Both in terms of per capita spending and as a proportion of GDP, the United States spends significantly more on healthcare than any other country.

Despite this, the nation’s healthcare outcomes are noticeably inferior than those of its peer countries. The US is the only developed country without a system of universal healthcare, and a significant section of its population lacks health insurance, which significantly contributes to the excess mortality rate in the country.

Various entities, including insurance companies, healthcare providers, hospital systems, and independent providers, provide healthcare services. Private sector companies mostly own and run healthcare facilities. In the US, 21% of community hospitals are owned by the government, 21% are for-profit, and 58% are nonprofit. The US spent $9,403 (or $10,738 in 2021) on healthcare per person and 17.9% of its GDP on healthcare, according to the World Health Organization (WHO). A combination of private health insurance and public health coverage is used to provide healthcare coverage (e.g., Medicare, Medicaid). The government financed 64% of health spending in 2013 through initiatives like Medicare, Medicaid, the Children’s Health Insurance Program, Tricare, and the Veterans Health Administration. People under the age of 65 can obtain insurance through their employer or the employer of a family member, by buying health insurance independently, by receiving government help or other benefits depending on their income or another circumstance, or by being uninsured.

In its capacity as an employer, the government primarily provides health insurance for those working in the public sector. Managed care, in which payors employ various strategies meant to increase quality and reduce cost, is now pervasive. The US has increased its life expectancy from 75.2 years to 78.6 years at birth, placing it 42nd out of 224 countries and 22nd out of the 35 industrialised OECD nations—down from 20th in 1990. For the first time since 1993, life expectancy in the US declined in 2016 and 2017. The US had the highest or almost greatest prevalence of obesity, vehicle accidents, infant mortality, heart and lung disease, sexually transmitted diseases, adolescent pregnancies, injuries, and homicides in 2013 among the 17 high-income countries the National Institutes of Health analysed. The US healthcare system was found to be the most expensive and to perform the worst in terms of equity, efficiency, and access to health care in a 2017 study of the healthcare systems of 11 developed nations. In a 2018 research on healthcare access and quality, the US came in at number 29.

According to surveys conducted by the Gallup organisation starting in 2008, the percentage of adults without health insurance reached a high of 18.0% in 2013 before the Affordable Care Act (ACA) mandate, declined to 10.9% in the third quarter of 2016, and remained at 13.7% in the fourth quarter of 2018. One of the main issues mentioned by proponents of healthcare reform is the fact that there are over 27 million people in the US who lack health insurance coverage. Cofounders of Physicians for a National Health Program, a single payer advocacy group, conducted a study at Harvard Medical School and Cambridge Health Alliance in 2009 that indicated that roughly 45,000 deaths per year are related to patient health insurance. According to the report, the mortality risk for working Americans without insurance is almost 40% higher than that of working Americans with private insurance. The Patient Protection and Affordable Care Act (ACA), also referred to as “Obamacare,” was signed into law in 2010 and brought about significant changes to the way that health insurance was provided. The majority of the law was maintained as constitutional by the US Supreme Court in June 2012, and insurance exchange subsidies were upheld in all 50 states in June 2015.

In contrast to the nationalised health insurance programmes in Europe, the US market developed a private employment-based system. Following the Stabilization Act of 1942, employers started to offer insurance plans, including healthcare packages, as a fringe benefit in order to attract and keep workers because they were unable to offer higher salaries. This marked the beginning of the practise of employer-sponsored health insurance.


A statistical brief by the Healthcare Cost and Utilization Project (HCUP) states that 35.7 million people were admitted to hospitals in 2016, which is a considerable drop from the 38.6 million admissions in 2011. There were 104.2 stays on average for every 1,000 people in the population, costing an average of $11,700 ($13,210 in 2021) every stay, up from the $10,400 ($12,275 in 2021) per stay in 2012. In 2017, 7.6% of people spent the night somewhere, with each stay lasting 4.6 days on average.

Health Insurance and accessibility:

The US health system does not offer healthcare to every citizen of the nation, unlike most developed nations. Instead, a number of federal and state programmes, along with private insurance, cover the majority of the population. In 2017, 150 million people had access to health insurance through group plans that were affiliated with their employers. Medicare, which covers 50 million people, Medicaid, which covers 70 million, and the ACA-created health insurance exchanges, which serve about 17 million people, are additional significant sources. According to a 2017 survey, 73% of plans offered through ACA marketplaces had constrained provider networks that restricted access and choice.

The percentage of the population with insurance, having a regular source of medical care, visiting the dentist once a year, rates of avoidable hospitalisations, reported difficulty seeing a specialist, delaying care due to cost, and rates of health insurance coverage are some examples of accessibility and affordability indicators tracked by national health surveys. In 2004, an OECD assessment stated that “all OECD nations had achieved universal or near-universal (at least 98.4% insured) coverage of their populations by 1990, with the exception of Mexico, Turkey, and the US.” Poor addition, the 2004 IOM report noted that “inadequate health insurance results in some 18,000 avoidable deaths annually in the US.”

Since 2008, the Gallup organisation has kept track of the percentage of adult Americans without health insurance. Prior to the ACA mandate, the uninsured rate peaked in 2013 at 18.0%, dropped to 10.9% in the third quarter of 2016, and rose to 13.7% in the fourth quarter of 2018. “The net increase of nearly seven million persons without health insurance since that low is shown by the 2.8 percentage-point increase since that low.”

The number of persons without health insurance dropped from 49.9 million (16.3%) in 2010 to 28.5 million (8.8%) in 2017, according to the US Census Bureau. The trend of high rates of underinsurance and wage stagnation between 2004 and 2013 resulted in a fall in low-income Americans’ use of healthcare. Following the primary ACA provisions’ 2014 adoption, this tendency was reversed.

Interest in the issues of whether and how health insurance coverage influences health and mortality has increased as of 2017, in part due to the prospect that the ACA may be repealed or replaced. According to a number of studies, the expansion of the ACA and elements linked to improved health outcomes, like having a reliable source of treatment and the ability to pay for it, are related. According to a 2016 research, the Patient Protection and Affordable Care Act’s Medicaid expansion provisions contributed to an increase in ability to pay for care of almost 60%. In addition, an analysis of mortality changes following Medicaid expansion shows that Medicaid saves lives at a relatively more cost-effective rate, with a societal cost ranging from $327,000 to $867,000 (or $369,213 to $978,921 in 2021) per life saved as opposed to other public policies, which cost an average of $7.6 million (or $8.58 million in 2021) per life.

Medical debt was a factor in 46.2% of all personal bankruptcies, according to a 2009 study conducted in five states, while 62.1% of those who filed for bankruptcy in 2007 cited excessive medical expenses. Since then, both the expense of healthcare and the proportion of people with inadequate insurance have risen. According to a 2013 study, the cost of medical care causes roughly 25% of senior citizens to file for bankruptcy.

In reality, the uninsured are frequently treated, but the expense is shifted to taxes and other fees. The US may be ranked as having the highest healthcare expenses internationally despite large patient cost-sharing because of the medical care that is forgone due to extensive cost sharing, which may ultimately increase costs due to downstream medical difficulties.

Even those with insurance may not have enough coverage to cover necessary medical treatment. According to a 2003 survey, 16 million US individuals lacked adequate health insurance, disproportionately hurting those with lower means (among the study group, 73% of the underinsured had yearly incomes below 200% of the federal poverty level). Barriers to healthcare access include a lack of insurance or more cost sharing (user fees for those with insurance): utilisation of care decreases as patient cost-sharing obligations rise. Before the ACA was enacted in 2014, 39% of Americans with incomes below the median reported not going to the doctor when they had a health problem (compared to 7% of low-income Canadians and 1% of low-income Britons who said the same).

US death rates and its causes:

Since the 1990s, cardiovascular illnesses (ranked first), neoplasms (ranked second), and neurological disorders (ranked third) have continuously been the top three causes of mortality in the US for people of all sexes and ages. In 2015, there were a total of 155,041 fatalities from chronic lower respiratory disease, 633,841 deaths from cancer, and 633,841 deaths from heart disease. Cardiovascular illnesses were responsible for 267.18 deaths per 100,000 persons in 2015, neoplasms for 204.63, and neurological disorders for 100.66. Despite being placed sixth overall, diarrhoea, lower respiratory infections, and other common diseases had the highest rate of infectious disease mortality in the US, with 31.65 fatalities per 100,000 people.

Despite this, there is evidence that many health outcomes and early deaths are caused by causes other than communicable or non-communicable diseases. More over half of men who pass away before the age of 50 are killed in crimes (19%), car accidents (18%), and other accidents (16%), according to a 2013 National Research Council report. In contrast, 38% of women who pass away before the age of 50 pass away through accidents, homicide, or suicide, compared to 53% of males who pass away from disease. As of 2018, some 158,000 Americans each year die from diseases of despair (drug overdoses, alcoholic liver disease, and suicide), which began to rise in the early 1990s.

Employment of medical professionals in the US:

Since the “baby boomers” are approaching retirement age, there is a significant impending demographic shift in the US that will necessitate the expansion of the healthcare system. This is because the older population is expected to drive up medical costs by 5% or more in North America. Since the late 1990s, there has been an increase in total healthcare spending that is not only attributable to general price increases because the rate of spending growth is outpacing inflation. Additionally, the maximum cost of health treatments for those over 45 is 8.3 times greater than for those under 45.

Medical Equipment, Development, and Research:

Pharmaceutical and medical device production is handled by private enterprises, as is the case in the majority of other nations. Both governmental and commercial financing sources are used to assist medical device and pharmaceutical research and development. Approximately $95 billion was spent on research and development in 2003 (equal to $136 billion in 2021), of which $55 billion (equivalent to $78.8 billion in 2021) came from private sources and $40 billion (equivalent to $57.3 billion in 2021) came from public sources. When evaluated in terms of income or the number of new drugs and technologies introduced, the US has become the global leader in medical innovation thanks to these investments in medical research.

Pharmaceutical businesses in the US spent an estimated $59 billion on research and development in 2016, which would increase to $66 billion in 2021. Three-quarters of global biotechnology income and 82% of global biotechnology R&D expenditures in 2006 were accounted for by the US. Many overseas pharmaceutical trade associations claim that the US’s high cost of patented medicines has significantly increased spending on such research and development. However, the ACA will compel the pharmaceutical industry to offer drugs at lower prices. As a result, it’s probable that funding for US human health and medical research will be reduced.

Insurance for Health care for Immigrants:

In 1998, there were 26.2 million foreigners living in the US; 62.9% of them were not US citizens. Compared to the 14.2% of native-born Americans without health insurance coverage, 34.3% of foreign nationals living in the US did not have it as of 1997. Compared to non-citizens, who make up 43.6% of the population, 18.5% of immigrants who became citizens were uninsured. Immigrants are less likely to have health insurance across all age and income groups. Many legal immigrants with different immigration statuses might now qualify for low-cost health insurance because to recent developments in healthcare.

Government-funded health insurance is not available to undocumented immigrants in the US. Although the ACA permits non-citizens to receive insurance at a higher cost, this is not the case for immigrants. Although laws like the Patient Protection Act and the Affordable Care Act sought to increase access to health insurance in order to improve refugee health in the US, different states’ health insurance programmes were implemented in a variety of ways, resulting in regional differences in healthcare access. In the US, undocumented immigrants can access fee-for-service medical assistance and seek medical attention through community centres, or so-called Safety Net Providers, but they can only purchase health insurance from private health insurers.
