Incremental peritoneal dialysis with days off vs standard-dose peritoneal dialysis: a propensity-matched study (PD holiday)
摘要
The benefits of incremental peritoneal dialysis (IPD) with days off remain controversial. This study aimed to compare the survival rate between IPD with days off and standard-dose peritoneal dialysis (PD).
MethodsParticipants who started continuous peritoneal dialysis (CAPD) between October 1, 2020 and November 30, 2021, in a tertiary hospital in Thailand were enrolled. IPD with two days off (performed 5 days a week) and standard-dose PD (performed every day) were compared using propensity score matching at a 1:1 ratio for baseline characteristics. The primary outcome was 1-year patient survival. One-year PD continuation rate, PD-associated peritonitis rate, admission rate, and weekly Kt/V at 6 weeks, 6 months, and 12 months were analyzed.
ResultsThe 118 eligible patients (37 IPD and 81 standard-dose PD) were included. After propensity score matching, the groups were compared. One-year patient survival rates were comparable between groups, with no statistically significant difference (94.3% vs. 97.4% in the IPD and standard-dose PD groups, respectively; hazard ratio (HR) 2.15, 95% confidence interval (CI) 0.19–23.75). The 1-year PD continuation, PD-associated peritonitis rate, and admission rate were comparable between groups. Total weekly Kt/V over the 12 months showed no significant change over time.
ConclusionIPD with days off appears to be safe and comparable to standard-dose PD in terms of short-term patient survival.
