Mildly elevated blood pressure (BP) during and after delivery significantly increases the risk of postpartum hypertension readmission. Monitoring BP closely is crucial for identifying individuals at higher risk.
Area of Science:
- Obstetrics and Gynecology
- Cardiovascular Health in Pregnancy
- Public Health
Background:
- Postpartum readmission for hypertension is a significant concern, impacting maternal health outcomes.
- Understanding the relationship between peripartum blood pressure (BP) and readmission risk is essential for effective management.
Purpose of the Study:
- To evaluate the association between peripartum blood pressure (BP) changes and the risk of postpartum readmission for hypertension.
Main Methods:
- A retrospective cohort study analyzed 17,587 deliveries in Louisiana between January 1, 2017, and March 1, 2020.
- Patients were categorized based on BP levels at admission for delivery and 36 hours postpartum.
- Logistic regression identified risk factors for readmission within 30 days for hypertension.
Main Results:
- The study identified 329 cases (1.9%) of postpartum hypertension readmission.
- Elevated admission BP (aOR 2.26) and 36-hour postpartum BP (aOR 2.36) were strong predictors.
- Preeclampsia, Black race, anemia, and increased maternal age also significantly elevated readmission odds.
Conclusions:
- Even mildly elevated blood pressure (BP) during delivery admission and persisting postpartum substantially increases the risk of readmission for hypertension.
- These findings underscore the importance of vigilant BP monitoring in the peripartum period.

Special considerations while measuring blood pressure
Monitoring Both Arms:
Monitoring BP in both arms during the initial assessment is advisable, as the systolic value may differ by five to ten mm Hg between arms. For subsequent BP assessments, use the arm with the higher reading.
