[Court-ordered inpatient psychiatric care in Switzerland. Length of stay and treatment outcome].

Mentally disordered offenders may be convicted to court-ordered psychiatric-psychotherapeutic inpatient care. Based on the concept of a forensic therapeutic community, the treatments of 204 inmates of a medium-security hospital, who presented with psychosis, personality disorders or substance-use disorders, have been assessed. After a median stay of 2.5 years, 56% of the offenders had been transferred to a sheltered educational housing or to an open low-security psychiatric ward. Length of stay was independent of psychiatric diagnosis, yet dependent on the nature of the offense. Having a cluster B personality disorder or a conviction for a sexual offense increased the risk of return to prison. Younger age and offenses without interpersonal violence increased the chances to enter sheltered educational housing.
