Abstract
Objective: To analyze the association between pre-existing conditions, death, and length of hospital stay among postpartum women with COVID-19-associated severe acute respiratory infection (SARI). Methods: A retrospective, multicenter study was conducted using 1,526 eligible records of postpartum women with a final classification of COVID-19-associated SARI reported in SIVEP-Gripe between 2020 and 2021. Results: Pre-existing cardiovascular disease was associated with higher odds of death, even after statistical adjustment (OR=2.60; 95%CI 1.79–3.78; p<0.001). Although women with cardiovascular disease had longer hospital stays in the unadjusted analysis, this association did not persist in the quantile regression model. The need for ventilatory support and the use of medications during hospitalization were associated with longer hospital stays. Conclusion: Pre-existing cardiovascular disease was associated with higher odds of death but was not associated with length of hospital stay after adjustment. Indicators of clinical severity were associated with longer hospital stays.
