Does non-Hispanic black race increase the risk of severe morbidity and mortality in women with preeclampsia?
Non-Hispanic black women with preeclampsia are at significantly higher risk for severe maternal morbidity and mortality, including stroke and heart failure, compared to other racial groups.
Objective: The objective of this study was to assess how race is associated with adverse maternal outcomes in the setting of preeclampsia.Study design: This retrospective cohort study utilized the National (Nationwide) Inpatient Sample (NIS) from the Agency for Health care Research and Quality for the years 2012-2014. Women aged 15-54 with a diagnosis of preeclampsia were included. Race and ethnicity were categorized as non-Hispanic white, non-Hispanic black, Hispanic, Asian or Pacific Islander, Native American, other, and unknown. The overall risk for severe morbidity based on Centers for Disease Control and Prevention criteria was analyzed along with the risk for specific outcomes such as stroke, acute heart failure or pulmonary edema, eclampsia, and acute renal failure. The risk for severe morbidity was stratified by comorbid risk and compared by race. Log-linear regression models were created to assess risk for severe morbidity with risk ratios and associated 95% confidence intervals as measures of effect.Results: A total of 101,741 women with preeclampsia from 2012 to 2014 were included in this analysis. The risk for severe morbidity was significantly higher among non-Hispanic black women (9.8%) than non-Hispanic white, Hispanic, and all other women, respectively (6.1, 7.7, and 7.5%, respectively, p p p p p p Conclusion: Black women were at higher risk for severe morbidity and mortality associated with preeclampsia.
