Accidental and Homicidal Death in a Psychiatric Emergency Room Population

To identify potentially preventable mortality other than suicide among psychiatric emergency room patients, the authors compared the rates of accidental and homicidal death among 5,284 consecutive psychiatric emergency room patients with those expected for an age-, sex-, and racematched sample of the general population. The rate of accidental death was two and one-half times and the rate of homicidal death nearly twice the expected ratefor the matchedgeneral population. Diagnostic and demographic analyses indicated that increased risk of death from either cause was highest among alcobolics, schizophrenic patients, and males. The implications of the findings for clinical care are discussed.
