An umbrella systematic review, including a meta-analysis examining the association between patients’ underlying conditions and severity (defined as need for hospitalization) and mortality of COVID-19, was performed. Studies were included if they reported pooled risk estimates of at least three underlying determinants for hospitalization, critical disease (ICU admission, mechanical ventilation), and hospital mortality in patients diagnosed with SARS-CoV-2 infection. Evidence was summarized as pooled odds ratios (pOR) for disease outcomes with 95% confidence intervals (95% CI). Sixteen systematic reviews investigating the possible associations of comorbidities with severity or death from COVID-19 disease were included. Hospitalization was associated with age > 60 years (pOR 3.50; 95% CI 2.97−4.36), smoking habit (pOR 3.50; 95% CI 2.97−4.36), and chronic pulmonary disease (pOR 2.94; 95% CI 2.14−4.04). Chronic pulmonary disease (pOR 2.82; 95% CI 1.92−4.14), cerebrovascular disease (pOR 2.74; 95% CI 1.59−4.74), and cardiovascular disease (pOR 2.44; 95% CI 1.97−3.01) were likely to be associated with increased risk of critical COVID-19. The highest risk of mortality was associated with cardiovascular disease (pOR 3.59; 95% CI 2.83−4.56), cerebrovascular disease (pOR 3.11; 95% CI 2.35−4.11), and chronic renal disease (pOR 3.02; 95% CI 2.61−3.49). In conclusion, this umbrella systematic review provides a comprehensive summary of meta-analyses examining the impact of patients’ characteristics on COVID-19 outcomes. Elderly patients and those cardiovascular, cerebrovascular, and chronic renal disease should be prioritized for pre-exposure and post-exposure prophylaxis and early treatment.
