About 41% of U.S. adults say insurers are most to blame for rising health care costs.

Researchers at Harris Interactive Inc., Rochester, N.Y., have published that figure in a summary of results from a recent Web survey of 2,119 U.S. adults.

About 16% of the participants said the government is to blame for rising health care costs, and 16% said pharmaceutical companies are most to blame.

Only 6% said hospitals are most to blame, and only 4% said physicians are most to blame, Harris researchers report.

The researchers also found that 67% of the participants said providing basic health insurance for the uninsured is more important than providing better benefits for the insured, while 18% said improving benefits for the insured is more important.
