MD-PhD student Alexander C. Tsai, along with Center faculty Mark E. Votruba, PhD and Randall D. Cebul, MD, and former Case faculty member John Bridges, PhD (now of the University of Heidelberg), published a manuscript in the journal Health Services Research in the February 2006 issue. The study, “Overcoming Bias in Estimating the Volume-Outcome Relationship”, examines the relationships between volume and outcomes of care for patients with congestive heart failure using a novel instrumental variables strategy based on the geographic distribution of patients and hospitals in Northeast Ohio.
