Substance abuse and psychiatric illness: treatment experience.

The purpose of this paper is to describe an outpatient dual-diagnosis treatment program and 1-year clinical outcome and hospital utilization data. Subjects were 118 consecutive admissions to the Seattle Veterans Affairs (VA) Medical Center's Dual Disorders program over the period from June 1, 1992, to August 31, 1994. Program eligibility requirements included having a current substance use disorder and an active non-substance-related major Axis I disorder (typically major depression, post-traumatic stress disorder [PTSD], bipolar disorder, or schizoaffective disorder). The treatment frame involved group-based programming (including support, medications management, and psychoeducation), routine urine drug screening, and crisis interventions. Results showed that subjects averaged 1.5 non-substance-related Axis I psychiatric disorders (54% involving psychotic symptoms) and 1.8 active substance use disorders. Patients stayed engaged in treatment for a median of 217 days, with 60% of patients having no positive drug screens, and the overall sample having a 40% reduction in the number of inpatient bed days in the year after intake. Conclusions were that, for a number of patients with comorbid disorders, psychiatric stabilization and cessation of substance use can be accomplished within an outpatient treatment frame that averages two completed clinical contacts per week.
