Suolang D, Chen BJ, Wang NY, et al. - Researchers sought to describe the temporal trend in racial and ethnic disparities in stroke IV thrombolysis use between 2009 and 2018 in a representative sample of US adults.

• A total of 935,720 adult hospital discharges with a primary diagnosis of ischemic stroke were identified; 752,369 of these were included in this work (> 97% of excluded observations were due to interhospital transfers, elective admissions, or missing data [5.8% was for race and ethnicity]).

• Between 2009 and 2018, there appeared an improvement in racial and ethnic disparities in IV thrombolysis use after stroke.

• The gap with White individuals narrowed for Black individuals and disappeared for Hispanic individuals.

• Effectiveness of efforts to lower stroke disparities and the increasing organization of stroke care appeared to be the potential reasons for the same.
