UCLA Fielding School of Public Health's Dr. Yusuke Tsugawa, associate professor in the Department of Health Policy and Management, co-authored research that found clinical outcomes improve when patients and surgeon's ethnicity match.

The study found improved metrics in a subset of patients; when Hispanic surgeons operated on Hispanic patients, for example, it led to reduced length of stay, by half a day, and fewer readmissions to the hospital. 

The study, led by Dr. Evan Michael Shannon, an assistant professor of medicine and clinician-investigator in the division of general internal medicine and health services research at the David Geffen School of Medicine at UCLA, was published by the peer-reviewed journal BMJ Open. Along with his service at the Fielding School of Public Health, Tsugawa, a physician, is also an associate professor of medicine at the Geffen School and is affiliated with the Fielding School's UCLA Center for Health Policy Research.
