RAND Distinguished Chair in Health Care Delivery Measurement and Evaluation
Co-Chair Health Systems Work Group, Community Engagement Core/ CTSI

Dr. Kahn is professor of medicine in the Division of General Internal Medicine and Health Services Research. She is a primary care physician/ general internist caring for patients and teaching in the ambulatory setting and hospital. She is also a senior natural scientist at RAND and has served as the RAND distinguished chair in health care delivery measurement and evaluation. Dr. Kahn has over 30 years of experience leading multiple national and local projects involving health care program evaluation, health care quality measurement and improvement, patient-reported outcomes, measurement of structure-processes-and-outcomes, and the medical home. As a general internist with a special interest in generalist-specialist interactions, she participated in defining strategies for assessing dyspepsia with the Public Policy Committee of the American College of Physicians (1984-87), was involved in the development of RAND’s initial measurement strategies for assessing appropriateness of GI procedures (1983-1987), was the first to establish methodologies for systematically assessing the appropriateness of use of esophagogastroduodenoscopy in ambulatory settings (1988), and the first to systematically stratify appropriateness ratings according to patient’s burden of illness (1988). Dr. Kahn has pursued the effectiveness of other measurement strategies for GI symptoms, participated in studies related to colorectal cancer screening, and studied outcomes for patients who have been diagnosed with colorectal cancer. She continues with active interests in the interface between generalists and specialists and with an interest in understanding how structural aspects of care can facilitate individual- and population-based processes and outcomes.

Current projects related to GI/liver disease

  • Exploring options for improving colorectal cancer screening
  • Assessing the appropriateness of advanced imaging including for abdominal symptoms
