How this is calculated
- Items
- 7 criteria in GCS-15 minor head injury: headache, vomiting, age > 60, intoxication, anterograde amnesia, trauma above the clavicles, seizure.
- Rule
- any single positive criterion indicates a head CT; 100% sensitive but low specificity, flagging any CT finding rather than only clinically important injury.
