Feasibility of an Audit System for Canadian Sonographers in Generalist Ultrasound
Bibliographic record
Abstract
The purpose of this research was to employ the audit method to measure performance and identify targets of change, setting a template for future large-scale investigations that may inform decisions involving sonographer role expansion in Canada. The authors conducted an audit of 433 sonographic examinations performed in the ultrasound department of a Canadian hospital. Sonographer reports were contrasted with radiologist final reports, and a degree of agreement (DoA) 1 to 4 was assigned to each exam package. In total, 322 of 429 (75%) exam packages were ranked as DoA 1 (complete agreement between sonographer and radiologist), 86 of 429 (20%) were ranked as DoA 2, 16 of 429 (4%) were ranked as DoA 3, and 5 of 429 (1%) were ranked as DoA 4 (significant discrepancy between sonographer and radiologist). The results revealed a 75% agreement between sonographer and radiologist on imaging findings as they are recorded in technical impression sheets and reports. Discrepancies are usually minor and involve the omission of incidental findings by the radiologist.

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.
