Association between primary care physician diagnostic knowledge and death, hospitalisation and emergency department visits following an outpatient visit at risk for diagnostic error: a retrospective cohort study using medicare claims.

Gray BM, Vandergrift JL, McCoy RG, et al. BMJ Open. 2021;11(4):e041817.

Ambulatory and primary care are high risk settings for diagnostic errors. This retrospective study examined internal medicine physicians’ performance on diagnostic questions on board certification exams and found that higher diagnostic knowledge was associated with lower risk of adverse outcomes after patient visits for conditions sensitive to diagnostic error (e.g., stroke, pneumonia, pulmonary embolism).
