CKD and renal replacement therapy (RRT) are associated with an increased risk for non-elective hospitalizations. The causes for hospitalizations in the pediatric CKD population have not been defined to date. Here, we aimed to analyze the leading reasons for non-elective hospitalizations in the 4C study, a large prospective European cohort of children with CKD.

Material and methods:

Patients aged 6-17 years with CKD stage 3-5 or renal replacement therapy (RRT) followed at 55 centers in 14 countries with at least two study visits were included in the analysis. Data about CKD stage, renal replacement therapy (RRT) and hospitalizations were collected 6-monthly.


A total of 662 patients were followed for a total of 2718 patient-years (PY). A total of 138, 80 and 167 non-elective hospitalizations were documented for patients on conservative therapy (CKD; n=662), dialysis (n=170) and renal transplant (RTx) recipients (n=205), respectively.
The leading causes for non-elective hospitalizations in all groups were infections (44.2%, 44.5% and 48.5% in patients on CKD, dialysis and RTx, respectively). These were followed by non-infectious gastrointestinal conditions (17.4%) in patients on CKD, cardiovascular complications (17.5%; 64.3% hypertension) in patients on dialysis and RTx rejection-related hospitalizations (28.7%) in RTx recipients. Urinary tract infections (UTI) accounted for most of infection-related hospitalization in children on CKD, HD and RTx (62.3%, 35.7% and 44.4%) and peritonitis was the leading cause in patients on PD (62.5%). EBV or CMV infections comprised 13.6% of infection related hospitalizations in RTx.


Infectious diseases represent the leading cause for non-elective hospitalizations in children with CKD and on any RRT. UTIs are the major cause for hospitalizations in most children with CKD. Among patients on RRT, children on PD are at highest risk for hospitalizations due to treatment modality-related infections.
