Intra- or extrauterine transport? Comparison of neonatal outcomes using a logistic model.

In a retrospective study a comparative analysis of mortality by way of transport (maternal, neonatal, or not referred) was performed on 163 liveborn newborns with a gestational age of less than 32 wk or a birth weight of less than 1500 g. The occurrence of potential mortality risk factors in the subgroups was taken into account. Of these, caesarean section, sex, Apgar score, intubation after delivery, birth weight and gestational age showed a relationship with mortality. Logistic regression analysis regarding the relationship between mortality and way of transport revealed that mortality in the neonatal transport group was significantly higher than in the maternal transport group, taking into account the confounding risk factors sex, caesarean section, fetal growth retardation, birth weight and gestational age.
