- Patients with GCS 15 may be admitted for observation if CT imaging is unavailable.
- Adults with certain risk factors should receive a CT head scan within 1 hour or 8 hours after the injury.
- A provisional radiology report should be made available within 1 hour of the scan being performed.
- Children with certain risk factors should receive a CT head scan within 1 hour of the injury.
- Children with only one risk factor should be observed for a minimum of 4 hours after the injury.
