Remote blood pressure telemonitoring in hypertensive pregnancies: Feasibility and preliminary outcomes from a...

We evaluated the feasibility and early outcomes of a prototype remote blood pressure (BP) monitoring pathway for hypertensive disorders of pregnancy (HDP) implemented in a multidisciplinary clinic. In a retrospective single-centre before-after cohort, 38 consecutive women were analysed: the first 19 enrolled in telemonitoring (Group A; January-December 2024) received a validated upper-arm BP monitor, standardized technique training, and home readings submitted via a secure digital platform reviewed by clinicians; the preceding 19 (Group B) received standard in-person surveillance. Median age was 34.5 years (IQR 31.0-37.75); 34.2% were primigravida. Group A required fewer in-person consultations (2.68 ± 1.53 vs 3.84 ± 1.68; 30% relative reduction; p = 0.02). Baseline office BP and 24-hour ABPM indices were similar between groups. Group A was older (36 vs 32 years; p = 0.049) and had higher maternal-fetal risk-factor burden (2 vs 1; p = 0.009). Any maternal-fetal event occurred in 68.4% vs 63.2% (p = 0.732), while preeclampsia was more frequent in Group A (36.8% vs 5.3%; p = 0.042). Telemonitoring enabled review of BP trajectories and prompted reassessment when needed. Limitations include small sample size, retrospective design, and case-mix confounding. Overall, remote BP monitoring appeared feasible and reduced routine visits without worse BP indices or overall event rates, supporting larger controlled prospective evaluations of clinical effectiveness and implementation.
