Profile of trauma due to violence in a statewide prison population.

Acts of violence within a statewide prison population were reviewed to determine the incidence, types of injuries, surgical procedures required, persons involved in the trauma, and weapons used to inflict the injuries. The objective was to identify trends to aid in developing methods of prevention. Over a 3-year period, 1600 prisoners from the state of Tennessee were hospitalized at our institution. The majority were from the maximum security unit. There were 133 episodes of trauma. Our study focused on the first admission of 94 inmates. Fourteen (15%) of the injuries were self-inflicted, including seven self-inflicted penetrating wounds. Nineteen different weapons were used to inflict trauma. Prison cafeteria utensils and workshop utility and office devices may need to be redesigned because these items are frequently used in acts of violence. Victims subjected to repeated episodes of violence should be relocated. Lastly, self-mutilators may need to be transferred to an institution for the mentally impaired for their own protection.
