One-year follow-up of dual diagnosis patients attending a 4-month integrated inpatient treatment

Eur Addict Res. 2002 Jan;8(1):30-7. doi: 10.1159/000049485.


The purpose of this study was to assess a 4-month inpatient treatment program based on integrated models for patients with substance use and psychiatric disorders (dual diagnosis patients). On admission and at the 1-year follow-up, a consecutive sample of 118 dual diagnosis patients who entered the program were assessed by interview. Eighty-four patients (70.6%) completed the 1-year follow-up interview, reporting less frequent substance use, less severe psychiatric symptoms, a lower rehospitalization rate, and better housing conditions than on admission. Patients diagnosed with a comorbid personality disorder had a better improvement in the frequency of drinking and were less likely to be rehospitalized than patients with schizophrenia or depression. The results suggest that the integrated inpatient program may be a promising treatment approach for dual diagnosis patients. The results await replication in controlled studies that need to include an assessment of outpatient treatment following inpatient programs.
