SARS-CoV-2 Outcomes: The Role of Patient Characteristics and Chronic Disease Comorbidities

Several patient demographics such as race/ethnicity and comorbid chronic conditions are associated with severity of illness among COVID-19 patients. This study examines national data of COVID-19 patients to estimate the likelihood that these characteristics are associated with a hospital admission, admission to an intensive care unit (ICU), and length of hospital stay. Using logistic regressions, the authors found that minority populations (Black, Asian, and Hispanic) were 21% to 35% more likely to be hospitalized than Whites. Moreover, patients with multiple chronic conditions also were more likely to be hospitalized, admitted to the ICU, and had longer lengths of stay. Results highlight the need to target vaccines to the most vulnerable populations during COVID-19 but also for future outbreaks.
