A cohort study investigated the specific outcomes of a health education coursed carried out by recently graduated physicians in an urban primary care setting in Israel. Questionnaires were used to study the effects of the programme on knowledge and awareness concerning antibiotic usage. The results showed a significant gain in knowledge about the causes of infectious disease, appropriate duration of antibiotic intake, side effects of antibiotics and the importance of compliance. In contrast with other studies, low income blue collar workers with less than high school education showed the most significant gains from the programme. Inexperienced physicians were able to implement a community health education programme with clearly defined goals.
