Abstract
This systematic review protocol is developed with the objective to identify the strategies, facilitators, and barriers to interaction between researchers and policy makers to use research evidence in health policy making. It seems that review of interactive methods between researchers and policy makers can help to understand the role of researchers on evidence-informed policy making. Moreover, identifying barriers and facilitators of these interactions can help universities and institutions associated to health policy making in planning to improve the interaction between researchers and policy makers to facilitate evidence-informed policy making.
