First CT findings and improvement in GOS and GOSE scores 6 and 12 months after severe traumatic brain injury.
OBJECTIVE
To analyse the association between individual initial computerized tomography (CT) scan characteristics and Glasgow Outcome Scale (GOS) and Extended Glasgow Outcome Scale (GOSE) improvement between 6 months and 1 year.


METHODS
Two hundred and twenty-four adult patients with severe traumatic brain injury and Glasgow Coma Scale (GCS) score of 8 or less who were admitted to an intensive care unit were studied. GOS and GOSE scores were obtained 6 and 12 months after injury in 203 subjects. Patients were predominantly male (84%) and median age was 35 years.


RESULTS
Traumatic Coma Data Bank (TCDB) CT classification was associated with GOS/GOSE improvement between 6 months and 1 year, with diffuse injury type I, type II and evacuated mass improving more than diffuse injury type III, type IV and non-evacuated mass; for GOS 43/155 (28%) vs 3/48 (6%) (chi(2) = 9.66, p < 0.01) and for GOSE 71/155 (46%) vs 7/48 (15%) (chi(2) = 15.1, p < 0.01). CT individual abnormalities were not associated with GOS/GOSE improvement, with the exception of subarachnoid haemorrhage, which showed a negative association with GOSE improvement (chi(2) = 4.08, p < 0.05).


CONCLUSIONS
TCDB CT scan classification and subarachnoid haemorrhage were associated with GOS/GOSE improvement from 6-12 months, but individual CT abnormalities were not associated.
