Physician Assistants in Canada
Bibliographic record
Abstract
Physician Assistants began working in the Canadian Armed Forces over 50 years ago and were initially called “medical assistants”. The name changed to physician assistants (PAs) in 1991 (1). PAs work in team settings, with an individualized scope of medical practice similar to their supervising physicians. PAs are flexible and nimble in the work assigned based on clinical need, patient volumes, wait times and gaps in the clinical care process. PAs may work shifts and participate in on-call activities. Specialized roles are adopted by PAs who have had the requisite training andexperience as determined by the supervising physician. This includes performing procedures and assisting in the operating room. PAs work under the supervision of physicians and can have multiple supervisors. Supervisors in academic hospitals may delegate some aspects of the supervisory role to physicians in post-graduate training programs such as residents and fellows. Experienced PAs can achieve a high level of autonomy but are not independent practitioners. Legislation governing the medical acts civilian PAs perform is determined at the provincial level and may involve the use of a scope of practice document or medical directives.

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.
