Reinventing the American hospital.

The American hospital is being reinvented to conform with the forces that are replacing the acute, inpatient-oriented illness model of health care with a disease-prevention, health-promotion, primary-care one. Although hospitals will no longer conduct the "core business" of American health care, they can play a key role by empowering others and facilitating the integration of health services across the continuum of care. New management and governance structures will be required, as will population-based health status needs assessments, new relations with physicians, re-engineering of the clinical processes, organization-wide commitment to improving quality, information systems that link patients and providers, and creation of an overall community care management system. Despite major barriers, there are examples of progress.
