This book is a gateway to an extremely important, but often ignored area of research: the art and science of collecting and pooling information from primary research studies. The aim of systematic reviewing is to arrive at a more comprehensive and trustworthy picture of the topic being studied than is possible from individual pieces of research. This timely, engaging book provides an overview of the nature, logic, diversity and process of undertaking systematic reviews as part of evidence-informed decision making. A short, accessible and technically up-to-date book, it covers the full breadth of approaches to reviews from statistical meta analysis to meta ethnography.The content is divided into five main sections covering approaches to reviewing, getting started, gathering and describing research, appraising and synthesizing data, and making use of reviews and models of research use. As systematic reviews become included in many more graduate-level courses, this book answers the growing demand for a user-friendly guide. It is ideal for anyone undertaking their own systematic review, providing all the necessary conceptual and technical background needed to make a good start on the process.
