This work is a useful resource that covers the process of research synthesis for the purpose of evidence based healthcare improvement. Williamson et al. integrate the conceptual and procedural dimensions of research synthesis in each of the five stages of the process to produce step-by-step instructions for clinically applicable research syntheses. The book includes a compendium of Internet sources and addresses as well as several blank forms that serve as checklists and for the recording of important information. Medical specialists and researchers, graduate students, and those who write health science articles for the lay public will find this an invaluable resource for conducting healthcare research syntheses.
