About: INTRODUCTION: Older subjects have a higher risk of COVID-19 infection and a greater mortality. However, there is a lack of studies evaluating the characteristics of this infection at advanced age. PATIENTS AND METHODS: We studied 404 patients ≥ 75 years (mean age 85.2 ± 5.3 years, 55% males), with PCR-confirmed COVID-19 infection, attended in two hospitals in Madrid (Spain). Patients were followed-up until they were discharged from the hospital or until death. RESULTS: Symptoms started 2 to 7 days before admission, and consisted of fever (64%), cough (59%), and dyspnea (57%). A total of 145 patients (35.9%) died a median of 9 days after hospitalization. In logistic regression analysis, predictive factors of death were age (OR 1.086; 1.015-1.161 per year, p = 0.016), heart rate (1.040; 1.018-1.061 per beat, p < 0.0001), a decline in renal function during hospitalization (OR 7.270; 2.586-20.441, p < 0.0001) and worsening dyspnea during hospitalization (OR 73.616; 30.642-176.857, p < 0.0001). Factors predicting survival were a female sex (OR 0.271; 0.128-0.575, p = 0.001), previous treatment with RAAS inhibitors (OR 0.459; 0.222-0.949, p = 0.036), a higher oxygen saturation at admission (OR 0.901; 0.842-0.963 per percentage point increase, p = 0.002), and a greater platelet count (OR 0.995; 0.991-0.999 per 10(6)/L, p = 0.025). CONCLUSION: Elderly patients with COVID-19 infection have a similar clinical course to younger individuals. Previous treatment with RAAS inhibitors, and demographic, clinical and laboratory data influence prognosis.   Goto Sponge  NotDistinct  Permalink
