Comparing two methods of starting an induction of labour in pregnant women (balloon at home versus hormone gel in hospital) to assess chance of vaginal birth

The induction of labour rate in New Zealand is high. Mechanical methods of induction in hospital are safe and effective. However, most women in New Zealand have induction using pharmacological methods. Trials are needed to determine the safety and effectiveness of outpatient induction with balloon catheter. Outpatient balloon induction has the potential to give women more choice and improve satisfaction, and to save on health care costs, while maintaining safe outcomes for mothers and their babies.

This trial aims to compare two management protocols for initial management of induction of labour. To demonstrate safety, clinical effectiveness and cost effectiveness for mothers and babies who are allowed to go home after commencing a balloon induction, versus remaining in hospital after commencing a prostaglandin induction.

If outpatient balloon induction is found to be as safe and effective as inpatient prostaglandin induction in low-risk women, then district health boards can incorporate this protocol into their clinical guidelines. Moreover, this evidence-based recommendation can be added to the Auckland Consensus Guideline (2014), enabling consistency of practice across the country.
