In-Hospital Mortality Risk of Older Patients With COVID-19 Infection

I read the recent article published in this journal and written by Covino et al1 with great interest. The authors conducted a prospective study to evaluate the risk factors of mortality in adult COVID-19 patients aged ≥80 years. The adjusted hazard ratios (HRs) (95% CIs) of severe disease, ≥3 comorbidities, male sex, and vulnerability for the in-hospital death were 1.87 (1.31-2.59), 1.54 (1.11-2.13), 1.46 (1.14-1.87), and 6.93 (1.69-28.27), respectively. Regarding the severity of frailty, the adjusted HR (95% CI) of highest frailty for the in-hospital death was 12.55 (2.96-53.21).
