Main findings
There are three main findings of this large prospective screening study
for adverse pregnancy outcome. First, about 60% of antepartum
stillbirths are related to placental dysfunction and in more 90% of
such cases the fetuses are SGA. Second, in screening for placental
dysfunction related stillbirth by a combination of maternal risk
factors, EFW and UtA-PI utilising the competing risks model for
SGA7, the predictive performance is similar to that
achieved in screening by a specific logistic regression model for
placental dysfunction related stillbirth1. Third, the
performance of screening by the competing risks model for SGA is by far
superior to the RCOG guideline for the investigation and management of
the SGA fetus 3.
