Emergency room utilization was greater in Black patients with preeclampsia than White.
•Preeclampsia blood testing was less frequent in the Black than White cohort.
•Antenatal steroids use for preterm labor was less frequent in the Black than White cohort.
•Severe maternal morbidity rates were higher in Black patients with preeclampsia vs White.
•Black patients had more cardiovascular disease and corresponding resource use/tests.
AbstractObjectivesTo analyze healthcare resource utilization and severe maternal morbidity (SMM) in Black and White patients with preeclampsia diagnosis versus signs/symptoms.
Study designThis was a retrospective cohort study analyzing data from the IBM® Explorys Database between 7/31/2012–12/31/2020. Demographic, clinical, and laboratory data were extracted. Healthcare utilization and SMM were analyzed during the antepartum period (20 weeks of gestation until delivery) among Black and White patients with signs/symptoms of preeclampsia, with a diagnosis of preeclampsia, or neither (control).
Main outcome measuresHealthcare utilization and SMM in those with a preeclampsia diagnosis or signs/symptoms of preeclampsia only were compared with a control group (White patients with no preeclampsia diagnosis or signs/symptoms).
ResultsData from 38,190 Black and 248,568 White patients were analyzed. Patients with preeclampsia diagnosis or signs/symptoms were more likely to visit the emergency room compared to those without diagnosis or signs/symptoms. Black patients with signs/symptoms of preeclampsia had the highest elevated risk (odds ratio [OR] = 3.4), followed by Black patients with a preeclampsia diagnosis (OR = 3.2), White patients with signs/symptoms (OR = 2.2), and White patients with a preeclampsia diagnosis (OR = 1.8). More Black patients experienced SMM (SMM rate 6.1% [Black with preeclampsia diagnosis] and 2.6% [Black with signs/symptoms]) than White patients (5.0% [White with preeclampsia diagnosis] and 2.0% [White with signs/symptoms]). SMM rates were higher for Black preeclampsia patients with severe features than for White preeclampsia patients with severe features (8.9% vs 7.3%).
ConclusionsCompared with White patients, Black patients had higher rates of antepartum emergency care and antepartum SMM.
