Variations in the Use of Emergency Departments in Alberta's Capital Health Region 1998–2000
Bibliographic record
Abstract
The objectives of this study were to describe the utilization of emergency departments in the Capital Health region, Alberta, between 1998 and 2000, and temporal variations in emergency department utilization by month, day of week, and time of day in 2000. Between 1998 and 2000, the annual number of visits to emergency departments in the region increased by six percent. The mean length of stay, median length of stay and the number of patients who left without being seen increased by six minutes, eight minutes, and 4,442 patients respectively. Variations in the number of visits, mean and median lengths of stay, and numbers of patients who left without being seen by month, day of week, and time of day were modest except for patients who left without being seen. Service pressures in Capital Health emergency departments continue to exist. Temporal variations in service pressures were small. Causes of emergency department pressures are multiple and interrelated. Therefore, system-wide changes should be considered in addressing emergency department pressures.

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.
