Study: Race Made No Difference in ICU Outcomes of COVID-19 Patients
Henry Ford Health System

In a study that looked at racial differences in outcomes of COVID-19 patients admitted to the intensive care unit, researchers at Henry Ford Hospital in Detroit found that patients of color had a lower 28-day mortality than white patients. Race, however, was not a factor in overall hospital mortality, length of stay in the ICU or in the rate of patients placed on mechanical ventilation, researchers said. The findings, published in Critical Care Medicine, are believed to be one of the first in the United States to study racial differences and outcomes specific to patients hospitalized in the ICU with COVID-19.

COVID-19 can spread from asymptomatic but infected people through small aerosol droplets in their exhaled breath. Most studies of the flow of exhaled air have focused on coughing or sneezing; however, speaking while near one another is also risky. In Physics of Fluids, scientists used smoke and laser light to study the flow of expelled breath near and around two people conversing in various relative postures commonly found in the service industry, such as in hair salons, medical exam rooms, or long-term care facilities.

Aerosol microdroplets do not appear to be extremely efficient at spreading the virus that leads to COVID-19.
