Trial results for a study investigating remote blood pressure monitoring in postpartum women with Hypertension were posted on ClinicalTrials.gov on 2026-03-02. The study, which enrolled 1607 participants, found that remote monitoring significantly increased adherence to American College of Obstetricians and Gynecologists (ACOG) blood pressure monitoring guidelines, from 30.8% in standard of care to 78.6% with remote monitoring.
Background
Hypertension, or high blood pressure, can develop in women after delivery, even if they had not experienced it during pregnancy. Untreated or undiagnosed high blood pressure in the postpartum period can lead to serious medical complications, some of which can be life-threatening. Monitoring blood pressure after childbirth is crucial for early detection and management. Remote blood pressure monitoring has been suggested as a method to improve postpartum surveillance.
Trial design
This completed study, designated as Phase NA, enrolled 1607 participants to investigate the usefulness of remote blood pressure monitoring in postpartum women with Hypertension. The trial compared remote blood pressure monitoring (rBPM) for three weeks post-discharge with standard of care (SOC) to assess its impact on monitoring adherence and other outcomes.
Key results
The trial reported several key measurements:
- Proportion of Participants Monitoring Blood Pressure (BP) According to American College of Obstetricians and Gynecologists (ACOG) Guidelines:
- For the Standard of Care (SOC) group, the proportion was 0.308.
- For the Remote Blood Pressure Monitoring (rBPM) group, the proportion was 0.786.
- Median Number of Remote Blood Pressure (rBPM) Measurements Obtained Per Participant:
- In the Remote Blood Pressure Monitoring (rBPM) group, the median was 6 measurements.
- Median Total Cost of Health Care:
- For the Standard of Care (SOC) group, the median cost was 1040 US dollars.
- For the Remote Blood Pressure Monitoring (rBPM) group, the median cost was 1046 US dollars.
- Number of Participants Experiencing at Least One Day With a Severe Hypertension Event:
- In the Standard of Care (SOC) group, the number of participants was 22.
- In the Remote Blood Pressure Monitoring (rBPM) group, the number of participants was 27.
- Another measurement for the Standard of Care (SOC) group reported 4 participants.
- Another measurement for the Remote Blood Pressure Monitoring (rBPM) group reported 34 participants.
- A further measurement for the Standard of Care (SOC) group reported 35 participants.
- A further measurement for the Remote Blood Pressure Monitoring (rBPM) group reported 66 participants.
- Yet another measurement for the Standard of Care (SOC) group reported 10 participants.
What this means
The results indicate that remote blood pressure monitoring significantly increased the proportion of postpartum women adhering to ACOG blood pressure monitoring guidelines, from 30.8% in standard care to 78.6% with remote monitoring. Participants in the remote monitoring group took a median of 6 measurements. The median total healthcare costs were comparable between the two groups, with 1040 US dollars for standard of care and 1046 US dollars for remote monitoring. While remote monitoring improved adherence, the data also showed varying numbers of participants experiencing at least one day with a severe hypertension event across different measurements, with some instances showing higher numbers in the remote monitoring group (e.g., 66 vs 35, 34 vs 4, 27 vs 22), which could suggest improved detection of such events due to more frequent monitoring.
