!Introduction: This study aimed to determine the effects of induction of labour in late-term pregnancies on the mode of delivery, maternal and neonatal outcome. Methods: We retrospectively analyzed deliveries between 2000 and 2014 at the University Hospital of Cologne. Women with a pregnancy aged between 41 + 0 to 42 + 6 weeks were included. Those who underwent induction of labour were compared with women who were expectantly managed. Maternal and neonatal outcomes were evaluated. Results: 856 patients were included into the study. The rate of cesarean deliveries was significantly higher for the induction of labour group (33.8 vs. 21.1 %, p < 0.001). Aside from the more frequent occurrence of perineal lacerations (induction of labour group vs. expectantly managed group = 38.1 % compared with 26.4 %, p = 0.002) and all types of lacerations (induction of labour group vs. expectantly managed group = 61.5% vs. 52.2 %, p = 0.021) in women with vaginal delivery, there were no significant differences in maternal outcome. Besides, no differences regarding neonatal outcome were observed. Conclusions: Our study suggests that induction of labour in late and postterm pregnancies is associated with a significantly higher cesarean section rate. Other maternal and fetal parameters were not influenced by induction of labour.
