| Abstract: | Vascular access‐related infection is an important adverse event in home hemodialysis (HHD). We hypothesize that errors in self‐cannulation or manipulation of dialysis vascular access are associated with increased incidence of access‐related infection. We conducted a retrospective cohort study of all prevalent HHD patients at the University Health Network. All vascular access‐related infections were recorded from 2006 to 2013. Errors in dialysis access were ascertained by nurse‐administered vascular access checklist. Ninety‐two patients had completed at least one vascular access audit. Median HHD vintage was 2.3 (0.9–5.0) years in patients with appropriate vascular access technique and 5.8 (1.5–9.4) years in patients with erroneous vascular access technique. The overall rate of infection between patients with and without appropriate vascular access technique was similar (0.27 and 0.28 infections per year, P = 0.166). Among patients who were identified with errors in dialysis access manipulation, patients with five or more errors were associated with higher rate of access‐related infection (mean of 0.47 vs. 0.16 infection per patient‐year, P < 0.001). The use of vascular access audit is a feasible strategy, which can identify errors in vascular access technique. Patients with a longer median HHD vintage are associated with higher risk of inappropriate vascular access technique. Patients with multiple errors in vascular access technique are associated with a higher risk of dialysis access‐related infection. Prospective evaluation of the impact of vascular access audit on adverse vascular access events is warranted. |
