Abstract
BACKGROUND: Hypertensive disorders of pregnancy (HDP) are a leading cause of maternal morbidity and mortality in the United States with an increased risk for hospital readmission and cardiovascular disease. The American College of Obstetricians and Gynecologists recommends that women with severe HDP follow-up within 72-hours post-discharge after childbirth. The purpose of this study is to evaluate if a postpartum hypertension (PPHTN) clinic improves follow-up and management. METHODS: Retrospective chart review of a referred cohort in a single-center, tertiary care hospital in Hartford, Connecticut. This study included women with severe HDP who were referred to the PPHTN clinic between March 2022 to February 2023. Primary outcomes were the percentage of patients seen within 72-hours postdischarge of hospitalization, percentage of patients achieving goal blood pressure (BP) (<130/80) at first and last follow-up visits, and hospital readmission rate. Secondary outcomes included the percentage of patients receiving HDP education materials, automatic BP cuff upon discharge from hospitalization, and antihypertensive medications prescribed postpartum. RESULTS: Our cohort had 157 women with a mean age of 32 years old (19-44), mean body mass index (BMI) 32 kg/m(2) (16-49), and were 39% White, 24% African American, and 33% Hispanic. Comorbidities included 41% nulliparity, 19% gestational diabetes, 23% HTN, 28% gestational HTN and 10% prior preeclampsia. Among the women seen in the clinic, 53% were observed within 72 hours, 28% achieved their goal BP at first visit, and 58% achieved their goal BP at subsequent visits. Hospital readmission occurred in 5% of women. Overall, 86% received HDP education and 89% had or were prescribed a BP cuff upon discharge. Lastly, 85% were discharged on antihypertensives and 60% required antihypertensive modification postpartum. CONCLUSION: Our initiative significantly improved the percentage of patients observed within 72 hours of discharge and facilitated longitudinal follow-up. Future analysis is needed to evaluate readmission rate reduction and the cost-effectiveness of the PPHTN clinic.
