Tele-collaborative outreach to rural patients with chronic pain: pragmatic effectiveness trial protocol for the CORPs study.

Background: Despite the increased availability of evidence-based treatments for chronic pain, many patients in rural areas experience poor access to services. Patients receiving care through the VA may also need to navigate multiple systems of care.

Objective: To examine the effectiveness of a remotely delivered collaborative care intervention for improving pain interference among veterans with high-impact chronic pain living in rural areas.

Design: We will conduct a four-site pragmatic effectiveness trial of remotely delivered collaborative care for high-impact chronic pain. Participants (n = 608) will be randomized to the Tele-Collaborative Outreach to Rural Patients (CORPs) intervention or to minimally enhanced usual care (MEUC). Participants randomized to CORPs will complete a biopsychosocial assessment and five follow-up sessions with a nurse care manager (NCM), who will collaborate with a consulting clinician to provide personalized recommendations and care management. CORP participants will also be invited to a virtual 6-session pain education group class. Participants randomized to MEUC will receive a one-time education session with the NCM to review available pain services. All participants will complete quarterly research assessments for one year. The primary study outcome is pain interference. This trial will oversample veterans of female birth sex and minoritized race or ethnicity to test heterogeneity of treatment effects across these patient characteristics. We will conduct an implementation process evaluation and incremental cost-effectiveness analysis.

Discussion: This pragmatic trial will test the real-world effectiveness of a remotely delivered collaborative care intervention for chronic pain. Study findings will inform future implementation efforts to support potential uptake of the intervention.
