Traumatic brain injury in the elderly: A level 1 trauma centre study
Bibliographic record
Abstract
OBJECTIVE: To explore the characteristics and outcome of patients with TBI over 65 years old admitted to an acute care Level 1 Trauma centre in Montreal, Canada. METHODS: Data were retrospectively collected on patients (n = 1812) who were admitted post-TBI to the McGill University Health Centre-Montreal General Hospital from 2000-2011. The cohort was composed of four groups over 65 years old (65-75; 76-85; 86-95; and 96 and more). Outcome measures used were the extended Glasgow Outcome Scale (GOSE) as well as discharge destination. RESULTS: As the patients got older, the odds of having a poor outcome increased (OR = 2.344 for those 75-85 years old, 4.313 for those 86-95 years of age and 3.465 for those aged 96 years of age or older). Also, the proportion of patients going home or going home with out-patient rehabilitation decreased as age increased (p = 0.001 and p < 0.001, respectively). In contrast, the proportion of patients being discharged to long-term care facilities increased significantly as age increased (p < 0.001). CONCLUSION: This descriptive study provides a better understanding of characteristics and outcome of different age groups of patients with TBI all over 65 years old in Montreal, Canada.

How this classification was reachedexpand
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; a candidate call from one teacher head, not a consensus.
