A cross-sectional assessment of health-related quality of life in Chinese patients with chronic hepatitis c virus infection with EQ-5D.

ABSTRACT

BACKGROUND: Hepatitis C virus (HCV) infection is one of the most common liver infections, with a decrement in HRQoL of HCV patients. This study aims to assess Health-related quality of life (HRQoL) in Chinese patients with chronic HCV infection, and to identify significant predictors of the HRQoL in these patients of China. METHODS: In this cross-sectional observational study, treatment-naïve Han ethnic adults with chronic HCV infection were enrolled. Adopting European Quality of Life scale (EQ-5D) and EuroQOL visual analogue scale (EQ-VAS) were used to qualify HRQoL. Results were reported in descriptive analyses to describe sociodemographic and clinical characteristics. Multiple linear regression analysis was applied to investigate the associations of these variables with HRQoL. Binary logistic regression analysis was performed to identify associations of these variables with HRQoL by dimensions of EQ-5D. RESULTS: Nine hundred ninety-seven patients were enrolled in the study [median age 46.0 (37.0, 56.0) years; male 54.8%]. Mean EQ-5D index and EQ-VAS score were 0.780 ± 0.083 and 77.2 ± 14.8. Multiple Linear regression analysis showed that income (< 2000 RMB, ß = - 0.134; 2000-4999 RMB, ß = - 0.085), moderate or severe symptoms of discomfort (more than one symptoms, ß = - 0.090), disease profile (cirrhosis, ß = - 0.114), hyperlipidemia (ß = - 0.065) and depression (ß = - 0.065) were independently associated with EQ-5D index. Residence (the west, ß = 0.087), income (< 2000 RMB, ß = - 0.129; 2000-4999 RMB, ß = - 0.052), moderate or severe symptoms of discomfort (more than one symptoms, ß = - 0.091), disease profile and depression (ß = - 0.316) were the influencing factors on EQ-VAS. Binary logistic regression indicated that disease profile and clinical depression were the major influencing factors on all five dimensions of EQ-5D. CONCLUSIONS: In this cross-sectional assessment of HCV patients in China, we indicated HRQoL of Chinese HCV patients. Significant negative associations between HRQoL and sociodemographic and clinical factors such as moderate or severe symptoms of discomfort, disease profile and depression emerged. We have to focus on optimally managing care of HCV patients and improving their HRQoL. TRIAL REGISTRATION ClinicalTrials.gov identifier NCT01293279. Date of registration February 10, 2011.
