About

At the emergencies rooms, patients with head trauma meeting one of the NICE criteria, which include antiplatelet inhibitors treatment, are considered as patients with a risk of cerebral haemorrage and are taken systematically for a CT-scanner.

However, there are more and more antiplatelet inhibitor's patient with minor head injury traumas seen at the emergencies room and the efficiency of this NICE criteria is controversial on litterature.

This study aims to determine that the absence of no other NICE criteria than antiplatelet inhibitors is a sufficient condition to eliminate a cerebral haemorrhage for patients with head injury traumas, and conversely, that antiplatelet inhibitors treatment would not be by itself an indication for a CT-scanner.

Full description

Head injuries are a frequent reason for emergency services, and according to studies, they represent between 5% and 10% of patients treated in emergencies. Among them, 90% are minor head injury traumas. NICE criteria has been defined to establish patients who need a CT-scanner because of a risk of cerebral haemorrhage.

NICE criteria include several conditions including taking antiplatelet inhibitors. However, the real risk of cerebral haemorrhage for theses cases is controversial in litterature. In parallel, more and more patients undergoing antiplatelet inhibitor's treatment are seen in emergencies after a head injury trauma.

In routine protocol at the emergency rooms, these patients are seen for a clinical exam and next submitted to a CT-scanner. If the clinician can't detect a cerebral haemorrage, the patient will return at home.

This study aims to determine that the absence of no other NICE criteria than antiplatelet inhibitors treatment is a sufficient condition to eliminate a cerebral haemorrhage for patients with head injury traumas, and conversely, that antiplatelet inhibitors treatment would not be by itself an indication for a CT-scanner.

This is a diagnostic, case-only, prospective, multicenter study with a blinded primary outcome measure assessment.

As described in routine protocol, in this study antiplatelet inhibitor's patients with head injury trauma will be seen for a clinical exam and next submitted to a CT-scanner. After a month, patient will be called by the clinical center to ask about morbidity and mortality. Especially, clinicans will report on the emergence of a cerebral haemorrhage during this month.
