Overview

Each year, approximately 69 million people worldwide suffer from traumatic brain injuries (TBI), representing a significant burden on public health, society, and the economy. Timely and accurate care can influence short-, medium-, and long-term outcomes, making the reduction of diagnostic delays crucial. TBI diagnostics require careful consideration, as initial evaluations may differ from final assessments, and patient conditions may evolve over time. In this monocentric, observational, post-market follow-up study we aim to evaluate the Abbott i-STAT™ TBI Plasma Test in detecting circulating brain biomarkers (GFAP and UCH-L1) in adult patients with TBI. The study involves recruiting 200 adult patients (aged 18-65 years) presenting to the emergency department with TBI over a two-year period. For each participant, a blood sample will be collected as part of routine clinical care and analyzed using the Abbott i-STAT™ TBI Plasma Test within 12 hours of the trauma. The results will be compared with those obtained from cranial CT scans, the gold standard for diagnosing intracranial injuries. Specifically, the study aims to assess the diagnostic accuracy of the test in excluding intracranial injuries, particularly in cases of mild TBI, and to explore potential correlations between biomarker presence and injury severity. No additional procedures beyond routine clinical care are required, and all collected data will be used exclusively for the study's predefined objectives.

Inclusion Criteria: * Patients aged 18 to 65, male and female, presenting to the emergency department due to TBI, defined as trauma caused by an external force leading to temporary or permanent alterations in consciousness and/or neurological function. TBI severity is evaluated using the Glasgow Coma Scale (GCS). * Sign of informed consent by patient or legal tutor Exclusion Criteria: * Pediatric patients (\<18 years). * Patients \>65 years, to avoid potential confounding factors such as elevated GFAP levels associated with Alzheimer's disease.

Outcomes

Primary Outcomes

Evaluation of the real-world effectiveness of the innovative technology

Concordance Between Abbott i-STAT™ TBI Plasma Test Results and Cranial CT Scan in mTBI Cases. The primary outcome measure is the percentage agreement between the qualitative result of the Abbott i-STAT™ TBI Plasma Test (positive or negative) and the presence or absence of traumatic brain injury (TBI) or intracranial haemorrhages detected by cranial CT scan in patients with mild traumatic brain injury (mTBI).

Time frame: T1: first blood sample for biomarker testing and CT scan within 12 hours of trauma; T2: second blood sample for biomarker testing and CT scan at 12 to 24 hours post-initial evaluation, if clinically indicated due to neurological deterioration.
