- A 1% increase in non-ICU bed utilization (130 beds on average) resulted in a 17.84 increase in COVID-19 mortality.
“ICU and non-ICU bed use was significantly associated with an increase in overall COVID-19 mortality over the next 7 days, as a percentage of the state’s bed capacity,” Washington University Faculty of Economics and CHOICE Institute chief. “The association strength of using ICU beds was higher than using non-ICU beds.”
