Testing the physician's knowledge of antibiotic use: Self-assessment and learning via videotape.

Because recent reports suggest that physicians in the United States do not use antimicrobial agents properly, we analyzed scores for the first 4513 physicians viewing the National Antibiotic Therapy Test, a nationally televised self-assessment test on the diagnosis and treatment of infectious diseases. The 75-minute videotape test, produced by the Network for Continuing Medical Education, contained three section: a 10-question pre-test, a 25-question teaching test, and a 15-question post-test. Scores were tabulated according to the specialty, years in practice, and volume of patients seen. The mean correct score was 68 per cent for all 50 questions, 55 per cent for the 10 pre-test questions, and 71 per cent for the 15 post-test questions. Physicians in practice for one to five years, residents and internists scored better than other subgroups. Answers to questions indicated deficiencies of knowledge and the need for further postgraduate education in the use of antibiotics.
