Abstract
BACKGROUND: Survival to hospital discharge in neonates born with kidney failure has not been previously described.
METHODS: This was a retrospective, observational analysis of the Pediatric Health Information System (PHIS) database from 2005 to 2019. Primary outcome was survival at discharge; secondary outcomes were hospital and ICU length of stay (LOS). Univariate analysis was performed to describe the population by birth weight (BW) and characterize survival; multivariable generalized liner mixed modeling assuming a binomial distribution and logit link was performed to identify mortality risk factors.
RESULTS: Of 213 neonates born with kidney failure (median BW 2714 g; GA 35 weeks; 68% male), 4 (1.9%) did not receive dialysis or peritoneal dialysis (PD) catheter placement, 152 (72.9%) received PD only, 49 (23.4%) received PD plus extracorporeal dialysis (ECD), and 8 (3.4%) were treated with an undocumented dialysis modality. Median age at dialysis initiation was 7 days; median hospital LOS and ICU LOS were 84 and 69 days, respectively. One-hundred and sixty-two patients (76%) survived to discharge. Non-survivors (n = 51) were more likely to have received ECD and mechanical ventilation, and had a longer duration of mechanical ventilation. Every day of mechanical ventilation increased the mortality odds by 2% (n = 189; adjusted OR 1.02; 1.01, 1.03); in addition, the odds of mortality were 2 times higher in those who received ECD vs. only PD (adjusted OR 2.25; 1.04, 4.86).
CONCLUSIONS: Survival to initial hospital discharge occurs in the majority of neonates born with kidney failure. Predictors of increased mortality included longer duration of mechanical ventilation, as well as the requirement for ECD.
