Abstract
Background/Objectives: Korean medicine healthcare (KMHC), a form of traditional medicine including acupuncture and herbal medicine, is widely utilized by patients with intervertebral disc disease (IVDD). With the increasing use of real-world evidence (RWE) in the medical field, this study aims to derive RWE on KMHC utilization and its associated factors in patients with IVDD. Methods: Data from 495 individuals who received outpatient healthcare for IVDD regardless of the purpose such as treatment, examination, rehabilitation, monitoring, or prescription were analyzed using the 2022 Korea Health Panel Survey (KHPS). Multinomial logistic regression analyses were performed to identify factors associated with healthcare use for IVDD. Regression models were constructed by sequentially adding predisposing, enabling, and need factors following Andersen's behavioral model. All statistical analyses accounted for the complex survey design of the KHPS using survey sampling weights. Results: Individuals aged 45-59 years were less likely to use both KMHC and conventional medicine healthcare (CMHC) for IVDD compared to those aged 19-44 years (adjusted odds ratio [95% confidence interval], 0.28 [0.09, 0.89]). People with disabilities showed lower utilization of both KMHC and CMHC for IVDD compared to those without disabilities (0.27 [0.09, 0.81]). Individuals who were employed (2.37 [1.06, 5.3]) or perceived their health status as fair (3.05 [1.17, 8]) or poor/very poor (6.13 [2.04, 18.45]) were more inclined to use both KMHC and CMHC for IVDD. Individuals who engaged in regular physical activities (2.65 [1.19, 5.9]) or had shoulder joint diseases (3.71 [1.22, 11.29]) or other spine-related diseases (2.63 [1.16, 5.96]) were more inclined to use KMHC-only for IVDD. Conclusions: This study identified significant demographic and health-related factors influencing KMHC utilization for IVDD. These findings emphasize the need for tailored healthcare policies regarding KMHC for IVDD for effective resource distribution.
