Comparison of Patient Hospitalization in Chronic Peritoneal Dialysis and Hemodialysis: A Pediatric Multicenter Study

Abstract

Patient hospitalization was compared in 207 pediatric patients (age < or = 15 years at the start of dialysis) on chronic peritoneal dialysis (CPD) (127 patients) or center hemodialysis (HD) (80 patients), treated in 17 dialysis centers during the period 1989 to 1994, and followed up for at least three months. The hospitalization rate was expressed as hospital days per patient-month, and was calculated on the overall period of treatment and separately for the first and second year. Since the age at start of dialysis markedly differed between CPD (8.2 +/- 4.7 years) and HD (11.2 +/- 2.9 years) patients (with no HD patient younger than five years), results are separately presented in three patient groups: CPD patients aged < 5 years (A); CPD patients aged five to 15 years (B); HD patients (C). The duration of hospitalization was subdivided according to the following different causes: routine (monitoring of dialysis adequacy), complications of the modality, patient primary renal disease, and other causes. The results are presented in Table 1. A statistically significant difference in total days hospitalized was found between each of the two groups of CPD patients and the HD patients; the results for hospitalization for dialysis-related complications were higher in the group of younger children on CPD, while the difference between the two age-matched groups of patients on CPD and HD was not significant.
