[Clinical and pharmacological data in COVID-19 hospitalized nonagenarian patients]. / Variables clínicas y farmacológicas de pacientes nonagenarios hospitalizados por COVID-19.

OBJECTIVE: 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. METHODS: 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. RESULTS: 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. CONCLUSIONS: 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.
