Author(s): Jasmeet Kumari, Anam Munir, Maire Milner

Objective: The aim of this study is to determine the impact of indication for induction of labour on mode of delivery. Study design: A retrospective study.

Place and duration of study: Our Lady of Lourdes Hospital, Drogheda, RCSI group of hospitals, Ireland, from 1st January 2019 till 31st December 2019.

Methodology: In this retrospective cohort 409 case notes of primigravida whose labour was induced were selected. Indication for induction, Gestational age, parity, BMI and mode of delivery was taken into account.

Results: In 2019, 2908 patients delivered a baby over 500g in the unit. Among these 1011 (34.8%) were primipara and 1897(65.2%) were multipara. The caesarean section (CS) rate for the year was 34.3% and induction rate 32.3%.

Conclusion: Mode of delivery was affected by indication of induction which was highest among women induced for suspected macrosomia. CS is a major surgery with adverse risks to mother both in current and subsequent pregnancies. Maternal demographic factors like obesity (BMI >30), advanced birth weeks and, nulliparity are independent risk factors for CS risk. A planned caesarean deliveryshould be discussed with the woman in presence of secondary risk factors, to avoid the trauma and prolong hospitalization that can result from failed induction.
