MOTORCYCLE THORACIC TRAUMA SEVERITY SCORE: A NEW TRAUMA SEVERITY SCORE (MTTSS)

MOTORCYCLE THORACIC TRAUMA SEVERITY SCORE DEVELOPMENT AND VALIDATION OF A NOVEL PREDICTIVE TOOL FOR MORTALITY AND PULMONARY COMPLICATIONS

This study aimed to test the hypothesis that a practical, bedside-applicable tool could be developed to help identify patients at high risk of mortality following motorcycle accidents more quickly and facilitate treatment by enabling faster clinical decision-making.

Study Overview

• Status: Recruiting
• Conditions: Mortality; Trauma (Including Fractures); Trauma Centers; Helmet Use; Motorsycle; Severity Score
• Intervention / Treatment: Other: Training set; Other: Test set

Detailed Description

Injuries resulting from motorcycle accidents are one of the leading causes of death worldwide, and rates are increasing. This increase is attributed to the disproportionate vulnerability of riders at the moment of impact, inadequate protective barriers during collisions, motorcycles' ability to reach high speeds and biomechanical exposure. The thoracic cage is the anatomical region most commonly affected in motorcycle accident-related injuries. This study aimed to test the hypothesis that a practical, bedside-applicable tool could be developed to help identify patients at high risk of mortality following motorcycle accidents more quickly and facilitate treatment by enabling faster clinical decision-making.
