Interdisciplinary Health Services Research

CHOP's work is led by twelve R01-funded principal investigators with over $30 million in extramural funding. Our work has been cited by over 50 government and policy organizations worldwide, including the World Health Organization, the Department of Justice, MedPAC, AHRQ and Bipartisan Policy Center. 

Our research is supported by significant extramural funding from AHRQ and NIH across a broad range of domains and methodologies. These serve as foundations for our work supported through other mechanisms (e.g. training grants, career development grants, and foundation grants.)

Zip code and hospital quality may both affect the risk of dying after surgery
Researchers analyzed whether the neighborhood a patient lived in or the quality of the hospital they went to for an operation affected their recovery from surgery

Well-Being at Michigan Medicine
Episode 1: The Enterprise Triad
The inaugural episode of Well-Being at Michigan Medicine has Dr. Elizabeth Harry welcoming the organization’s triad leadership – Dr. Paul Lee of the U-M Medical Group, Julie Ishak, M.S.N., the chief nurse executive, and Dr. Charlie Reuland, the chief operations integration officer overseeing operations at the clinical enterprise. Some of the topics that the quartet discuss include fostering a culture of people feeling cared at work and how it can make a difference in patients’ lives, recognizing stress and structural issues and how to stave off burnout, and reducing cognitive load. Learn more about the host of Well-Being at Michigan Medicine, Dr. Elizabeth Harry. Episode guests: • Julie Ishak, M.S.N., R.N. • Paul Lee, M.D., J.D. • Charlie Reuland, Sc.D., M.H.S.
