The application and influence factors of FACIT Fatigue Scale in SLE patients

Objective To evaluate the application and influence factors of the Functional Assessment of Chronic Illness Therapy (FACIT-Fatigue) scale in patients with systemic lupus erythematosus (SLE). Methods SF-36 questionnaires were used to estimate the health-related quality of life (HRQOL) of SLE patients in Chinese Han population.FACIT-Fatigue scale was applied to measure fatigue.Disease activity was determined by SLE disease activity index (SLEDAI), meanwhile demographic parameters such as gender, disease duration, etc. were recorded. Results A total of 223 patients with SLE were enrolled in the survey.FACIT-Fatigue scale was negatively correlated with SF-36 (P<0.05). FACIT-Fatigue scale of patients with SLE were correlated with education, erythrocyte sedimentation rate (ESR), C3, and SLEDAI score (P<0.05). The degree of bodily pain, the status of mental health and the amount of complement C3 were the independent factors of FACIT-Fatigue (P<0.1). Conclusion FACIT-Fatigue scale is related to disease activity, quality of life, age and ESR in patients with SLE.There fore, reduce the disease activity and improve the quality of life of SLE patients may be helpful to reduce the fatigue of patients with SLE.
