Cognitive Bias in the Patient Encounter: Part I. Background and significance

Christine J Ko et al. J Am Acad Dermatol. .

Abstract

Cognitive bias may lead to diagnostic error in the patient encounter. There are hundreds of different cognitive biases, but certain biases are more likely to affect patient diagnosis and management. As during morbidity and mortality rounds, retrospective evaluation of a given case, with comparison to an optimal diagnosis, can pinpoint errors in judgment and decision-making. The study of cognitive bias also illuminates how we might improve the diagnostic process. In Part 1 of this series, cognitive bias is defined and placed within the background of dual process theory, emotion, heuristics, and the more neutral term judgment and decision-making bias.

Keywords: Cognitive bias; JDM bias; bias; decision-making; diagnostic error; heuristic; metacognition; patient safety.
