Relationship Between a State-Directed Lockdown on Non-COVID-19-related ICU Admissions and Mortality in a Multicenter Colorado Healthcare System.

For non-COVID-19-related ICU admissions, mortality rate was similar before, during, and after Colorado's month long lockdown after confounder adjustment, including typical ICU admission flags. Primary admission diagnoses shifted throughout the predefined study periods with more admissions for severe critical diagnoses (i.e., ARF, sepsis, AWS) occurring during the mandated lockdown and nonmandated lockdown periods compared with the prepandemic and between surge period. This would suggest that the perceived increase in mortality during the lockdown for non-COVID-19 ICU admissions may be related to a shift inpatient demographics.
