PROJECT ABSTRACT Background: The proposed study seeks to address chronic pain disparities in racially diverse, socioeconomically disadvantaged individuals by optimizing multimodal pain management provided in primary care safety net clinics. Multilevel barriers exist in primary care settings where socioeconomically disadvantaged patients are most often treated. Lack of access to multimodal and nonpharmacologic care at the organizational level, and provider bias and other forms of discrimination at the interpersonal level contribute to unequal assessment, treatment, and quality of pain care. Stigmatization cross-cuts all levels and is closely linked with social isolation common among individuals with chronic pain. Group-based models are a promising multilevel approach to increase access to non-pharmacologic therapies, address time constraints that contribute to disparities in pain care, improve interpersonal communication, and provide social support among safety net patients with chronic pain. Methods: This study uses mixed methods and a pragmatic 2x2 randomized factorial trial to test two group-based models: integrative group medical visits (IGMV) and group acupuncture. The study tests the hypotheses that compared with usual care, each study intervention improves pain interference and social isolation (primary outcomes), and that the two combined have synergistic effects mediated by increased social support and decreased impact of intersectional stigma among safety net patients with chronic pain. Study interventions include 12 weekly sessions based on existing protocols tested in primary care safety net settings. IGMV includes pain education, social and behavioral support, and mind-body approaches (meditation, yoga). Group acupuncture uses responsive manualization, allowing for a standardized yet individualized treatment. During the R61 phase, a panel of national experts and patient stakeholders will refine and optimize the structure, process, and content of IGMV aimed at reducing social isolation and intersectional stigma as part of pain management. Interventions will be piloted in 40 English or Spanish speaking patients with chronic pain at two primary care safety net clinics. Study procedures will be tested and adapted for a larger scale trial. In the R33 phase, 360 participants will be recruited from two safety net clinics and randomized to IGMV, group acupuncture, both, or neither. Aim 1 is to determine the effects of study interventions on pain-related outcomes (primary outcomes: pain interference and social isolation). Aim 2 tests social support and stigma as intervention mediators. Aim 3 examines patient experiences with pain management, patient-clinician relationships, and clinical care in primary care safety net settings using qualitative methods. Significance: Multilevel approaches are need to advance health equity in pain management. The proposed study will contribute to knowledge of group-based integrative pain management co-located in primary care to address disparities in pain care for socioeconomically vulnerable populations.

PROJECT NARRATIVE Socioeconomically disadvantaged populations have a high prevalence of chronic pain, exacerbated by social isolation, intersectional stigma, and disparities in pain assessment and treatment options. Effective interventions using a multilevel, biopsychosocial approach are needed to decrease the unequal burden of pain. The proposed study will test group-based integrative models of pain management in primary care safety net clinics to improve pain care for racially and ethnically diverse low-income patients.
