Background and aims
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.
Design
Two-arm open-label randomized trial.
Setting
Two methadone treatment programs (MTPs) in Baltimore, Maryland, USA.
Participants
300 newly-admitted MTP patients were enrolled between September 13, 2011 and March 26, 2014. Their mean age was 42.7 years (SD=10.1) and 59% were males.
Intervention
Newly-admitted MTP patients were randomly assigned to either Patient-centered Methadone Treatment (PCM; n=149) which modified the MTPās 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).
Measurements
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.
Findings
There was no significant difference between PCM and TAU conditions on 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).
Conclusions
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.
