Why does the U.S. have worse health outcomes despite spending more on healthcare compared to other high-income countries?

The U.S. spends significantly more on healthcare than other high-income countries, yet it has the worst health outcomes on almost every metric. A report by The Commonwealth Fund highlights that despite high healthcare spending, many Americans skip or delay care due to affordability issues. The report's author, Munira Gunja, suggests that to improve health outcomes, the U.S. needs to expand access to healthcare, control costs, and invest in health equity and social services. The study compared the U.S. to countries like Australia, Canada, Germany, Japan, South Korea, and the UK. Unlike these countries, the U.S. does not guarantee health coverage, with 8.6% of Americans uninsured in 2021. The U.S. also had the fewest annual healthcare visits, averaging just four per year. Additionally, 30% of U.S. adults have multiple chronic conditions, such as diabetes, heart disease, and mental health issues. The U.S. ranks poorly in life expectancy, avoidable deaths, infant and maternal mortality, and obesity. However, the U.S. did not have the worst outcomes in suicide rates, ranking third behind Japan and South Korea.
