Perinatal factors associated with neonatal mortality in very low birth weight infants: a multicenter study.

Abstract:

INTRODUCTION:Objectives. To assess risk factors associated withneonatal mortality in very low birth weight (VLBW) infants (< 1500 g) and the impact of the administration of antenatal corticosteroids. POPULATION AND METHODS:Retrospective analysis of a VLBW infant cohort from 26 tertiary care and teaching sites member of the South American Neonatal Network (NEOCOSUR), which includes Argentina, Brazil, Chile, Paraguay, Peru, and Uruguay, conducted between 2000 and 2011 on 11 455 records. Maternal and neonatal characteristics and morbidity were compared between deceased VLBW infants and those who survived to discharge. Outcome measures associated with neonatal mortality were established by logistic regression. The effect of antenatal corticosteroids on neonatal morbidity and mortality was estimated using the matching method. RESULTS:The neonatal mortality rate was 22.3%, and variability among sites was elevated. Factors that were independently associated with a lower mortality of VLBW infants included the administration of antenatal corticosteroids (OR: 0.49, 95% CI: 0.43-0.54), a better birth weight Z-score (OR: 0.63, 0.61-0.65), arterial hypertension (OR: 0.67, 0.58-0.77), and C-section (OR: 0.75, 0.65-0.85). The matching method allowed reducing the risk of death by 38% in association with antenatal corticosteroids. CONCLUSIONS:Major perinatal factors were identified in association with neonatal mortality in VLBW infants, and the impact of antenatal corticosteroid use in the NEOCOSUR Network was demonstrated. INTRODUCCIÓN:Objetivos. Evaluar los factores de riesgo asociados a la mortalidad neonatal en recién nacidos de muy bajo peso (RNMBP, < 1500 g) y el impacto de la administración antenatal de corticoides. POBLACIÓN Y MÉTODOS:Análisis retrospectivo de una cohorte de RNMBP de 26 centros perinatales terciarios y universitarios de la Red Neonatal Sudamericana (NEOCOSUR), que incluye Argentina, Brasil, Chile, Paraguay, Perú y Uruguay, entre 2000 y 2011, y que cuenta con 11455 registros. Las características maternas, neonatales y la morbilidad se compararon entre los RNMBP que murieron y los sobrevivientes hasta el alta. Las variables asociadas con la muerte neonatal se determinaron mediante regresión logística. Se estimó el efecto del corticoide prenatal sobre la morbimortalidad neonatal utilizando el método de pareamiento. RESULTADOS:La tasa de mortalidad neonatal fue de 22,3% con una elevada variabilidad entre los centros. Los factores independientemente asociados a menor mortalidad de los RNMBP fueron la administración de corticoides prenatal (OR 0,49; IC 95%: 0,43-0,54), mejor puntaje Z del peso de nacimiento (OR 0,63; 0,61-0,65), hipertensión arterial (OR 0,67; 0,58-0,77) y cesárea (OR 0,75; 0,65-0,85). Mediante pareamiento, el riesgo de muerte se redujo en 38% asociado a los corticoides prenatales. CONCLUSIONES:Se identificaron importantes factores perinatales asociados con la mortalidad neonatal en RNMBP y se demostró el impacto de la administración de corticoides prenatales en la Red NEOCOSUR.
