Clinical Scorecard: Evaluation of the Stockholm Score for Lesion Identification via Computed Tomography in Mild Traumatic Brain Injury: A Preliminary Analysis and Statistical Framework

At a Glance

Key Highlights

• mTBI accounts for 70–90% of all TBI cases; less than 1% require neurosurgical intervention.
• The Stockholm Score aims to provide individualized risk estimation for traumatic ICL and clinically significant lesions in mTBI patients.
• The study uses a large multicenter retrospective cohort (over 40,000 patients planned) with a pilot analysis on 5,000 patients.

Guideline-Based Recommendations

Diagnosis

• Use Glasgow Coma Scale (GCS) scoring (13–15) to classify mTBI severity.
• Perform head CT scans based on clinical decision rules and regional guidelines (e.g., Scandinavian Neurotrauma Committee guidelines).
• Consider brain biomarker S100B sampling to rule out the need for CT in select centers.

Management

• Hospitalize patients with detected intracranial lesions for observation and possible intervention.
• Reverse anticoagulation therapy if indicated.
• Plan repeat head CT scans as clinically necessary.

Monitoring & Follow-up

• Monitor for clinical deterioration that may necessitate neurosurgical intervention, intubation, or other critical care.
• Use standardized protocols for data collection and follow-up in retrospective and prospective cohorts.

Risks

• Low incidence (<1%) of neurosurgical intervention in mTBI patients.
• Potential for missed intracranial lesions if CT is not performed based on validated clinical decision rules.
• Interrater variability in GCS scoring may affect risk stratification.

Patient & Prescribing Data

Adults with mild traumatic brain injury presenting to the ED

Documentation of antiplatelet and anticoagulant therapies is critical due to their association with intracranial lesion risk; dual antiplatelet therapy and ventriculoperitoneal shunts are notable risk factors under investigation.

Clinical Best Practices

• Adhere to established clinical decision rules and regional guidelines for CT imaging in mTBI.
• Use the first documented physician GCS assessment for consistency in classification.
• Collect comprehensive clinical variables including medication history, physical exam findings, and laboratory results to improve risk prediction.
• Implement standardized data collection protocols and utilize electronic medical records and imaging software for accurate data capture.
• Apply multivariable prediction modeling following TRIPOD guidelines to enhance individualized risk estimation.
