The importance of epidemiology is being increasingly realised by healthcare practitioners who, traditionally, have focused their attention on the individual rather than populations. The development of successful multidisciplinary practice requires modern healthcare professionals to be flexible enough to absorb ideas from other disciplines, whilst retaining the ability to challenge concepts inconsistent with good practice. This book explores epidemiology, its knowledge base, ideology and practice. Topics covered include: * Essential principles, concepts and research designs in epidemiology * The developing relationship between epidemiology and nursing * A critical appraisal of disease, illness, sickness and health * Healthcare statistics and their political and social dimensions * Epidemiology and healthcare planning * The application of epidemiology in nursing practice * Research evaluation and utilisation: the role of epidemiology
