The scores are defined for hospitalization within 30 days from COVID-19 diagnosis, and mortality within 74 days of the diagnosis.
Score categorization: Hospitalization: Low risk: score < 39, Intermediate risk: 39 ≤ score < 44, High risk: score ≥ 44. Mortality among hospitalized patients: Low risk: score < 89, Intermediate risk: 89 ≤ score < 92, High risk: score ≥ 92. The prevalence of hospitalization within 30 days from COVID-19 diagnosis in the low, intermediate, and high risk groups were 2.75%, 8.47%, 22.85%, respectively. The incidence of mortality over approximately 3 months among hospitalized patients with COVID-19 diagnosis ranged from zero 0.92% in the low-risk group, to 4.44% in the intermediate- and 26% in the high-risk groups. According to the US Census 2018, the lower median income cutoff ($60 K) represents the lower 62% of the population, and the high-income cutoff ($80 K) represents the top 15% of the population.
