Objectives: To develop and implement a radiological scoring system to define a surgically significant mild Traumatic Brain Injury (TBI), stratify neurosurgical referrals and improve communication between referral centres and neurosurgical units. Design: Retrospective single centre case-control analysis of ten continuous months of mild TBI referrals. Setting: A major tertiary neurosurgery centre in England, UK. Participants: All neurosurgical referrals with a mild TBI (GCS 13-15) during the period of 1st January to 30th October 2017 were eligible for the study. 1248 patients were identified during the study period, with 1444 being included in the final analysis. Interventions: All patients CT head results from the referring centres were scored retrospectively using the scoring system and stratified according to their mean score, and if they were accepted for transfer to the neurosurgical centre or managed locally. Main outcome measure: Determine the discriminatory and diagnostic power, sensitivity and specificity of the scoring system for predicting a surgically significant mild TBI. Results: Most patients referred were male (59.4%, N=681), with a mean age of 69 years (SD=21.1). Of the referrals to the neurosurgical centre, 17% ...Continue Reading

Brain Injury & Trauma

brain injury after impact to the head is due to both immediate mechanical effects and delayed responses of neural tissues.
