Only about 25% of U.S. consumers say they feel extremely secure about health care, and 63% say they would pay higher taxes to support a universal health care system.

Researchers at Catholic Healthcare West, San Francisco, uncovered those results while analyzing results from a recent survey of 1,771 U.S. adults ages 18 and older.

The hospital system commissioned the survey to support a new Health Security Index that will be based on consumer answers to a list of 17 questions.

The first overall average HSI total stands at 66 on a 100-point scale, with an average HSI of 60 for survey participants earning less than $35,000 per year and an average HSI of 74 for participants earning more than $75,000 per year.

About 46% of the survey participants said the U.S. health care system is getting worse, and 26% said it is worse than the health care system in other developed countries, Catholic Healthcare researchers report.

Roughly 20% of all participants and 44% of uninsured participants said they had skipped a recommended health test in the past year because they could not afford it, the researchers write.
