The Dartmouth Atlas Working Group

Leadership

David C. Goodman, M.D., M.S., Dartmouth Atlas Co-Principal Investigator
David C. Goodman is Professor of Pediatrics and of Health Policy; Director of the Center for Health Policy Research; and Co-Principal Investigator, Dartmouth Atlas of Health Care. Dr. Goodman's primary research interest is in variation of health workforce supply and its relation to health outcomes. Dr. Goodman has also led numerous studies on variation in the effectiveness and efficiency of health care, including neonatology, pediatrics hospital and asthma care, and medical care in Medicare beneficiaries. Dr. Goodman is a member of the editorial board of the journal Health Services Research and of the Institute of Medicine Committee on the Future of Nursing. Dr. Goodman received his medical degree from the State University of New York Upstate Medical Center and his Masters degree in medical care epidemiology from Dartmouth College. He served his residency in pediatrics at The Johns Hopkins Hospital in Baltimore, and then practiced as a rural National Health Services Corps physician. After joining the Dartmouth faculty in 1988, he undertook allergy and clinical immunology training. He recently stepped down as Chief of the Section of Allergy and Clinical Immunology, a position he held for a number of years.

Elliott S. Fisher, M.D., M.P.H., Dartmouth Atlas Co-Principal Investigator
Dr. Fisher is Professor of Medicine and Community and Family Medicine at The Geisel School of Medicine at Dartmouth, Director of Population Health and Policy, and Director of the Center for Population Health at The Dartmouth Institute for Health Care Policy and Clinical Practice. He received his undergraduate and medical degrees from Harvard University and completed his residency in internal medicine at the University of Washington, where he was also a Robert Wood Johnson Clinical Scholar and received a Masters in Public Health. His research focuses on exploring the causes of the twofold differences in spending observed across U.S. regions and health care systems - and the consequences of these variations for health and health care. He currently serves as co-chair of the National Quality Forum committee developing a new national measurement framework for evaluating and improving health system performance. He has served on the National Advisory Council of the Agency for Healthcare Research and Quality (AHRQ) and is a member of the Institute of Medicine.

John E. Wennberg, M.D., M.P.H., Founder of the Dartmouth Atlas
John E. Wennberg, M.D., M.P.H., is the Peggy Y. Thomson Professor (Chair) in the Evaluative Clinical Sciences and Founder and Director Emeritus of The Dartmouth Institute for Health Policy and Clinical Practice (formerly the Center for the Evaluative Clinical Sciences). He has been a Professor in the Department of Community and Family Medicine since 1980 and in the Department of Medicine since 1989. Dr. Wennberg is a member of the Institute of Medicine of the National Academy of Sciences and the Johns Hopkins University Society of Scholars. He has received numerous awards, including the Institute of Medicine's 2008 Gustav O. Lienhard Award, the Association for Health Services Research's Distinguished Investigator Award, the Richard and Hinda Rosenthal Foundation Award in Clinical Medicine, and the Baxter Foundation's Health Services Research Prize.

With colleague Alan Gittelsohn, he developed a strategy for studying population-based rates of health resource allocation and utilization (small area analysis), which revealed large variations in the rates among local and regional health care markets, much of which appeared to relate to the distribution of supply of resources and to differences in local medical opinion. Together with colleagues in Maine and Boston, Dr. Wennberg undertook a series of studies designed to reduce scientific uncertainty, primarily in the area of prostate disease (where surgical procedures had been shown to vary by a factor of three or more among neighboring regions). Efforts to clarify the outcomes and the theoretical basis for undertaking prostate surgery led, in turn, to awareness of the importance of patient preference in the rational choice of treatment and to studies involving the patient as an active participant in the choice of treatment. Dr. Wennberg is the founding editor of The Dartmouth Atlas of Health Care.

Jonathan S. Skinner, Ph.D., Senior Scholar
Dr. Skinner is the John Sloan Dickey Third Century Chair of Economics at Dartmouth College. His research interests are the determinants of health care spending and outcomes among different income groups in the Medicare population. He is currently studying how high- and low-income groups are treated differently for heart attacks, and to what extent the better survival outcomes for high-income groups are the consequence of differing treatment patterns. He has also studied the redistributional effects of the Medicare system and the time-series pattern of catastrophic out-of-pocket expenditures. His related research in economics focuses on why households save, and why so many households save virtually nothing for their retirement. Dr. Skinner is a member of the Institute of Medicine.

Kristen K. Bronner, M.A., Managing Editor
Ms. Bronner is a Research Associate with The Dartmouth Institute for Health Policy and Clinical Practice and the Managing Editor of the Dartmouth Atlas. She has been a member of the Dartmouth Atlas project team since 1995. She edits, designs graphics, and oversees production of Dartmouth Atlas publications, and works with the investigators, programmers, and analysts to improve and expand the Atlas database. She is also the Atlas webmaster and primary content developer for the Dartmouth Atlas web site.
