Safety of a 24‐h‐or‐less Break‐in Period in Elderly Patients Undergoing Urgent‐start Peritoneal Dialysis: A Multicenter Retrospective Cohort Study

Background Several elderly patients with end-stage renal disease (ESRD) had to undergo urgent-start peritoneal dialysis (USPD). This study aimed to determine whether break-in period (BI) within 24 h was feasible in elderly patients undergoing USPD. Methods Patients with ESRD who underwent PD at five hospitals were screened. Patients were divided into the BI <= 24 h and >24 h groups. Complications were compared between the two groups. Multivariate logistic regression model was used to determine whether BI <= 24 h was associated with complications. Results A total of 175 elderly patients were included: BI <= 24 h group, 78; and BI >24 h group, 97. There was no significant difference in the rate of complications between the two groups (all p > 0.05). Furthermore, BI <= 24 h was not an independent risk factor for complications (all p > 0.05). Conclusions Starting PD within 24 h after PD catheter insertion was feasible in elderly ESRD patients.
