> Evidence-based medicine helps physicians appraise the latest and best evidence and incorporate patient's values in reaching a shared clinical decision. However, many decisions in medicine are made in the paucity of best evidence. Medical uncertainty remains inherent in clinical practice and contributes to significant variability in the way physicians and patients manage medical problems. Physicians and patients have varying degrees of tolerance for uncertainty. Intolerance to uncertainty among physicians results in increased test ordering tendencies, variability in medical treatment, failure to comply with evidence-based guidelines, and even guide career choices. Factors that result in the variability of physicians' interpretation of an effective treatment include: patient factors (prioritizing some factors over others), physician factors (lack of knowledge, lack of resources, medical uncertainty), and environmental factors (limitation of time and practice). Several appro!
aches that have been found useful in implementing evidence in clinical practice include: sending reminders to prompt physicians to perform patient-related clinical activities, introducing computer information systems to support practice, and using interactive education interventions to teach newer skills and challenge negative attitudes. Passive educational approaches, like dissemination of guidelines and didactic lectures, are usually less useful in changing behavior. Among the techniques found to be useful for managing uncertainty are shared decision making, meticulous history taking, and physical examination, excluding worrisome differential diagnosis and establishing trust in patients. The role of future studies in assessing the outcome of multiple evidence-based strategies in situations of medical uncertainty remains to be explored.
