The systematic review of the literature: a tool for evidence-based policy. 
The systematic review of the literature is a valuable tool for gerontological nurses to influence policy decisions.  There are several organizations that provide helpful guidelines for the conduct of systematic reviews of the literature, including the Cochrane Collaboration, the Joanna Briggs Institute, and the Evidence for Policy and Practice Information Co-Ordinating Centre at the Institute of Education, University of London.  Gerontological nurses who have a strong foundation in research methodology and the skills to synthesize scientific evidence for the purpose of promoting evidence-based policy have the potential to positively influence health care outcomes for older adults.  For nurses to assume a leadership role in synthesizing scientific evidence for evidence-based policy development and refinement, nursing education will need to assume a more active role in teaching systematic review methodology.  This article presents an overview of resources for con-ducting systematic reviews of the literature and discusses the use of the systematic review as a tool for evidence-based policy.
