Medico-economic Interest of the Protein S100b in Mild Head Trauma Under Anti-thrombotics

Rennes University Hospital260 enrolled

Overview

Head trauma is a common injury in emergency department. Investigation to search for complication is guided by the clinical examination and the case history, such as taking anti-thrombotics. Cranial computed tomography (CCT) is the gold standard to investigate, and is mandatory in case of antithrombotic drugs. Recently, some biomarkers have proven their utility to rule-out mild head trauma without CCT in the general population. Among these biomarkers, S100β protein has been added in guidelines for mild head trauma. Some studies have found similar data in population taking anticoagulant or antiplatelet drugs. The investigators aim to prove medical utility of S100β protein in population under antithrombotics, by the reduction of CCT use. Then, The investigators hypothesize that the add of S100β protein reduces cost of health care in the management of head injury in that population.

Outcomes

Primary Outcomes

Diagnostic performances are evaluated by AUC

Diagnostic performances of S100β protein in case of mild head trauma for detection of traumatic intracranial lesion in patients under antithrombotic medication compare to cranial computed tomography.

Time frame: 1 day

Diagnostic performances are evaluated by sensibility, specificity

Time frame: 1 day

Diagnostic performances are evaluated by positive and negative predictive values between the strategy with S100β protein compared to the strategy with systematic cranial computed tomography.

Time frame: 1 day
