Doctors Don't Practice What They Preach

A new report shows the nation's doctors don't practice what they preach.

The Annals of Internal Medicine says nearly half of all doctors admit they've failed to report colleagues who make serious medical mistakes -- even though the vast majority agree such mistake should be reported.

More than 30 percent of doctors refuse to treat patients who can't pay. And more than one-third say they would order an unneeded MRI scan for an insistent patient.
