Evidence based medicine in primary care: basic concepts and challenges
Evidence-based medicine (EBM) has been defined as ‘the integration of the best research evidence with clinical expertise and patient values’. By enabling clinicians to directly appraise and apply current clinical research, EBM deals with the problems of deterioration in clinical performance, information overload, and lack of application of research findings to clinical practice. EBM is a useful tool to address the problems faced by clinicians attempting to provide optimum, current care for their patients. The rationale for EBM, the principles, application and limitations are described here.
