Extended Window for Thrombectomy – Have we extended our resources appropriately and effectively

Study will evaluate the performance of the RAPID software interpretation of CT perfusion (CTP) studies and determination of qualifications for endovascular therapy (EST). It will include a retrospective case review of prospectively collected data on consecutive stroke patients seen during the extended window for EST and screened with CTP in 2019 and 2020. It will also determine the rate of EST among those screened for the extended window and the rate of favorable 90-day functional outcome (defined as mRS 0-2) among those treated with EST. It will include a retrospective cohort study of prospectively collected data on consecutive Kaiser Permanente patients screened during the EW by telestroke neurologists in the Stroke EXPRESS program and who underwent EST.
