BackgroundOlder adults living with frailty who require treatment in hospitals are increasingly seen in emergency departments (EDs).ObjectiveThis study investigated the effects of frailty severity according to the Clinical Frailty Scale (CFS) on adverse outcomes and length of stay in the ED before intensive care unit (ICU) admission.MethodsWe conducted this prospective observational study with patients 65 years or older and admitted to the ICU from March 1, 2021 to December 31, 2022. We divided the patients into four groups according to their CFS scores. We determined the effects of frailty severity on length of ED stay and clinical outcomes using logistic regression analysis.ResultsOf the 920 patients included in the study, 25.4% were nonfrail, 26.2% had mild frailty, 25.9% had moderate frailty, and 22.5% had severe frailty. In the regression analysis, compared with those who were nonfrail, the length of ED stay was significantly longer for those with moderate frailty (odds ratio [OR] 2.13; 95% confidence interval [CI] 1.63-2.90) or severe frailty (OR 3.32; 95% CI 1.92-3.87), but the result was not significant for those with mild frailty (OR 1.65; 95% CI 1.21-2.45). ICU mortality was significantly higher among patients with mild, moderate, or severe frailty than among those who were nonfrail.ConclusionsWe found CFS score to be a predictor of length of ED stay and adverse outcomes. Accordingly, CFS evaluation can provide an idea of the length of ED stay and the likelihood of adverse outcomes.Copyright © 2023 Elsevier Inc. All rights reserved.
