Multivariate Analysis of Risk of In-Hospital Mortality in Hospitalized Older Patients With COVID-19

Variables	OR (95% CI)	p Value
Gender, reference value = female		<.001
Gender = male	1.85 (1.30–2.63)
Adjusted Charlson index, reference value < 7		.65
Adjusted Charlson index ≥ 7	1.02 (0.94–1.11)
ADL, reference value ≥ 4		.002
ADL < 4	1.84 (1.25–2.70)
Asthenia, reference value = no		.02
Asthenia = yes	1.59 (1.08–2.32)
qSOFA, reference value < 2		<.001
qSOFA ≥ 2	2.63 (1.64–4.22)
Specific COVID-19 anomalies on chest CT, reference value = No		.04
	2.60 (1.07–6.46)
Specific COVID-19 anomalies: yes		.005
No chest CT	3.83 (1.50–9.80)

Note: ADL = activities of daily living; AIC = Akaike’s information criterion; CI = confidence interval; CT = computed tomography; ICC = intraclass correlation; OR = odds ratio; qSOFA = quick Sequential Organ Failure Assessment. N = 720; Charlson index = 0.69; 95% CI = 0.69–0.76; ICC = 0.049; AIC = 837.7.
