Patient Perceptions of Vascular Access and Quality of Life in Maintenance Hemodialysis: A Multicenter Study on Patient-Centered Outcomes

<b>Background:</b> Vascular access is a core component of hemodialysis and may influence both clinical outcomes and patient-reported quality of life. This study examined the association between vascular access type and quality of life among patients receiving maintenance hemodialysis in multiple nephrology centers. <b>Methods:</b> We conducted a multicenter, cross-sectional observational study of 152 adults with end-stage kidney disease undergoing hemodialysis in public and private dialysis units in the Attica region, Greece (January-May 2022). Data were collected using a demographic/clinical questionnaire, the 36-Item Short Form Health Survey (SF-36), the Dialysis Patient Satisfaction Questionnaire (SDIALOR), and the Missoula VITAS Quality of Life Index (MVQOLI). Multivariable linear regression models were fitted for SF-36 and MVQOLI domain scores. <b>Results:</b> Most participants reported being very (40.8%) or quite (53.3%) satisfied with their current vascular access, and 69.5% considered an arteriovenous fistula (AVF) the most appropriate option. SF-36 scores were generally lower than those reported for the general population, except for the mental health domain. Compared with AVF, permanent catheter use was associated with lower SF-36 physical functioning scores, and graft use was associated with lower vitality scores. Lower vascular access satisfaction was consistently associated with lower HRQoL: compared with being "very" satisfied, being "quite" satisfied was associated with lower general health, vitality, social functioning, mental health, and lower PCS/MCS scores, while being "a little/not at all" satisfied was associated with lower general health and worse bodily pain scores. On MVQOLI, living alone and lower access satisfaction were associated with lower interpersonal relationships, transcendence/spirituality, and overall quality-of-life scores, while obesity was associated with lower function scores. <b>Conclusions:</b> Vascular access type, particularly AVF versus catheter, is associated with meaningful differences in quality of life among hemodialysis patients. Patient satisfaction with access and sociodemographic characteristics should be considered in patient-centered access planning and follow-up.
