Intervention/exposure
Study type
Interventional
Description of intervention(s) / exposure
Women eligible for randomisation who screen high risk of caesarean section for slow progress in labour will be offered randomisation for two arms: induction of labour at 39 week's vs continuation of normal pregnancy care.
The intervention is induction of labour in the 39th week of pregnancy. The consent for induction will be undertaken by the research team (doctor or midwife) and the induction process will be undertaken as per local health policy guidelines by clinical midwives or doctors with cervical ripening using Prostoglandin E2 and/or cook's balloon catheter (if Bishop score <7) with appropriate external fetal monitoring followed by artificial rupture of membranes and syntocinon with appropriate fetal monitoring (as needed).
There are one to two slots per week allocated for this pilot which are seperate to the normal induction bookings as not to interfere with normal induction booking process. The day of labour induction in the 39th week will be decided based on both participant preference as well as labour ward acuity (including other booked indicated induction, staffing allowances, preferred weekday slots and emergencies) to ensure that patient safety is not compromised.
Given this is a pilot study to assess feasibility, intervention fidelity (ie induction in the 39th week) will be assessed both qualitatively with a patient satisfaction questionnaire and quantitatively through audit of medical records.

Comparator / control treatment
Active Control: continuation of normal pregnancy care.
Normal pregnancy care encompasses routine ultrasound review and weekly review of patients. If complications of pregnancy develop, patients will undergo appropriate review, investigation and management by clinicians (midwives and doctors who are not nominated research staff). Review may lead to the possibility of medically indicated induction of labour or emergency caesarean section prior to onset of spontaneous labour. After delivery, medical records will be audited.

Study design
Purpose of the study
Prevention
Allocation to intervention
Randomised controlled trial
Procedure for enrolling a subject and allocating the treatment (allocation concealment procedures)
Allocation involves contacting the holder of the allocation schedule who is "off-site"
Methods used to generate the sequence in which subjects will be randomised (sequence generation)
Randomisation will be performed as block randomisation with a 1:1 allocation.
Masking / blinding

Statistical methods / analysis
Analysis will be by intention to treat (according to treatment allocation), including withdrawals and losses to follow up.
The results will be reported according to CONSORT guidelines.
Demographics and other potential confounders will be compared by treatment allocation in a univariate analysis. Categorical outcome measures will be compared by proportions (chi-squared test), means for normally distributed data (t-test), or rank order for non-normally distributed data (Wilcoxon rank sum test).
