BACKGROUND: The present study investigated whether or not the effect of treatment setting (inpatient or outpatient) on 6-mo follow-up substance use varied for suicidal and non-suicidal patients. In particular, the study tested the hypothesis that treatment setting would have no differing effect for non-suicidal participants, but for suicidal participants, inpatient setting would be more closely associated with positive outcomes than the outpatient setting. METHODS: A national sample of patients presenting for treatment of substance use disorders in the Veterans Administration health care system was selected to participate in the study. A total of 1,289 participants provided complete data on psychiatric and substance-related problems at baseline and 6-mo follow-up. RESULTS: At baseline, 4% (n = 53) of the sample reported having made a suicide attempt within the past 30 days. Those who reported a suicide attempt were no more likely to have been treated in an inpatient setting than in an outpatient setting. A significant interaction between baseline suicide attempt and treatment setting was found, such that non-suicidal patients reported similar patterns of substance use when treated in inpatient or outpatient settings, but suicidal patients were significantly more likely to have better substance-related outcomes at 6-mo follow-up if they were treated in inpatient compared with outpatient settings. CONCLUSIONS: Suicidal patients displayed substantial improvement after substance use disorders treatment and seem particularly responsive to treatment in inpatient settings.
