Characteristics of substance-abusing veterans attempting suicide: A national study

Demographic, diagnostic, and service utilization characteristics of veterans diagnosed with suicide attempt, substance dependence, both, or neither at discharge from Department of Veterans Affairs (DVA) hospitals in fiscal year 1994 (FY94) were compared using the DVA's discharge abstract database. Four groups of veterans were studied: (1) substance-abusing suicidal inpatients (n=1,459), (2) substance-abusing nonsuicidal inpatients (n=123,808), (3) nonsubstance-abusing suicidal inpatients (n=632), and (4) nonsubstance-abusing nonsuicidal inpatients (n=402,906). Substance-abusing suicidal veterans had higher rates of substance abuse than substance-abusing nonsuicidal veterans and mere more psychiatrically disordered than nonsubstance-abusing suicidal veterans. Substance-abusing suicidal veterans had a higher mean number of inpatient treatment episodes and a larger proportion of discharges against medical advice than the other three inpatient groups. Psychiatric and substance use disorders are more prevalent among substance-abusing suicidal veterans than among veterans with only substance use disorders or suicidal conduct.
