Traumatic brain injury (TBI) is a complex disorder that comprises a spectrum of intracranial pathologies, many of which present diagnostic challenges. Detection of intracranial injuries after TBI relies on head CT, which is overused and resource intensive. Prior studies have shown the potential for blood-based brain injury biomarkers to predict the absence of intracranial injury after TBI and aid in reducing unnecessary head CT use. Furthermore, plasma biomarker concentrations in the acute phase after TBI identified patients with a suspected TBI and normal head CT who had detectable pathology on MRI. However, most of the current studies are based on the European and American population, and whether the research results are applicable to the Chinese population remains to be studied. Therefore, the investigators will carry out multi-center and large sample research based on the Chinese population, screen the optimal diagnostic and prognosis recognition biomarkers and analyze the diagnostic critical cutoff values, so as to provide a substantial basis for clinical diagnosis and prognosis recognition.
