Research evidence communication for policy-makers: a rapid scoping review on frameworks, guidance and tools, and...

Communication is a multifaceted process, ranging from linear, one-way approaches, such as transmitting a simple message, to continuous exchanges and feedback loops among stakeholders. In particular the COVID-19 pandemic underscored the critical need for timely, effective and credible evidence communication to increase awareness, levels of trust, and evidence uptake in policy and practice. However, whether to improve policy responses in crises or address more commonplace societal challenges, comprehensive guidance on evidence communication to decision-makers in health policies and systems remains limited. Our objective was to identify and systematize the global evidence on frameworks, guidance and tools supporting effective communication of research evidence to facilitate knowledge translation and evidence-informed policy-making processes, while also addressing barriers and facilitators.

We conducted a rapid scoping review following the Joanna Briggs Manual. Literature searches were performed across eight indexed databases and two sources of grey literature, without language or time restrictions. The methodological quality of included studies was assessed, and a narrative-interpretative synthesis was applied to present the findings.

We identified 16 documents presenting either complete frameworks or framework components, including guidance and tools, aimed at supporting evidence communication for policy development. These frameworks outlined strategies, theoretical models, barriers and facilitators, as well as insights into policy-makers' perspectives, communication needs, and preferences. Three primary evidence communication strategies, comprising eleven sub-strategies, emerged: "Health information packaging", "Targeting and tailoring messages to the audience", and "Combined communication strategies". Based on the documented barriers and facilitators at micro, meso and macro levels, critical factors for successful communication of evidence to policy-makers were identified.

Effective communication is indispensable for facilitating knowledge translation and evidence-informed policy-making. Nonetheless gaps persist in frameworks designed to enhance research communication to policy-makers, particularly regarding the effectiveness of multiple communication strategies. To advance in this field, the development of comprehensive frameworks incorporating implementation strategies is warranted. Additionally, barriers and facilitators to implementing effective communication must be recognized and addressed taking diverse contexts into consideration.
