Among patients who received an arteriovenous fistula (AVF), 90% eventually used that access for hemodialysis, according to researchers.<\/p>\n

If created too early, AVFs may go unused and increase risks for complications like hand ischemia, according to the researchers. If an AVF is created too late, patients may receive a central venous catheter (CVC) instead to start hemodialysis, which is associated with increased mortality and bloodstream infection, the researchers wrote.<\/p>\n
\u201cWith the ageing population and rising numbers of elderly patients starting dialysis, understanding optimal timing of AVF creation has become increasingly urgent,\u201d Heggen and colleagues wrote.<\/p>\n
In a prospective observational study, the researchers evaluated trends in timing of vascular access creation with autologous AVF and CVC among 332 patients aged at least 65 years with ESKD (mean age, 76 years; 77% men) in the European EQUAL cohort study between 2013 and 2023.<\/p>\n
Vascular access timing was classified under three categories:<\/p>\n
\nearly: hemodialysis not initiated within 6 months after AVF creation;<\/li>\n on time: hemodialysis initiated within 6 months of AVF creation; or <\/li>\n late: hemodialysis initiated with CVC within 6 months after AVF creation or initiated with CVC before AVF creation.<\/li>\n<\/ul>\nResults showed 67% of patients received AVFs as their first vascular access. Among the 33% of patients who received a CVC, nearly half received an AVF afterward. <\/p>\n
At the time of hemodialysis initiation, 54% had an AVF and 46% had a CVC.<\/p>\n
AVF creation was considered early for 42% of patients, on time for 32% of patients and late for 26% of patients. <\/p>\n
Notably, 90% of patients with AVFs began receiving hemodialysis within 3 years, indicating high fistula use rates, according to the researchers. <\/p>\n
Overall, the findings suggest most older patients eventually used their AVF for hemodialysis, according to the researchers. However, the potential for unused AVFs and vascular access complications indicate more research is needed to inform vascular access practices, they wrote.<\/p>\n
\u201cThese findings may aid in discussing vascular access options with elderly patients and indicate the need to develop a clinical prediction tool for imminent hemodialysis initiation to guide the timing of vascular access surgery,\u201d the researchers wrote. <\/p>\n
