Summary
African Americans (AA) received mechanical thrombectomy (MT) for acute ischemic stroke (AIS) less often than non-Hispanic Whites (NHW) and Hispanics. Further research is needed to address this stroke treatment disparity.
Area of Science:
- Neurology
- Public Health
- Health Disparities
Background:
- Racial-ethnic minorities disproportionately experience stroke and receive suboptimal care.
- Mechanical thrombectomy (MT) is a standard treatment for acute ischemic stroke (AIS) with large vessel occlusion (LVO) since 2015.
Purpose of the Study:
- To analyze national trends in MT utilization for AIS patients.
- To investigate racial disparities in MT use.
- To identify factors contributing to these disparities.
Main Methods:
- Retrospective cohort study utilizing the Nationwide Inpatient Sample (NIS) from 2006-2014.
- Analysis of 889,309 AIS cases, including 5,256 MT procedures.
Main Results:
- MT utilization was significantly lower in African Americans (AA) compared to non-Hispanic Whites (NHW) (OR 0.67; 95% CI 0.58-0.76).
- No significant difference in MT utilization was observed between Hispanics and NHW (OR 0.94; 95% CI 0.78-1.13).
Conclusions:
- A significant racial disparity exists in MT utilization for AIS patients, with AA receiving this treatment less frequently.
- Understanding the underlying causes of this disparity is crucial for improving stroke care equity.
