To describe the epidemiology of U.S. emergency department (ED) visits for transient ischemic attack (TIA) and to measure rates antiplatelet medication use, neuroimaging, hospitalization during a ten-year time period.The authors obtained data from 1992-2001 National Hospital Ambulatory Medical Care Survey. TIA cases were identified by having ICD-9 code 435.From 1992 2001, there 769 cases, representing 2,969,000 ED TIA. The population rate 1.1 per 1,000 (95% CI = 0.92 1.30) was stable over time. diagnosed in 0.3% all visits. Physicians administered aspirin other agents small percentage patients, 42% patients 29% 55%) received no medications at ED. Too few points existed statistically valid trend performed computed tomography scanning 56% 45% 66%) magnetic resonance imaging (MRI) < 5% toward increased Admission did not increase period, with 54% 67%) admitted. Regional differences noted, however, highest admission found Northeast (68%).Between stable, as (54%). Antiplatelet appear be underutilized discordant published guidelines. Neuroimaging significantly. These findings may reflect limited evidence base guidelines, educational deficits, or barriers guideline implementation.
