Abstract
Background
Elderly patients with COVID-19 disease are at increased risk for adverse outcomes. Current data regarding disease characteristics and outcomes in this population is limited.
Aim
To delineate the adverse factors associated with outcomes of COVID- 19 patients ≥75 years of age.
Design
Retrospective cohort study.
Methods
Patients were classified into mild/moderate, severe/very severe, and critical disease (intubated) based on oxygen requirements. The primary outcome was in-hospital mortality.
Results
355 patients aged ≥75 years hospitalized with COVID-19 between March 19th and April 25th, 2020 were included. Mean age was 84.3 years. One-third of the patients developed critical disease. Mean length of stay was 7.10 days. Vasopressors were required in 27%, with the highest frequency in the critical disease group (74.1%). Overall mortality was 57.2%, with a significant difference between severity groups (mild/moderate disease : 17.4%, severe/very severe disease : 71.3%, critical disease: 94.9%, p < 0.001). Increased age, dementia, and severe/very severe and critical disease groups were each significantly associated with increased odds for mortality while diarrhea was associated with decreased odds for mortality (OR : 0.12, 95% CI : 0.02-0.60, p < 0.05)]. None of the cardiovascular comorbidities were significantly associated with mortality.
Conclusion
Age and dementia are associated with increased odds for mortality in patients ≥75 years of age hospitalized with COVID-19. Those who require intubation have the greatest odds for mortality. Diarrhea as a presenting symptom was associated with lower odds for mortality.
