- TBI is associated with extracranial injuries in about 35% of cases.
- The Abbreviation Injury Score (AIS).
- Severity is scored for six body regions:
- External (skin),
- Head/ neck (including brain injury),
- Thorax,
- Abdomen/ pelvic contents,
- Spine, and
- Extremities.
- The severity score can range from 1 to 5
- 1 is minor
- 2 is moderate
- 3 is serious
- 4 is severe
- 5 is critical
- 6 is likely un-survivable
- Injury Severity Score (Baker et al., 1974)
- Aims to summarize the total burden of injury by adding the quadratic scores of the three body regions with the highest score
