Intervention/exposure
Study type
Interventional
Description of intervention(s) / exposure
A customised fetal growth chart that is individualised for the specific pregnancy using maternal and pregnancy characteristics and can be used with routine measurements of fundal height. The intervention will be used at each antenatal visit after 24 weeks gestation by entering the fundal height measurement into the system, which will then plot it on the chart, with all previous measurements. The charts will be used up until delivery of the baby.

Comparator / control treatment
A non-customised fetal growth chart that can be used with routine measurements of fundal height. The intervention will be used at each antenatal visit after 24 weeks gestation by entering the fundal height measurement into the system, which will then plot it on the chart, with all previous measurements. The charts will be used up until delivery of the baby.

Prevention
Allocation to intervention
Randomised controlled trial
Procedure for enrolling a subject and allocating the treatment (allocation concealment procedures)
To generate the growth chart to be used, the required parameters for the customisation process will be entered during the booking interview with the midwife. Once the first doctor’s visit has occurred, and the model of care (i.e. to exclude women accessing GP shared care) and plurality (i.e. to exclude multiple pregnancies) have been entered, the chart will be produced and saved in the electronic obstetric clinical system. The randomisation schedule will be saved into this same system and the chart (either standard or customised) will be generated based on the next allocation in the randomisation sequence.
Methods used to generate the sequence in which subjects will be randomised (sequence generation)
A computer generated randomisation schedule will be generated prior to study commencement that will be used to allocate patients to either the standard chart or customised chart. Variable block randomisation will be used, as well as stratification by pregnancy risk (low risk and high risk). Women who are allocated to the obstetric model of care at the first doctor’s visit will be classified as high risk; all others will be low risk.
