The Public Health Agency of Canada (PHAC) develops a variety of guidelines that provide advice to policy-makers, public healthcare systems, and Canadians through the support of standing guideline panels, and by providing funding or collaborating with external organizations on ad hoc topics. Topic areas for PHAC guidance include travel medicine, immunizations, influenza prevention, problematic substance use, family violence, dementia, suicide prevention, traumatic head injury/concussions, physical activity, cancer prevention, sexual health, healthcare-acquired infections, and tobacco cessation. | The Public Health Agency of Canada (PHAC) develops a variety of guidelines that provide advice to policy-makers, public healthcare systems, and Canadians through the support of standing guideline panels, and by providing funding or collaborating with external organizations on ad hoc topics.

Background
Clinical and public health guidelines are “systematically developed, evidence-based statements which assist providers, recipients and other stakeholders to make informed decisions about appropriate health interventions.”[1]
The Public Health Agency of Canada (PHAC) develops a variety of guidelines that provide advice to policy-makers, public healthcare systems, and Canadians through the support of standing guideline panels, and by providing funding or collaborating with external organizations on ad hoc topics. Topic areas for PHAC guidance include travel medicine, immunizations, influenza prevention, problematic substance use, family violence, dementia, suicide prevention, traumatic head injury/concussions, physical activity, cancer prevention, sexual health, healthcare-acquired infections, and tobacco cessation.
To maximize their impact, guidelines should be free of conflicts of interest (COI) – situations in which the judgment of an individual involved in developing a guideline is unduly influenced (or seen to be unduly influenced) by a secondary interest (such as the opportunity to derive personal benefit).[1]
Given several high-profile news stories within and outside Canada,[2][3][4][5][6][7][8][9][10] the health community that benefits from evidence-based guidance and policy, and Canadians more generally, are increasingly aware of the importance of disclosing and managing COI in guidelines. These examples demonstrate the considerable reputational and other risks that poorly managed COI in the context of guidelines could pose to PHAC and its partners. Beyond that, proper management of COI is an established criterion for assessing guideline quality.[11]
PHAC has taken steps towards addressing the issue of COI in guideline development by hosting a Best Brains Exchange on the topic[12] in collaboration with CIHR. This meeting, which took place in January 2019, brought together over 60 participants representing academia, guideline producing groups from Canada and internationally, journal editors, and federal and provincial governments.
The principles put forward by the Guidelines International Network (GIN) are a key guiding document for improving the management of COI within guideline development, and were discussed extensively at the BBE.[12][13] The GIN principles provide a framework for consistent and appropriate management of COI in guideline development.[13] While there was broad agreement that implementation of these principles would improve COI management in Canadian guidelines, it was felt by many that support would be needed to fully implement these principles across various groups.
Overall, one clear theme emerged from the BBE: The need for national leadership, national standards, national approaches, and national transparency to help bring Canada up to the level of COI management seen in other countries.[12] A report summarizing the BBE presentations and discussions is available in both official languages using the following links:
Shortly after the BBE, the Canadian Medical Association Journal, one of the foremost publishers of guidelines in Canada, announced that as of 2020, all groups publishing guidelines in their journal must adhere to the GIN principles.[14] Therefore it is anticipated that a key area for national leadership in this area will be to help Canadian guideline producers (within PHAC or external) in adhering to the GIN principles, and generally implementing best practices related to COI. For some groups, this may require only small shifts in their current policies and procedures, while for other groups (e.g., smaller or with less resources) this could require considerable work.
PHAC, through its Guidance Innovation Hub has developed a compendium of tools, listed on this page, that can be used by national guideline development groups to help improve their practices related to the management of COI, including adherence to the GIN principles.
PHAC Disclosure of Interests Form and COI Assessment Tool
- PHAC Dislosure of Interest Form (last updated Sept 11, 2020)
- PHAC COI Assessment Tool (last updated April 16, 2021)
Implementing the Guidelines International Network (GIN) Principles
Following the BBE, PHAC's Guidance Innovation Hub, along with BBE organizers and participants, developed practical guidance and tools for implementing the GIN principles, based on a scan of international best practices, informal interviews with guideline developers, and the experiences of the authors. This includes a checklist to aid journals seeking to implement the GIN principles on COI for authors, or guideline developers assessing or updating their policies to align with the GIN principles.
The article is published in CMAJ and is available in English and French.
