Abstract

Background: Maternal, neonatal and child health outcomes are worse in families from black and ethnic minority
groups and disadvantaged backgrounds. There is little evidence on whether lay support improves maternal and
infant outcomes among women with complex social needs within a disadvantaged multi-ethnic population in the
United Kingdom (UK).
Method/Design: The aim of this study is to evaluate a lay Pregnancy Outreach Worker (POW) service for
nulliparous women identified as having social risk within a maternity service that is systematically assessing social
risks alongside the usual obstetric and medical risks. The study design is a randomised controlled trial (RCT) in
nulliparous women assessed as having social risk comparing standard maternity care with the addition of referral
to the POW support service. The POWs work alongside community midwifery teams and offer individualised support to women to encourage engagement with services (health and social care) from randomisation (before 28 weeks gestation) until 6 weeks after birth. The primary outcomes have been chosen on the basis that they are linked to maternal and infant health. The two primary outcomes are engagement with antenatal care, assessed by the number of antenatal visits; and maternal depression, assessed using the Edinburgh Postnatal Depression Scale at 8-12 weeks after birth. Secondary outcomes include maternal and neonatal morbidity and mortality, routine child health assessments, including
immunisation uptake and breastfeeding at 6 weeks. Other psychological outcomes (self efficacy) and mother-to-
infant bonding will also be collected using validated tools.
A sample size of 1316 will provide 90% power (at the 5% significance level) to detect increased engagement with
antenatal services of 1.5 visits and a reduction of 1.5 in the average EPDS score for women with two or more
social risk factors, with power in excess of this for women with any social risk factor. Analysis will be by intention
to treat. Qualitative research will explore the POWs daily work in context. This will complement the findings of the RCT through a triangulation of quantitative and qualitative data on the process of the intervention, and identify other contextual factors that affect the implementation of the intervention.
Discussion: The trial will provide high quality evidence as to whether or not lay support (POW) offered to women
identified with social risk factors improves engagement with maternity services and reduces numbers of women
with depression.
