Physician and dentist compliance with American Heart Association guidelines for prevention of bacterial endocarditis.

To determine the rate of physician and dentist compliance with the American Heart Association's (AHA) recommendations for prophylaxis against bacterial endocarditis--considered the standard of care--questionnaires were mailed to 1,131 dental and medical practitioners. They were asked to identify various cardiac conditions requiring prophylaxis and dental procedures that would cause a bacteremia, and to write prescriptions for prophylactic antibiotics for five different scenarios. Both groups had low compliance with AHA recommendations (32.9% collectively) when prescribing appropriate antibiotic regimens for bacterial endocarditis prophylaxis.
