“…The greater BFR variability in North America may be one reason why the AVF survival/facility median BFR relationship was stronger in North America than in Japan and EUR/ANZ. It is difficult to assess our results with those published previously which have been variable regarding patient-level BFR and AVF survival [22,23]. However, our study has provided the largest international sample for testing these relationships with detailed and extensive adjustments to allow greater generalizability and greater ability to account for treatment-by-indication bias.…”

Background: Vascular access (VA) guidelines recommend the native arteriovenous fistula (AVF) as VA of first choice for chronic hemodialysis patients. AVF management is important in hemodialysis patient care. AVF survival is associated with various physical factors, but the effects of dialysis treatment factors upon AVF survival are still not clear. Methods: Study patients were treated at 498 dialysis facilities participating in the Dialysis Outcomes and Practice Patterns Study (DOPPS) 2 or 3 (2002-2007). Analyses included 1,183 incident hemodialysis patients (on dialysis ≤7 days and using an AVF at study entry) and 949 prevalent patients (on dialysis >7 days at DOPPS entry and using a new AVF created during study observation). AVF survival was modeled from the study entry date for incident patients and date of first AVF use for prevalent patients. Predictors of primary and final AVF survival were compared across Japan, North America and Europe/Australia/New Zealand (EUR/ANZ) with adjustments for patient characteristics. Results: No meaningful relationship was seen between AVF survival and various physician and staff practices. However, patients with prior catheter use displayed higher rates of primary and final AVF failure. Final AVF failure rates were higher in facilities with higher median blood flow rates (BFR). They were also greater in North America and EUR/ANZ than in Japan, but this difference was substantially attenuated after accounting for regional differences in facility median BFR. Conclusion: AVF longevity differed according to the DOPPS region, and was related to prior patient catheter use and facility BFR practice. Further longitudinal studies may help demonstrate meaningful associations between VA-handling skill and patency.

“…Women may present with smaller-caliber arteries and may therefore be expected to have lower AVF patency rates than men. However, Caplin et al 4 showed that arterial and venous diameters 39,40 Yes Can be used as prognostic tool or prompt re-evaluation in short-term benefit but paucity of data/largest trial found reduced thrombosis rate but no effect on cumulative patency…”

“…39 A prior report correlated flows of Ͻ200 mL/min with reduced primary and secondary patency. 40 AVFs with low flows after anastomosis could therefore be identified as "at risk" and may thus warrant further investigation in the theatre or by more intensive follow-up regimens.…”
