Patient management is the central clinical task of medical care. Until the 1970s, there was no generally accepted method of ensuring a scientific, critical approach to clinical decision making. And while traditional clinical authority was under attack, there was increasing concern about the way in which doctors made decisions about patient care. In this book, Jeanne Daly traces the origins, essential features, and achievements of evidence-based medicine and clinical epidemiology over the past few decades. Drawing largely on interviews with key players, she offers unique insights into the ways that practitioners of evidence-based medicine set out to generate scientific knowledge about patient care and how, in the process, they reshaped the way medicine is practiced and administered.
