Impact of Educational Films on Antibiotic Prescription among Physicians: A Web-Based Survey in Japan

Abstract

Although antibiotics are most frequently prescribed for respiratory tract infections, effective interventions for their proper use by physicians have not been fully established. We assessed the impact of educational films on the rates of antibiotic prescriptions for respiratory tract infections using fictitious scenarios. In this nationwide web-based survey prospective study, a total of 1100 physicians were included. The physicians were required to view educational short films and determine the need for prescribing antibiotics in 10 fictitious scenarios involving adults diagnosed with different acute respiratory tract infectious diseases. The antibiotic prescription rates for each scenario were compared before and after viewing the educational short film. The rates of antibiotic prescription significantly decreased after viewing the educational film, especially in cases with a narrowly defined common cold (from 51% to 15%), mild pharyngolaryngitis (from 71% to 25%), and acute bronchitis without chronic respiratory underlying diseases (from 63% to 23%). Alternatively, a slight decrease in rates was observed in cases with moderate or severe rhinosinusitis (from 94% to 79%), moderate or severe acute pharyngitis (from 88% to 69%), and acute bronchitis with chronic lung disease (from 70% to 58%), for which antibiotics are recommended. Educational short films may encourage the proper use of antibiotics for respiratory tract infections; however, the possibility of undertreatment in patients requiring antibiotics must be considered.
