Cochrane Qualitative & Implementation MethodsOur focus is on methods and processes involved in the synthesis of qualitative evidence and the integration of qualitative evidence with Cochrane intervention reviews of effects. Our purpose is to advise Cochrane and its network of people on policy and practice and qualitative evidence synthesis, develop and maintain methodological guidance, and provide training to those undertaking Cochrane reviews. From 2012 our mandate was extended to include methods for undertaking systematic reviews of implementation.
