  • a Each injury is allocated to one of six body regions (head/neck, face, chest, abdomen/pelvis, extremities, and skin/general) and is assigned an abbreviated injury scale (AIS) score from 1 to 6 (most severe). The AIS scores of the three most severely injured body regions are squared and added together to calculate the injury severity score (ISS) (2, 18).

  • b MVA, motor vehicle accident.
