The U.S. healthcare system is ranked the worst among 11 developed nations, according to a new study.

The Commonwealth Fund measured elements including care, access, administrative efficiency, equity and healthcare outcomes in Australia, Canada, France, Germany, the Netherlands, New Zealand, Norway, Sweden, Switzerland, the United Kingdom and the United States.

Its analysis found the U.S. spent the most money on healthcare and also ranks poorly in terms of access, equity and healthcare outcomes.

Nearly half of low-income Americans, 44 percent, were found to have trouble getting access to healthcare coverage, while just 26 percent of high-income Americans were found to have issues getting coverage.

The study comes as the GOP struggles to repeal and replace ObamaCare.
