Objective:
Chronic hypertension (cHTN) in pregnancy is associated with adverse maternal and neonatal outcomes and necessitates specific management. Early detection and treatment of cHTN provides the opportunity to protect cardiovascular health during and after pregnancy. A distributed care network implemented a remote blood pressure monitoring (RBPM) intervention into routine prenatal care starting at the first visit for all patients at one of its urban obstetrical sites. We compared new diagnoses of cHTN among RBPM users at the intervention site to patients receiving usual care.

Study Design:
This is a retrospective cohort study using data from patients enrolled versus not enrolled in the RBPM intervention between 01/2020 and 09/2023. The primary outcome was new diagnosis of cHTN within the first 20 weeks of prenatal care. Age at delivery, race, ethnicity, insurance type, prior diabetes diagnosis, prior myocardial infarction, tobacco use during pregnancy, and BMI were covariates. A logistic regression model was fit to model the association between cHTN diagnosis and covariates. Average predicted probabilities of cHTN with 95% confidence intervals were displayed, and a significance level of 0.05 was used for all analyses.

Results:
7,866 patients were included in this study, with n=670 in the intervention group and n=7,196 in the comparison group. Patients in the intervention group were 2.24 times more likely to have a diagnosis of cHTN compared to those receiving usual care after adjusting for all covariates (p< 0.001). The predicted probability of a diagnosis of cHTN in the intervention group was 3.26% [2.29%, 4.63%] compared to 1.48% [1.20%, 1.82%] in the usual care group.

Conclusion:
Patients enrolled in the prenatal RBPM intervention group had significantly more diagnoses of CHTN in the first 20 weeks of pregnancy after adjusting for demographic variables and comorbidities.
