Early outcome in patients with traumatic brain injury, pre-injury alcohol abuse and intoxication at time of injury
Bibliographic record
Abstract
PRIMARY OBJECTIVE: To investigate the relationship between pre-injury alcohol abuse and intoxication at time of injury on duration of post-traumatic amnesia (PTA) as well as on early functional and neurobehavioural outcomes in persons with traumatic brain injury (TBI) hospitalized in an acute care setting. METHODS AND PROCEDURE: Sixty persons with mild, moderate and severe TBI admitted to the intensive care unit were part of this retrospective study. MAIN OUTCOMES: Duration of PTA, length of stay (LOS), Extended Glasgow Outcome Scale (GOS-E) score, the FIM dagger score as well as early neuropsychological outcome measured by the Neurobehavioural Rating Scale Revised (NBRS-R). RESULTS: 2-factor ANOVAs and chi-squares tests showed that PTA and LOS were significantly longer in the group of patients with pre-injury alcohol abuse, regardless of whether they were intoxicated or not at the time of injury. Moreover, the FIM total and cognitive scores were significantly higher for the group intoxicated on admission compared to the sober group. However, GOS-E scores and results on the NBRS-R were similar. CONCLUSIONS: Despite a longer PTA and LOS, global and neurobehavioural outcomes at discharge from acute care were not different for those with pre-injury alcohol abuse.

Full frame distilled prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. Learned from the 10,348 direct Codex labels and 10,348 direct Gemma labels. Candidate is the union of thresholded teacher heads; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels or direct frontier model labels.

Machine scores (provisional)
The two teacher heads of the student model, read on this work. A score orders the frame for review; it never asserts a category, and the validation status ships verbatim with every row.
Baseline scores from an immature model (maturity gate not passed, 7 training rounds). Scores rank; they never assert a category.
score_only:v0-immature-baseline · verbatim from the scoring run: score_only means the number may rank works, and no category label ships from itClassification
machine, unvalidatedMachine predicted; both teacher heads agree on what is shown here.
