Essential Public Health is the second edition to the widely acclaimed and best-selling Essential Public Medicine. The latter became a standard text in very many institutions of learning and training as well as being read by students and practitioners across a wide range of disciplines. Throughout its 17 years of existence, it has been in constant demand. Essential Public Medicine builds upon this successful formula but has been fundamentally revised and recast. It describes the whole spectrum of public health: the principles, methods and applications of epidemiology, the assessment of health and health need in populations, the promotion of health and prevention of ill-health, the planning and evaluation of health services, the monitoring of disease trends, outbreaks and environmental hazards, the investigation of health and health service problems.This book is essential reading for all students of public health, as well as students of medicine, nursing and health visiting, where public health is such an important part of a modern curriculum. Those involved in courses of postgraduate study, particularly those in public health, will find it of value. It will be a source of knowledge and information for those from a variety of different disciplines who are embarking on a career in public health. It will also be a useful resource for established practitioners - public health doctors, senior nurses, general practitioners, health visitors - who wish to consolidate or update their knowledge. Increasingly, public health is of relevance to the work of managers, health care policy makers and students whose courses contain modules on health and public sector issues. The book, therefore, will also be of value to health service managers, non-executive members of health authorities. NHS Trust Boards and the Board of Primary Care Trusts, as well as students in the policy field and in social sciences.
