Beskrivelse
Inclusion
- Age ≥18 years at the time of the emergency department visit.
- Presentation to a participating emergency department following a traumatic injury mechanism (motor vehicle collision, fall from height, assault, head injury/head trauma/head strike, struck by or against an object, facial injury or laceration, or other general trauma). Presentations may also include alcohol intoxication or syncope when associated with a suspected traumatic brain injury.
- Evidence of potential head or brain injury, defined as (i) the head being struck by an object, (ii) the head striking a hard object or surface, (iii) exposure of the brain to significant acceleration/deceleration forces, or (iv) clinician documentation that the patient was evaluated for suspected traumatic brain injury.
- Glasgow Coma Scale (GCS) score of 13-15 at presentation.
- Presentation to the emergency department within 24 hours of injury.
Exclusion Criteria:
- Planned computed tomography (CT) imaging of the maxillofacial bones, chest, abdomen, or pelvis during the ED encounter AND clinicians do not intend to avoid brain CT imaging even if the biomarker test is negative.
- Current use of anticoagulant or antiplatelet therapy, including but not limited to: Warfarin, Factor Xa inhibitors (e.g., apixaban [Eliquis], rivaroxaban [Xarelto]), Clopidogrel, Ticagrelor.
- Presentation >24 hours after injury, due to the declining diagnostic sensitivity of Glial Fibrillary Acidic Protein (GFAP) and Carboxy-terminal Hydrolase L1 (UCH-L1) beyond this time window.

Aktiv komparator: Clinical Pathway 2: Clinical Guidelines Only
Clinical Guidelines Only (Canadian Head CT Decision Rule)
|
During the baseline phase, sites will rely solely on established clinical guidelines to guide brain CT utilization in patients with suspected TBI.
Specifically, providers will apply the Canadian CT Head Rule, a validated decision instrument that identifies patients at high risk for clinically important brain injury who require CT imaging.
All sites will begin in this Guidelines-Only baseline phase and will continue using this approach until their assigned transition to the Guidelines + Biomarkers phase.
Sites will transition in three waves, with two sites transitioning every six months.
|
|
Eksperimentel: Clinical Pathway 1: Guidelines + Biomarkers
Canadian Head CT Decision Rule plus whole blood Glial Fibrillary Acidic Protein (GFAP) and Ubiquitin Carboxy-Terminal Hydrolase L1 (UCH-L1) measurement using the iSTAT.
|
Patients will be managed using an algorithm that integrates the Canadian Head CT Rule (CHCR) with iSTAT whole-blood GFAP and UCH-L1 testing.
Patients who meet CHCR criteria for CT imaging and those whose CT imaging decision-making is not covered by CHCR (e.g., no loss of consciousness or amnesia) will receive iSTAT testing.
Sites will be assigned to one of three implementation waves, with two sites transitioning to the Guidelines + Biomarkers phase every six months.
Prior to their assigned transition, sites will continue to use guidelines alone.
Once a site transitions to the Guidelines + Biomarkers phase, the integrated biomarker-guided algorithm will become the standard-of-care protocol at that site for eligible patients and will remain the standard of care for the remainder of the study.
