Adding Self-Care Complementary and Integrative Health Therapies to Care for Chronic Pain: The Assessing Pain, Patient Reported Outcomes and Complementary Health (APPROACH) Study

BACKGROUND: Health care systems and insurers are expanding coverage for practitioner-delivered and self-care complementary and integrative health (CIH) therapies for chronic pain. OBJECTIVES: To determine if combining practitioner-delivered and self-care CIH therapies (PD/SC-CIH) improves pain outcomes more than practitioner-delivered CIH (PD-CIH) therapies alone. RESEARCH DESIGN: Pragmatic nonrandomized trial. Structural nudges and the availability of CIH therapies were used as a surrogate to randomization. SUBJECTS: Of 3306 veterans with chronic musculoskeletal pain at 18 medical centers in the Veterans Health Administration between March 2021 and March 2023. MEASURES: PD-CIH therapies included acupuncture, chiropractic care, or massage therapy. Participants in the PD/SC-CIH arm also received yoga, mindfulness/meditation, and/or Tai Chi/Qigong. The primary outcome was the change in pain-related functional interference at 6 months. RESULTS: Pain interference improved in both arms (-0.62 and -0.70), with 39.5% and 41.1%, respectively, achieving clinically meaningful improvement with no difference between arms in improvement in pain interference: -0.12 (-0.28 to 0.05). At 6 months, more participants in the PD/SC-CIH arm reported their use of CIH therapies specifically led to perceived improvements across 4 global patient-centered measures: pain (11%; 5%-18%); fatigue (28%; 17%-40%); mental health (24%; 14%-35%); and overall well-being (27%; 18%-35%). CONCLUSIONS: Both approaches to offering CIH therapies were equally associated with improvements in pain interference among this large cohort with real-world CIH therapy engagement. More patients in the PD/SC-CIH arm perceived that their use of CIH therapies improved multiple health dimensions. Patients with chronic musculoskeletal pain should be encouraged to add self-care CIH therapies and health care systems should expand their availability.
