Largest COVID-19 Study of Hospitalized Patients in US Links Comorbidities to Acuity

At triage, about of third of all patients (1,734) presented with a fever, 986 had a high respiratory rate and 1,584 patients received supplemental oxygen. On average, patients were discharged after four days. The mortality rates were higher for male patients than female at every adult 10-year age interval.

The Northwell Health Covid-19 Research Consortium’s findings demonstrated that hypertension (57%), obesity (41%) and diabetes (34%) were the most common comorbidities in the COVID-19 patients studied. Patients with diabetes were more likely to have received invasive mechanical ventilation, received treatment in the intensive care unit (ICU) or developed acute kidney disease.

Of the 2,634 hospitalized patients for whom outcomes were known, 14% were treated in the ICU, 12% received invasive mechanical ventilation and 3% were treated with kidney replacement therapy. As of April 4, 2020, for patients requiring mechanical ventilation (n = 1151, 20.2%), 38 (3.3%) were discharged alive, 282 (24.5%) died, and 831 (72.2%) remained in hospital.

“Through our consortium, we will share our clinical and scientific insights as we evolve the ways to care for and treat COVID-19 patients,” said Karina W. Davidson, PhD, MASc, professor and senior vice president at the Feinstein Institutes.

“These observational studies and other randomized clinical trial results from the Feinstein Institutes will improve the care for others confronting COVID outbreaks,” added Kevin J. Tracey, MD, president and CEO of the Feinstein Institutes.
