Validity of Korean Triage and Acuity Scale for Predicting In-Hospital Mortality in Patients with Acute Traumatic Brain Injury : A Nationwide Population-Based Study of 2018-2020

KTAS is an effective tool for early risk stratification in acute TBI, particularly for identifying critically ill patients. Retriage supplements the predictive validity of initial KTAS,, supporting its role in guiding clinical decision-making. Further research is warranted to validate KTAS in broader TBI populations and refine its utility for surgical decision-making.
