Longitudinal Utilization of Invasive Pain Treatment Procedures Among Veterans with Chronic Pain Following Use of Whole Health Services and Complementary and Integrative Health Therapies.

Objective: To assess whether Whole Health, a system of care that emphasizes non-pharmacological approaches for chronic pain management, is associated with changes in downstream utilization of invasive pain treatment procedures. Methods: Longitudinal retrospective cohort analysis of VHA administrative data. A total of 53,412 Veterans with chronic pain were identified between April and September 2018, with 584 initiating Whole Health and 3794 initiating a complementary and integrative health (CIH) therapy independent of Whole Health (CIH-only). Whole Health included use of coaching, personal health planning, and other services including CIH referral. CIH therapies included chiropractic care, acupuncture, massage therapy, yoga, Tai Chi/Qigong, and meditation. Propensity score matching was used to estimate expected rates of invasive pain treatment procedures 0-3, 4-12, and 13-18 months after initiating Whole Health or CIH-only compared to similar Veterans who had not engaged in either. Results: Overall, 14% of the population were female, 11% had received prior spine injections, 3.3% had received surgery, and 0.4% had an implantable spinal stimulator. Whole Health use was associated with 42% (-61% to -17%) lower utilization of invasive pain procedures at three months compared to matched patients who did not use Whole Health. This reduction was attenuated at 18 months: 22% (-39% to -5%). CIH-only was associated with 18% (-29% to -4%) lower utilization at three months compared with matched patients, but differences were minimal at 18 months: 1% (-9% to 9%). Discussion: Whole Health care, including CIH therapies, may help patients interrupt patterns of escalating and invasive pain care.
