Background Induction of labour (IOL) refers to techniques for stimulating uterine contractions to accomplish delivery prior to the onset of spontaneous labour1,2. IOL is associated with hyper-stimulation, foetal distress, uterine rupture, haemorrhage and amniotic fluid embolism.3–5 It is widely debated that IOL has no effect on increasing rates of operative delivery.6,7 However much of this data is based on using contentious control groups. In a climate of promoting normal birth to avoid maternal and foetal risks the importance of women being fully informed is paramount.
Objectives To assess whether the obstetric risk of women affects the outcomes of IOL.
Methods Review of outcomes in 2012 at Maidstone and Tunbridge Wells Hospitals (MTW) of labouring women. They were categorised into 10 groups depending on their obstetric risk (parity, rupture of membranes, presentation and gestation). Subsequently each group was analysed to find their obstetric outcomes and mode of delivery.
Results In 2012 there were 1746 Primips and 2007 Multips. The effect of IOL significantly increased the rates of operative delivery in both groups.
Conclusions It is important to compare women against their cohort controls. IOL increased risks and operative delivery in many groups at MTW Hospitals. The results were used to increase awareness at our unit by providing patient information leaflets aiding women to make an informed decision.
