The chief aim of our work has been to create a computer Cardiotocographic
Assessment System (CAS) and thus eliminate the intra- and inter-observer
variability of the visual assessment of the cardiotocogram (CTG), and to
improve the assessment of the CTGs to the standard of the most experienced
obstetricians. The purpose of this paper is to present the accuracy of the
prediction of fetal outcome obtained by the CAS and to compare it with 4
experienced obstetricians' accuracy. Fifty CTGs from the last 30 min. of
labor were assessed as normal or pathological by the computer and by the
obstetricians. The condition of the newborn was evaluated from the
one-minute Apgar score, the umbilical artery pH and standard base excess,
and the need for resuscitation. The accuracy of the CAS was significantly
better than the accuracy of the obstetrician obtaining the best result. We
conclude that the development of a computer-aided cardiotocographic
assessment system is worthwhile.
