Association of Counseling and Psychotherapy on Retention in Medication for Addiction Treatment Within a Large Medicaid Population.

OBJECTIVES Buprenorphine/naloxone is an effective medication for the treatment of opioid use disorder. Unlike methadone, which can only be dispensed in federally waived clinics and which must be combined with specific psychosocial treatment, buprenorphine can be dispensed by individual prescribers who have completed an 8-hour training program, with no requirement that patients receive concomitant psychotherapy. The objective of this study is to quantify the association of counseling and psychotherapy on retention in treatment. We also examine the effect of buprenorphine dosage on retention. METHODS We examined a cohort of 4987 members of a not-for-profit managed care organization serving Medicaid members in 41 counties in Pennsylvania. This cohort was selected from all members who had a full year without any medication for opioid use disorder followed by initiation of treatment with buprenorphine/naloxone in 2016 to 2017 and who remained Medicaid eligible for at least 80% of the following 2 years. Outcomes were estimated using inverse probability weighted propensity scores. RESULTS The addition of counseling and psychotherapy within the first 8 weeks of treatment was associated with greater total retention in treatment and there was a dose-response relationship. A 16 mg/d or greater dose of buprenorphine was also associated with greater retention. CONCLUSIONS These results provide support for an integrated approach to treating people with an opioid use disorder, through a combination of buprenorphine pharmacotherapy and targeted counseling and psychotherapy within the first 2 months of treatment.
