MALPRACTICE WORRIES HELP DRIVE HEALTH COSTS
A substantial number of heart doctors -- about one in four -- say they order medical tests that might not be needed out of fear of getting sued, according to a new study... ****The idea that doctors prescribe more tests in order to make more money is a canard: the tests are usually done by OTHER doctors and there's no financial gain for the referral and such as radiologists are incapable of self-referral.****
