About

The goal of this observational study is to evaluate the feasibility and safety of a comprehensive home blood pressure telemonitoring (HBPT) program for pregnant people with hypertensive disorders of pregnancy (HDP).

Participants will receive training on the use of a home BP telemonitor with tele-transmission function for the remainder of their pregnancy and 6 weeks postpartum. Participating obstetric internal medicine (OBIM) clinicians will monitor the transmitted values and adjust anti-hypertensive medications based on the home BP readings.

Our primary goal is to describe the feasibility and safety of a comprehensive HBPT pilot program in British Columbia, Canada (BC).

Secondary research questions will address:

1. What is the end-user acceptability of a comprehensive HBPT pilot program in BC?

2. What are the effects of a comprehensive HBPT pilot program on factors such as:

3. Maternal and neonatal outcomes 2. Home blood pressure (BP) metrics 3. Process measures 4. Anti-hypertensive medications 5. Fidelity to interventions 6. Health Care utilization
