Overview and Feasibility of a Novel Transdisciplinary Integrative Approach to High Impact Chronic Pain in Vermont.

Background/objective: Pain is one of the most common chronic conditions in the US, estimated to affect 20.9% of the population (51.6 million people). We evaluated the Partners Aligned in Transformative Healing (PATH) program at University Medical Center's Comprehensive Pain Program clinic. Feasibility, initial clinical and financial results were assessed to inform payers' support for PATH, an integrative transdisciplinary program within a bundled payment format.

Methods: Participants completed a multi-week program including integrative therapies, with empirically validated assessment surveys administered at the beginning and end of the program. Insurance claims data were analyzed 12 months pre- and post-program. Statistical significance of pre-post differences was assessed by paired T-tests with < 0.05.

Results: Between June 2019 and August 2022, 170 individuals enrolled in PATH, 151 (88.8%) completed the program, and 121 participants completed outcome surveys. Participants were predominately White, non-Hispanic (98%), female (76%), with an average age of 49.8. All participant-reported clinical outcomes (PROs) showed statistically significant improvement from baseline to final assessment, and some but not all were clinically significant. PEG subscale of average pain interference, enjoyment of life, and interference with general activity each decreased. The T-scores for the following domains of PROMIS-29 decreased: Pain interference; fatigue; sleep disturbance; anxiety, and depression. The PROMIS-29 domains of overall physical function and social roles and activities mean T-scores increased. Per Member Per Month (PMPM) total cost of care decreased by $462 (18%). Emergency room utilization for all diagnoses decreased by 457 visits/1000 patients (65%), and for pain-related diagnoses by 194 visits/1000 patients (67%) during the observation period.

Conclusions: Results suggest that the PATH Program is a feasible and acceptable model that shows initial effectiveness relative to short-term patient-reported clinical outcomes and shows signs of durability in both utilization and financial outcomes at 1 year. The results support continued study including a multi-site RCT.
