Chiang-Hua Chang

I am a health service researcher and a faculty member in the Department of Cardiac Surgery at the University of Michigan. I joined the University of Michigan in 2019 after spending many years at Dartmouth. I earned my Ph.D. in Evaluative Clinical Sciences from The Dartmouth Institute, following my work as a master’s-trained statistician on The Dartmouth Atlas team. At Dartmouth, I developed expertise in observational studies regarding healthcare in Medicare. My primary interests include studying regional variation, the physician workforce, primary care delivery in underserved areas, dementia care, alternative payment models, and quality care for vulnerable older adults. Specifically, I was a key scientist on the Primary Care Service Area (PCSA) Project, funded by the Health Resources & Services Administration (HRSA), which aimed to define geographic areas for local primary care markets. Primary Care Service Areas are utilized to assess access to primary care resources, particularly in underserved areas, by federal and state governments. Additionally, I have employed Medicare claims data to analyze cancer care delivery patterns, end-of-life quality care, the risk effects of prescription use, low-value care, and polypharmacy among dementia patients. In addition to my research, I serve as a faculty member in the Data & Methods Hub of the Institute for Healthcare Policy & Innovation, where I provide consultations for Medicare and Medicaid.
