(234) Blood Pressure Machines and Attendance of Follow-up Visit within 10 Days of Delivery

Thursday, January 30, 2025
10:30 AM – 12:30 PM  
Objective: Hypertensive disorders of pregnancy (HDP) contribute to maternal morbidity and mortality in the postpartum period and disproportionately affects Black, Indigenous and people of color (BIPOC). ACOG recommends that women with a HDP have a blood pressure evaluation within 10 days of delivery. This study assessed whether access to a blood pressure machine (BPM) with direction to self-monitored blood pressure (SMPB) increased adherence to this recommendation at our tertiary care center.

Study Design: This was a retrospective chart review of patients with HDP who delivered between July 1, 2020 and June 30, 2021. BPM were provided to HDP patients without one, with recommendation for SMBP. The primary outcome was attendance of follow-up visit within 10 days of delivery.  Fisher’s exact and Mann-Whitney U tests, and multivariable logistic regression were used. Self-identified race and ethnicity, maternal age, delivery mode, severe features, postpartum day of discharge, prescription for anti-hypertensive medications at discharge, and ownership of a BPM were included in the model.

Results: 381 patients met inclusion criteria. 211(55.4%) identified as non-Hispanic Black and 146 (38.3%) as Hispanic; 105(27.6%) had severe HDP. 110(28.9%) patients were discharged with anti-hypertensive medication. 270(70.9%) patients had a BPM; 38(14.1%) owned and 232 (85.9%) were provided a BPM. 194 (50.9%) patients attended 10-day follow-up visit. 108(57.8%) patients with a BPM and 86(44.3%) patients without a BPM (p=0.01) attended follow-up visit. Attendance of 10-day visit was predicted by ownership of a BPM (OR 1.8, 95% CI 1.1-3.0), cesarean delivery (OR 3.2, 95% CI 1.8-5.6), and Hispanic identification (OR 1.7, 95% CI 1.1-2.7).

Conclusion: In patients with HDP, BPM ownership predicted returning for a visit within 10 days. Provision of BPM likely connected patients more effectively to their postpartum care. Universal BPM provision with SMBP guidance could improve postpartum follow and reduce hypertension-related morbidity and mortality in this vulnerable population of historically minoritized patients.
