Black patients with COVID-19 are not more likely to receive invasive mechanical ventilation or to die during hospitalization, according to a study in the U.S. Centers for Disease Control and Prevention (CDC) Morbidity and Mortality Weekly Report.

Black Patients Overrepresented in Hospitalized COVID-19 Cohort

FRIDAY, May 1, 2020 (HealthDay News) -- In a cohort of hospitalized adults with COVID-19, black patients have a similar probability of receiving invasive mechanical ventilation or dying compared with nonblack patients, but they are disproportionately represented among hospitalized patients, according to a study published online April 29 in the U.S. Centers for Disease Control and Prevention (CDC) Morbidity and Mortality Weekly Report.

Jeremy A.W. Gold, M.D., from the CDC-COVID-19 Emergency Response, in Atlanta, and colleagues summarized medical record-abstracted data for 305 hospitalized adult patients with laboratory-confirmed COVID-19 admitted during March 2020 in Georgia. Of the patients, 61.6 percent were aged <65 years and 83.2 percent with known race/ethnicity were non-Hispanic black.

The researchers found that 26.2 percent of the patients did not have conditions thought to put them at elevated risk for severe disease, including age ≥65 years. A higher proportion of hospitalized patients were black than expected based on overall hospital admissions. Black patients were not more likely than nonblack patients to receive invasive mechanical ventilation or to die during hospitalization in an adjusted time-to-event analysis (hazard ratio, 0.63; 95 percent confidence interval, 0.35 to 1.13).

But a severely infected person who's coughing frequently can fill a poorly ventilated room with as many as 7.4 million copies of the coronavirus for every cubic meter of air, according to researchers Michael Riediker and Dai-Hua Tsai, from the Swiss Centre for Occupational and Environmental Health in Winterthur.
