Abstract TP316: Urban Crural Comparisons of Treatments and Outcomes for Ischemic Cerebrovascular Diseases

Background: Little is known about healthcare quality and patient outcomes of ischemic cerebrovascular diseases between urban and rural areas in China during the past decade. Methods: We used a two-stage random sampling method to create a nationally representative sample of patients in China hospitalized for ischemic stroke (IS)/ Transient ischemic attack (TIA) in 2005, 2010, and 2015. Firstly, we used simple random sampling to obtain a list of participating hospitals in 2 urban and 3 rural strata. Secondly, we obtained medical records at each hospital on clinical profiles, tests, treatments and outcomes using a systematic sampling approach. We weighted our findings to explore rural-urban disparities from 2005 to 2015. Results: A total of 30 827 patients were sampled from 189 hospitals with 14 418 (46.8%) from urban and 16 409 (53.2%) from rural. We observed a decreased disparity between urban and rural in eligible patients receiving antiplatelet and anticoagulant for atrial fibrillation (AF) (both P trend trend trend trend Conclusion: Although urban-rural disparities in evidence-based treatments for IS/TIA patients have largely been eliminated, substantial gaps in quality of care persist in both settings.
