    Abstract:
    A significant minority of instances of endocarditis appear to be the result of invasive procedures performed in susceptible patients with underlying cardiac conditions. Absence, or inappropriate administration, of antimicrobial prophylaxis could expose the patient to the development of a potentially lethal infection. This study was formulated, therefore, to assess the knowledge of guidelines for the prevention of infective endocarditis among hospital-based physicians and surgeons. A multiple choice test was developed, including: (1) cardiac conditions at increased risk for development of infection; (2) procedures more likely to be associated with bacteraemia and endocarditis; and (3) type and route of antimicrobials prescribed when endocarditis prophylaxis is indicated. The quality of the test was determined in several ways. Success was defined as a pass rate of 11 of 18 questions (61%). The test was taken by 153 of 251 (60%) physicians employed by the hospital; 95 (62%) passed the test. No significant difference in success rates was found according to sex, professional status or medical school. Internists performed substantially better (with a pass rate of 41 of 53, 77%) than both paediatricians (13 of 26, 50%, P<0.05) and surgeons (41 of 74, 55%, P<0.01). The range of success varied from 100% to 36% according to specialty (P<0.001). The mean score was 69+/-21 in the study group and 94+/-10 in a control group of 20 infectious disease physicians (P<0.001). In conclusion, this study demonstrates the need for improved education of hospital-based clinicians regarding endocarditis prophylaxis recommendations.
