This insightful book describes how Health Services Research (HSR) can be developed and used to evaluate, advance and improve all aspects of health services. It demonstrates the need for good HSR to avoid the continuation or development of ineffective or cost-inefficient services.Drawing on his extensive personal experience in the development of HSR, Walter Holland provides examples from the US and the UK to illustrate important lessons for the future improvement of health services. Taking a distinctive approach to describing the purposes and activities of HSR, the book focuses on the significance of close collaboration with those responsible for the delivery and decisions of health policy. The major message is the importance of heeding the findings of HSR so as to develop evidence-based health policy, and to understand and influence the actions of health professionals, managers and politicians. Holland strongly advocates greater use of HSR and emphasizes its ability to provide vital evidence on how to improve health services.This highly informative and detailed book will strongly appeal to health service researchers, public health practitioners, clinicians, health-service managers, administrators and health policymakers.
