Rapid assessment tools can enhance early trauma management and improve patient outcomes.

• Massive transfusion was needed in 19.7% of trauma patients, primarily due to firearm injuries.
• The shock index showed the best predictive accuracy for transfusion needs (AUC=0.911).
• The trauma-related injury severity score (TRISS) was the most effective for predicting in-hospital mortality (AUC=0.975).

These findings underscore the importance of using validated scoring systems to guide therapeutic decisions in trauma surgery.
