A comparison of buprenorphine and psychosocial treatment outcomes in psychosocial and medical settings.

ABSTRACT: BACKGROUND:Facing an epidemic of opioid-related mortality, many government health departments, insurers, and treatment providers have attempted to expand patient access to buprenorphine in psychosocial substance use disorder (SUD) programs and medical settings. METHODS:With Missouri Medicaid data from 2008 to 2015, we used Cox proportional hazard models to estimate the relative hazards for treatment attrition and SUD-related emergency department (ED) visits or hospitalizations associated with buprenorphine in psychosocial SUD programs and medical settings. We also tested the association of buprenorphine with hours of psychosocial treatment during the first 30?days of psychosocial SUD treatment. The analytic sample included claims from 7606 individuals with an OUD diagnosis. RESULTS:Compared to psychosocial treatment without buprenorphine (PSY), the addition of buprenorphine (PSY-B) was associated with a significantly reduced hazard for treatment attrition (adjusted hazard ratio: 0.67, 95% CI: 0.62-0.71). Among buprenorphine episodes, office-based (B-OBOT), outpatient hospital (B-OPH), and no documented setting (B-PHA) were associated with reduced hazards for treatment attrition when compared to the psychosocial SUD setting (B-PSY) (adjusted hazard ratios: 0.27, 95% CI: 0.24-0.31; 0.46, 95% CI: 0.39-0.54; 0.70, 95% CI: 0.61-0.81). Compared to B-PSY, B-OBOT and B-PHA were associated with significantly reduced hazards for a SUD-related ED visits or hospitalization (adjusted hazard ratios: 0.59, 95% CI: 0.41-0.85; 0.53, 95% CI: 0.36-0.78). There was no significant difference between B-PSY and B-OPH or B-PSY and PSY in hazard for an SUD-related ED visit or hospitalization. CONCLUSIONS:Our findings support the conclusion that adding buprenorphine to Medicaid-covered psychosocial SUD treatment reduces patient attrition and SUD-related ED visits or hospitalizations but that buprenorphine treatment in office-based medical settings is even more effective in reducing these negative outcomes. Policy-makers should consider ways to expand buprenorphine access in all settings, but particularly in office-based medical settings. Buprenorphine treatment in an unbilled setting was associated with an increased hazard for patient attrition when compared to treatment in billed medical settings, indicating the importance of Medicaid-covered provider visits for patient retention.

Project description:ImportanceExpansion of opioid use disorder treatment is needed, particularly in rural communities.ObjectiveTo evaluate technology-assisted buprenorphine (TAB) efficacy (1) over a longer period than previously examined, (2) with the addition of overdose education, and (3) among individuals residing in rural communities.Design, setting, and participantsTwo parallel, 24-week randomized clinical trials were conducted at the University of Vermont between February 1, 2018, and June 30, 2022. Participants were adults with untreated opioid use disorder from nonrural (trial 1) or rural (trial 2) communities. These trials are part of a programmatic effort to develop TAB protocols to improve treatment availability in underserved areas.InterventionsWithin each trial, 50 participants were randomized to TAB or control conditions. Participants in the TAB group completed bimonthly visits to ingest medication and receive take-home doses via a computerized device. They received nightly calls via an interactive voice response (IVR) system, IVR-generated random call-backs, and iPad-delivered HIV, hepatitis C virus (HCV), and overdose education. Control participants received community resource guides and assistance with contacting resources. All participants received harm reduction supplies and completed monthly assessments.Main outcomes and measuresThe primary outcome was biochemically verified illicit opioid abstinence across monthly assessments. Secondary outcomes included self-reported opioid use in both groups and abstinence at bimonthly and random call-back visits, treatment adherence, satisfaction, and changes in HIV, HCV, and overdose knowledge among TAB participants.ResultsFifty individuals (mean [SD] age, 40.6 [13.1] years; 28 [56.0%] male) participated in trial 1, and 50 (mean [SD] age, 40.3 [10.8] years; 30 [60.0%] male) participated in trial 2. Participants in the TAB group achieved significantly greater illicit opioid abstinence vs controls at all time points in both trial 1 (85.3% [128 of 150]; 95% CI, 70.7%-93.3%; vs 24.0% [36 of 150]; 95% CI, 13.6%-38.8%) and trial 2 (88.0% [132 of 150]; 95% CI, 72.1%-95.4%; vs 21.3% [32 of 150]; 95% CI, 11.4%-36.5%). High abstinence rates were also observed at TAB participants' bimonthly dosing visits (83.0% [95% CI, 67.0%-92.0%] for trial 1 and 88.0% [95% CI, 71.0%-95.0%] for trial 2). Treatment adherence was favorable and similar between trials (with rates of approximately 99% for buprenorphine administration, 93% for daily IVR calls, and 92% for random call-backs), and 183 of 187 urine samples (97.9%) tested negative for illicit opioids at random call-backs. iPad-delivered education was associated with significant and sustained increases in HIV, HCV, and overdose knowledge.Conclusions and relevanceIn these randomized clinical trials of TAB treatment, demonstration of efficacy was extended to a longer duration than previously examined and to patients residing in rural communities.Trial registrationClinicalTrials.gov Identifier: NCT03420313.

Project description:Despite the benefits associated with longer buprenorphine treatment duration (i.e., >180 days) (BTD) for opioid use disorder (OUD), retention remains poor. Research on the impact of co-occurring psychiatric issues on BTD has yielded mixed results. It is also unknown whether the genetic risk in the form of polygenic scores (PGS) for OUD and other comorbid conditions, including problematic alcohol use (PAU) are associated with BTD. We tested the association between somatic and psychiatric comorbidities and long BTD and determined whether PGS for OUD-related conditions was associated with BTD. The study included 6686 individuals with a buprenorphine prescription that lasted for less than 6 months (short-BTD) and 1282 individuals with a buprenorphine prescription that lasted for at least 6 months (long-BTD). Recorded diagnosis of substance addiction and disorders (Odds Ratio (95% CI) = 22.14 (21.88-22.41), P = 2.8 × 10-116), tobacco use disorder (OR (95% CI) = 23.4 (23.13-23.68), P = 4.5 × 10-111), and bipolar disorder (OR(95% CI) = 9.70 (9.48-9.92), P = 1.3 × 10-91), among others, were associated with longer BTD. The PGS of OUD and several OUD co-morbid conditions were associated with any buprenorphine prescription. A higher PGS for OUD (OR per SD increase in PGS (95%CI) = 1.43(1.16-1.77), P = 0.0009), loneliness (OR(95% CI) = 1.39(1.13-1.72), P = 0.002), problematic alcohol use (OR(95%CI) = 1.47(1.19-1.83), P = 0.0004), and externalizing disorders (OR(95%CI) = 1.52(1.23 to 1.89), P = 0.0001) was significantly associated with long-BTD. Associations between BTD and the PGS of depression, chronic pain, nicotine dependence, cannabis use disorder, and bipolar disorder did not survive correction for multiple testing. Longer BTD is associated with diagnoses of psychiatric and somatic conditions in the EHR, as is the genetic score for OUD, loneliness, problematic alcohol use, and externalizing disorders.
