Health care in the United States is provided by many distinct organizations. Health care facilities are largely owned and operated by private sector businesses. 62% of the hospitals are non-profit, 20% are government owned, 18% are for-profit. 60--65% of healthcare provision and spending comes from programs such as Medicare, Medicaid, TRICARE, the Children's Health Insurance Program, and the Veterans Health Administration. Most of the population under 67 is insured by their or a family member's employer, some buy health insurance on their own, and the remainder are uninsured. Health insurance for public sector employees is primarily provided by the government. The United States life expectancy of 78.4 years at birth, up from 75.2 years in 1990, ranks it 50th among 221 nations, and 27th out of the 34 industrialized OECD countries, down from 20th in 1990. Of 17 high-income countries studied by the National Institutes of Health in 2013, the United States had the highest or near-highest prevalence of infant mortality, heart and lung disease, sexually transmitted infections, adolescent pregnancies, injuries, homicides, and disability. Together, such issues place the U.S. at the bottom of the list for life expectancy. On average, a U.S. male can be expected to live almost four fewer years than those in the top-ranked country. According to the World Health Organization (WHO), the United States spent more on health care per capita ($8,608), and more on health care as percentage of its GDP (17.9%), than any other nation in 2011. The Commonwealth Fund ranked the United States last in the quality of health care among similar countries, and notes U.S. care costs the most. In a 2013 Bloomberg ranking of nations with the most efficient health care systems, the United States ranks 46th among the 48 countries included in the study. The U.S. Census Bureau reported that 49.9 million residents, 16.3% of the population, were uninsured in 2010 (up from 49.0 million residents, 16.1% of the population, in 2009). A 2004 Institute of Medicine (IOM) report said: "The United States is among the few industrialized nations in the world that does not guarantee access to health care for its population." A 2004 OECD report said: "With the exception of Mexico, Turkey, and the United States, all OECD countries had achieved universal or near-universal (at least 98.4% insured) coverage of their populations by 1990." Recent evidence demonstrates that lack of health insurance causes some 45,000 to 48,000 unnecessary deaths every year in the United States. In 2007, 62.1% of filers for bankruptcies claimed high medical expenses. A 2013 study found that about 25% of all senior citizens declare bankruptcy due to medical expenses, and 43% are forced to mortgage or sell their primary residence. On March 23, 2010, the Patient Protection and Affordable Care Act (PPACA) became law, providing for major changes in health insurance. The Patient Protection and Affordable Care Act (Public Law 111-148) is a health care reform bill that was signed into law in the United States by President Barack Obama on March 23, 2010. Along with the Health Care and Education Reconciliation Act of 2010 (passed March 25), the Act is a product of the health care reform agenda of the Democratic 111th Congress and the Obama administration. The law includes a large number of health-related provisions to take effect over the next four years, including expanding Medicaid eligibility for people making up to 133% of FPL,[174] subsidizing insurance premiums for peoples making up to 400% of FPL ($88,000 for family of 4) so their maximum "out-of-pocket" pay will be from 2% to 9.8% of income for annual premium,[175][176] providing incentives for businesses to provide health care benefits, prohibiting denial of coverage and denial of claims based on pre-existing conditions, establishing health insurance exchanges, prohibiting insurers from establishing annual spending caps and support for medical research. The costs of these provisions are offset by a variety of taxes, fees, and cost-saving measures, such as new Medicare taxes for high-income brackets, taxes on indoor tanning, cuts to the Medicare Advantage program in favor of traditional Medicare, and fees on medical devices and pharmaceutical companies;[177] there is also a tax penalty for citizens who do not obtain health insurance (unless they are exempt due to low income or other reasons).[178] The Congressional Budget Office estimates that the net effect (including the reconciliation act) will be a reduction in the federal deficit by $143 billion over the first decade. http://en.wikipedia.org/wiki/Health_care_in_the_united_states
