Evaluation of Antepartum and Postpartum Remote Blood Pressure Monitoring in Low-Risk Pregnancy [9K

Abstract

INTRODUCTION: Hypertensive disorders in pregnancy are a leading cause of morbidity and mortality. This study examines the feasibility of an integrated technology platform to augment surveillance with remote blood pressure (BP) readings in low-risk pregnant women. METHODS: 2806 low-risk pregnant women in 57 offices were enrolled in an integrated technology platform with a mobile application and connected devices to remotely transmit BP readings (BabyscriptsTM (BRx) platform). Antepartum BP recordings were tabulated from 12-36 weeks gestation. Postpartum BP recordings were tabulated from 42-48 weeks gestation. All BP data was analyzed for mean systolic and diastolic BP and average interval between recordings. RESULTS: Antepartum monitoring of 2791 women showed a mean systolic BP of 107.3 (95% CI 102.1-112.5) and a mean diastolic BP of 68.9 (95% CI 61.7-76.1). A total of 38,443 antepartum BP readings were recorded. The average interval between recordings was 7.2 days. Postpartum monitoring of 186 women showed a mean systolic BP of 109.8 (95% CI 104.2-115.4) and a mean diastolic BP of 73.2 (95% CI 66.3-80.1). A total of 485 postpartum BP readings were recorded. The average interval between recordings was 5.1 days. CONCLUSION: Remote monitoring of BP in low-risk pregnant women resulted in frequent recordings during the antepartum and postpartum periods. Notably, the average frequency of postpartum recordings occurred at a shorter interval than typical clinical follow-up. This platform could offer more robust monitoring in low-risk pregnancies and could be extrapolated to high-risk pregnancies in the future.
