Dissemination and implementation of clinical practice guidelines: a longitudinal, mixed-methods evaluation of the Canadian Task Force on Preventive Health Care's knowledge translation efforts.

Background: The Canadian Task Force on Preventive Health Care (task force) develops evidence-based preventive health care guidelines and knowledge translation (KT) tools to facilitate guideline dissemination and implementation. We aimed to determine practitioners' awareness of task force guidelines and KT tools and explore barriers and facilitators to their use.

Methods: The task force's KT team completed annual evaluations using surveys and interviews with primary care providers in Canada from 2014 to 2020, to assess practitioners' awareness and determinants of use of task force guidelines and tools.
