Introduction: Evidence syntheses can be used to inform public health policy and programming decisions, however, organizations may lack the resources and expertise to develop timely, high-quality syntheses. The National Collaborating Centre for Methods and Tools (NCCMT) launched a Rapid Evidence Service (RES) to answer priority public health questions through rapid reviews. The NCCMT also established the Repository of Public Health Evidence Syntheses (the Repository) to minimize duplication of efforts, facilitate collaboration, and ensure public health practitioners have access to relevant evidence syntheses.

Description: The RES process involves collaboratively developing a research question, conducting a comprehensive search, and critically appraising and synthesizing the findings into an actionable report. Each RES report is included in the Repository and made available to the public health community. Other organizations also contribute their syntheses to the Repository. Users can search the Repository for existing syntheses and adapt the findings for use in their own communities or connect with authors to collaboratively address public health issues.

Outcomes: Since launching in 2020, the RES and Repository have focused on many timely public health topics, such as COVID-19, climate change, and health equity. The RES has collaborated with over 20 organizations to complete more than 100 reviews and review updates on 61 topics. The Repository hosts over 600 submissions from over 75 organizations and has been accessed over 30,000 times.

Discussion: The RES and Repository facilitate access to relevant, high-quality evidence syntheses. These services promote the use of synthesized evidence, encourage interorganizational collaboration and ease knowledge exchange in public health decision making.
