Abstract
PURPOSE: The Geriatric Trauma Outcome Score (GTOS) is a new prognostic tool used to predict mortality of geriatric trauma patients. We aimed to apply this model to Korean geriatric trauma patients and compare it with the Trauma and Injury Severity Score (TRISS) method. MATERIALS AND METHODS: Patients aged ≥65 years who were admitted to a level 1 trauma center from 2014 to 2018 were included in this study. Data on age, Injury Severity Score (ISS), packed red blood cell transfusion within 24 h, TRISS, admission disposition, mortality, and discharge disposition were collected. We analyzed the validity of GTOS and TRISS by comparing the area under the survival curve. Subgroup analysis for age, admission disposition, and ISS was performed. RESULTS: <0.05). Other subgroup analyses showed equally good power of discrimination for mortality. CONCLUSION: GTOS can be used to predict mortality of severely injured Korean geriatric patients, and also be helpful in deciding whether invasive or aggressive treatments should be administered to them.
