Evaluation of the trauma-specific frailty index in geriatric trauma patients according to the new World Health Organization age classification.

Objective: We compared the 15-variable trauma-specific frailty index and traditional injury scoring systems to determine trauma severity and predict discharge disposition in geriatric trauma patients based on the old and new World Health Organization age classifications.

Methods: This prospective, observational, single-center study included geriatric patients aged ≥65 years with blunt trauma. We categorized patients as elderly based on the old or new World Health Organization age classification into group I (aged 65-79 years) and group II (aged ≥a80 years), respectively.
