Introduction and objective: In obstetrics induction of labour (IOL) is common medical intervention. The aim of the study was to evaluate factors predicting a successful labour induction and to analyse the connection between components of Bishop score and the result of the induced labour. Material and methods: This was a retrospective cohort study of 214 labour inductions conducted at Gynecology and Obstetrics Ward of Solec Hospital in Warsaw from January to December 2019. Type of delivery, whether vaginal or caesarean, was the outcome. Results: The prevalence of failed induction of labour was 28.97%. The main indications for caesarean delivery (CD) were impending fetal asphyxia and failure to progress in labor. Multiparity (p=0.0015), BMI <30 of the patient (95% CI: 28.577, 29.756), mature cervix (95% CI: 7.657, 8,237), IOL with oxytocin infusion (p=0.0025) and such indications as gestational diabetes mellitus, premature rupture of membranes, LGA and less fetal movement sensation (p=0.0067) are predictors of successful IOL. Among all parameters examined in the Bishop score the cervical shortening correlates best with the prediction of successful IOL (Phi Coefficient 0.187). Conclusions: The strongest predictors for succesful IOL are parity and degree of shortening of the cervix.
