Abstract/OtherAbstract:
Abstract Aim: The aim of this study was to evaluate the ability of the admission Score for Neonatal Acute Physiology - Perinatal Extension-II (SNAPPE-II) to predict adverse outcome among premature very low birth weight (BW) infants with abnormal Doppler blood flow in the uterus secondary to severe placental insufficiency of early onset. Methods: A total of 86 neonates, weighing between 360 and 1498 g, were studied. Descriptive statistics of the population were reported. The areas under the receiver operating characteristics curves for the SNAPPE-II were calculated. The calibration of the model was assessed using the technique of Hosmer-Lemeshow. Adverse outcome was defined as mortality or the development of the following diagnoses: (1) periventricular-intraventricular hemorrhage (PIH); (2) retinopathy of prematurity stage 3 or 4; (3) periventricular leukomalacia; (4) bronchopulmonary dysplasia; (5) necrotizing enterocolitis (NEC). Results: The SNAPPE-II area under curve was 0.86 (95% CI: 0.78-0.94) for mortality and 0.76 (95% CI: 0.65-0.86) for the prediction of adverse outcomes. Analyzing each morbidity variable, the SNAPPE-II AUC varied between 0.51 for NEC and 0.72 for PIH. Conclusion: SNAPPE-II shows accuracy in the prediction of adverse outcome for this highly selective group of very low BW infants compromised by severe placental insufficiency.
