Learn to plan, conduct, or update a systematic review of qualitative evidence Qualitative Evidence Syntheses (QESs) are an increasingly important type of systematic review and a valuable tool for global and local decision-making. Their value as a method for systematically bringing together, assessing and synthesizing qualitative research has made them a crucial part of the industry-standard Cochrane and Campbell Reviews. There is an urgent and as-of-yet unmet need for a QES handbook which equips Cochrane and Campbell review authors with the most appropriate tools, processes, and methods required to conduct robust and trusted QESs. The Cochrane-Campbell Handbook for Qualitative Evidence Synthesis meets this need with a comprehensive, step-by-step guide to conducting Cochrane and Campbell-standard QES. Informed by the knowledge and experience of the Cochrane Qualitative and Implementation Methods Group (QIMG) and members of the Campbell Methods Group, the Cochrane-Campbell Handbook arms review authors with everything they need to conduct qualitative evidence syntheses. The Handbook includes new guidance and evidence-informed tools that make a critical contribution to the ever more important field of evidence synthesis.
