Determination of prognostic factors of mortality in risky groups is essential to improve patient management. The aim of this study is to describe the clinical presentation in patients over 65 years of age with COVID-19 who are followed up at home by a physician and provide insights into the initial prognostic factors in this distinctive population. Material and Methods: This is a retrospective and observational study. Clinical records of the patients aged over 65 years who were visited by the filiation team, including a physician at home, due to the diagnosis of COVID-19 disease within 2 months were reviewed. Factors affecting mortality were examined. Results: Our study included 51 deceased (mean age: 75,1 +/- 9,0 years, 40,2% males), and 102 patients with COVID-19 who survived (mean age: 73,0 +/- 6,9 years, 68,6% male). Platelet count ( < 150.000, OR 7,26, p=0,001), CRP level ( < 4, OR 4,55, p=0,02), albumin level ( OR 3,24, p=0,02), and Troponin I level (OR 0,03, p=0,02) were the strongest predictors for death. When propensity score matching was applied, gender (male, OR 7,14, p=0,02) and platelet count (< 150.000, OR 5,34, p=0,02) were the strongest predictor Discussion: Elderly COVID-19 patients have a high mortality rate. An easily measurable and accessible platelet count may be a predictor of a bad outcome. Close follow-up and timely treatment may significantly reduce mortality in high- risk elderly patients under.eninfo:eu-repo/semantics/openAccessCOVID-19Frail ElderlyAmbulatory CareMortalityArticle13666366810.4328/ACAM.21083WOS:001027513600016N/A
