Faculty Positions

Research Interests

Dr. Williams’ current research projects examine the characteristics of primary care practices that correlate with patients’ use of emergency room services, compare the quality of surgical care among hospitals, and measure the cost-effectiveness of medical care. Dr. Williams is a member of a committee that writes guidelines for the management of patients with chronic stable angina for the American College of Physicians, the American Heart Association, and the American College of Cardiology. He recently has published articles that examine how changing competition among hospitals affects the quality of care for patients with acute myocardial infarction, and he is Associate Editor at Annals of Internal Medicine for a series titled “Improving Patient Care” that describes new systems for better patient care for cardiac and other patients.
