Health Care Utilization in Canada: Twenty-five Years of Evidence
Bibliographic record
Abstract
A plethora of literature links socioeconomic status (SES) to health and health care utilization. Recent anecdotal evidence indicates that Canadians believe their access to health care is diminishing. This study describes health care utilization patterns for services provided under public health insurance (physicians, specialists, and hospitals) in Canada between 1978 and 2003. The relationship between SES and utilization, controlling for health and demographic characteristics, is examined to investigate whether changes in the equity of utilization have occurred over time. Results indicate that SES inequities in utilization are apparent, appearing to be more relevant in initial contact with the system than in the number of visits. Specialists' services are particularly problematic and becoming more so over time.

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.
