The preliminary results of the California Nurses Using Rural Sentinel Events (NURSE) project were presented. The Project has been conducting active surveillance and health education since 1991. The main objective of the project was to prevent occupational agricultural injuries. NURSE obtained current incident reports of agricultural occupational injuries from several sources. Health education outreach was designed and implemented using the results of the surveillance. The focus of the Project was in Fresno and Monterey counties where agriculture relied to a major extent on migrant workers. Initial contacts, interviews, and on site inspections of equipment and premises were part of the protocol for field investigations. Field investigations were intended to determine factors which contributed or caused the accident and to construct and recommend preventive strategies. The most frequent nature of injury was an open wound of the finger. Back strains were common, as were sprains, fractures, open wounds, and contusions. Foreign body in the eye was a common injury in Fresno county. The most frequent cause of injury was overexertion. Machinery was the second most frequent cause in Fresno and third in Monterey. Cutting/piercing objects and tools were third in Fresno and second in Monterey. Others included falls, being struck by a falling object, and being caught between objects. Many of the more than 5,000 specific incidents have been investigated in detail by interviews, record reviews, and on site inspections. Thirty five became the basis for NURSE reports specifically developed and disseminated to promote safety and prevent injury.
