Patient costs and patient flow after implementation of S100B in Scandinavian head trauma guidelines.

Introduction: The serum biomarker S100B has been implemented in the Scandinavian Neurotrauma Committee (SNC) 2013 Head Injury Guidelines for patients classified with mild head injury (MHI). Patients with a serum S100B level less-than 0.10 μg/l sampled within six hours after trauma can be discharged without further observation or investigation.
