Racial/Ethnic Disparities in Acute Ischemic Stroke Treatment Within a Telestroke Network

Background: The growth of telestroke services expanded the reach of acute stroke treatment. However, ethnic disparities in receiving such treatment have not been fully assessed. Materials and Methods: We reviewed prospectively maintained data on patients evaluated through the Medical University of South Carolina telestroke program between January 2016 and November 2018. Outcomes included odds of receiving intravenous recombinant tissue plasminogen activator (tPA), receiving mechanical thrombectomy (MT), and achieving door-to-needle (DTN) time ≤60 and ≤45 min among patients receiving tPA. We used logistic regression to analyze the contribution of race/ethnicity. Results: We included 2,977 patients, of whom 1,093 (36.7%) identified as nonwhite; of these, 1,048 patients (95.9%) identified as black or African American. Significantly more nonwhite patients were seen at a primary stroke center (PSC) (68.4% vs. 52.3% in whites, p
