ED misdiagnosis of cerebrovascular events in the era of modern neuroimaging: a meta-analysis.

Tarnutzer AA, Lee S-H, Robinson KA, et al. Neurology. 2017;88:1468-1477.

Delayed diagnosis of stroke can lead to preventable disability. This meta-analysis of diagnostic accuracy for cerebrovascular events in the emergency department found that overall 9% of strokes were misdiagnosed. The risk of misdiagnosis was higher if stroke symptoms were transient, nonspecific, or mild. The authors suggest that interventions to improve stroke diagnosis should focus on these specific disease presentations.
