Data on more than 38,500 Canadian patients found that those who got hemodialysis via a central line catheter into a large vein were 80% more likely to die during the first year compared with patients who received peritoneal dialysis or dialysis via an arteriovenous graft. The risk of infection also was lower among those who received dialysis through the fistula or graft than those who had it through the central line, according to the study in the Journal of the American Society of Nephrology.
