Measuring the effect of Choosing Wisely: an integrated framework to assess campaign impact on low-value care
Bibliographic record
Abstract
The Choosing Wisely campaign began in the USA in 2012 to encourage physicians and patients to discuss inappropriate and potentially harmful tests, treatments and procedures. Since its inception, the campaign has grown substantially and has been adopted by 12 countries around the world. Of great interest to countries implementing the campaign, is the effectiveness of Choosing Wisely to reduce overutilisation. This article presents an integrated measurement framework that may be used to assess the impact of a Choosing Wisely campaign on physician and provider awareness and attitudes on low-value care, provider practice behaviour and overuse of low-value services.

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.
