A surveillance project in the Michigan Department of Corrections reported an annual rate of 505.7 injuries per 1000 prisoners from April 1994 through March 1995.1 In the Hawaii correctional facilities, annual injury rates averaged 683 per 1000 prisoners from 1992 to 1996 (K.M.T., unpublished data, 1997). Intentional injuries (prisoner-prisoner, prisoner-guard, and self-inflicted) represented approximately one fifth of all injuries in these 2 prison systems.
