Missed diagnosis of stroke in the emergency department: a cross-sectional analysis of a large population-based sample.

Newman-Toker DE; Moy E; Valente E; Coffey R; Hines AL.

This observational study identified patients who visited the emergency department within 30 days prior to a stroke diagnosis. Nearly 13% of patients had a potential missed diagnosis, and more than 1% had a probable missed diagnosis of stroke. This study illustrates a novel approach to characterizing the incidence of missed diagnosis, an important and understudied patient safety problem.
