Suicide prevalence in chemical dependency programs: preliminary data from a national sample, and an examination of risk factors.

Completed suicides over a one year period of time were reported from a nationwide survey of Department of Veteran Affairs medical centers. Of a total of 248 completed suicides, 11 occurred in outpatient substance abuse programs, and an additional 5 occurred among patients receiving combined outpatient substance abuse and psychiatric treatment. There were no inpatient suicides. During this time, there were 7 suicide attempts on inpatient units and 37 suicide attempts in outpatient chemical dependency treatment. The majority of suicides were committed by males who had a primary alcohol addiction (63%). Thirty-eight percent of the sample had a comorbid mood disorder and 38% had a comorbid personality disorder. Risk factors relating to the potential for suicide in chemical dependency programs are discussed.
