Abstract only Introduction: Previous analyses on sex differences in case-fatality rates at population-level data had limited adjustment for key patient clinical characteristics thought to be associated with COVID-19 outcomes. Hypothesis: We aimed to estimate the risk of specific organ dysfunctions and mortality in women and men. Methods: This retrospective cross-sectional study included 17 hospitals within 5 European countries participating in the International Survey of Acute Coronavirus Syndromes (ISACS) COVID-19 (NCT05188612). Participants were individuals hospitalized with positive SARS-CoV-2 from March 2020 to February 2022. Risk-adjusted ratios (RR) of in-hospital mortality, acute respiratory failure (ARF), acute heart failure (AHF), and acute kidney injury (AKI) were calculated for women versus men. Estimates were evaluated by inverse probability of weighting and logistic regression models Results: The overall care cohort included 4,499 patients with COVID-19 associated hospitalizations. Of these, 1,524 (33.9%) were admitted to ICU, and 1,117 (24.8%) died during hospitalization. Compared with men, women were less likely to be admitted to ICU (RR: 0.80; 95%CI: 0.71-0.91). In general wards and ICU cohorts, the adjusted women-to-men RRs for in-hospital mortality were of 1.13 (95%CI: 0.90-1.42) and 0.86 (95%CI: 0.70-1.05; p interaction =0.04). Development of AHF, AKI, and ARF was associated with increased mortality risk (OR: 2.27; 95%CI; 1.73-2.98, OR: 3.85; 95%CI: 3.21-4.63 and OR: 3.95; 95%CI: 3.04-5.14, respectively). The adjusted RRs for AKI and ARF were comparable among women and men regardless of intensity of care. By contrast, female sex was associated with higher odds for AHF in general wards, but not in ICU (RRs: 1.25;9 5%CI: 0.94-1.67 versus 0.83; 95%CI: 0.59-1.16, p interaction =0.04). Conclusions: Women in general wards were at increased risk of AHF and in-hospital mortality for COVID-19 compared with men. For patients receiving ICU care, fatal complications including AHF and mortality appeared to be independent of sex. Equitable access to COVID-19 ICU care is needed to minimize the unfavourable outcome of women presenting with COVID-19 related complications.
