Consent: Eligible women will be asked if they would like to participate. If they verbally agree to participate, they will be invited to attend the hospital prior to admission for planned birth. If they are still happy to participate, they will be asked to sign the trial consent form.
At most, we may ask women to attend the hospital twice for the trial; where possible, we will combine any visits needed for the trial with routine antenatal appointments to avoid extra appointments. However, combining the trial visit with routine visits may mean an overall extended visit.
Baseline data collection: Once consent is taken, information will be collected from the women’s medical records, including existing medical conditions, obstetric history and current pregnancy details. This information will be entered into the trial database by a research nurse/midwife. The online database will be managed and maintained by the University of Edinburgh.
