Planned study period: January 2024 – July 2026

Background and study aims

To develop and test the clinical and cost-effectiveness of an intervention to support self-management of antihypertensive medication following a hypertensive pregnancy. The intervention aims to improve long-term BP control and therefore reduce adverse cardiovascular outcomes and the associated costs to the NHS.

Who can participate?

Women in the postnatal period, requiring antihypertensive treatment

What does the study involve?

The intervention involves BP self-monitoring using a validated blood pressure monitor and self-titration of antihypertensive therapy guided by digital intervention, overseen by a supervising clinician.

What are the possible risks and benefits of participating?

During the trial, participants will continue to receive usual care regardless of randomisation group. As such we anticipate that the potential risks are low. Particular issues include a participant obtaining an excessively high or low BP reading in the self-monitoring and the possibility of increased anxiety due to the study.

We aim to minimise any potential risks due to poor blood pressure control by ensuring women have clear advice regarding when to seek urgent medical help.

Potential benefits for individuals taking part include better information about their BP and possible better control of blood pressure.
