This series of 18 articles describes processes for ensuring that relevant research is identified, appraised and used to inform decisions about health policies and programs. The tools were written for people responsible for health policy decision-making (e.g., health system managers and policy-makers) and for those who support them.

CHSRF worked in partnership with the SUPPORT Project to bring you the French version of this series. SUPPORT is an international collaboration network that provides training and support to encourage researchers and policy-makers in collaborative policy-relevant research.

A book version of SUPPORT Tools for evidence-informed health Policymaking (STP) is also available.

Abstract

Systematic reviews are increasingly seen as a key source of information in policymaking, particularly in terms of assisting with descriptions of the impacts of options. Relative to single studies they offer a number of advantages related to understanding impacts and are also seen as a key source of information for clarifying problems and providing complementary perspectives on options. Systematic reviews can be undertaken to place problems in comparative perspective and to describe the likely harms of an option. They also assist with understanding the meanings that individuals or groups attach to a problem, how and why options work, and stakeholder views and experiences related to particular options.

A number of constraints have hindered the wider use of systematic reviews in policymaking. These include a lack of awareness of their value and a mismatch between the terms employed by policymakers, when attempting to retrieve systematic reviews, and the terms used by the original authors of those reviews. Mismatches between the types of information that policymakers are seeking, and the way in which authors fail to highlight (or make obvious) such information within systematic reviews have also proved problematic.

In this article, we suggest three questions that can be used to guide those searching for systematic reviews, particularly reviews about the impacts of options being considered. These are:

  1. Is a systematic review really what is needed?
  2. What databases and search strategies can be used to find relevant systematic reviews?
  3. What alternatives are available when no relevant review can be found?
