Introduction: Vasopressor use has been associated with higher mortality rates in patients with COVID-19, the association between the maximum number of concurrent vasopressors with mortality has not yet been studied. Methods: A retrospective cohort study was conducted on patients admitted with COVID-19 to the intensive care unit (ICU) at Rush University System for Health in Illinois between March and October 2020. Multivariable logistic regression, adjusted for age, BMI, history of CAD and diabetes, was used to determine if an increasing number of vasopressors is associated with higher 60-day mortality. Results: A total of 637 patients met the inclusion criteria. Composite 60-day mortality was 28.6%. Of the 637 patients who met inclusion criteria, 338 (53.1%) required the support of at least one vasopressor. When compared to patients with no vasopressor requirement, those who required 1 (adjusted OR [aOR] 3.27, p Conclusion: In this cohort, each additional vasopressor added was associated with escalating 60-day mortality. Identifying these high-risk patients can help determine prognostic outcomes and guide decision-making. .

Introduction: The novel coronavirus disease 2019 (COVID-19) pandemic has affected millions of people worldwide. Higher COVID-19 mortality in men compared to women seen in many countries is not yet explained. We analyzed sex differences in COVID-19 outcomes in a large Illinois-based cohort. Methods: This is a multicenter retrospective cohort study of confirmed COVID-19 infections from March 1–June 3, 2020 in Rush University System. We compared men and women with COVID-19 infection for the rates of hospitalization, intensive care unit (ICU) admission, vasopressor use, endotracheal intubation, and death. A multivariable model correcting for age, race, and sum of comorbidities (obesity, hypertension, diabetes, coronary artery disease, heart failure, end-stage renal disease, asthma, chronic obstructive pulmonary disease, active smoking) was used to determine independent association with outcomes. Results: Of the 8,086 patients who tested positive, 4,267 (53%) were females, while 3,819 (47%) were males. Males had a higher rate of hospitalization (19% vs. 14%; p Conclusions: There were more women who tested positive for COVID-19 disease. Male sex was independently associated with higher rates of death, hospitalization, ICU admissions, need for vasopressors or endotracheal intubation, after correction for important covariates. The interplay of biological and and behavioral factors is likely responsible for the worse outcomes observed in men with COVID-19 infection. Further investigations into the pathophysiology of sex differences in COVID-19 outcomes responses are needed.
