IntroductionCurrently, there is uncertainty about which frailty scale is most appropriate and valid for use in the emergency department. The objective of this study was to compare the most commonly used frailty scales in triage and evaluate their performance.MethodsThis prospective, single-center observational study was conducted from June to December 2023. Data collection spanned 80 days, during which the triage nurse recorded frailty scales using the Clinical Frailty Scale, Identification of Seniors at Risk, Program of Research to Integrate the Service for the Maintenance of Autonomy 7 (PRISMA-7), and the Triage Frailty and Comorbidity tool. The Clinical Frailty Scale, Identification of Seniors at Risk, and PRISMA-7 were used for patients aged >65 years, whereas the Triage Frailty and Comorbidity tool was applied to all patients presenting to the emergency department. The scales were compared using the area under the receiver operating characteristic curve for 90-day mortality, 30-day mortality, and hospitalization.ResultsA total of 1270 patients were enrolled during the study period. In comparing the receiver operating characteristic curves, the Triage Frailty and Comorbidity tool demonstrated a receiver operating characteristic curve of 0.894 (95% CI: 0.858-0.929), whereas the Clinical Frailty Scale had 0.826 (95% CI: 0.762-0.890), PRISMA-7 had 0.814 (95% CI: 0.751-0.876), and Identification of Seniors at Risk had 0.821 (95% CI: 0.759-0.882), with a comparison P value of 0.03. The Triage Frailty and Comorbidity tool also significantly outperformed the other scales for 90-day mortality, 30-day mortality, and hospitalization across the overall population. Considering only the population aged >65 years, it identifies frail patients equally well as the other tools.DiscussionThe findings of this study suggest that the Triage Frailty and Comorbidity tool is a valid instrument for assessing frailty in the emergency department. Moreover, among the scales used, it is the only 1 that considers the entire adult population, not just those aged >65 years, making it more inclusive for a setting such as the emergency department.Copyright © 2024 Emergency Nurses Association.
