Determinants of implementation for group medical visits for patients with chronic pain: a systematic review

Despite the critical need for comprehensive and effective chronic pain care, delivery of such care remains challenging. Group medical visits (GMVs) offer an innovative and efficient model for providing comprehensive care for patients with chronic pain. The purpose of this systematic review was to identify barriers and facilitators (determinants) to implementing GMVs for adult patients with chronic pain. The review included peer-reviewed studies reporting findings on implementation of GMVs for chronic pain, inclusive of all study designs. Pubmed, EMBASE, Web of Science, and Cochrane Library were searched. Studies of individual appointments or group therapy were excluded. The Mixed Methods Appraisal Tool was used to determine risk of bias. Data related to implementation determinants were extracted independently by two reviewers. Data synthesis was guided by the updated Consolidated Framework for Implementation Research. Thirty-three articles reporting on 25 studies met criteria for inclusion and included qualitative observational (n = 8), randomized controlled trial (n = 6), quantitative non-randomized (n = 9), quantitative descriptive (n = 3), and mixed methods designs (n = 7). The studies included in this review included a total of 2364 participants. Quality ratings were mixed, with qualitative articles receiving the highest quality ratings. Common multi-level determinants included the relative advantage of GMVs for chronic pain over other available models, the capability and motivation of clinicians, the cost of GMVs to patients and the health system, the need and opportunity of patients, the availability of resources and relational connections supporting recruitment and referral to GMVs within the clinic setting, and financing and policies within the outer setting. Multi-level factors determine the implementation of GMVs for chronic pain. Future research is needed to investigate these determinants more thoroughly and to develop and test implementation strategies addressing these determinants to promote the scale-up of GMVs for patients with chronic pain.
