Renee Hsia, MD, MSc, FACEP
Renee Y. Hsia, M.D., M.Sc., FACEP is Professor of Emergency Medicine, Health Policy at the University of California San Francisco (UCSF). Her principal interest is the study of health systems to improve the access and delivery of timely acute care for patients, with a particular emphasis on vulnerable populations. Her work has centered around closures of emergency services (including trauma services) in California and nationally, and the effects of closures on patient outcomes for time-sensitive illnesses. Dr. Hsia also analyzes issues of ED utilization across different insurance groups, and ED crowding (using measures such as ambulance diversion and length of stay) and its association with poorer patient outcomes.
Dr. Hsia is also part of the UCSF Center for Healthcare Value, in the section on Price Transparency, with research focusing on the wide variation of prices and lack of price transparency for healthcare in the United States.
Her research extends globally, specifically regarding cost-effectiveness of emergency care in developing countries. She is currently involved in the Disease Control Priorities project with a focus on pre-hospital care. Dr. Hsia has had clinical and public health experience in numerous countries in Africa, including Rwanda, Uganda, Eritrea, Sudan, South Africa, Senegal, and South Sudan. She is fluent in Mandarin, Cantonese, French, and Spanish, and is a member of the UCSF Global Health Economics Consortium and the Global Health Steering Committee for the UCSF Department of Emergency Medicine.
Dr. Hsia’s work has been published in high-impact journals, including JAMA, Health Affairs, Medical Care, Health Services Research, Archives of Internal Medicine, Annals of Emergency Medicine, and the American Journal of Public Health. Her research has been featured nationally in print media (New York Times, Washington Post, USA Today), radio, and network television. Her work has been funded by the National Institute of Health, Robert Wood Johnson Foundation, Agency for Healthcare Research and Quality, American Heart Association, and Emergency Medicine Foundation.
