Association of AKI Class Switching With Outcomes
AKI
With regard to most demographic and clinical characteristics, neonates with unveiled AKI were similar to those with AKI diagnosed using uncorrected serum creatinine (Compared with those without AKI, neonates with unveiled AKI were more likely to require invasive mechanical ventilation on postnatal day 14 (81 neonates [75.0%] vs 254 neonates [44.3%]) and have longer hospital stays (median [IQR] stay, 102 [84-124] days vs 90 [71-110] days). There was no difference in mortality between these groups. Neonates with unveiled severe AKI were more likely to require ventilation on postnatal day 14 (33 neonates [82.5%] vs 400 neonates [50.7%]) compared with those without AKI, but we saw no difference in hospital length of stay or mortality (
