Purpose
Immediate-start peritoneal dialysis (PD) has emerged as a strategy for patients in need of urgent dialysis. However, the ideal timing for initiating this procedure remains uncertain. In this study, we aimed to compare complications and outcomes between immediate-start PD and conventional-start PD.
Methods
We performed a two-center retrospective cohort study between 1 January 2015 and 31 May 2020. Patients who underwent PD were divided into immediate-start PD (without break-in period) and conventional-start PD group (break-in period within at least 14 days). The primary outcomes were the incidence of the mechanical complications and infectious complication. The secondary outcomes were technique failure and patient survival.
Results
A total of 209 patients (106 in the immediate-start PD group and 103 in the conventional-start PD group) were included. Immediate-start PD had significantly lower catheter malfunction or migration rate compare with conventional-start PD (2.8% vs. 15.5%, p = 0.003) but comparable rates of dialysate leaks, pleuroperitoneal leaks, and hemoperitoneum. Infectious complications (exit-site infection and peritonitis) were similar between groups. Technique survival was comparable (7.5% vs. 4.8%, p = 0.22), while immediate-start PD exhibited lower mortality rates (0.9% vs. 13.6%, p = 0.001).
Conclusion
Immediate-start PD appears to be a viable option for patients in need of urgent dialysis, with reduced catheter complications and comparable infectious complications and technique survival when compared to conventional-start PD.
