Abstract Background As significant advances in the field of treatment for rheumatoid arthritis (RA), there is a great need to identify the healthcare outcomes such as treatment satisfaction and health-related quality of life (HRQoL) of patients with various treatment options. This study aims to identify the difference in the treatment satisfaction and HRQoL of patients with RA using different treatment options, by comparing the treatment satisfaction and HRQoL in patients with RA treated with tofacitinib and adalimumab in real-world settings in Korea, using propensity score methods. Methods In this non-interventional, multicenter, cross-sectional study (NCT03703817), a total of 410 patients with RA diagnosis were recruited in 21 university-based hospitals throughout Korea. The treatment satisfaction and HRQoL were assessed using the Treatment Satisfaction Questionnaire for Medication (TSQM) and EQ-5D questionnaires self-reported by the patients. This study compared outcomes between two drug groups in unweighted, greedy matching, and stabilized inverse probability of treatment weight (IPTW) samples using propensity score. Results In all three samples, tofacitinib group showed higher convenience domain of TSQM than that in the adalimumab group, but not effectiveness, side effects, and global satisfaction domains. Multivariable analysis using the covariates of demographic and clinical characteristics of the participants also showed consistent results in TSQM. No statistical difference in EQ-5D-based HRQoL was identified between two drug groups in all three samples. Conclusions This study identified that tofacitinib shows higher treatment satisfaction in the convenience domain of TSQM rather than adalimumab, suggesting that various factors such as drug formulation, route or frequency of administration, and storage can have an impact on the treatment satisfaction, especially the convenience domain. These findings may be useful to patients and physicians when determining treatment options. Trial registration ClinicalTrials.gov, NCT03703817. |
