Evidence-based practice in primary care: past, present and future

As in other health care specialities, evidence-based practice is beginning to have an impact on the philosophy and workings of primary care. Some practising clinicians, however, may wish to question its relevance to their everyday work, and whether general practitioners and other members of the primary health care team can realistically adopt a new approach to clinical decision making, at a time of such high workload and competing priorities. Major changes have taken place during the last 20 years as a result of the National Health Service (NHS) reforms, the development of general practice and primary care research, and other health service innovations such as the introduction of new technologies, which have had an important impact on primary care. Issues such as the availability and use of different research methods, the role of experts, and the development of guidelines, audit and evaluation of care, are becoming subject to renewed scrutiny. Within this context, this article explores the potential of an evidence-based approach in the primary care setting, and discusses possible strategies for change to assist the dissemination of research into practice and the implementation of evidence-based health care.
