A simplified emergency trauma score for predicting mortality in emergency setting

Area of Science:

• Emergency Medicine
• Trauma Surgery
• Public Health

Background:

• Existing trauma scoring systems often require data unavailable in emergency settings, delaying critical treatment.
• Lack of readily available injury severity measures complicates pre-hospital and emergency room patient assessment.

Purpose of the Study:

• To develop a Simplified Emergency Trauma Score (SETS) for injury severity assessment, triage, and mortality prediction in Hong Kong.
• To create a trauma scoring system utilizing parameters accessible in emergency settings.

Main Methods:

• Retrospective analysis of trauma patient records from the Hong Kong Trauma Registry.
• Univariate analysis to identify mortality predictors, followed by binary logistic regression to develop the SETS equation.
• Identified key parameters: age, Glasgow Coma Scale, respiratory rate, and ACS mechanism of injury.

Main Results:

• The SETS equation was developed using four key parameters.
• At a SETS score cutoff of 60, sensitivity was 64% and specificity was 98%.
• The area under the receiver operating characteristic curve was 0.939, demonstrating high performance comparable to existing trauma scores.

Conclusions:

• The Simplified Emergency Trauma Score (SETS) is a relevant and effective tool for Hong Kong's emergency settings.
• The study suggests developing similar context-specific trauma scoring systems globally.
• Accessible trauma scoring systems are crucial for efficient patient triage in congested emergency environments.
