The American medical care system falls to provide effective prevention services even though some prevention services are among the most cost-effective medical procedures available. Many prevention services are routinely delivered in inefficient or ineffective ways, and new technologies may be widely and aggressively implemented despite serious doubts about their efficacy and cost-effectiveness. The barriers to effective prevention services result from conceptual limitations in our model of medical care systems, particularly the lack of a population-based perspective. A change in paradigm is needed before reforms in our health care system can improve health without bankrupting the nation.

Uninsured Americans often face barriers to or lack continuity of care. Care for this population is often fragmented, expensive and undercompensated. University Hospital in Denver, in partnership with Kaiser Permanente of Colorado, sought to address this problem by developing CU CARE, a managed care demonstration program for the medically uninsured within the University of Colorado Health Sciences Center. This paper describes the evolution and preliminary experience of the CU CARE program. Policy implications for the future of health care delivery to this population are also briefly discussed.
