A Baylor College of Medicine study found physicians may be overconfident in their diagnostic decisions, which could affect patient care, and researchers said health care facilities need better ways of telling doctors their diagnoses are not correct. Study data reported in JAMA Internal Medicine found physicians expressed similar levels of confidence in diagnoses for difficult and easy cases when they were correct only about 6% of the time in tougher calls, compared with 55% of the time in easier situations.
