ICU Patient Encounter Characteristics and Outcomes (2020-2021)
The table below showcases the characteristics and outcomes of ICU patient encounters across nine CLIF consortium sites. The cohort includes all adults (≥ 18 years) admitted to an ICU within 48 hours of hospitalization and staying at least 24 hours, from January 1, 2020, to December 31, 2021, at each site across the consortium. This represents a diverse cohort of over 111,000 ICU patient encounters and provides valuable insights into critical care practices across different institutions.
