At our institution patients were admitted to the COVID-ICU if they tested COVID positive and had high enough acuity to require ICU level care. In my experience working with COVID-19 patients in the ICU, almost 1/3 of the patients who were admitted to the ICU had a non-pulmonary based reason for being admitted (severe CHF exacerbations, acute renal failure, new onset heart block). Therefore based on this study they would have met criteria for having a severe COVID infection. However, many of these patients had no acute need for oxygen supplementation or pulmonary based interventions. That being said, I know that much of the discussion centered around ACE-2 is its expression within lung tissue. Although it remains unclear what the exact role ACE-2 may play both in COVID acquisition and severity, I'm curious if there was any discussion about creating more rigorous criterion for the category of ICU admission. Would it have been more beneficial to look specifically at patients admitted to the ICU for pulmonary related complications from COVID-19 rather than at ICU admissions as a whole to help delineate severity? Or perhaps analyzing patients admitted to the ICU specifically for COVID complications?
