The Journal of the American Medical Association published a peer-reviewed article on the clinical characteristics of 138 patients with COVID-19. 26.1% of patients were admitted to the intensive care unit (ICU) due to complications, and 15.9% of patients had respiratory failure from ARDS (acute respiratory distress syndrome), even though "most patients received antiviral therapy (oseltamivir, 124 [89.9%]), and many received antibacterial therapy (moxifloxacin, 89 [64.4%]; ceftriaxone, 34 [24.6%]; azithromycin, 25 [18.1%]) and glucocorticoid therapy (62 [44.9%])." At the end of the study period, on February 3rd, 61.6% of patients were still hospitalized.
Median age was 56 years, and 54.3% were men. 29% of patients were health-care workers. Mean time from first symptoms to respiratory failure from ARDS was 8 days.
"Of the 36 cases in the ICU, 4 (11.1%) received high-flow oxygen therapy, 15 (41.7%) received noninvasive ventilation, and 17 (47.2%) received invasive ventilation (4 were switched to extracorporeal membrane oxygenation)."
