About

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.

Full description

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 alongside 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 patient-clinician 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. In collaboration with primary care safety net clinics, the investigators will recruit and randomize 360 participants to (1) IGMV, (2) group acupuncture, (3) both, or (4) neither (usual care, waitlist control). IGMV includes pain education, social and behavioral support, and mind-body approaches (meditation, yoga). Participants randomized to IGMV will initiate groups once enough participants for a cohort have enrolled (8-12 patients). Group acupuncture uses responsive manualization, allowing for a standardized yet individualized treatment. Participants randomized to group acupuncture will initiate 12 weeks of treatment once baseline is completed. Study participants will be asked to complete a total of 3 assessments: a pre-test (baseline), post-test at 3-months, and final follow-up 6 months after baseline.

The investigators will test the hypotheses that compared with usual care, group acupuncture and IGMV improve pain outcomes among racially and ethnically diverse, low-income patients with chronic pain. Our co-primary outcomes of interest are changes in pain impact from baseline to three months (a composite score of pain intensity, pain interference, and physical function) and social support in chronic pain.

Secondary outcomes include: pain interference, pain intensity, physical function, depression, anxiety, sleep, social functioning, global physical, mental, and social well-being using National Institutes of Health (NIH) Patient-Reported Outcomes Measurement Information System (PROMIS®) measures. The investigators will also examine intervention effects on social isolation, internalized stigma of chronic pain, and experiences of discrimination. The investigators will also conduct focus groups and semi-structured interviews to further understand patient experiences with pain management, patient-clinician relationships, and clinical care in primary care safety net settings.

Significance: Multilevel approaches are needed 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. The study receives support from the Helping to End Addiction Long-term® (HEAL) Initiative (https://heal.nih.gov/).

Interventional model: Factorial Assignment

Masking: Single Blind

---

360 participants in 4 patient groups

Usual Care

No Intervention group

Description:

Participants will receive care as usual provided through their primary care providers. Usual care includes medical diagnostic evaluation, analgesic drug therapies, recommendations for physical activity, and sometimes referral to specialist physicians or physical therapy. Usual care was chosen as a comparison arm for this study because it is practical and clinically relevant. Participants randomized to usual care will be put on a waitlist and can access group acupuncture or IGMV after their final study visit.

Group Acupuncture

Experimental group

Description:

Participants randomized to acupuncture will receive 12 weeks of acupuncture treatments delivered in a group setting, dosing similar to prior research. Acupuncture point selection and other treatment details will follow responsive manualization, a protocol developed for the largest clinical trial of group acupuncture to date. A licensed acupuncturist experienced with administering group acupuncture treatments will determine each participant's traditional Chinese medicine diagnosis and administer 8-10 acupuncture needles on distal points of participant's body (below the knees, from the elbows to the hands, and on the head). Duration of assessment, needle placement and retention will be 30-45 minutes. Details of acupuncture treatments (e.g., frequency and duration, traditional Chinese medicine diagnosis, number of needles and points used) will be documented in electronic health records.

Other: Group Acupuncture

Integrative Group Medical Visits (IGMV)

Experimental group

Description:

IGMV will consist of a 12-week program that provides education on the biopsychosocial model of pain and multimodal treatments; physical movement; mindfulness training; and peer support. Non-pharmacologic approaches are based on guidelines on chronic pain management; feedback of experts, staff, and patients; and feasibility with the greatest potential to benefit participants. Participants will receive a binder with educational materials.

Group Acupuncture and IGMV

Experimental group

Description:

Both group acupuncture and IGMV. Along with usual care, participants will be offered weekly group acupuncture treatments and integrative group medical visits as described above.
