Reforming the health care delivery system.

The health care delivery system is evolving rapidly. There have been changes in the way health care is financed, the types of treatments available, the sites of care, and the physician patient relationship. These changes have resulted primarily from reactions to health care cost inflation. Health care reform is likely to accelerate some of these changes. The threat/promise of health care reform has already accelerated the consolidation of the health care services market. Health care reform is likely to reduce the number of insurers, increase the number of Americans in managed health care plans, increase the number of physicians in group practice, change provider income, and in general make the health care delivery system more concentrated and vertically integrated.
