Discrimination by parity is a prerequisite for assessing induction of labour outcome – cross-sectional study
Abstract Background: To demonstrate that studies on induction of labour should be analyzed by parity as there is a significant difference in the labour outcome among induced nulliparous and multiparous women Methods: Obstetric outcome, specifically caesarean section rates, among induced term nulliparous and multiparous women without a previous caesarean section were analyzed in this cross-sectional study [BD1] using the Robson 10 group classification2 for the year 2016.Results: In the total number of 8851 women delivered in 2016[BD2] , the caesarean section rates among nulliparous women in spontaneous and induced labour, Robson groups 1 and 2A, were 7.8% (151/1925) and 32.6% (437/1339) respectively and among multiparous (excluding those women with a previous caesarean section), Robson group 3 and 4A were 1%(24/2389) and 4.4% (44/1005), respectively. Pre labour caesarean rates for nulliparous and multiparous women, Robson groups 2B and 4B2 were 3.9% (133/3397) and 2.8% (100/3494), of the respective single cephalic cohort at term.Conclusion: The data suggests that studies on induction of labour should be analyzed by parity as there is a significant difference between nulliparous and multiparous women.
