Knowledge brokering — when used in the right situation (where a needs is addressed in a way that complements user practices and environments), it can enhance the overall perception and specific practice of the use of research-based evidence in decision-making.

“Exchange” represents one form of knowledge translation. It often involves the establishment of partnerships between researchers and public policy makers (knowledge users) who are committed to asking and answering relevant questions together.

“Friendly front ends” represent one form of knowledge translation. Research is synthesized and presented in knowledge user friendly formats (e.g., 1 page of take-home messages, a 3-page executive summary, and a 25-page full report). Notifications about, and circulation of these materials can facilitate “user pull” — helping potential knowledge users to become aware of available and applicable research.

“Push” represents one form of knowledge translation. It involves researchers (or intermediary groups) bringing research evidence to the attention of public policy makers (or those who seek to influence them) — knowledge users — and can inform policy development and policy implementation processes.

“User pull” represents one form of knowledge translation. It involves ways of making it easier for public policy makers (knowledge users) to identify relevant research evidence. Knowledge users may formalize the pull process (e.g., the establishment of a receptor function — a formal and proactive process to seek and receive relevant new research; a one-stop shop; self-assessment tools.
