Quality of Life and Treatment Satisfaction with Pharmacological Interventions in Chinese Adults with Chronic Pain Due to Osteoarthritis
Abstract Background: Aim of this multicenter, observational, cross-sectional study was to evaluate health-related quality of life (HRQoL) and treatment satisfaction of current medications in Chinese knee OA patients. Methods: Brief Pain Inventory (BPI), Treatment Satisfaction Questionnaire (TSQM-1.4), and HRQoL (EQ-5D-5L) were assessed in total of 601 OA of knee patients. Results: Mean score of EQ-5D-5L of patients with BPI-Severity ≥4 was significantly lower than those with BPI-Severity <4. All the scores of TSQM in 4 dimensions were lower in patients with BPI-Severity ≥4 than in those with BPI-Severity <4. Both HRQoL scores and TSQM scores showed a statistically significant decreasing trend with increasing BPI-Severity pain score.Conclusion: Chronic knee OA pain has a significant impact on patients’ HRQoL. More severe patients with OA were less satisfied with current treatments. Trial registration (Clinical Trials identifier): Not applicable
