Brief Summary

Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.

The main objective is to evaluate the feasibility and interest of setting up a protocol for the systematic measurement of the S100B protein in patients with mild traumatic brain injury admitted to the emergency room of Douai hospital in order to reduce the number of unnecessary brain scans. The main evaluation criterion is the percentage of patients admitted to the emergency department of Douai hospital for mild traumatic brain injury, whose protocol for the systematic measurement of the S100B protein would make it possible to avoid the realization of a brain scans for patients with a protein assay S100B ≤ 0.10 µg/L, carried out within 3h of the onset of MCT.

The systematic dosage of the S100B protein in the context of mild traumatic brain injury still does not appear in the recommendations for good practice in 2021. This study will contribute to the reflection on the use of the S100B protein in the development of new recommendations for good practice of mild traumatic brain injury support.

Detailed Description

Dive into the extended narrative that explains the scientific background, objectives, and procedures in greater depth.

This is an observational, prospective, monocentric study. This study concerns patients over 18 years of age treated in the emergency room of Douai hospital for mild traumatic brain injury treated within 3 hours following the head trauma according to the Jéle et al classification and who have no history of melanoma.

After verification of the patient's eligibility criteria for participation in this study, information relating to the research in order to obtain their authorization to participate in the research.

Once authorization has been obtained, an additional tube of blood is collected when drawing blood samples from the patient as part of their care.

Data are collected and a brain scan performed during the treatment and this is used to fill in the research data collection sheet.

The data used in this research come from the direct questioning of patients. They are recorded on a paper form or in a computerized medical record.

When the patient has been included in the trial the relevant data obtained from the direct questioning are taken from the sources indicated above and are entered on a data collection sheet specifically designed for this research.

The collection sheet will be placed in a dedicated tray and will be collected each week from the emergency room.The data will be compiled in EXCEL ® software secured by a password. This file is hosted on the Douai hospital center server with restricted access.

The files are protected by a password containing 8 characters (uppercase letters, lowercase letters and numbers), known only to the investigator, the person collecting the data, the clinical research assistant in charge of the study and the biostatistician in charge of data analysis.

To meet the main objective, the two-sided 95% confidence interval of the observed percentage of patients admitted to the emergency room of the Douai hospital for mild traumatic brain injury with a brain scan classified as avoidable by the S100B protein assay protocol will be calculated by the exact Clopper-Pearson method.
