Research summary
More than 80% of women who are at high risk of developing high blood pressure problems, do not go on to develop pre-eclampsia, but are asked to frequently come into hospital for a review. Using the pre-existing home monitoring systems developed at St George's hospital in the HaMPtoN study we propose to develop this further to include an USS assessment of fetal wellbeing in the home setting.
The existing home monitoring protocol (standard of care) utilises the HaMPtoN app. Women are supplied with blood pressure monitors, urine dip sticks, and access to the HaMPtoN App which can be downloaded on any smart phone and are trained to use these. Patients on this care pathway measure their blood pressure twice-a-day, urine every 3-days, and monitor their own symptoms. Patients monitored on the home monitoring protocol are still seen in hospital every 1-2 weeks depending on individual needs.
The intervention will include standard of care described above, plus a bi-weekly home ultrasound scan. Women will receive dedicated training by one of the research team in how to use the device and how to connect to a teleconsultation. The handheld scan will be performed via the Pulsenmore clinican dashboard and will involve both sweeps and clinician guided scans.
The main aims are to assess home monitoring vs home monitoring with an at home ultrasound scan, assess the acceptability of home monitoring to patients and clinicians, perform a cost analysis of both systems, assess uptake amongst deprived communities vs routine care, and finally develop a predictive model using the data collected to assess for patients at higher risk of developing adverse pregnancy outcomes.
It is also important to assess healthcare professionals’ perspectives on home monitoring in pregnancy as a change in a care pathway will require buy-in from those who run the pathway.
