Health Resource Utilization and Cost Impact of Integrative Medicine Services for Newly Diagnosed Chronic Pain Patients.

Abstract

Background: Integrative medicine (IM) is the healing-oriented practice of medicine that emphasizes the relationship between practitioner and patient. It considers the whole person, their environment, lifestyle, and social and cultural factors. It is evidence based and makes use of all appropriate therapies, conventional and complimentary. Objective: To evaluate the impact of IM services on health outcomes and care costs of chronic pain management patients compared with standard care. Methods: This article uses University of New Mexico hospital billing data from 10/2016 to 09/2019 to identify patients with nervous system or musculoskeletal pain. A total of 1,304 patients were matched using propensity scores into IM services (treatment: 652) and standard care (control: 652) cohorts for difference-in-differences analysis. The patients were matched based on age, sex, race, zip code, insurance type, ICD-10s, prescriptions, health care events, and medical claim costs. Results: Patients who used IM services had better health outcomes and lower costs at 3-month, 6-month, and 12-month follow-up. At the 12-month follow-up, the IM group showed a 19% decrease in utilization of inpatient care, a 37% decrease in Emergency Department utilization, and an 11.3% reduction in claim costs compared with the control group. Conclusion: Patients who utilize IM services as part of chronic pain management have overall lower health care costs and better health outcomes. Unfortunately, in the health system studied, less than 3% of patients utilize these services. Promotion of and education about IM services should be aimed at both patients and their providers.
