Background

There is a dearth of epidemiological data on ethnic disparities among older patients with COVID-19. The objective of this study was to characterize ethnic differences in clinical presentation and outcomes from COVID-19 among older U.S. adults.

Methods

This was a retrospective cohort study within two geriatric emergency departments (GEDs) at a large academic health system. One hundred patients 65 years or older who visited a GED between March 10, 2020 and August 9, 2020 and tested positive for COVID-19 were examined. Electronic medical records were used to determine presenting COVID-19-related symptoms, comorbidities, and clinical outcomes. Descriptive statistics are reported with associated 95% confidence intervals (CIs).

Results

In the overall sample, mean age was 75.9 years; 18% were 85 years or older; 50% were male; and 46.0% were Hispanic. Relative to non-Hispanic patients with COVID-19, Hispanic patients with COVID-19 had a higher percentage of shortness of breath (78.3% vs. 51.9%; difference: 26.4%; 95% CI 7.6-42.5%), pneumonia (82.6% vs. 50.0%; difference: 32.6%; 95% CI 14.1-47.9%), acute respiratory distress syndrome (13.0% vs. 1.9%; difference: 11.1%; 95% CI 0.7-23.9%), and acute kidney failure (41.3% vs. 22.2%; difference: 19.1%; 95% CI 0.9-36.0%). Rates of other poor outcomes, including hospitalization, intensive care unit (ICU) admission, return visits to the GED within 30 days of discharge, or death, did not significantly differ between Hispanic and non-Hispanic patients with COVID-19.

Conclusions

These preliminary data show that older Hispanic patients relative to non-Hispanic patients with COVID-19 presenting to a GED did not experience worse outcomes, including hospitalization, ICU admission, 30-day return visits to the GED, or death.
