About Arkadipta

Arkadipta Ghosh is an expert in program evaluation with extensive experience evaluating Medicare payment and delivery system reforms, including primary care redesign, financial incentives for care management and use of health information technology. He studies population health issues, health care use and costs, and quality of care, with a special interest in the Medicare and Medicaid populations.

Ghosh plays a lead role in studies related to primary care expansion and payment reform in Medicare. For the Evaluation of the Comprehensive Primary Care Initiative (CPC), he leads the development, testing, and dissemination of quarterly feedback reports generated from Medicare data to participating primary care practices and regions; he is also evaluating the impact of CPC on Medicare costs, service utilization, and quality of care using a quasi-experimental research design. On the evaluation of the Independence at Home Demonstration, which is testing the benefits of a home-based primary care model for high-need Medicare beneficiaries, Ghosh leads the claims-based analysis for estimating the program’s impact on Medicare costs, service utilization, and use of prescription drugs. In addition to U.S. health policy, he is interested in international development and population health issues.

Ghosh publishes in peer-reviewed journals, including Health Affairs, Health Services Research, Economic Development and Cultural Change, and Forum for Health Economics and Policy, for which he also serves as a referee. He is also a referee for the American Journal of Managed Care and the American Journal of Pharmacy Benefits. Ghosh is a member of the American Society for Health Economists and AcademyHealth. A finalist for the 2010 Annual Research Award from the National Institute for Health Care Management, he holds a Ph.D. in policy analysis from the Pardee RAND Graduate School, and was an assistant policy analyst for the RAND Corporation prior to joining Mathematica in 2008.
