Objectives: Hemodialysis is the most used renal replacement modality for end-stage renal disease patients. Dialysis patients are usually assessed for quality of life (QoL) but smiling was never studied. Duchenne smile is a genuine expression of joy, associated with better survival in some groups of the general population. In this study, we aimed to evaluate whether the smile of dialysis patients can predict their QoL and mortality. Methods: All hemodialysis patients in Saint-George Hospital were included in this prospective study. Patients were interviewed using the Health-Related QoL questionnaire and followed for 10 days for smile screening. Those who smiled more than 34% of time were considered as smiling, then followed for death over 2 years. Results: Overall, 71 patients were studied. Duchenne smile was associated with death at 1 and 2 years (HR = 0.194 [95% CI 0.039-0.958], p = .044) but not with sex or diabetes. Smiling showed a statistically significant correlation with older age, fewer hospitalizations, vitality, physical component score, several QoL scores and general health. Conclusions: A simple observation of patients' Duchenne smile by nephrologists in hemodialysis units can give an idea about their QoL and 2-year survival.
