The Center for Outcomes Research (COR) serves as the scientific coordinating center for a number of national and international outcomes registries. COR’s responsibilities include maintaining patient and physician confidentiality, design of data collection instruments, data management and publication development.

COR is based in the Department of Surgery at the University of Massachusetts Medical School (UMMS) in Worcester, Massachusetts, part of the 5-campus UMass System. Established in 1994, COR is an outgrowth of the Worcester Deep Vein Thrombosis (DVT) Study, a five-year NIH-supported program, which demonstrated that physicians are more likely to improve their patient management practices if they are provided with valid data on their own practices and outcomes along with regional and national benchmarks. Fred Anderson, PhD, principal investigator of the Worcester DVT Study, and Research Professor of Surgery, turned the lessons of this study into the foundation for the Center for Outcomes Research.
