CHIP_prediction_rule v.1
Predicts intracranial traumatic CT findings in patients with minor head trauma.
To predict intracranial traumatic CT findings in patients with minor head trauma.
Use in patients at least 16 years old presenting within 24 hours of blunt head trauma and GCS 13–14 (or GCS 15 with at least one of the following: LOC, short-term memory deficit, amnesia, seizure, vomiting, severe headache, intoxication, anticoagulant use or history of coagulopathy, external evidence of injury above the clavicles, neurologic deficit). Evaluation: If ≥1 major criterion OR ≥2 minor criteria are present, CT head is required. Major criteria: Pedestrian or cyclist versus vehicle, ejected from vehicle, vomiting, post-traumatic amnesia ≥4 hours, clinical signs of skull fracture, GCS <15, GCS deterioration of 2 or more points (1 hour after presentation, use of anticoagulant, post-traumatic seizure or age 60 years or more. Minor criteria: Fall from any elevation, persistent anterograde amnesia, post-traumatic amnesia of 2 to <4 hours, contusion of the skull, neurologic deficit, loss of consciousness, GCS deterioration of 1 point (1 hour after presentation) or age 40–60 years.
The Canadian CT Head Rule is recommended over other adult head trauma decision rules, as it is the most widely validated.
