BET 3: Can protein S100B add to current clinical guidelines in adult minor head injury?

Abstract

A short-cut review was carried out to determine whether protein S100B either alone or incorporated into clinical guidelines could be used to identify accurately those adults with mild head injury who had significant brain trauma. Thirty-five papers were found using the reported searches, of which nine presented the best evidence to answer the clinical question. The author, date and country of publication, patient group studied, study type, relevant outcomes, results and study weaknesses of those best papers are shown in table 3. It is concluded that while S100B is a sensitive test for traumatic brain injury, there is no evidence to determine whether it adds value to any current clinical guidelines.
