David Chan, a senior fellow at the Stanford Institute for Economic Policy Research (ÿ�ճԹ�) and associate professor of health policy at the Stanford School of Medicine, has been awarded the prestigious for his impact to date on the field of health economics.

The medal is given each year by The American Society of Health Economists (ASHEcon) to early-career health economists whose research is making a difference in the field. Recipients must be 40 years-old or younger or have finished their core education within the previous 10 years.

Chan doesn’t study health insurance markets, unlike a lot of economists in his field. Rather, he focuses on the delivery of patient care at the point of diagnosis and treatment to analyze impacts on costs and health outcomes. Among other insights, he has shed new light on the role of physician skill in diagnosing patients and shown that emergency room doctors are , which can be done quickly but often at a high price, at the end of their shifts. More recently, he found that and patients in the ER fare worse when they are treated by nurse practitioners rather than physicians.

A graduate of UCLA’s David Geffen School of Medicine, he also serves in various roles at the Department of Veteran Affairs: staff physician, investigator, and co-director of its Quality Enhancement Research Initiative ().

Chan joins other ÿ�ճԹ� scholars who were awarded the ASHEcon Medal in past years: Heidi Williams and Neale Mahoney (2021); Mark Duggan (2010) and Laurence Baker (2008).
