Can we predict successful cervical ripening with prostaglandin E2 vaginal inserts?

Purpose Previous studies have suggested that a variety of maternal and obstetrical characteristics may predict successful prostaglandin E2 (PGE2) cervical ripening. However, in most studies women were administered vaginal tablets or gel so scarce is known regarding potential predictors in women administrated slow-release vaginal inserts. We aimed to characterize the response of cervical ripening for labor induction using slow-release PGE2 vaginal insert and to identify predictors for success. Methods A retrospective cohort study in a single center (2013–2015). The association between maternal characteristics at admission and cervical ripening success/failure were explored. Cervical ripening failure was defined as a Bishop’s score
