Derivation and validation of a model predicting the likelihood of vaginal birth following labour induction.

Background: There is high-quality evidence supporting induction of labour (IOL) for a number of maternal and fetal indications. However, one fifth of inductions fail to result in vaginal births, requiring cesarean deliveries. This has negative clinical, emotional and resource implications.

Prediction models for determining the success of labor induction: A systematic review.

Introduction: The purpose of this study was to systematically identify and compare clinical models using universally accessible clinical and demographic factors that were derived and/or validated to predict the success of labor induction with a view to making recommendations for practice.
