Background: Induction of labor is one of the most common obstetric interventions. This study peruses Bishop Score value and maternal and fetal characteristics to prediction of successful induction.

Materials and Methods: in this prospective cross-sectional study, 271 full-term pregnant women reffered to Persian Gulf Martyrs’ hospital for deliveryin 2013.They consecutively entered into the study with convenience sampling method until sample size was completed. The effect of components and total Bishop Score were evaluated on success of induction. Bishop score was used to determine vaginal examination by finger. Data were analyzed by using SPSS statistical software version 18 and statistical tests including chi square, independent sample t test and ROC curve was used.

Results: Of 271 women, in 180 of them, delivery started by induction. At induced group 78.9 percent had vaginal delivery and 21.1 percent had cesarean section. The important component of Bishop Score in prediction of successful delivery induction was cervical dilatation. Bishop Score sensitivity was 52.8 percentfor diagnosis of normal vaginal delivery, Positive predictive value was 90.4 percent and its negative predictive value was 30.9 percent. ROC curve showed that overall accuracy of Bishop Score was more than 6 for normal vaginal delivery (95% confidence interval= 0.59-0.78, P value=0.0001).

Conclusion: The findings of this study showed that Bishop Score of 6 and more parity and gestational age was effective in prediction of successful delivery induction. And it seems that Bishop Score, particularly cervical dilatation is an appropriate index for prediction of successful delivery by induction.
