Objective: To assess the factors responsible for failed induction of labour (IOL) in a Tertiary care hospital. Method: This is a cross sectional study on women admitted for labour induction in Sri Krishna Medical College and Hospital, Muzaffarpur, Bihar from August 2020 to July 2021. Induction was considered successful if the patient delivered vaginally and failed if it ended up in Caesarean Section. Result: Eighteen percent of our pregnant population who underwent induction of labour failed to deliver vaginally. About 25% of 328 nulliparous women had failed induction. With a Bishop score of <5 in 84.3%. In 28.2% with prolonged latent phase of more than 20 hours in Caesarean section had to be performed. Conclusion: Nulliparity, poor Bishop score and prolonged latent phase had strongest association with failed Induction of Labour. Macrosomia, gestation age, bad obstetric history and pre labour rupture of membranes were other significant risk factors for emergency caesarean sections in IOL.
