"Despite spending nearly twice as much on healthcare per capita, utilization rates for many services in the United States is lower than other wealthy OECD countries."
"In fact, the United States spends over $1,000 per person on administrative costs — approximately five times more than the average of other wealthy countries"
"Despite higher healthcare spending, America’s health outcomes are not any better than those in other developed countries. The United States actually performs worse in some common health metrics like life expectancy, infant mortality, unmanaged diabetes, and safety during childbirth."
