- Evidence-based medicine (EBM) emerges from the belief that delivery of care to patients will be more effective and efficient if decisions are based, as much as possible, on unbiased robust evidence regarding prognosis, etiology, diagnosis, and therapy/prevention. Although acknowledging a degree of uncertainty in every clinical decision, EBM has always challenged practitioners to pursue evidence to reduce uncertainty as much as possible. Application of only the most rigorous evidence can minimize the uncertainly inherent in medical decisions.
- The promise implicit in an evidence-based approach to patient care, that is, the potential for improved patient outcomes at a reduced cost and for shared decision making with a well-informed patient, has led to an increased adoption of the principles of evidence-based medicine (EBM) worldwide. EBM is increasingly used by individual practitioners wishing to be better informed about clinical problems arising daily from clinical practice.1,2 Payers, providers, and integrated health care delivery systems are increasingly using EBM principles to help determine the most efficient use of health care resources to achieve optimal patient outcomes.
