AbstractThere is a new emphasis on tailoring appropriate vascular access for hemodialysis to patients and their life-plans, but there is little known about the optimal use of newer devices such as early-cannulation arteriovenous grafts (ecAVG), with studies utilising them in a wide variety of situations. The aim of this study was to determine if the outcome of ecAVG can be predicted by patient characteristics known pre-operatively. This retrospective analysis of 278 consecutive ecAVG with minimum one-year follow-up correlated functional patency with demographic data, renal history, renal replacement and vascular access history. On univariate analysis, aetiology of renal disease, indication for an ecAVG, the number of previous tunnelled central venous catheters (TCVC) prior to insertion of an ecAVG, peripheral vascular disease, and BMI were significant associates with functional patency. On multivariate analysis the number of previous TCVC, the presence of peripheral vascular disease and indication were independently associated with outcome after allowing for age, sex and BMI. When selecting for vascular access, understanding the clinical circumstances such as indication and previous vascular access can identify patients with differing outcomes. Importantly, strategies that result in TCVC exposure have an independent and cumulative association with decreasing long-term patency for subsequent ecAVG. As such, TCVC exposure is best avoided or minimised particularly when ecAVG can be considered.

Highlights Abstract Background: In pediatric patients, intravenous placement success may be related to predetermined vascular access difficulty. The study purpose was to examine validity and reliability of the 6-item Pediatric Intravenous Difficulty Score. Methods: We determined if a tool that assesses pediatric intravenous difficulty was associated with clinical outcomes of peripheral attempts (criterion validity), hypotheses regarding patients’ age, race, and medical diagnosis (construct validity), and reliability of difficulty levels. Results: In 596 episodes of peripheral intravenous attempts, first-attempt success, overall success, and number of staff attempting access were associated with level of intravenous access difficulty by tool score. The tool met hypothesized construct validity criteria, and in multivariable modeling, the tool was reliable based on difficulty levels of 2 user groups. Conclusions: The 6-item Pediatric Intravenous Difficulty Score has criterion and construct validity and is reliable over time among clinicians with different levels of expertise in peripheral vascular access.

Abstract Background We describe differences for probability of receiving a fistula attempt, achieving fistula use, remaining catheter-free and the rate of access-related procedures as a function of sex. Methods Prospectively collected vascular access data on incident dialysis patients from five Canadian programs using the Dialysis Measurement Analysis and Reporting System to determine differences in fistula-related outcomes between women and men. The probability of receiving a fistula attempt and the probability of fistula use were determined using binary logistic regression. Catheter and fistula procedure rates were described using Poisson regression. We studied time to fistula attempt and time to fistula use, accounting for competing risks. Results We included 1446 (61%) men and 929 (39%) women. Men had a lower body mass index (P < 0.001) and were more likely to have coronary artery disease (P < 0.001) and peripheral vascular disease (p < 0.001). A total of 688 (48%) men and 403 (43%) women received a fistula attempt. Women were less likely to receive a fistula attempt by 6 months {odds ratio [OR] 0.64 [95% confidence interval (CI) 0.52–0.79]} and to achieve catheter-free use of their fistula by 1 year [OR 0.38 (95% CI 0.27–0.53)]. At an average of 2.30 access procedures per person-year, there is no difference between women and men [incidence rate ratio (IRR) 0.97 (95% CI 0.87–1.07)]. Restricting to those with a fistula attempt, women received more procedures [IRR 1.16 (95% CI 1.04–1.30)] attributed to increased catheter procedures [IRR 1.50 (95% CI 1.27–1.78)]. There was no difference in fistula procedures [IRR women versus men 0.96 (95% CI 0.85–1.07)]. Conclusion Compared with men, fewer women undergo a fistula attempt. This disparity increases after adjusting for comorbidities. Women have the same number of fistula procedures as men but are less likely to successfully use their fistula.
