Abstract

Assessing patient frailty in the Emergency Department (ED) is crucial; however, triage frailty and comorbidity assessment scores developed in recent years are unsatisfactory. The underlying causes of this phenomenon could reside in the nature of the tools used, which were not designed specifically for the emergency context and, thus, are difficult to adapt to the emergency environment. The objective of this study was to create and internally validate a nomogram for identifying different levels of patient frailty during triage. Multicenter, prospective, observational exploratory study conducted in two ED. The study was conducted from April 1 to October 31, 2022. Following the triage assessment, the nurse collected variables related to the patient's comorbidities and chronic conditions using a predefined form. The primary outcome was the 90-day mortality rate. A total of 1345 patients were enrolled in this study; 6% died within 90 days. In the multivariate analysis, the Charlson Comorbidity Index, an altered motor condition, an altered cognitive condition, an autonomous chronic condition, arrival in an ambulance, and a previous hospitalization within 90 days were independently associated with death. The internal validation of the nomogram reported an area under the receiver operating characteristic of 0.91 (95% CI 0.884-0.937). A nomogram was created for assessing comorbidity and frailty during triage and was demonstrated to be capable of determining comorbidity and frailty in the ED setting. Integrating a tool capable of identifying frail patients at the first triage assessment could improve patient stratification.
