​Since January 2017, Republicans have sought to swiftly repeal the Affordable Care Act (ACA) and put forth multiple approaches to replace it, including the American Health Care Act, which the Congressional Budget Office has estimated will cost up to 24 million Americans their health insurance over the next decade. In this Health Forum, co-sponsored by the UCLA Fielding School of Public Health and the UCLA Center for Health Policy Research, experts will explore the latest developments in this high-stakes process. The panel will consist of Gerald Kominski, director of the UCLA Center for Health Policy Research; Alexander Li, deputy director of systems integration, Los Angeles County Health Agency; and Mark A. Peterson, professor of public policy, political science and law and chair of the Department of Public Policy, UCLA Luskin School of Public Affairs. The panel will be moderated by Thomas Rice, professor at the Department of Health Policy & Management, UCLA Fielding School of Public Health. This seminar, co-sponsored by the UCLA Center for Health Policy Research and the UCLA Fielding School of Public Health, is one of a series of special Public Health Grand Rounds seminars dedicated to the fate of the Affordable Care Act.
