The objective of this study was to describe clinical characteristics of pregnant and postpartum women with severe COVID-19 in Brazil and to examine risk factors for mortality. The authors identified 124 maternal deaths, corresponding to a case fatality rate among COVID-19 Acute Respiratory Distress Syndrome (ARDS) cases in the obstetric population of 12.7%. At least one comorbidity was present in 48.4% of fatal cases compared to 24.9% in survival cases. Among women who died, 58.9% were admitted to ICU, 53.2% had invasive ventilation and 29.0% had no respiratory support. The multivariate logistic regression showed that the main risk factors for maternal death by COVID-19 were postpartum at onset of ARDS, obesity, diabetes, and cardiovascular disease, while white ethnicity had a protective effect.
