Systematic treatment and management of postpartum hypertension using remote patient monitoring.

OBJECTIVE

To describe postpartum visit attendance and postpartum blood pressure control among patients enrolled in a remote patient monitoring program and compare these outcomes by race.

STUDY DESIGN

A prospective cohort study of postpartum patients with a diagnosis of hypertensive disorders of pregnancy at the University of Chicago between October 2021 and April 2022. All patients received remote patient monitoring as routine care but consented separately for the use of their data. Data were obtained from the electronic medical record for up to six weeks postpartum.

MAIN OUTCOME MEASURES

The primary outcome was attendance at the first postpartum blood pressure check visit. Secondary outcomes included postpartum blood pressure control, readmissions, and remote patient monitoring response rates. Outcomes were compared by patient-reported race.

RESULTS

545 patients were enrolled in the remote patient monitoring program, of which 306 consented to data collection. 64.7% of patients identified as Black/African American. Attendance for first postpartum blood pressure check was high (overall 84.0%, Black 81.3% and non-Black 88.9%, p = 0.08). The rate of Stage 2 hypertension at six weeks was higher among Black patients than non-Black patients (22.4% vs 2.2%, p < 0.0001). Engagement with remote patient monitoring decreased over the 6-week period, with more attrition among Black patients.

CONCLUSION

There was a high follow-up rate across all patients regardless of race and a decrease in hypertension over the six-week period. However, rates of hypertension were higher, and engagement with the program lower in Black patients, suggesting further work is needed to address this gap.
