A new video series aims to increase understanding of the changes happening in the U.S. health care system. In one video, Pamela Riley, M.D., M.P.H., senior program officer for The Commonwealth Fund's Program on Vulnerable Populations, explains how the Affordable Care Act will help to enhance health care access, quality, and outcomes for low-income, minority, and uninsured Americans. In another video, Melinda Abrams, vice president for the Fund's Program on Patient-Centered Coordinated Care, discusses how the medical home model is enhancing access to primary care, improving the quality of services, and lowering costs.
