The health care system in the United State has struggled during the past few decades. This has been accompanied by many controversies and debates among U.S. policy makers and health insurance providers. Dissatisfaction with health care in the United States today can be divided into three main aspects of health care; coverage, cost, and quality. The first problem, coverage, is a major issue because about 15 percent of the population of the U.S. (45 million) is uninsured today. The first and second problems, coverage and cost, are somewhat related since the rising cost of obtaining health services is one of the main reasons why many individuals are currently uninsured. The third problem, health care quality, is as important as the other two problems because there is no point in providing health services to the public if the services provided are inefficient and of bad quality. For these and other reasons, there is a call for improvement in the U.S. health care system. In fact, studies show that the majority of individuals in the United States believe that the health care system in the U.S. requires major changes.
