Background and study aims
High blood pressure in pregnancy is an increasingly common complication that increases the risk of adverse pregnancy outcomes including maternal and infant death, damage to the mother’s liver and kidneys, and premature birth. The impact of high blood pressure in pregnancy on women’s health and wellbeing in the postnatal period is not well understood, along with the extent to which current postnatal services are evidence-informed and if they are meeting women’s needs. This study aims to compare the postnatal health of, and the care provided to, women who had high blood pressure in pregnancy compared with women who had normal blood pressure in pregnancy.

Who can participate?
Women aged 18 or above who gave birth in any of the participating NHS foundation trusts

What does the study involve?
Eligible women are approached and provided with study information on the postnatal ward and those happy to participate are asked to complete a consent form and short (5 minute) questionnaire. Following this initial contact at about three months postnatal participating women are invited to complete a 15-minute questionnaire with questions on their physical health, mental health, their babies feeding habits and the postnatal care they received.

What are the possible benefits and risks of participating?
The study findings will be used to provide evidence on if, and how, postnatal health differs amongst women with more complex pregnancies, compared to lower risk pregnancies, and if care beyond birth is meeting these women’s needs, with the view of informing revisions to current postnatal services.

Scientific titlePostnatal health and care following hypertensive disorders in pregnancy: a prospective cohort study
Study acronymBPiPP
Study objectives1. Do women with hypertensive disorders in pregnancy experience greater postnatal physical and psychological morbidity compared to women with normal blood pressure in pregnancy?
2. Does the extent and characterisation of postnatal morbidity differ between women with hypertensive disorders in pregnancy and women with normal blood pressure in pregnancy?
3. Do women with hypertensive disorders in pregnancy receive additional postnatal care (contacts and content in line with relevant NICE guidance) compared to women with normal blood pressure in pregnancy?

Health condition(s) or problem(s) studiedHypertension during pregnancy
InterventionEligible women will be approached and provided with study information on the postnatal ward and those happy to participate will be asked to complete a consent form and short (5 minute) questionnaire. Following this initial contact at approximately 3 months postnatal participating women will be invited to complete a 15 minute questionnaire, with questions included on their: physical health, mental health, their babies feeding habits and the postnatal care they received. BPiPP study findings will be used to provide evidence on if, and how, postnatal health differs amongst women with more complex pregnancies, compared to lower risk pregnancies, and if care beyond birth is meeting these women’s needs, with the view of informing revisions to current postnatal services.
Intervention typeOther
Primary outcome measureCo-primary outcomes for research question 1:
1. Depressive symptoms, measured using the Edinburgh Postnatal Depression Score (EPDS) questionnaire (mean and threshold scores ≥13 - standard cut-off score recommended when screening for probable major depression), at 3 months postnatal
2. Health status, measured using the EuroQol Group five dimension (EQ-5D) questionnaire (mean score on the vertical visual analogue scale score), at 3 months postnatal

Primary outcomes for research question 2:
Presence and severity of morbidities measured from patient reported study survey responses at 3 months postnatal

Primary outcome for research question 3:
Women’s opinion of their postnatal care contacts and content and measures of NICE guidance adherence measured from patient reported study survey responses at 3 months postnatal
Secondary outcome measuresPatient reported study survey responses at 3 months postnatal will also capture:
1. Other physical and psychological morbidity outcomes (including EQ-5D level per domain)
2. Re-admission rates
3. Breastfeeding uptake and duration rates
4. Mean number of visits/contacts with NHS services
