The evidence-based medicine movement has been one of the most important influences on medicine in the latter half of the 1990s. This textbook on evidence-based decision-making--basing clinical decisions on the best available evidence from systematic research--is ideal for healthcare, medical, and nurse managers. It explains how evidence-based decision making can be applied to health policy and management decisions about groups of patients and populations, rather than decisions about the treatment of individuals. Its first edition was well reviewed and highly successful, and this new edition builds upon the success of the first.
