Plain English Summary

Background and study aims
In 2012, 7% of live births in England and Wales were premature (born before 37 weeks). Babies born prematurely may need special care, are more likely to die and are more likely to have disabilities or develop health problems in adult life than those born at full term. In 40% of cases, the cause of premature birth is unknown. However, it is known that some women are more at risk. This includes, for example, those who have previously given birth early, have had a late miscarriage or women who have had surgery on their cervix. A study found that women who receive care from the same midwife or team of midwives during pregnancy, birth and after birth are 24% less likely to experience preterm birth. Screening women at risk of preterm birth in specialist obstetric clinics is now considered to be helpful, but these methods are rarely used and women who require specialist expertise often suffer from fragmented maternity care. A care pathway has been developed which combines continuity of midwife care with rapid referral to a specialist obstetric clinic throughout pregnancy through to the postpartum period for women who at high risk of preterm birth. The aim of this study to test whether this new model of care is feasible and improves experience and outcomes for mother and child.

Who can participate?
Pregnant women with a single pregnancy (24 weeks or less) who at risk of preterm birth

What does the study involve?
Participants are randomly allocated either to standard care or the preterm midwifery team. Participants allocated to standard care receive the same care as they would normally receive according to their local maternity services in line with usual practice. Participants allocated to the the preterm midwifery team are assigned a named midwife and a partner midwife who together with a small team of midwives provide continuity of care throughout pregnancy, birth and the postnatal period. The midwife works in partnership with the participants, assesses their needs, plans their care, refers them to other professionals if required, and ensures that they have access to maternity services needed. All participants are followed up through the hospital records and questionnaires. Some participants are invited to attend an interview during the postnatal period about their experience of the type of care received.

What are the possible benefits and risks of participating?
It cannot be promised that the study will directly benefit the participants, but it will help to develop a model of maternity care that may benefit women in the future. Taking part in the study is not expected to disadvantage participants in any way. However, completing the questionnaires and an interview may take up to one hour of their time.

Lewisham and Greenwich NHS Trust (UK)

Study acronymPOPPIE
Study hypothesisA model of continuity of midwifery care for women at risk of preterm birth is feasible, and improves pregnancy experience and outcomes.
Ethics approval(s)London - South East Research Ethics Committee, 07/03/2017, ref: 17/LO/0029
ConditionSpecialty: Reproductive health and childbirth, Primary sub-specialty: General Obstetrics/ Midwifery; UKCRC code/ Disease: Reproductive Health and Childbirth/ Complications of labour and delivery
InterventionThe allocation ratio of intervention to control will be 1:1. Randomisation will be managed via a secure web-based randomisation facility hosted by MedSciNet which will write the randomisation program and hold the allocation code.

POPPIE care
Women randomised to the intervention group will receive continuity of midwifery care, which aims to provide ante-, intra- and postnatal care mainly from one midwife or her/his practice partner (backed up by the team for out of hours care) in either community or hospital settings, to a defined group of women identified at increased risk of preterm birth. Midwife continuity of care is provided in a multi-disciplinary network of consultation and referral with other care providers. Some antenatal and/or intrapartum and/or postpartum care is provided in consultation with medical staff as appropriate. Within these models, midwives are, however, in partnership with the woman, the lead professional with responsibility for assessment of her needs, planning her care, referral to other professionals as appropriate, and for ensuring provision of maternity services. The POPPIE team will comprise 6 wte midwives, including the team leader.

Standard care
Women allocated to the control group will receive the current model of maternity care at the study site with access to expertise as required according to NICE and Trust antenatal care guidelines. Antenatal care is provided by antenatal staff (midwives and obstetricians). Staff in the Birth Units provide labour and birth care and midwives in the postnatal ward provide postnatal care. Women are also offered midwifery visits at home following discharge from hospital.
Intervention typeOther
