External Validation of the Traumatic Bleeding Severity Score for the Predictive Accuracy of the Need for Massive Transfusion.

ABSTRACT:

Background

The Traumatic Bleeding Severity Score (TBSS), developed in Japan, has shown high predictive accuracy in internal validation; however, external validation has still not been performed. We conducted the first external validation of the TBSS in Japan and compared it with other massive transfusion (MT) prediction scores.

Methods

This multicenter retrospective study included severe trauma patients (aged ≥ 18 years, Injury Severity Score [ISS] ≥ 16) from 25 tertiary critical care centers (April 2018-March 2019), excluding those with isolated head injury or cardiac arrest on arrival. TBSS's accuracy for predicting MT was analyzed using the area under the curve (AUC). A complete case was the primary approach, with sensitivity analysis using multiple imputed datasets. The
