A summary of the results of a conference on occupational homicide prevention, held in Washington, DC on July 23 to 24, 1990 was presented. Homicide was the third leading cause of occupational injury death from 1980 through 1985 in the United States. It accounted for nearly 13% of the total death from trauma in the workplace. It amounted for 12% of the deaths among men and 42% among women in the workplace. Topics discussed included the limitations of currently available data, the importance of specific research issues, and areas where further study is needed. Known prevention strategies were evaluated. Of the workplace homicide victims, 33% were employed in retail trade, 19% in service industries and 11% in public administration. Public administration had the highest rate of workplace homicide with 2.1 deaths per 100,000 workers. This division included law enforcement officers. Recommendations were made to improve the information gathered on death certificates, to conduct a 1 year census of occupational homicides through local and state health departments, to educate the workforce and to disseminate workplace homicide prevention information.
