About

The PreTBI I study will investigate whether prehospital blood samples drawn already in the ambulance can rule-out intracranial lesions in patients suffering head trauma. The study aims to improve triage and treatment of patients suffering mild head trauma, who are considered low-risk patients. These patients do not always benefit from hospitalization, but are nevertheless admitted on precaution, as clinical assesment can be difficult.

Hypotheses:

  1. A prehospital measurement of serum S100B ≤ 0,10 microgram/L in mild TBI patients rules out traumatic intracranial lesion with a sensitivity >97%.
  2. A prehospital measurement of serum GFAP (glial acidic fibrillary protein) in mild TBI patients rules out traumatic intracranial lesion with sensitivity >97% and results in lower false positive rate than S100B.
  3. Prehospital measurements of both GFAP and S100B results in lower false positive rates than in-hospital measurements.

Inclusion criteria

  • Patients presenting with Glasgow Coma Score (GCS) ≥13-15 and a loss of consciousness for less than 30 min and/or alteration of mental state (being dazed, confused or disorientated) and/or loss of memory for events immediately before and/or after the trauma. The emergency medical service staff will be guided through the inclusion and consent procedures by a simple tablet algorithm.
