The impact of race and ethnicity on acute telestroke care: A multistate experience

Introduction: Previous analyses suggest that ethnic and racial differences exist in acute stroke care including thrombolytic treatment rates. The current study evaluates ethnic or racial differences in acute stroke treatment within a multi-state telestroke program.

Methods: Acute telestroke consultations seen in the Emergency Department in 203 facilities and 23 states were extracted from the Telecare by TeleSpecialists^TM database. Cases were reviewed for age, race, ethnicity, sex, last known normal time, arrival time, treatment with thrombolytic therapy, door-to-needle (DTN) time, and baseline National Institutes of Health Stroke Scale score. Race was defined as Black, White, or Other; ethnicity was defined as Hispanic or non-Hispanic.

Results: The current study included 13,221 acute telestroke consultations consisting of 9890 White, 2048 Black, and 1283 patients classified as Other. A total of 934 patients were Hispanic and 12,287 patients were non-Hispanic. There were no statistically significant differences noted in thrombolytic treatment rates when comparing White (7.9%) patients with non-White patients (7.4%), p = 0.36, or comparing Black (8.1%) with non-Black patients (7.8%), p = 0.59. In addition, there were no statistically significant differences in treatment rates comparing Hispanic (6.3%) with non-Hispanic (7.9%) patients, p = 0.072. We noted no measurable differences in DTN times by race or ethnicity.

Conclusions: Contrary to previous reports, we failed to detect any significant differences in thrombolytic treatment rates and DTN times by race or ethnicity among stroke patients in a multistate telestroke program. These findings support the hypothesis that telestroke may mitigate racial and ethnic disparities which may be attributable to local variability in stroke procedures or access to healthcare.
