How common are cognitive errors in cases presented at emergency medicine resident morbidity and mortality conferences?

Chu D, Xiao J, Shah P, Todd B. Diagnosis (Berl). 2018 Jun 20; [Epub ahead of print].

This retrospective review of cases presented at one hospital's emergency medicine morbidity and mortality (M&M) conferences found that more than half involved a diagnostic error, most of which were a cognitive error. When present, cognitive errors were more frequently ascribed to faulty data synthesis rather than a knowledge deficit.
