Project Burn Prevention, an educational program about burn safety, was implemented in the Greater Boston area from October 1977 through May 1978. The program consisted of three components: a media campaign, a school-initiated intervention, and a community-initiated intervention. Estimates of burn incidence and severity of injury because of scald, flame, electrical or contact burns, or smoke inhalation were made on all patients coming to target- or comparison-area hospitals for a four-year period before the program, the eight months during the program, and the 12 months after the program. Analysis of burn incidence during and after the interventions showed that the school-initiated intervention did not reduce the incidence or severity of burn injuries. The community-initiated intervention may have brought about a moderate, temporary reduction in the rate of burn injuries, although the increase in burn incidence observed for the media campaign of educational messages broadcast to the Greater Boston area suggests that the more plausible explanation for this effect is random variation in burn incidence.
