Study design
Purpose of the study
Treatment
Allocation to intervention
Randomised controlled trial
Procedure for enrolling a subject and allocating the treatment (allocation concealment procedures)
Referral from a clinician deciding that induction is necessary during the process of antenatal care. A research officer checks eligibility and initiates randomisation from an off site randomisation centre. Randomisation is not blinded by the nature of the intervention
Methods used to generate the sequence in which subjects will be randomised (sequence generation)
Randomisation blocks stratified to site of intervention and parity
Masking / blinding
Open (masking not used)
Who is / are masked / blinded?

Summary
Brief summary
Hospital versus home based induction of labour
This study aims to find out whether or not it is good practice to permit pregnant women to go home to rest after they have had induction of labour started. The study is important because it will identify potential advantages and disadvantages to this approach, so that women can make properly informed choices about their care.
