Development and External Validation of a Prognostic Tool for COVID-19 Critical Disease	2020-05-11		.txt	text/plain	2858	171	42	The purpose of this study is to develop and externally validate a prognostic model/clinical tool for predicting COVID-19 critical disease at presentation to medical care. 21 This study describes the development and external validation of a multivariate regression model and associated clinical tool to predict risk of COVID-19 critical disease, presented utilizing All rights reserved. For the derivation cohort, a total of 3,208 COVID-19 tests were conducted over the study period, After feature selection, the following factors associated with greatest increased risk of critical disease were used in model training: age, gender, total number of comorbidities (which included cardiovascular disease, coronary artery disease, chronic kidney disease, asthma/chronic obstructive pulmonary disease, diabetes mellitus, hypertension, and obesity), BMI, respiratory All rights reserved. In this study, we developed and externally validated a predictive model and clinical tool that can be used to prognosticate the likelihood of COVID-19 critical disease based on data available early in a patient's presentation.	./cache/cord-348755-2g5gi1du.txt	./txt/cord-348755-2g5gi1du.txt
