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

Abstract: 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.

    Risk of incident mild cognitive impairment and dementia soon after leaving incarceration among a US Veteran population

    Abstract: Objectives: Increasing numbers of older adults are reentering community following incarceration (i.e., reentry), yet risk of incident neurodegenerative disorders associated with reentry is unknown. Our objective was to determine association between reentry status (reentry vs never-incarcerated) and mild cognitive impairment (MCI) and/or dementia. Methods: This nationwide, longitudinal cohort study used linked Centers for Medicare & Medicaid Services and Veterans Health Administration data. Participants were aged 65 years or older who experienced reentry between October 1, 2012, and December 31, 2018, with no preincarceration MCI/dementia, compared with age-matched/sex-matched never-incarcerated veterans. MCI/dementia was defined by diagnostic codes. Fine-Gray proportional hazards models were used to examine association. Results: This study included 35,520 veterans, mean age of 70 years, and approximately 1% women. The reentry group (N = 5,920) had higher incidence of MCI/dementia compared with the never-incarcerated group (N = 29,600; 10.2% vs 7.2%; fully adjusted hazard ratio [aHR] 1.12; 95% CI 1.00-1.25). On further investigation, reentry was associated with increased risk of dementia with or without prior MCI diagnosis (aHR 1.21; 95% CI 1.06-1.39) but not MCI only. Discussion: Transition from incarceration to community increased risk of neurocognitive diagnosis. Findings indicate health/social services to identify and address significant cognitive deficits on late-life reentry. Limitations include generalizability to nonveterans.
