Associate Professor of Emergency Medicine

Adherence of ED management and practices to ACEP, CDC, or other guidance, Cost-effectiveness of ED-based HIV testing program using agent-based modeling approach, Epidemiology of non-infectious diseases in ED or disaster settings, Infectious diseases epidemiology (Trends, Risk Factors, Prevention, and Outcomes) in ED settings and ED management of patients with infectious diseases

Dr. Hsieh is the epidemiologist/statistician in the Department of Emergency Medicine with whom we work closely on other projects. Dr. Hsieh also translates his skills to focused studies in acute aspects of HIV, STIs and other infectious diseases which are commonly presented to acute care settings. Dr. Hsieh and his colleagues built and implemented an emergency department (ED)-based HIV testing and linkage-to-care (LTC) program at Johns Hopkins Hospital in 2005 and HCV program in 2015 and is currently the co-PI of both programs. Dr. Hsieh’s scientific work has identified the gaps of the ED-based HIV and HCV screening and LTC program, resulting in improved understanding of national and local trends in ED-based HIV and HCV testing, as well as epidemiological studies, through critical analysis of a national representative database and local seroepidemiological studies. Through these works, Dr. Hsieh built the first HIV Care Continuum for ED HIV-infected population and quantified gaps in HIV diagnosis and care. Dr. Hsieh and his colleagues at JHU have initiated an ED HIV PrEP referral program since 2018 and piloted an ED same day PrEP program in 2022. 

Dr. Hsieh has particular expertise in evaluations of novel diagnostic assays in acute care setting as well as study design, participant enrollment, user’s feedback survey, quantitative and qualitative statistical data analysis in performance evaluation studies, especially in point-of-care assay industry and end-user needs assessment and performance and validation of novel diagnostic assays in the field of infectious disease screening programs and acute and indolent infectious diseases in the acute care setting.
