Abstract：【Objective】 To explore the predictive efficacy of cervical maturity score (Bishop score) combined with modified vaginal birth after cesarean (VBAC) score for VBAC failure. 【Methods 】A total of 400 parturients undergoing trial of labor after cesarean section who delivered in our hospital from January 2020 to May 2023 were selected. According to whether vaginal delivery was successful, the parturients were divided into the success group (n=295) and the failure group (n=105). The Bishop score, modified VBAC score and general data were compared between the two groups. Multivariate stepwise Logistic regression model was used to analyze the influencing factors of VBAC failure. Receiver operating characteristic (ROC) curve was used to analyze the predictive efficacy of Bishop score, modified VBAC score and their combination for VBAC failure. 【Results 】The Bishop score and modified VBAC score in the success group were higher than those in the failure group (P<0.05), the previous vaginal delivery rate was higher than that in the failure group (P<0.05), the time since the last cesarean section was longer than that in the failure group (P<0.05), and the estimated fetal weight was lower than that in the failure group (P<0.05). Multivariate stepwise Logistic regression model analysis showed that previous vaginal delivery history, time since last cesarean section, estimated fetal weight, Bishop score and modified VBAC score were the influencing factors of VBAC failure (P<0.05). ROC curve analysis showed that the AUC of Bishop score and modified VBAC score for predicting VBAC failure was 0.831 and 0.832, respectively, and the AUC of their combination for predicting VBAC failure was 0.916. 【Conclusion】The combination of Bishop score and modified VBAC score has high predictive efficacy for VBAC failure.
