Study Protocol for Pain Self-Management and Patient-Oriented Buprenorphine Dosing for Pain and Retention in Office-Based Opioid Treatment: A Hybrid Type 1, 2 × 2 Factorial Randomized Controlled Trial.

Chronic pain is a significant factor for patients with opioid use disorder (OUD) contributing to suboptimal retention in buprenorphine treatment, which is a crucial predictor of long-term health outcomes. This study aims to address the critical need for effective interventions targeting chronic pain management within office-based opioid treatment (OBOT) programs. We are conducting a multisite, hybrid type 1, 2 × 2 factorial randomized clinical trial to determine the effectiveness of 2 novel interventions, pain self-management (PSM) and patient-oriented buprenorphine dosing (POD), to decrease pain interference and improve retention in buprenorphine treatment. PSM, a manualized and customizable approach delivered through individual and peer-led group sessions, aims to decrease pain-related symptoms and quality of life. POD involves split dosing of buprenorphine to extend the duration of analgesia to better match its duration of efficacy at managing OUD symptoms, leading to improved retention in buprenorphine treatment. Eligible participants will be randomized into 1 of 4 groups: (1) PSM + POD, (2) PSM + Standard Buprenorphine Dosing, (3) Usual Care + POD, or (4) Usual Care + Standard Buprenorphine Dosing. Usual Care refers to usual care for chronic pain and Standard Buprenorphine Dosing refers to the participant's current dosing regimen. Secondary objectives encompass overall pain reduction, decreased opioid use, improved pain symptom management, and exploration of implementation strategies. The supplemental approved protocol provides comprehensive insights into the procedures and variables being investigated. As part of the HEAL Initiative^®-funded Integrative Management of Chronic Pain and OUD for Whole Recovery (IMPOWR) network, this study aims to fill gaps in behavioral and medication treatments for individuals with co-occurring chronic pain and OUDs, improving pain management and retention in care. Successful outcomes from this trial may inform future larger trials, offering essential evidence for implementation considerations and reimbursement decisions.
