Development of a Multi-Factorial Data Quality Score for Primary Care Electronic Medical Records
Bibliographic record
Abstract
As healthcare providers transitioned from paper-based records to electronic medical records (EMRs), researchers gained access to more patient and care data, with greater detail. Current research regarding Canadian primary care EMR data suggests the quality of data is variable. For researchers who wish to use EMR data, it is important to have a method of evaluating data quality that is applicable to multiple EMR datasets so research quality can be assured. There is currently no unified scoring system for primary care EMR data. This thesis built on previous EMR data quality research by developing and testing a composite measure of data quality using previously-validated quality measures that assessed the data quality domains of completeness, correctness, and currency. A composite data quality score was created and tested using data splitting. This scoring system could be used by researchers to examine EMR data quality and compare data quality across data sources.

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.
