Patient-centered methadone treatment: a randomized clinical trial.

Abstract

Methadone patients who discontinue treatment are at high risk of relapse, yet a substantial proportion discontinue treatment within the first year. We investigated whether a patient-centered approach to methadone treatment improved participant outcomes at 12 months following admission, compared with methadone treatment-as-usual. Two-arm open-label randomized trial. Two methadone treatment programs (MTPs) in Baltimore, MD, USA. Three hundred newly admitted MTP patients were enrolled between 13 September 2011 and 26 March 2014. Their mean age was 42.7 years [standard deviation (SD) = 10.1] and 59% were males. Newly admitted MTP patients were assigned randomly to either patient-centered methadone treatment (PCM; n = 149), which modified the MTP's rules (e.g. counseling attendance was optional), and counselor roles (e.g. counselors were not responsible for enforcing clinic rules) or treatment-as-usual (TAU; n = 151). The primary outcome was opioid-positive urine test at 12-month follow-up. Other 12-month outcomes included days of heroin and cocaine use, cocaine-positive urine tests, meeting DSM-IV opioid and cocaine dependence diagnostic criteria, HIV risk behavior and quality of life and retention in treatment. There was no significant difference between PCM and TAU conditions in opioid-positive urine screens at 12 months [adjusted odds ratio = 0.98; 95% confidence interval (CI) = 0.61, 1.56]. There were also no significant differences in any of the secondary outcome measures (all Ps > 0.05) except Quality of Life Global Score (P = 0.04; 95% CI = 0.01, 0.45). There were no significant differences between conditions in the number of individual or group counseling sessions attended. (Ps > 0.05). Patient-centered methadone treatment (with optional counseling and the counselor not serving as the treatment program disciplinarian) does not appear to be more effective than methadone treatment-as-usual.
