This pilot project explores geographic variations in the adoption of stroke treatment technology across hospitals, and the extent to which more rapid adoption in some hospitals may exacerbate health disparities between advantaged and disadvantaged communities. The study focuses on the dissemination of advanced stroke treatment capabilities across hospitals between 2008 and 2019; and how race, ethnicity, income, population density, and geography relate to a patient’s access to different levels of care. The proposed database development and exploratory research will lay the foundation for a larger R01 proposal that we plan to submit subsequently.
