Health systems everywhere are experiencing rapid change in response to new threats to health, which include lifestyle diseases, risks of pandemic flu, and the global effects of climate change. At the same time, health inequalities continue to widen despite efforts to halt and reverse them. Such developments have profound implications for the future direction of public health policy and practice. This book offers a wide-ranging, provocative, and accessible assessment of challenges confronting a public health system in the UK, exploring how its parameters have shifted over time and identifying the origins of long-standing dilemmas in public health practice. The book provides an overarching review of the state of public health system, and it is based on an extensive literature review and research. It includes historical policy and practice, and it focuses on key issues facing UK public health services, such as management, commissioning, workforce development, and public engagement.
