Respiratory failure & ventilation
Factors related to COVID‐19 mortality among three Swedish intensive care units—A retrospective study
Authors' conclusion
Age, disease severity, and nurse staffing, but not treatment or socioeconomic status, were independently associated with 90-day mortality among critically ill patients with AHRF due to COVID-19.

Main finding
As reported in the abstract
90-day mortality
- After multivariable adjustment, age, ARDS severity and number of nurses per ICU-bed independently predicted 90-day mortality
- Differences between units in disease severity, treatments, process-related and socioeconomic factors; these factors related to 90-day mortality
- Multivariable logistic regression
Observational data: associations, not effects.
