Background Limited data exist on rehospitalization in paediatric dialysis patients. The objective of this study was to identify indications, rates and risk factors for 30-day readmissions in this population. Methods We used a prospective multinational, multicentre cohort study of haemodialysis (HD) and peritoneal dialysis (PD) patients discharged between July 2017 and July 2018. Readmission was identified as repeat hospitalization within 30 days of a prior (index) admission. Potentially preventable readmissions were clinically related to the initial admission. Early readmissions were those occurring within 7 days of discharge. The primary outcome was 30-day readmission. Secondary outcomes included potentially avoidable and early readmissions. Results A total of 54 (31%) of 176 patients (102 PD, 74 HD) had at least one readmission; 84 (18%) discharges were followed by readmission. PD and HD patients had similar readmission rates {30.4% versus 31.1%; hazard ratio [HR] 1.06 [95% confidence interval (CI) 0.61–1.81]}. Compared with PD, HD patients had a significantly shorter time to readmission (8 versus 14 days; P =.019), higher early readmission rates (46% versus 18%; P =.010) and risk [odds ratio (OR) 3.87 (95% CI 1.35–11.11)]. Main readmission causes were dialysis access–related non-infectious complications (31%) and access infections (22.7%); 47% of readmissions were potentially avoidable. Lower haemoglobin levels were
