ROCHESTER, N.Y. - Americans say they have lost considerable confidence in major U.S. institutions, including medicine, a poll indicated.

The Harris Interactive poll found that Americans have lost a "great deal of confidence" in medicine, the White House and small business leaders.

Confidence in the medical field dropped the furthest, from 37 percent last year to 28 percent this year. Confidence in the White House dipped from 22 percent last year to 15 percent this year, and confidence in small business leaders slid 54 percent to 4 percent, the poll found.

The only institution rated in the Harris Interactive Confidence Index to improve was the U.S. military. Confidence in military leaders increased from 46 percent to 51 percent.

The poll of 1,010 adults was conducted Feb. 5-11. No margin of error was reported.
