The impact of vascular access satisfaction on health-related quality of life in patients receiving maintenance hemodialysis: A 2-year follow-up study

Background: Health-related quality of life (HRQoL) has been demonstrated to predict mortality in patients receiving maintenance hemodialysis (MHD). Vascular access (VA) is critical for MHD patients. The aim of this study was to investigate the change in HRQoL among MHD patients with a 2-year follow-up and to explore the impact of VA satisfaction on HRQoL in this population. Methods: 229 MHD patients in two dialysis centers were included in this observational prospective study. VA satisfaction was assessed using the Vascular Access Questionnaire (VAQ). The 36 Item Short-Form Health Survey (SF-36) questionnaire was employed to evaluate HRQoL scores. Multiple logistic regression analysis was used to evaluate the influencing factors of HRQoL. Results: A total of 229 MHD patients were enrolled in the study, and 198 individuals (86.46%) completed the 2-year follow-up. HRQoL decreased statistically significantly from baseline to the 2-year follow-up across all dimensions. Multivariable analyses showed that the overall score, social functioning score, dialysis-related complication score of VAQ influenced HRQoL in the study population. Furthermore, HRQoL total scores and scores on the physical component summary (PCS) and mental component summary (MCS) domains were significantly higher in the satisfied VA group than in the dissatisfied group at baseline. After the 2-year follow-up, patients with a higher level of VA satisfaction reported higher HRQoL than patients with lower VA satisfaction. Conclusion: Our data suggested that VA satisfaction was significantly associated with HRQoL in MHD patients. These findings imply that surgeons and nephrologists should incorporate patient satisfaction into VA surgical decision-making.
