Evaluation of a Model for the Treatment of Combined Mental Illness and Substance Abuse: The Bellevue Model for Peer-Led Treatment in Systems Change

Abstract The present study evaluated a model program at Bellevue Hospital Center incorporating a peer-led self-help (PLSH) approach which can be applied to bring about systems-level change in a variety of settings where persons with dual diagnosis are encountered. A total of 461 consecutive MICA inpatient admissions were evaluated to compare the PLSH unit with two standard psychiatric units. The PLSH program was associated with a higher rate of acceptance of aftercare referral (93% vs. 74%) and aftercare attendance (52% vs. 30%) among patients with no prior psychiatric hospitalizations (N = 111). In addition, the PLSH program appeared to benefit chronically impaired MICA patients (N = 350) or those with a history of prior psychiatric hospitalizations, as they were more likely to accept referral to aftercare treatment than were chronic patients discharged from the standard psychiatric units (96% vs. 81%). Such a program, when more widely applied, could yield decreased recidivism and considerably lower medi...
