Public title
A pilot randomised controlled trial to determine the effect of a physiological (step) versus a standard action (slope) labour progress lines on the rate of spontaneous vaginal birth amongst low risk women in labour for the first time
Scientific title
For women in labour for the first time does a partograph with a graduated dystocia line compared to a standard sloping action line increase the likelihood of a spontaneous vaginal birth

Intervention/exposure
Study type
Interventional
Description of intervention(s) / exposure
The 'physiological' partogram is a visual tool that uses a graduated (stepped) line to indicate whether cervical dilatation, determined by vaginal assessment at regular intervals, is slower than a mean of 0.5cm per hour.
Intervention code [1] 289727 0
Diagnosis / Prognosis
Comparator / control treatment
The standard partogram is a visual tool that uses a sloping line to indicate whether cervical dilatation, determined by vaginal assessment at regular intervals, is slower than a mean of 1cm per hour.

Purpose of the study
Diagnosis
Allocation to intervention
Randomised controlled trial
Procedure for enrolling a subject and allocating the treatment (allocation concealment procedures)
Participants will be consented to the trial during the antenatal period. Upon assessment of active labour that attending midwife will obtain an opaque study envelope containing either an experimental or standard partogram labelled with a unique study code.
Methods used to generate the sequence in which subjects will be randomised (sequence generation)
Opaque envelopes containing partograms with pre printed stepped (intervention) or sloping (standard care) lines will be prepared by the Mater Research Institute using block randomisation
Masking / blinding
