Automated and continuous ambulatory peritoneal dialysis have similar outcomes

We compared survival and death-censored technique survival in patients on automated peritoneal dialysis (automated dialysis) or on continuous ambulatory peritoneal dialysis. All 4128 patients from the Australia and New Zealand Dialysis and Transplant Registry who started peritoneal dialysis over a 5-year period through March 2004 were included. Times to death and death-censored technique failure were analyzed by Cox proportional hazards models while a conditional risk set model computed technique failure. Compared to patients treated entirely with continuous ambulatory peritoneal dialysis, automated peritoneal dialysis patients were more likely to be young, Caucasian, have marginally lower body mass index, and were less likely to have baseline cardiovascular disease or diabetes. Using univariate and multivariate analysis, our study showed there were no significant differences in patient survival and death-censored technique failure between the two types of peritoneal dialysis modalities
