Objective:
Remote blood pressure monitoring (RBPM) is a key part of postpartum hypertensive disorders of pregnancy (HDP) care, but data comparing blood pressure (BP) control across antihypertensive regimens during participation remain limited. Here, we evaluate how standardized BP management in our 6-week RBPM program impacted postpartum BP trends and time in target range (TTR), stratified by discharge medication.

Study Design:
This is a retrospective cohort study of all individuals with HDP who enrolled in a six-week postpartum RBPM from November 2023-December 2024 at a single institution. This program uses a nurse-driven standardized protocol for antihypertensive medication initiation and titration to achieve a goal BP of ≤140/≤90 mmHg. Based on the standardized protocol utilized, we defined target range as a SBP 100-139 mmHg and DBP 60-89 mmHg. The primary outcome was BP trend and TTR throughout program participation stratified by antihypertensive medication at hospital discharge.

Results:
Of the 465 individuals in the cohort, 146 (31.4%) were discharged without antihypertensive medications, 40 (8.6%) on Labetalol only, 176 (37.8%) on Nifedipine only, and 93 (20%) on two or more medications. Ten used other antihypertensive medications. Mean BPs were < 140/90 mmHg for all groups for each program week. The steepest BP decline was observed within the first week followed by a plateau in both systolic and diastolic BP by week 4 of the program (Figure 1). The majority of participants were within target range throughout (TTR by group varied between 80.3-90.4%). Episodes of severe hypertension and hypotension were rare and not significantly different between groups (Figure 2).

Conclusion:
Postpartum RBPM programs have emerged as an important tool for postpartum care. Using an RN-driven standardized protocol for antihypertensive medication initiation and titration, our program achieves optimal BP control irrespective of medication regimen at discharge.
