Diagnostic Errors and the Bedside Clinical Examination.

Abstract

Diagnostic errors are common in clinical practice and lead to adverse patient outcomes. Systematic reviews have shown that inadequate history taking and physical examination lead to a plurality, if not a majority, of diagnostic errors. Recent advances in cognitive science have also shown that unconscious biases likely contribute to many diagnostic errors. Research into diagnostic error has been hampered by methodologic inconsistency and a paucity of studies in real-world clinical settings. The best evidence indicates that educational interventions to reduce diagnostic error should give physicians feedback about clinical outcomes and enhance their ability to recognize signs and symptoms of specific diseases at the bedside.
