Background/Objectives: In the postpartum period, approximately 12% of patients seek care in the emergency department (ED), with a higher representation of Black patients. Hypertension is a common reason for ED visits during this period, often leading to dangerously delayed diagnosis and treatment. Objective: This study aims to assess the time to diagnosis and treatment of hypertensive disorders in the postpartum period in the ED, focusing on potential disparities in care, to identify areas for quality improvement. Design: Retrospective cohort study. Setting: A multi-centered large medical institution in the metro Detroit area. Methods: Postpartum patients (day 2 through day 28) presenting to the ED from November 2015 to December 2022. Exposures: none. Main Outcome Measures: Primary analysis assessed the time elapsed between severe-range blood pressure readings (greater than/equal to 160 systolic and/or 110 diastolic) and the administration of antihypertensives. Secondary analyses assessed the presence of essential laboratory workups such as complete blood counts, complete metabolic panels, and urine protein and creatinine. Results: Among the 430 women who presented to the ED during the postpartum period with hypertension, 372 (86.5%) exhibited severe-range blood pressure (greater than/equal to 160 systolic and/or 110 diastolic). Patients presented on average on postpartum day 6. Of the patients with severe hypertension, only 72% received a complete blood count, 66% underwent evaluation of creatinine and liver profile, and 4% had a urine protein and creatinine test ordered. The average time from severe-range blood pressure reading to antihypertensive administration was 189 min for Black patients and 370 min for White patients. There were no statistically significant differences in the time of the first blood pressure reading, laboratory evaluation, or treatment of severe-range blood pressure between racial groups. Conclusions: This study identifies the most significant area for improvement in the timely administration of antihypertensive medication following severe-range blood pressure readings. Additional areas for improvement were observed in ordering essential laboratory tests to assess the severity of preeclampsia. The institution demonstrated delayed yet equitable care for White and Black patients, contrary to the existing literature indicating potential racial disparities. A targeted quality improvement plan has been implemented to improve the identified areas of concern to adhere to the ACOG’s treatment recommendations for hypertensive disorders of pregnancy. The impact on patient care will be reassessed at the 1-year mark.
