A new study which investigated the prognostic performance of head computerised tomography (CT) scoring systems for penetrating traumatic brain injury (pTBI) has found that they demonstrate good-to-excellent performance in six-month outcome prediction. However, the authors say, they do not add independent information to known outcome predictors.
In the study, researchers assessed the prognostic performance of the Marshall CT classification, Rotterdam CT score, Stockholm CT score and the Helsinki CT score in predicting six-month mortality and six-month functional outcome independently and together with known TBI outcome predictors in 75 adults with pTBI at two centres.
The authors reported that the Helsinki CT score showed slightly better performance than the other CT scores for six-month mortality prediction. All CT classification systems demonstrated good performance in predicting six-month unfavourable outcome, with no significant difference between the individual CT scores.
However, the authors noted the classification systems do not significantly improve the performance of a simple model based on age, motor response and pupil responsiveness.
Writing in Acta Neurochirurgica, they said the findings highlight the importance of clinical characteristics in prognosis evaluation of pTBI patients and the possible utility of a more tailored CT scoring system for pTBI.
