ABSTRACT
Aim: Data on the outpatient follow-up of COVID-19 cases is still scarce. Also, the significance of the ROX index in decision-making for hospitalization in the ambulatory COVID-19 cases remains unknown. The aim of this study is to determine the general characteristics of COVID-19 patients treated as outpatients and to investigate whether the ROX index is applicable in hospitalization decisions. Material(s) and Method(s): This retrospective cohort study was conducted in confirmed adult COVID-19 cases between 15 October 2020 and 01 March 2021. A total of 5240 confirmed COVID-19 patients were included in the present study. Factors affecting hospitalization were investigated. Result(s): The study population was divided into two groups as those who require hospitalization (n=672) and those who did not (n=4568). The number of male patients and the mean age of the patients were significantly higher in hospitalized patients group (p=0.046, p<0.001). ROX index that was calculated at the home visit on the third day of disease was found significantly lower in the group of hospitalized patients (p<0.001). There was a significant correlation between ROX index and inflammatory biomarkers in the present study (p<0.001). The ROX index was found the most accurate parameter for decision-making for hospitalization in ambulatory COVID-19 patients (AUC=0.794 CI=0.773-0.814, p<0.001). Discussion(s): The ROX index can be a useful and objective clinical tool for decision making for hospitalization in the ambulatory COVID-19 cases.Copyright © 2022, Derman Medical Publishing.

ABSTRACT
Aim: The majority of the patients with COVID-19 are followed ambulatory. 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(s) and Method(s): 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. Result(s): 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 predictors. Discussion(s): 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.Copyright © 2022, Derman Medical Publishing. All rights reserved.
