[Opioid Maintenance for Patients in Inpatient Long-Term Rehabilitation Treatment - which Patients Benefit?]

Objective Patients from opioid maintenance treatment (OMT) may taper off from opioids during rehab treatment. It is investigated whether this option improves treatment outcomes in particular for those patients who are affected by psychiatric or somatic comorbidity, or by social problems. Methods Multicenter study with 4 rehab units. Patient characteristics and treatment outcomes were collected retrospectively. There were n=227 patients who were admitted to treatment while still receiving OMT, and n=156 who were opioid free. Results With regard to regular completion of rehab treatment, an interaction was observed between status at admission and diagnosis of affective, neurotic and anxiety disorders, and between status and previous rehab treatment experience. If admitted in an abstinent status, patients who had never entered rehab, and patients with affective or anxiety disorders showed decreased regular completion rates, while they showed increased completion rates if tapered off during treatment. There was no interaction between initial status and acute life crisis (release from prison, homelessness), somatic diagnoses, or number of stabilizing social factors. Conclusion Admission while still receiving opiate maintenance could be helpful for patients with psychiatric comorbidity and for patients who had previously been reluctant to enter rehab treatment.
