Julie P.W. Bynum, MD, MPH, is Associate Professor of Medicine at Dartmouth Medical School and at The Dartmouth Institute for Health Policy and Clinical Practice, where she is also the Co-Director of the Data Analytic Core. Dr. Bynum joined the faculty at Dartmouth in 2003 after completing both of her degrees and a research fellowship in Geriatrics at Johns Hopkins University. Her primary interest is in improving the delivery of health care to vulnerable elderly, especially those over the age of 80 and the cognitively impaired. Dr. Bynum’s research has focused on assessment of health system performance for the elderly using national U.S. Medicare administrative data. To support this work, Dr. Bynum has received funding from the American Geriatric Society Foundation for Health in Aging, the Robert Wood Johnson Physician Faculty Scholar, the a National Institute of Aging Beeson Career Development Award in Aging (K23) to study quality and efficiency of healthcare delivery to high-risk elderly. One of Dr. Bynum’s s contributions from that period was the development of “virtual” Physician-Hospital Networks using Medicare data to assess care delivery by specific provider groups that can be used to model the design and potential impact of policies related to Accountable Care Organizations. She currently is Principal Investigator on several NIH grants and on a Hartford Foundation grant to study to study High Cost High Need Older Adults.
