Adherence to Return-to-Play Guidelines Following a Sport-Induced Concussion
Bibliographic record
Abstract
Two studies were conducted in which compliance to Canadian Hockey Association concussion management guidelines was assessed via response to questionnaires. The first study, conducted in both the 2001 and 2002 hockey seasons, involved elite male and female youth hockey players in the British Columbia Best Ever Program. Over 40% of the under 16-year-old males and 37% of the under 18-year-old females reported having sustained a concussion. In the 2001 male cohort, 18% of the concussions resulted in loss of consciousness (LOC), yet 50% of those indicated they returned to the same game. The second study, involving athletes in the Pacific International Junior Hockey League, indicated that 24% of the 163 athletes sustained a concussion within the last year. Out of the 12 who reported LOC, three of those returned to the same game, while only three were seen by a medical doctor prior to return to play. The results suggest that there remains considerable room for improvement with respect to adherence to return to play guidelines.

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.
