PHAC Conflict of Interest Toolkit for Guideline Development

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.”

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).

Given several high-profile news stories within and outside Canada, 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.

PHAC has taken steps towards addressing the issue of COI in guideline development by hosting a Best Brains Exchange on the topic 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. The GIN principles provide a framework for consistent and appropriate management of COI in guideline development. 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.

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. 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 COI assessment tool for guideline development

There is an important distinction to make between disclosed interests, and the presence of COI. Expert advisory panelists providing advice to PHAC or otherwise developing guidance (e.g., clinical practice guidelines) may have a wide variety of affiliations and interests. As noted by the World Health Organization, "The declaration of one or more secondary interests (declaration of interests) does not automatically mean that a conflict of interest is present: there is a distinction between the two. A transparent and objective process for assessing a declaration of interests is required to determine if a conflict exists and what its effects might be, and to manage any significant conflict of interest." Figure 1 provides an overview of the link between disclosures of interests, and the identification and management of COI.

Figure 1. An overview of processes involved in the disclosure and assessment of interests, and identification and management of COI

Individuals involved with guidance development panels (within PHAC, Health Canada, or otherwise) are regularly collecting disclosures of interests from their panel members. Groups have expressed challenges in determining if COI is present and how to best manage COI. A variety of approaches are currently being used to determine COI and associated management options, and approaches are not always well documented, leading to concerns about consistency and transparency.

PHAC therefore sought to develop a structured COI assessment tool that can:

• Aid the processes of COI management for groups that work with external bodies of experts
• Be used to consistently and transparently evaluate disclosed interests for the presence of COI, and determine the ideal management approach
• Be flexible and adaptable enough to fit the needs of a variety of groups in different contexts

This tool was informed by an environmental scan of factors used to assess for the presence of COI, as well as approaches to COI management, among the international guideline community. Factors commonly considered in assessing for COI include:

• Relevancy/specificity to the topic
• Recency/currency
• Frequency of the interest/relationship
• Duration and depth of the relationship
• Amount (for financial interests)
• The role of the individual in the guideline process/decision-making

The PHAC tool allows for a structured and transparent assessment of the above factors, to allow the assessor to come to a final judgment about the presence of COI. Use of the tool involves the following steps:

1. Interests are disclosed by the expert in the DOI form (see PHAC COI disclosure form for guideline development)
2. Info disclosed in forms by experts are input into the tool by the assessor
3. Assessor makes a judgment on relevancy and other key considerations
4. Based on those factors, a judgment is made on the presence (yes/no) and type of COI (financial, non-financial) and how significant the COI is (low, moderate, high), with the aid of a rubric/algorithm

Figure 2 provides a conceptual schematic of the tool. Detailed instructions for assessing each factor and making judgments on the type and significance of COI are included in the tool.

Figure 2. Conceptual schematic of the PHAC COI assessment tool. Information that will be disclosed in the PHAC disclosure of interest form are in red. Other considerations could, for example, be whether a published article was based on opinion versus simply restating published evidence. It could also be, for example, if an honorarium or grant was paid to the individual’s institution versus directly to them.

As noted in Figure 1, when COIs are deemed to be present, the next step is management of those COIs. To facilitate consistent and transparent approaches to managing COI, an algorithm has been developed (Figure 3)to help guide assessors to suggested management options taking into account:

• The type of COI (direct/indirect financial, non-financial)
• The severity of COI (low, moderate high)
• Internationally recognized principles for the management of COI (e.g., GIN)

This algorithm to guide users on how to manage COI is included in the COI assessment tool, along with detailed instructions for users.

Figure 3. Algorithm for determining management options for COI. The management options provided herein are suggestions that take into account international standards such as the GIN principles, and can be modified to suit the individual needs of each guideline group. Where multiple options are presented, the choice may depend on the number of COI identified, the presence of COI among other panelists involved in a guideline, and how strict a stance the group wishes to take on COI.

The full COI assessment tool is currently undergoing pilot testing, and a final tool will be uploaded soon.

Guidelines International Network (GIN) Checklist

The following checklist was developed by PHAC 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.

A document or link to the document will be uploaded soon.
