Jack Hadley, Ph.D., is a Professor and Senior Health Services Researcher in the Department of Health Administration and Policy at George Mason University. Most recently, he was a Principal Research Associate with The Urban Institute’s Health Policy Center and a Senior Fellow at the Center for Studying Health System Change, both located in Washington DC. His prior positions include Professor and Director of the Institute for Health Care Research and Policy at Georgetown University, Board Member and President of AcademyHealth, the professional association for health services and health policy researchers, and Editor of Inquiry, a professional journal devoted to health services research and policy. Dr. Hadley received a B.A. in economics from Brandeis University in 1968 and a Ph.D. in economics from Yale University in 1975.
Dr. Hadley's past research has emphasized empirical analysis of various issues in health care organization and financing. He has conducted studies of the financing and costs of care used by the uninsured, the determinants of health insurance coverage, the consequences of being uninsured, access to care, physician and hospital payment, medical education financing, hospital efficiency, assessment of the outcomes of medical treatment, and the effects of managed care on health care delivery systems. Much of his work has analyzed large data bases such as national household and physician surveys, Medicare claims and national hospital data in order to understand patient, provider, and system responses to policy changes.
Currently, Dr. Hadley’s research focuses primarily on issues related to costs and efficiency in the Medicare program. One study is investigating the sources of variations in Medicare and total medical care spending per Medicare beneficiary, and whether there are subsequent effects on changes in beneficiaries’ health. Two other projects link data from national surveys of physicians and insurance claims from their Medicare patients to study the relationships between Medicare fees and the supplies of physicians’ services and, more broadly, the effects of physicians’ financial incentives on the cost, quality, and efficiency of care provided to their Medicare patients. Another study in conjunction with the National Cancer Institute will investigate methodological issues in using observational data to evaluate the outcomes of alternative cancer treatments for elderly patients.
Building on his current research, he plans to focus his teaching activities around policy and research issues in the Medicare and Medicaid programs. Possible future studies include the effects of practice and market characteristics on the cost of care received by high-cost Medicare patients, who account for a substantial share of Medicare’s total spending, and the effects of physicians’ financial incentives on treatments and outcomes of Medicare patients with back/spine disorders.
