ACOG Green Journal: Postpartum Home Blood Pressure Monitoring

Postpartum Home Blood Pressure Monitoring


To assess the effectiveness of postpartum home blood pressure (BP) monitoring compared with clinic-based follow-up and the comparative effectiveness of alternative home BP–monitoring regimens.


Search of Medline, Cochrane, EMBASE, CINAHL, and from inception to December 1, 2022, searching for home BP monitoring in postpartum individuals.


We included randomized controlled trials (RCTs), nonrandomized comparative studies, and single-arm studies that evaluated the effects of postpartum home BP monitoring (up to 1 year), with or without telemonitoring, on postpartum maternal and infant outcomes, health care utilization, and harm outcomes. After double screening, we extracted demographics and outcomes to SRDR+.


Thirteen studies (three RCTs, two nonrandomized comparative studies, and eight single-arm studies) met eligibility criteria. All comparative studies enrolled participants with a diagnosis of hypertensive disorders of pregnancy. One RCT compared home BP monitoring with bidirectional text messaging with scheduled clinic-based BP visits, finding an increased likelihood that at least one BP measurement was ascertained during the first 10 days postpartum for participants in the home BP–monitoring arm (relative risk 2.11, 95% CI 1.68–2.65). One nonrandomized comparative study reported a similar effect (adjusted relative risk [aRR] 1.59, 95% CI 1.36–1.77). Home BP monitoring was not associated with the rate of BP treatment initiation (aRR 1.03, 95% CI 0.74–1.44) but was associated with reduced unplanned hypertension-related hospital admissions (aRR 0.12, 95% CI 0.01–0.96). Most patients (83.3–87.0%) were satisfied with management related to home BP monitoring. Home BP monitoring, compared with office-based follow-up, was associated with reduced racial disparities in BP ascertainment by approximately 50%.


Home BP monitoring likely improves ascertainment of BP, which is necessary for early recognition of hypertension in postpartum individuals, and may compensate for racial disparities in office-based follow-up. There is insufficient evidence to conclude that home BP monitoring reduces severe maternal morbidity or mortality or reduces racial disparities in clinical outcomes.
