
Apply the principles of screening, evaluate the utility of a proposed screening intervention, and be able to discuss the potential for lead-time bias and length-prevalence bias
Understand the importance of disease surveillance in maintaining population health and be aware of approaches to surveillance
Identify ethical issues in restricting individual freedoms and rights for the benefit of the population (e.g., restricting movements of a person with active tuberculosis)
Describe the advantages and disadvantages of identifying and treating individuals versus implementing population-level approaches to prevention
Describe the application of health promotion in a particular situation to help people increase control of their health and improve it
Describe one or more models of behaviour change, including predisposing, enabling, and reinforcing factors
Identify the potential community, social, physical, and environmental factors and work practices that might promote healthy behaviours, as well as identify ways to assist communities and others to support these factors and practices
Be aware of the role of community and social service agencies (e.g., schools, governments, municipalities, nongovernmental organizations) and work collaboratively with them
Demonstrate awareness of the importance and contribution of other allied health professionals (both regulated and unregulated) in addressing population health issues
Be able to describe the health impact of community-level interventions to promote health and prevent disease
Describe examples of public policies that have had a positive effect on population health
