About Eugene

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 also 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 effort to collect policy-relevant national data on clinicians and their practices for the Agency for Healthcare Research and Quality (AHRQ). He is currently project director for AHRQ’s Coordinating Center for Comparative Health System Performance which supports efforts to enumerate and describe U.S. health systems. For the Alternative Payment Model Program Analysis Contract with the Center for Medicare & Medicaid Innovation he leads the review and analysis of Physician-Focused Payment Model proposals. He is senior advisor and provides quality assurance oversight on a number of other current projects for the Centers for Medicare & Medicaid Services and foundations, including Mathematica’s work to develop a physician value-based payment modifier, the evaluation of the Comprehensive Primary Care Plus model, and the Learning System for Accountable Care Organizations.

He is author of more than 140 peer-reviewed publications, and a member of the editorial board for the Journal of General Internal Medicine. Past recognition includes co-authorship on the 2001 AcademyHealth Article of the Year, Robert Wood Johnson Health Policy Fellowship working on physician payment reform with the House Committee on Ways and Means, past president of the Society of General Internal Medicine, and scholar in residence at the Association of American Medical Colleges. He holds an M.D. from Washington University in St. Louis.
