Estimating success of vaginal birth after caesarean section in a regional Australian population: Validation of a prediction model

Abstract

BACKGROUND: Following a primary caesarean section (CS), women must decide between attempted vaginal birth after caesarean (VBAC) and elective repeat caesarean section (ERCS) in subsequent pregnancies. Both options carry potential morbidity and mortality for mother and child, with the most feared being uterine rupture and its consequences. In attempts to reduce morbidity, several predictive nomograms have been developed to assist in delivery mode decisions. AIM: To assess the validity of the predictive nomogram developed by Grobman et al. in our regional Australian population. MATERIALS AND METHODS: In our retrospective analysis, patients at term, with one previous CS who had a trial of labou..
