オピオイド減少の文脈における認知行動療法と慢性疼痛の自己管理：EMPOWER研究

A trained psychologist delivers pain-CBT to individual patients or groups of patients with chronic pain. Group treatment is delivered across 8 weekly sessions that last for 2 hours each. Pain-CBT incorporates interactive discussion, practice of relaxation training, action planning, and home exercises into each session. Pain-CBT is effective for reducing pain intensity, pain catastrophizing, depression and social impacts.

The CPSMP is similar to pain-CBT in format and content but is peer-led, and is effective across pain conditions (e.g., back pain, arthritis) for improving pain and pain self-efficacy. The CPSMP consists of six weekly 2-hour group sessions in which two peer co-leaders provide patient education about pain, effective self-management, pain impacts, and other symptoms from a highly structured manual. Peers are people with chronic pain who live in the communities in which they teach. For this project, at least one peer facilitator per workshop will have had experience with prescription opioid use. Intervention fidelity is determined by having a trained observer with a checklist attend random workshop sessions.

Participants allocated to 'Taper Only' will engage in a physician-guided, patient-centered opioid tapering program without additional behavioral intervention.

Participants allocated to 'Taper Only' will engage in a physician-guided, patient-centered opioid tapering program without additional behavioral intervention.

The national observational arm of the study (the VALUE study) will enroll participants with chronic pain taking at least 10 MEDD daily. No interventions of any kind will be applied and only self-report survey data will be collected for the year following consent. EMPOWER (randomized trial) and VALUE are two independent studies. Data from the two studies will be analyzed separately.

Opioid tapering success was defined as either: 50% reduction in opioid dose (change in MEDD baseline to 12 months) and no significantly increased pain (≤ 1 point increase in PROMIS pain intensity score from baseline to 12 months), or; no opioid dose increase (baseline MEDD to 12 months) and significant pain relief (≥ 2 points decrease in PROMIS pain intensity score). Pain intensity score: Patient self-reported pain intensity on 11 point (0-10) numerical rating scale where a lower score means more pain relief. MEDD: Morphine Equivalent Daily Dose. PROMIS: Patient-Reported Outcomes Measurement Information System.
