Visual perception, cognition, and error in dermatologic diagnosis: Diagnosis and error

Abstract

Diagnostic error in dermatology is a large practice gap that has received little attention. Diagnosis in dermatology relies heavily on a heuristic approach that is responsible for our perception of clinical findings. To improve our diagnostic accuracy, a better understanding of the strengths and limitations of heuristics (cognitive shortcuts) used in dermatology is essential. Numerous methods have been proposed to improve diagnostic accuracy, including brain training, reducing cognitive load, and getting feedback and second opinions. Becoming comfortable with the uncertainty intrinsic to medicine is essential. Ultimately, the practice of metacognition, or thinking about how we think, can offer corrective insights to improve accuracy in diagnosis.

Keywords: cognitive error; diagnostic error; heuristic; metacognition; patient safety; visual intelligence.
