Analyzing over 325,000 cases at U.S. teaching hospitals between 2018 and 2022, researchers found that racial gaps in endovascular thrombectomy widen alongside stroke severity. Dr. Muhammed Amir Essibayi noted that as clinical urgency increases, access to the procedure becomes less equitable, particularly for Black women. This trend persists even when controlling for medical necessity, suggesting that hospital-level disparities remain a structural failure in urgent neurology.

Beyond individual hospital treatment, regional data from Florida and the U.S. "Stroke Belt" reveal distinct, geography-based hurdles. In rural counties, mortality is tied to travel distance and the isolation of neurointerventional centers. Conversely, urban mortality correlates with racialized economic segregation and structural socioeconomic disadvantage. Dr. Natália Vasconcellos and student researcher Dylan Yates emphasize that a one-size-fits-all policy will fail; rural areas require better transfer networks, while urban centers demand investment in underserved neighborhoods to dismantle the barriers to specialized care.
