Measures of central tendency were calculated to describe the cohort stratified by the primary dialysis-related diagnosis including acute kidney injury requiring dialysis (AKI-D), stage 5 chronic kidney disease (CKD 5), hyperammonemia, and other causes. The primary outcome was death during the initial hospitalization.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Results<\/jats:title>\n                    <jats:p>For the 405 neonates in this cohort, AKI-D (57%) was the most common dialysis-related diagnosis, followed by CKD 5 (29%) and hyperammonemia (11%). Most neonates (58%) had a birth weight between 2500 and 3500\u00a0g. The most common initial neonatal dialysis modality was continuous kidney replacement therapy (CKRT) with (35%) or without extracorporeal membrane oxygenation (ECMO) (36%). Only 26% of neonates received peritoneal dialysis (PD) as their initial dialysis modality. Thirty percent of neonates received more than one dialysis modality. The overall mortality was 50% (59% in AKI-D and 41% in CKD 5). Withdrawal of care was reported as the most common reason for death. The odds of death were lower for neonates with AKI-D receiving PD as the initial modality when compared to CKRT (aOR 0.28, 95% CI 0.09\u20130.84) or CKRT with ECMO (aOR 0.24, 95% CI 0.10\u20130.58), but this association was not seen in neonates with CKD 5.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Conclusions<\/jats:title>\n                    <jats:p>This multicenter, contemporary neonatal dialysis cohort shows increased use of CKRT as the initial dialysis modality but also shows that the mortality of neonates on dialysis remains high.
