A New Method for Database Data Quality Evaluation at the Canadian Institute for Health Information (CIHI).
Bibliographic record
Abstract
Information quality (IQ) problems can have severe consequences in the health care sector. Since its inception, the Canadian Institute for Health Information (CIHI) has recognized the importance of information quality and has implemented a new method designed to evaluate the data quality of the numerous CIHI data holdings. The goal of evaluation is to identify data quality priorities for the purpose of data quality improvement. To date, six database evaluations have been conducted and it appears that the evaluation process has been successful in meeting its primary objective. It is concluded that the new method is a useful tool for data quality improvement, especially in the health care sector where data quality improvement can result in better health information and, ultimately, better health.

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.
