title: Survival and Neurodevelopmental Outcomes of Very Low Birth Weight Infants in a Regional Core Hospital in Kochi, Japan.
abstract: We sought to clarify the survival and neurodevelopmental outcomes of very low birth weight infants (VLBWIs) and to identify risk factors for death or neurodevelopmental impairment (NDI) in VLBWIs at our hospital. The total study population was 217 infants born in 2005-2012 weighing 1,500 g. We compared their outcomes with those from previous reports analyzed the causes of death. Risk factors for death after discharge or NDI were evaluated by a multivariate logistic regression analysis. The incidences of death or NDI reported revealed in this study and the database of Neonatal Research Network of Japan were 25.3% and 19.6% (p＝0.039), respectively. The main causes of death before discharge were intraventricular hemorrhage, sepsis, and persistent pulmonary hypertension of the newborn. The significant risk factors for death after discharge or NDI were early gestational age (weeks) and periventricular leukomalacia (adjusted odds ratio [95% confidence interval, p-value], 0.72 [0.54-0.94, 0.017] and 6.90 [1.35-38.25, 0.021], respectively). These factors must be addressed in order to improve treatment strategies for VLBWIs.
