Group-Based Integrative Pain Management: Feasibility of a Factorial Randomized Trial in Safety-Net Primary Care.

Purpose: This pilot study tested the feasibility and acceptability of a pragmatic randomized trial evaluating group-based non-pharmacologic approaches to increase access in primary care and improve pain-related outcomes.

Methods: This 2 × 2 factorial trial assessed two 12-week interventions: group acupuncture and integrative group medical visits (IGMVs). Adults with chronic pain lasting ≥3 months were enrolled from safety-net primary care clinics. Participants were randomized to group acupuncture, IGMVs, both, or neither (usual care). We analyzed data using linear mixed models, ANCOVA, and abductive qualitative analysis.

Results: Overall, 44 participants were randomized (25 English-speaking and 19 Spanish-speaking); 59% were female (mean age = 55 years), 21% African American or Black, 52% Latine, 21% non-Latine White, and 5% more than 1 race; and 78% had annual income <$25 000. At baseline, the average duration of chronic pain was 13.0 years, and the mean pain impact score was 36.0 (SD = 6.4). Participants randomized to interventions attended 6 of 12 sessions on average; 89% would participate again; and 86% reported clinically relevant pain improvements versus 20% in usual care (P < .001). Qualitative data revealed substantial barriers to accessing multimodal care and social benefits of group-based models.

Conclusion: Group-based integrative pain management is feasible and acceptable when co-located within safety-net primary care.Clinicaltrials.gov Registration Number: NCT05906784 (http://clinicaltrials.gov/study/NCT05906784).
