Racial differences in healthcare utilization among patients with suspected or diagnosed preeclampsia: A retrospective cohort study

Objectives: To analyze healthcare resource utilization and severe maternal morbidity (SMM) in Black and White patients with preeclampsia diagnosis versus signs/symptoms.Study design: This was a retrospective cohort study analyzing data from the IBM & REG; 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 measures: Healthcare 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).Results: Data 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 pa-tients (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%). Conclusions: Compared with White patients, Black patients had higher rates of antepartum emergency care and antepartum SMM.
