Two out of three Americans believe that health-care costs are increasing faster than improvements in the quality of care, according to a recent survey.

Seventy-five percent of the respondents also said that hospitals should be most accountable for holding down costs, more so than doctors or the government.Sixty percent felt confident about the quality of care delivered by physicians, while 83 percent expected doctors to take the greatest responsibility for quality of care on a day-to-day basis.

The nationwide survey, conducted by R.H. Bruskin Associates, was sponsored by BOC Health Care, Montvale, N.J., a conglomerate in the areas of critical care and home care. The survey involved 1,029 respondents, 18 years or older.
