The United States has the least popular healthcare system out of 10 developed countries that were surveyed by Harris Interactive, with a third of Americans saying it needs a complete overhaul.
Thirty-three percent of Americans said the US system "has so much wrong with it that we need to completely rebuild it," while a further 50 percent said "fundamental changes are needed to make it work better," a survey conducted in May showed.
The Dutch healthcare system fared best, with only nine percent saying it needed a complete revamping, a separate poll showed.
Only 12 percent of Spaniards and Canadians want their healthcare system totally revamped, 15 percent feel the same way in France and Britain, 17 percent in New Zealand, and 18 percent in Australia.
One in five Italians saw their country's healthcare system in a poor light, putting it in second-to-last place ahead of the United States, which was still far and away the least popular.
France led the way among people who think their healthcare system is the envy of the world, with 70 percent of the French thinking along those lines.
In Britain, 59 percent think the National Health Service makes the rest of the world go green with envy.
Nearly seven in 10 Britons think the National Health Service is "crucial to British society and we must do everything to maintain it."
Ten surveys were conducted, each polling around 1,000 people, in Australia, Britain, Canada, France, Germany, Italy, the Netherlands, New Zealand, Spain and the United States.
