Conditions

Monitoring of hypertension in women following hypertensive pregnancy Circulatory System

Interventions

Women recruited to the study will be randomly assigned to one of two groups: either monitoring their own blood pressure and using this to manage their blood pressure medication, or receiving the stand

Design outcomes

Primary

MeasureTime frame
Current primary outcome measures as of 22/10/2025: Mean daytime ambulatory diastolic blood pressure measured using an ambulatory blood pressure monitor at 26-39 weeks. _____ Previous primary outcome measures: Mean daytime ambulatory diastolic blood pressure measured using an ambulatory blood pressure monitor at 26 weeks.

Secondary

MeasureTime frame
Current secondary outcome measures as of 22/10/2025: 1. Mean daytime ambulatory systolic blood pressure measured using an ambulatory blood pressure monitor at 26-39 weeks 2. Mean 24-hour and nocturnal ambulatory blood pressure measured using an ambulatory blood pressure monitor at 26-39 weeks 3. Systolic and diastolic blood pressure at follow-up (mean of 2nd/3rd readings and mean of 2nd – 6th readings) measured in clinic or at home at baseline, 6 weeks, 12 weeks, 26-39 weeks and 48-60 weeks 4. Maternal health-related quality of life measured using EQ-5D-5L health questionnaire results at baseline, 6 weeks, 12 weeks, 26-39 weeks and 48-60 weeks 5. Anxiety associated with self-management of BP measured using the short-form anxiety inventory questionnaire at baseline, 12 weeks and 48-60 weeks 6. Medication adherence measured by the presence of urinary antihypertensive metabolites at 6 weeks and the Medication Adherence Rating Scale (MARS) at baseline and 6 weeks 7. Postnatal readmissions measured using all-cause admissions, pregnancy hypertension admissions and cardiovascular events at records review 8. Healthcare resource use and cost analysis of key cost drivers between study arms measured using participant resource use data collection at baseline, 12 weeks, 26-39 weeks and 48-60 weeks 9. Cost-consequence analysis presenting costs and key outcomes in a disaggregated manner measured over the trial period 10. Long-term modelled cost-utility analysis using quality-adjusted life years (QALYs) measured using Modelled lifetime horizon and Sensitivity analysis to judge time to benefit/harm 11. Qualitative process evaluation measured using in-depth semi-structured interviews over the trial period _____ Previous secondary outcome measures: 1. Mean daytime ambulatory systolic blood pressure measured using an ambulatory blood pressure monitor at 26 weeks 2. Mean 24-hour and nocturnal ambulatory blood pressure measured using an ambulatory blood pressure monitor at 26 weeks
