♦ Background Dialysis-related infections are the commonest cause of catheter loss and transfer to hemodialysis. Surface modifications of the catheter that reduce infections are of major importance.♦ Objective The efficacy of silver-ion treated catheters in reducing dialysis-related infections was tested.♦ Methods The study design was a prospective, randomized controlled trial. Patients were implanted with either a silver-treated study catheter or a control catheter. Prospective collection of data included infectious complications and catheter survival.♦ Results The subject groups were comprised of 67 silver-treated catheters and 72 control catheters. Demographic characteristics of the study and control groups were equal. Exit-site infection rates for the study group and control group (0.52 and 0.45 episodes/patient-year of dialysis respectively) were not different by Poisson regression analysis (p> 0.4). Peritonitis rates were identical for the two groups (0.37 episodes/patient-year) and were not different by Poisson analysis (p> 0.9). Antibiotic-free intervals between infections for the study and control groups were not significantly different for exit-site infections (p= 0.58), peritonitis (p= 0.44), or both infections combined (p= 0.47). Actuarial analyses showed no differences between the groups in the probability of remaining free of exit-site infection (p> 0.2) or peritonitis (p> 0.7). Similarly, catheter survival was not significantly different between the groups (p> 0.6).♦ Conclusion Surface modification of catheters with ion beam implantation of silver produced no clinical effect with respect to reducing dialysis-related infections. |
