What do prehospital trauma scores predict besides mortality?

Area of Science:

• Trauma care
• Prehospital medicine
• Clinical scoring systems

Background:

• Limited data exists on prehospital triage score predictive capabilities beyond mortality.
• Assessing non-mortality outcomes is crucial for comprehensive trauma patient evaluation.

Purpose of the Study:

• To evaluate the predictive accuracy of prehospital triage scores (MGAP, RTS, T-RTS) for severe injury, prolonged ICU stay, massive hemorrhage, and emergency procedures.
• To compare these scores against the Trauma-Related Injury Severity Score (TRISS).

Main Methods:

• Analysis of two trauma patient cohorts (n=2,363) treated by mobile intensive care units.
• Calculation of Area Under the Receiver Operating Characteristic curves (AUC(ROC)) to assess predictive performance.

Main Results:

• MGAP, RTS, and T-RTS accurately predicted Injury Severity Score >15, prolonged ICU stay or death, and massive hemorrhage.
• These scores demonstrated poor predictive ability for emergency procedure requirement.
• Penetrating trauma, significant colloid administration, hypotension, and tachycardia independently predicted emergency procedures.

Conclusions:

• Prehospital triage scores are valuable for identifying severe injuries, extended ICU stays, and massive hemorrhage.
• Current prehospital triage scores are insufficient for predicting the need for emergency interventions.
• Further research may identify improved predictors for emergency procedures in prehospital trauma care.
