Eugene Rich, M.D., is an expert on sources of practice variation in medical care with a focus on the influence of the policy, payment, and practice environments on health professionals’ decision making. As a practicing general internist, he has a longstanding interest in improving the delivery of primary care and the policies needed to accomplish this.  

In addition to his expertise in health services and health policy research, he has deep experience with clinical practice leadership, including roles as medical director, clinical program leader, and medicine department chair. Thus he has a strong practical understanding of the diverse range of provider organizations, their structure, financing, governance, and motivations, and how they vary across urban, suburban, and rural communities. 

Since joining Mathematica in 2010, Rich has led a number of projects, including an evaluation of American Recovery and Reinvestment Act’s investments in comparative effectiveness research and an effort to test an approach to collecting national, policy-research-relevant data on physicians and their practices. He also directs a project identifying barriers and facilitators to evidence-based care in medical and surgical specialty practices. For Mathematica’s work to develop a physician value-based payment modifier for the Centers for Medicare & Medicaid Services, he serves as senior adviser and plays a similar role on a project to develop learning systems for accountable care organizations.  

The author of more than 130 peer-reviewed publications, Rich is a frequent consultant to federal agencies, foundations, and managed care organizations. Past recognition includes the AcademyHealth Article of the Year Award in 2001 and a Robert Wood Johnson Health Policy Fellowship working with the House Committee on Ways and Means. Rich has also served as senior advisor to the Office of Science Policy at the National Institute of Health, scholar in residence at the Association for American Medical Colleges, and president of the Society of General Internal Medicine. He is a senior editor of the Journal of Comparative Effectiveness Research and holds an M.D. from Washington University in St. Louis.
