Canadian Public Health Laboratory Network Core Functions of Canadian Public Health Laboratories Canadian Public Health Laboratory Network The CPHLN Core Functions of Canadian Public Health Laboratories document is based on the white paper, “Core Functions and Capabilities of State Public Health Laboratories,“ published by the Association of Public Health Laboratories (APHL), as well as core functions material produced by the British Columbia Centre for Disease Control, Cadham Provincial Laboratory in Manitoba and the Provincial Laboratory in Saskatchewan. The CPHLN gratefully acknowledges the contribution of the above organizations in the preparation of this document. What is a core function? A core function is a role fundamental to a laboratory’s mandate that identifies the minimum functions that must be supported by adequate capabilities and resources to ensure sufficient capacity or output of services. Background What functions should, and do, Canadian, public health laboratories perform? What capabilities should, and do, they have? What is, and should be, their unique role in safeguarding the public's health? Canada's public health laboratories are an integral component of Canada's public health system. Critically linked to all sectors of the public health infrastructure (e.g. disease control and prevention, environmental health, epidemiology, emergency preparedness and response), public health laboratories provide early detection of health risks associated with infectious agents, compile data in support of outbreak investigations and identify causes of disease to aid in treatment and prevention. As providers of essential services and leadership in the development of programs and policies, Canada's public health laboratories offer the science and resources needed to promote and protect the health of Canadians. In defining the core functions of public health laboratories in Canada, it is important to understand the scope of responsibilities of today's public health laboratory. Far beyond their traditional role of laboratory testing, public health laboratories are now engaged in the broader challenge of disease recognition, prevention and control as well as health improvement. The CPHLN forges a critical partnership that draws together public health laboratories to create a national program-based approach to disease control. CPHLN partnerships are integral components of the "health team." A core function is a role fundamental to a laboratory's mandate. The term capability refers to a specific activity that ensures the laboratory's success in implementing the core function. Each organization also has capacity or, in the case of public health laboratories, output of testing or services provided over a defined period. The Core Functions of Canadian Public Health Laboratories document identifies the minimum core functions of Canadian public health laboratories, which must be supported by adequate capabilities and resources to ensure sufficient capacity or output of services. The CPLHN recognizes that the core functions and capabilities of Canada's public health laboratories reflect the needs, priorities and resources of their respective constituencies, and thus may differ somewhat from region to region. As such, the core functions and capabilities outlined in this document are intended to serve as a frame-work for future evaluation activities as well as investment and policy decisions involving Canada's public health laboratories. The ability of the public health system to respond to emerging public health challenges, such as the advent or outbreak of new diseases, depends on the efficacy of Canada's public health laboratories. To ensure the performance of the public health system in meeting these challenges and protecting the well being of Canadian communities, the functions, capabilities and responsibilities of public health laboratories must be evaluated and updated on an ongoing basis. collaboration Core Functions of Canadian Public Health Laboratories 2 Core Functions and Capabilities The following are ten core functions and capabilities basic to the Canadian public health laboratory system. The CPHLN considers these to be a minimum requirement for the provision of optimal service on behalf of communities throughout Canada. 1. Communicable disease surveillance, prevention and control; 2. Outbreak and emergency response to communicable diseases; 3. Environmental health and food safety; 4. Reference testing, specialized screening and diagnostic testing; 5. Biosafety, containment, and biohazard spill response programs; 6. Integrated communicable disease data management; 7. Public health policy development and evaluation; 8. Laboratory improvement and regulation (Quality Assurance); 9. Training and education of health care and public health workers; and 10. Public health related research and development.

Core Functions of Canadian Public Health Laboratories 8 Core Functions Fulfillment To support the development of the ten core functions and capabilities identified by the CPHLN, Canadian public health laboratories are encouraged to: • Build and strengthen partnerships with provincial/territorial, regional and national public health leaders and private industry; • Maintain communication with medical health officers, epidemiologists and infectious disease experts, as well as environment departments, public health nurses, agriculture departments, and policy makers; • Address legislative and regulatory responsibilities with laboratory stakeholders; • Participate in strategic planning and policy development processes; • Explore ways to optimize resources in a fiscally challenging environment; and • Develop accountabilities within a framework of evaluation for the optimal delivery of public health and reference services. facilitate 9 Core Functions of Canadian Public Health Laboratories leadership Dialogue surrounding core functions and capabilities should not be limited to local public health laboratories. Comprising an integral component of the broader network of Canadian public health, public health laboratories have an opportunity to contribute to the development of a national framework for the delivery of improved public health. Collaboration among federal, provincial, and territorial participants is necessary to balance the strengths and weaknesses in Canada's public health laboratory system and ensure a cohesive response in outbreak and emergency situations.
