Background

The aim of this study was to compare long-term survival rates of patients on peritoneal dialysis (PD) who started immediately after catheter insertion without a break-in procedure and those on hemodialysis (HD).

Methods

We conducted a retrospective study including all ESRD patients who started HD or PD between Jan 2005 and Dec 2021. PD catheters were inserted using percutaneous catheter insertion and initiated immediately. All patients were followed up until death, renal transplantation, or the end of the study. Patient survival rates were calculated using Kaplan-Meier analyses.

Results

A total of 379 HD patients and 150 PD patients were included. During followup, death occurred in 34.0% (n=129) of HD and 21.3% (n=32) of PD cases. The survival rates of HD patients were 92.5%, 81.1% and 44.8% at 1, 3 and 10 years. In PD patients, the survival rates were 95.5%, 86.4% and 55.7% at 1, 3 and 8 years. There was no difference in long-term survival between two groups (Fig1A). However, in the first year of dialysis, PD was associated with a greater survival than HD (p=0.007) (Fig1B). Advanced age (defined as ≥60 years) and diabetes were associated with an increase in mortality regardless of dialysis modality (Fig1C). Particularly, the survival rate of non-diabetic PD was higher than that of non-diabetic HD as well as HD and PD patients with diabetes (Fig1D).

Conclusion

There is no difference in long-term survival rate between HD and immediate-start PD, but in the first year of dialysis, PD patients have better survival rate than HD. In particular, in non-diabetic patients, PD seems to have a superior survival rate than HD.
