5.3 Does early referral to a multidisciplinary concussion clinic improve outcomes in sport-related concussion?
Bibliographic record
Abstract
Objective To identify whether early referral to a multidisciplinary health care team improves total symptom duration and reduces treatment duration following a diagnosis of sport-related concussion (SRC). Design Retrospective chart audit. Setting Community based tertiary multidisciplinary medical clinic; Patients seen between January 2013 and August 2016. Participants 53 patients with SRC were analyzed. Outcome Measures Treatment duration and total symptom duration. Main Results Mean age of participants was 19.5 years (32% female), mean duration prior to SRC assessment was 27.8 days for all groups, mean treatment duration was 66.1 days and mean total symptom duration was 94.0 days. Three groups were made based on time of assessment (0–14 days, 15–42 days, and 43–90 days). A MANOVA test was performed to compare treatment duration and symptom duration between each of the groups. Group 1 was found to have significantly shorter symptom duration compared to groups 2 and 3 (p<0.05); group 2 was also statistically different from group 3 (p<0.05). Group 1 was found to have significantly shorter treatment duration than group 3 (p<0.05); groups 1 and 2 were not statistically different, nor were groups 2 and 3. Conclusions These findings show that individuals seen earlier following their SRC have a shorter total symptom duration. It also demonstrates that individuals seen earlier (<14 days) have a shorter treatment duration than those seen later (43–90 days). We would recommend an early referral to a multidisciplinary concussion clinic after the diagnosis of SRC is made.

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.
