Objective: To compare the neonatal outcome (survival, intraventricular hemorrhage and bronchopulmonary dysplasia) of inborn and outborn very-low-birth-weight infants accounting for sociodemographic, obstetric and perinatal variables. Study design: Ninety-one premature infants with birth weights of 750-1250 g delivered between 1990 and 1994 in a hospital providing neonatal intensive care were compared with 76 premature babies delivered in a referring hospital. In the statistical analysis, variables with a statistically significant association with the outcome variables and dissimilar distributions in the two hospitals were identified and entered together with the hospital of birth as explanatory variables in a logistic regression. Results: No statistically significant differences between the outcome variables of the two populations examined were observed, whether before or after accounting for the covariates. The odds ratios (outborns relative to inborns) were 1.18 for mortality, 1.25 for bronchopulmonary dysplasia and 1.53 for severe intraventricular hemorrhage. In the multivariate analyses, respiratory distress syndrome was significantly associated with mortality; both low birth weight and the presence of respiratory distress syndrome were associated with the development of bronchopulmonary dysplasia; the evolvement of severe intraventricular hemorrhage was associated with respiratory distress syndrome, initial low Apgar score, advanced multiparity and delivery at the 28-29th week compared to the 23rd-27th week. Antenatal steroid administration had a protective effect. Conclusion: Our results concur with the notion that a tertiary center is the optimal location for delivery of the high risk neonate. Improvement in medical and nursing care prenatally and at delivery and transportation, including frequent administration of antenatal steroids and earlier administration of surfactant prior to transportation, may minimize the disadvantage of delivery in a referring hospital.
