Postpartum remote blood pressure monitoring and risk of hypertensive-related readmission: systematic review and meta-analysis of randomized controlled trials

Journal article

Objectives

To assess the efficacy of remote blood pressure monitoring to prevent readmission due to complications of hypertensive disorders of pregnancy.

Methods

The search was conducted using MEDLINE, EMBASE, Web-of-Sciences, Scopus, ClinicalTrial.gov, OVID and Cochrane-Library as electronic databases from the inception of each database to November 2023. Selection criteria included randomized controlled trials of postpartum individuals randomized to remote blood pressure monitoring or telehealth strategies vs. routine-care. The primary outcome was postpartum readmission, defined as postpartum hospital admission after discharge. Secondary maternal outcomes included stroke, eclampsia, ICU-admission, maternal death, emergency department visit, ascertainment of a blood pressure measurement within 7-10 days after delivery, attendance of the 4-6-week postpartum visit. The summary measures were reported as relative risk (RR) or as mean difference (MD) with 95 % confidence intervals (CI).

Results

Four RCTs including 714 individuals randomized to either telematic reporting of blood pressure measurements (n=356, 49.8 %) or standard postpartum care (n=358, 50.1 %). There were no significant differences in the rate of hospital readmission due to hypertensive related causes (5.3 % vs. 11.8 %). However, emergency department visit rate differed significantly among the two groups (9.0 % vs. 4.4 %). With regards to postpartum follow up, blood pressure assessment at 10 days postpartum and 4-6-week postpartum visit attendance rate were similar. No included RCT provided data on maternal secondary outcome like pulmonary edema, stroke, maternal death, and ICU admission.

Conclusions

Remote blood pressure monitoring is not superior to standard care to prevent hypertensive related readmission and increases emergency department visits.
