Clinical and pharmacological data in COVID-19 hospitalized nonagenarian patients

Despite the impact of SARS-CoV-2 infection in geriatrics, data on nonagenarian patients is scarce. The aim of this study is to describe the clinical features of COVID19-diagnosed nonagenarians, as well as its clinical evolution and therapeutic response. Retrospective observational study of nonagenarians, admitted for COVID-19. Sociodemographic and clinical variables were registered, including previous polypharmacy. Blood analysis data and COVID-19-specific treatment were registered. A total of 79 patients were included, with 50.6% (40 patients) of mortality. None of the comorbidities registered correlated with mortality, which was significantly higher among patients with moderate/complete functional dependence, compared to those mild-dependents/independents (59.5% vs 40.5%; p=0.015). Most prescribed drugs were hydroxychloroquine/chloroquine and azithromycin. Non-survivors presented higher counts of leukocytes and neutrophils, and higher lymphopenia. Nonagenarians with functional dependence presented higher mortality, irrespective of comorbidities or treatment received. Implementing an integral geriatric evaluation would enhance the implementation of personalized therapeutic strategies for nonagenarians.
