BACKGROUND: This study was performed to investigate the feasibility of incremental peritoneal dialysis (iPD) in older patients.
METHODS: In this retrospective cohort study, we enrolled peritoneal dialysis (PD) patients with age ≥ 60 years old at our center from 2008 to 2017. The patients were divided into two groups based on the daily PD exchanges: iPD group (≤3 × 2 L exchanges), and full dose group (≥4 × 2 L exchanges). Kaplan-Meier curves and multivariate Cox regression models were applied to evaluate the risks of anuria and mortalities between groups.
RESULTS: A total of 238 patients (186 in full dose group and 52 in iPD group) were enrolled. The mean age was 67.8 ± 5.7 years, and 45.8% were females. The baseline glomerular filtration rate was 4.15 ± 2.39 mL/min/1.73 m2 . Multivariate Cox regression models showed that patients in the iPD group patients had significantly decreased risk of anuria (hazard ratio [HR], 0.44; 95% confidence interval [CI], 0.24-0.81; p = 0.008), and all-cause mortality (HR, 0.59; 95% CI, 0.36-0.98; p = 0.04). Additionally, the incidence of peritonitis was significantly lower in the iPD group than that in the full dose group (0.115 vs. 0.197 episodes per person-year, p = 0.03) during the 36 months of PD commencement.
CONCLUSION: Older patients with iPD were independently associated with better preservation of residual kidney function and survival outcomes. Moreover, iPD regimens are also associated with reduced incidence of peritonitis. The iPD strategy might offer a feasible option for older patients.
