Absence of an elective on-site neurological service : impact on outcomes in severely injured head trauma patients in a tertiary referral trauma center
Bibliographic record
Abstract
A retrospective study was conducted to compare two groups of patients treated at the Montreal General Hospital (MGH) for traumatic brain injuries (TBI). The time to neurosurgery, vital status and length of stay in the ICU was evaluated in 299 patients treated before (1997-1998), and 307 patients after (2000-2001) an elective neurosurgery service was eliminated from the NIGH. The outcomes were not significantly different between the two groups. There were trends towards a shorter time to neurosurgery in the group treated in 2000-2001 (4.5 hours) compared to the group treated in 1997-1998 (5.5 hours; p=0.32). Mortality and length of stay in the ICU did not significantly differ between the two groups. This study suggests the provision of adequate neurotrauma care with respect to acute outcomes in the absence of an on-site neurosurgery service, at our institution.

Full frame machine prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. The Gemma side is a direct model label for every work in the frame, read from the title-only record. The Codex side is a classifier learned from the 10,348 direct Codex labels and calibrated to design-weighted sample rates; fields without enough sample support carry no Codex call. Candidate is the union of the two sides; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human 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 source (direct Gemma or distilled Codex), not a consensus.
