Abstract

Introduction: The hemodialysis population is aging, worldwide. In Israel, more than half of the dialysis population is older than 68 years. The policy for vascular access among this population is still a matter of debate, with several studies demonstrating conflicting results. This study compared vascular access outcomes across age groups (<65, 65–75, >75 years) in a single hemodialysis center in Israel. Methods: This was a retrospective, single center analysis of all vascular accesses created in adult hemodialysis patients in our institution, from January 1, 2006, through December 31, 2012. Patient characteristics, primary and secondary access failure, and complications were collected from electronic medical records. Follow-up was until death or up to 5 years. Results: A total of 612 vascular accesses created among maintenance hemodialysis patients were included, of which 196 were in patients >75 years, 184 in patients 65–75 years, and 232 in patients <65 years. Mean age of the >75 years group was 80.5 ± 4.3 years and 60.7% were men. Vascular access site was the most important predicator for primary access failure (odds ratio for primary failure of radiocephalic arteriovenous fistula was 3.5 (95% CI 2.1–6), whereas age did not affect the primary failure rate (odds ratio 1.5, p = 0.648). Radiocephalic fistulas were more prone to secondary failure than other vascular access sites were. Complications were slightly more common in the oldest group. Eight percent of the patients >75 years died before access was used. Conclusions: In our cohort, age did not affect vascular outcomes, whereas VA site seemed to be the most important parameter in primary and secondary VA failures. Our results support considering VA on an individual basis and supply valuable information regarding complication and failure rates of VA among patients >75 years.
