Every year a vast number of research studies and a myriad of other forms of 'evidence' are produced that have potential to inform policy and practice. Synthesis provides a way of bringing together diverse kinds of evidence to bridge the so called 'gap' between evidence and policy. This book provides a comprehensive overview of the range of approaches and methods available for synthesising qualitative and quantitative evidence and a detailed explanation of why this is important.It does this by: looking at the different types of review and examining the place of synthesis in reviews for policy and management decision making; describing the process of conducting and interpreting syntheses; and, suggesting questions which can be used to assess the quality of a synthesis. ''Synthesising Qualitative and Quantitative Health Evidence'' is essential reading for students and professional researchers who need to assemble and synthesise findings and insights from multiple sources. It is also relevant to policy makers and practitioners in the field of health, and those working in other areas of social and public policy.
