Merkler AE, et al. - Using administrative claims from two complementary patient data sets, a retrospective cohort study was performed to determine the long-term risk of seizures after stroke according to age, sex, race, and stroke subtype. From 2005 to 2013, data were analyzed from all emergency department visits and hospitalizations in California, Florida, and New York. From a nationally representative 5% random sample of Medicare beneficiaries, inpatient and outpatient claims were evaluated. They used Poisson regression and demographic data to calculate age-, sex-, and race-standardized incidence rate ratios (IRR). It was observed in the findings that nearly 10% of patients with stroke will develop seizures within 10 years. Findings revealed that hemorrhagic stroke, nonwhite race, and younger age appear to be associated with the greatest risk of developing seizures.
