Summary

Hospital encounters before stroke are common but poorly understood. This Australian study of 1,240 first-ever stroke patients finds that patients experiencing hospital care in the prior 90 days were linked to more than double the stroke risk. Common diagnoses included nonspecific symptoms, circulatory disorders, and injuries. These results suggest targets for reducing misdiagnosis to improve primary stroke prevention.
