Background
Arteriovenous fistula (AVF) is the preferred vascular access for haemodialysis (HD); however, the association between vascular access and quality of life (QOL) is not well-known. We investigate the relationships between HD vascular access and all-cause mortality, health-related quality of life (HRQOL) and depression in a large prospective cohort.
Methods
A total of 1461 patients for whom HD was newly initiated were prospectively enrolled. The initial vascular access types were classified as AVF, arteriovenous graft (AVG) and central venous catheter (CVC). The primary outcome was all-cause mortality and the secondary outcomes were HRQOL, depression and all-cause hospitalisation. Kidney Disease Quality of Life Short Form 36 and Beck’s depression inventory scores were measured to assess HRQOL and depression, respectively.
Results
Of 1461 patients, 314 patients started HD via AVF, 76 via AVG, and 1071 via CVC. In the survival analysis, patients with AVF or AVG showed significantly better survival than those with CVC (P=0.015). The numbers of annual hospitalisation were not different among the groups. The AVF and AVG groups had a significantly higher Kidney Disease Quality of Life Short Form 36 score and a significantly lower Beck’s depression inventory score than the CVC group at 3 months and 12 months after the initiation of dialysis.
Conclusion
Patients with AVF or AVG have a better survival and HRQOL score and are less depressed than those with CVC. These suggest that the choice of vascular access in incident HD patients is important in terms of mortality and quality of life.
