Clinical evaluation and 'Trauma Team' activation are paramount regardless of the calculated score.
About this calculator
Overview
The Injury Severity Score (ISS) is an anatomical scoring system that provides an overall score for patients with multiple injuries. It correlates with mortality, morbidity, and hospital stay after trauma. The score is calculated as the sum of the squares of the highest AIS (Abbreviated Injury Scale) scores in the three most severely injured body regions.

Pro Tips
External injuries include skin burns, abrasions, and lacerations.
Extremities include the pelvic girdle as well as limbs.
Always prioritize the stabilization of airway, breathing, and circulation (ABCs) over anatomical scoring.

Fun Facts
"Body regions include: Head/Neck, Face, Chest, Abdomen, Extremities, and External."
"AIS levels range from 1 (Minor) to 6 (Unsurvivable)."
"If any body region is assigned an AIS of 6, the total ISS is automatically set to 75."
"A score of 15 or higher is typically used to define 'major trauma'."
