March 25, 2009—The Fund's series of case studies on high-performing health care organizations seeks to highlight the programs and practices that make for effective and efficient health care delivery. The latest organizations to be profiled are Baylor Health Care System, a nonprofit integrated delivery system in the Dallas–Fort Worth area, and Hill Physicians Medical Group, the nation's largest independent practice association. As described by Tom Emswiler and Len M. Nichols of the New American Foundation, both organizations have achieved improvements in patient outcomes and care processes by earning physicians' trust and securing their commitment to quality improvement, creating incentives and fostering competition, and enabling continuous learning.
