Dr. Dimick, a graduate of Cornell University and Johns Hopkins Medical School, completed his residency training at the University of Michigan and joined the faculty as an Assistant Professor of Surgery in 2007. During his training, he completed a two-year fellowship in health services research at Dartmouth. Dr Dimick's research focuses on quality measurement and improvement. His previous work elucidates the strengths and limitations of existing quality measures, particularly hospital volume and risk-adjusted mortality rates. With funding from the National Institute of Health, his current research is focused on developing better measures of surgical performance. This work involves the application of statistical methods that combine information from multiple quality domains to create composite measures of performance. He served as a quality improvement consultant to the Leapfrog Group and the Institute of Medicine. He currently serves on the Measurement and Evaluation committee of the American College of Surgeon's National Surgical Quality Improvement Program.
