Home Treatment for Individuals Suffering From Severe Addictive Disorders

Home Treatment (HT) has been successfully implemented in adult psychiatry in several countries including Switzerland. Patients with addiction problems were generally excluded even if the latter was not the main diagnosis. On the other hand, community treatments have successfully been established for these individuals. The investigators have recently offered HT to persons with severe addictive disorders which was well accepted. The investigators intend to conduct a pilot study to prepare a large-scale study if successful. The investigators intend to compare HT to treatment as usual (regular inpatient treatment) on a specialized ward with respect to readmission rates during 6 months after discharge. The data show that 70.8% of all readmissions occur during the first 6 months. Therefore, a period of 6 months is considered an adequate time interval to sufficiently answer this pilot study's question.

Hospital-like treatment in patients' home. Caregivers, medical doctors and social workers will make several visits per day to the patients' home. 24/7 contact is available.

clinical outcomes measured with Health of the Nation Outcome scale (HoNOS) scoring 0 (no symptoms) to 48 (high symptom level) and the Brief Symptom Check-List (short form of the Brief Symptom Inventory), scoring 0-53 items (higher score = more symptoms). Measured at the start and end of intervention/hospital treatment.

Patient satisfaction measured with the S-ANQ (https://www.anq.ch/en/), a questionnaire used by all Swiss hospitals to measure patient satisfaction with treatment. The questionnaire includes 6 questions which are marked from 0 not at all satisfied to 5 = very satisfied. Scoring 0 (not at all satisfied) to 30 (very satisfied)
