739: Examination of Factors Associated with Treatment Satisfaction in Patients with Chronic Pain

Topic: Clinical Science
Subtopic: Non-specific to any diagnosis, Treatment/management

Background and Aims: Chronic pain is often intractable and treatment requires a significant amount of time and effort. However, patient satisfaction is often not commensurate with treatment contribution. Patient satisfaction is difficult to obtain with treatment efficacy in cases of chronic pain. However, patient satisfaction with treatment can affect treatment strategy and prognosis. This study aimed to examine the factors associated with treatment satisfaction in patients with chronic pain using a pain-related scale.

Methods: The participants were patients with chronic pain (n = 495; men/women, 179/316; age, 65.3 ± 15.7 years) who visited our outpatient pain clinic between 2014 and 2024 and filled-out the questionnaire at the first consultation, and after three and six months; among them, 299 subjects (men/women, 94/205; age, 65.5 ± 14.8 years) filled-out the questionnaire after one year. We calculated changes in scores on the numeric rating scale (NRS), Athens insomnia scale, pain disability assessment scale, hospital anxiety and depression scale, pain catastrophizing scale (PCS), and 25-question geriatric locomotive function scale (GLFS-25). Single correlation analysis (Spearman’s rank correlation coefficient) was performed to assess satisfaction. Multiple regression analysis (enter method) was performed using items that were found to be significantly correlated in the single correlation analysis as independent variables and satisfaction as the dependent variable. For each test, the significance level was set to 5%.

Results: In the multiple regression analysis, variables identified as independent of patient satisfaction were as follows: at three months, the EQ-5D (standardized β= −0.145) and GLFS-25 scores (β= 0.139) were extracted (adjusted R2 = 0.185). At six months, the GLFS-25 score was the sole significant factor (β= 0.120, adjusted R2 = 0.319). At one year, the minimum NRS score was identified (β= 0.169, adjusted R2 = 0.256). The variance inflation factor of the independent variable was less than 10, and no multicollinearity was observed. For all the models, the variance inflation factors (VIFs) of the independent variables were <10, confirming the absence of multicollinearity.

Conclusions: Musculoskeletal disorders were associated with treatment satisfaction after three and six months. The improvement in musculoskeletal disorders could improve treatment satisfaction, even in patients with chronic pain whose pain did not improve sufficiently.
