In a large, nationally representative retrospective cohort study, migraine admission with aura was independently associated with transient ischemic attack (TIA) readmission, and status migrainosus was independently associated with subarachnoid hemorrhage. The Nationwide Readmissions Database was designed to analyze readmissions for all payers and uninsured, with data on more than 14 million US admissions in 2013. Researchers identified index migraine admissions with and without aura or status migrainosus, and readmissions for cerebrovascular events. Cox proportional hazards regression was performed for each outcome with aura and status migrainosus as main predictors, adjusting for age and vascular risk factors. They found:
- Out of 12,448 index admissions for migraine, 9972 (80.1%) were women, mean age was 45.5 ± 14.8 years, aura was present in 3038 (24.41%), and status migrainosus in 1798 (14.44%).
- The 30‐day readmission rate (per 100,000 index admissions) was 154 for ischemic stroke, 86 for TIA, 42 for subarachnoid hemorrhage, and 17 for intracranial hemorrhage.
- In unadjusted models, aura was significantly associated with TIA (hazard ratio 2.43), but not acute ischemic stroke (1.26), intracranial hemorrhage (1.86), or subarachnoid hemorrhage (1.85).
