Justin Timbie is a senior health policy researcher at the RAND Corporation. His research focuses on value-based payment, health care organizational models and their effects on providers and patients, and health policy issues involving the safety net. He has over ten years of experience conducting evaluations of complex programs including evaluations of patient-centered medical home programs, global budget payment models, and reinsurance programs. Timbie’s research on health care organization and delivery includes studies of the impact of vertical integration on socioeconomic disparities in care and its effects on rural health care markets. He has also studied clinical integration between community health centers and other health care organizations and the effects of health system-affiliation on racial and ethnic disparities in care and the quality of care for high-need Medicare beneficiaries. Timbie has provided technical assistance to states seeking to implement value-based payment, and he currently provides technical assistance on policy analysis to the HHS Office of the Assistant Secretary for Planning and Evaluation, which has included studies of the impact of the Affordable Care Act on safety net providers. Timbie has conducted research on quality of care in the Medicare Advantage (MA) program, which included comparisons of performance between MA and Traditional Medicare and studies on geographic variation in quality in MA. Timbie received his doctoral degree in health policy from Harvard University and completed a postdoctoral fellowship in the Veterans Affairs Health System.
