Background: The KDOQI (Kidney Disease Outcomes Quality Initiative) recommends not using Arterio-Venous-Fistulas (AVFs) for Hemodialysis treatment (HD) within 1-month after creation because earlier cannulation (≤ 14 days) leads to reduced fistula survival.Methods: This retrospective cohort study was conducted in 205 patients, who started maintenance HD with a Radial-Cephalic-AVF (RC-AVF) based on institutional guidelines similar to the KDOQI recommendations. Configuration of the RC-AVF was standardized. Postoperative day from creation to first RC-AVF cannulation was abbreviated as POD. The primary endpoint was the first occurrence of a Vascular Access (VA) event (thrombectomy, surgical revision, or percutaneous transluminal angioplasty). Hazard ratios and 95% confidence intervals for the primary endpoint were determined. The cut-off POD for a VA event was calculated using the Receiver-Operating Characteristic curve and a Diagnostic Performance plot.Results: The primary endpoint occurred in 85 patients (41%) during 52 months (median). The cutoff POD to predict a VA event was <22 days. Cumulative incidence rates of VA endpoints were 53% and 31% for PODs ≤ 21 and >21 days, respectively (p=0.0008). A POD ≥ 22 days reduced the risk of a VA event by 52% compared with a POD <22 days. No significant difference in a VA event was seen for a POD ≤ 14 and a POD 15-21 days. A POD ≥ 22 days exerted a 60% reduction in a VA event compared with a POD ≤ 14 days.Discussion: The time from creation until the first cannulation of a RC-AVF should be set at more than 3 weeks. This finding provides a good example of the KDOQI recommendations.
