Of the approximately 257.8 million individuals currently living in the United States of America, every one of them has a need for effective, affordable and accessible health care coverage and services. Within the past thirty to forty years, the scope and cost of health care coverage and services has drastically changed, altering the manner in which health care was previously managed.

There are several factors that have affected the cost of health care coverage over the course of the past two to three decades.

One of these factors is the introduction and rapidly increasing enrollment in managed health care insurance plans. Managed care health insurance plans can, in most cases, help to alleviate the rising costs of effective medical coverage. Another important factor that has affected health care costs is the invention and implementation of new medical technologies. As prominent researchers and economic analysts have discovered, there is a distinct and direct correlat! ion between advancing medical technologies and rising health care costs. Medical innovation has been proven time and again to be an important determinant of health care cost growth. It would appear that managed care health insurance plans, which attempt to lower health care costs, and highly expensive new medical innovations and procedures are at cross purposes, pulling against one another in very different directions. Market-level comparisons have found the cost growth of health care in markets with greater managed care penetration to be generally slower than that of non-managed care health insurance markets. However, managed care is unlikely to prevent the share of gross domestic product spent on health care from rising unless the cost-increasing nature of new medical technologies changes.
