Does the Probability of Survival Calculated by the Trauma and Injury Severity Score Method Accurately Reflect the Severity of Neurotrauma Patients Admitted to Regional Trauma Centers in Korea?

The limitations of using the TRISS method for predicting outcomes in patients with severe neurotrauma are exposed in this study. The TRISS methodology demonstrated a high misclassification rate of approximately 40% in subgroups of patients with GCS less than 9, indicating that it may be less reliable in predicting outcomes for severely injured patients with low GCS. Clinicians and researchers should be cautious when using the TRISS method and consider alternative methods to evaluate patient outcomes and compare the quality of care provided by different trauma centers.
