The effect of frailty on survival in patients with COVID-19 (COPE): a multicentre, European, observational cohort study

Study (n=1564) noted disease outcomes were better predicted by frailty than either age/comorbidity (compared with clinical frailty scale 1–2, HRs for time from hospital admission to death were 1.55 (95% CI 1.00–2.41) for 3–4; 1.83 (1.15–2.91) for 5–6, and 2.39 (1.50–3.81) for 7–9
