Insights
Elderly males with COVID-19, especially those with comorbidities like cerebrovascular disease and COPD, face significantly higher mortality risks. Early prevention and critical care are crucial for this vulnerable population.
Area of Science:
- Epidemiology
- Infectious Diseases
- Gerontology
Background:
- The COVID-19 pandemic has caused significant global morbidity and mortality.
- Understanding risk factors for mortality is crucial for effective patient management.
- This study focuses on patients not treated with dexamethasone or remdesivir.
Purpose of the Study:
- To identify risk factors associated with mortality in COVID-19 patients.
- To analyze demographic and comorbidity data across different geographical regions.
- To investigate the impact of age, gender, and comorbidities on COVID-19 survival.
Main Methods:
- Multi-country cohort study analyzing 568 survivors and 507 non-survivors.
- Comparative analysis of demographic data (age, gender) and comorbidities.
- Survival analysis to identify mortality-associated factors and survival time differences.
Main Results:
- Elderly males (≥70 years) were disproportionately represented among non-survivors across China, Europe, and North America.
- Non-survivors exhibited higher incidences of cerebrovascular disease and chronic obstructive pulmonary disease (COPD).
- Age, male gender, shortness of breath, cerebrovascular disease, and COPD were identified as significant mortality-associated factors.
Conclusions:
- Elderly males with COVID-19, particularly those with comorbidities, face a substantially elevated mortality risk.
- Shorter survival times were observed in elderly, male, and comorbid patients.
- Findings underscore the need for targeted early prevention and critical care strategies for elderly populations, especially males with pre-existing conditions.
Abstract:
The COVID-19 pandemic causes severe morbidity and mortality. This multi-country study aimed to explore risk factors that drive mortality in COVID-19 patients who received neither dexamethasone nor remdesivir. We analyzed a cohort of 568 survivors and 507 non-survivors from China, European regions, and North America. Elderly males ≥70 years accounted for only 25% of survivors, but this rate was significantly higher in non-survivors from China (55%), European regions (63%), and North America (47%). Compared with survivors, non-survivors had more incidences of comorbidities such as cerebrovascular disease and chronic obstructive pulmonary disease (COPD, p-values<0.05). Survival analyses revealed age, male gender, shortness of breath, cerebrovascular disease, and COPD as mortality-associated factors. Survival time from symptom onset was significantly shorter in elderly versus young patients (median: 29 versus 62 days), males versus females (median: 46 versus 59 days), and patients with versus without comorbidities (mean: 41 versus 61 days). Mortality risk was higher in elderly males with comorbidities than in young females without comorbidities (p-value<0.01). Elderly male survivors with comorbidities also had longer hospital stays than other survivors (25 versus 18.5 days, p-value<0.01). Overall, the high mortality risk in elderly males with COVID-19-associated comorbidities supports early prevention and critical care for elderly populations.
