According to the State Scorecard released by the Commission on a High Performance Health System, the quality of health care varies widely across the United States--with significant room for improvement in every state. Several of the top-performing states have formed interagency quality partnerships, many involving the private sector. Understanding how these partnerships work could offer insights for other states. This project will: 1) analyze the key components, policies, and practices that contribute to the formation and success of quality improvement structures; and 2) disseminate this information nationally to assist other states seeking to form quality improvement partnerships, as well as to provide a way for leading states to learn from each other as they refine and advance their efforts. Project staff will convene leading states for a "quality summit," maintain a listserv of interested state officials, and lead a session at the National Academy for State Health Policy's annual meeting.
