Abstract

Background
Coronavirus disease 2019 (COVID-19) can cause multiple acute complications. This study evaluated the long-term functional status of older patients hospitalized for acute COVID-19.
Methods
We analyzed data from a multicenter ambispective cohort study on patients aged >60 years who were hospitalized for COVID-19 at two tertiary care hospitals in Argentina. The participants were contacted by telephone between November 2021 and September 2022 to collect data on their functional status. Ordinal logistic regression was used to identify factors associated with functional limitations after discharge.
Results
Among the 374 included patients, 205 (55%) showed functional limitations, including 58 (28%) who died during follow-up. The factors independently associated with functional limitations were low baseline functional status (odds ratio [OR]=9.19; 95% confidence interval [CI], 3.35–25.17) and admission to the intensive care unit (OR=4.41; 95% CI, 2.28–8.53). Men had lower odds of functional impairment (OR=0.55; 95% CI, 0.35–0.86).
Conclusion
Older patients had high mortality rates and poor functional status at 2 years post-discharge for COVID-19. Several factors at the time of discharge were associated with a higher risk of functional limitations and can be used to identify patients’ long-term needs for support and rehabilitation services.
