  "abstract": "Objectives Until now, there has still been a lack of sufficient evidence on patient-reported outcomes (PROs) measured by the EuroQol-5 Dimension (EQ-5D) in patients with systemic lupus erythematosus (SLE) in China. This study aims to comprehensively assess EQ-5D outcomes and influencing factors in Chinese patients with SLE.Design A multicentre, cross-sectional study based on the Chinese Systemic Lupus Erythematosus Treatment and Research Group registry.Setting 101 hospitals across 27 provinces of China.Participants 1336 patients with SLE.Outcome measures The information on EQ-5D was collected via an online questionnaire. Medical records were obtained from the Chinese Rheumatology Data Centre (CRDC). Clinical influencing factors related to the reported health problems were identified using multivariate logistic regression. Then, each health state was converted into a health utility score based on the Chinese 2014 tariff. Given the ceiling effects, Tobit regression models were used to analyse the factors influencing health utility scores.Results A total of 1336 patients with SLE were included. Of them, 626 patients (46.9%) reported health problems using EQ-5D. The proportions of patients reporting problems in mobility, self-care, usual activities, pain/discomfort and anxiety/depression were 12.80%, 5.24%, 14.90%, 27.47% and 30.46%, respectively. The mean utility score was 0.89 (SD: 0.15), and the mean Visual Analogue Scale (VAS ) score was 76.80 (SD: 16.54). There was a statistically significant correlation (r=0.503, p<0.001) between utility scores and VAS scores. Disease activity, organ damage, poor socioeconomic status, mucocutaneous involvement and high-dose glucocorticoids were associated with health utility scores.Conclusions EQ-5D may be a useful, preference-based PRO measure for SLE and could potentially be integrated into routine clinical monitoring of patients with SLE and applied in economic evaluations in the future.",
