Access to cardiac catheterization services in a rural-urban setting in northern British Columbia: Examining the impact of time-delay to PCI on patient outcomes and whether the sickest go the quickest..
Bibliographic record
Abstract
This thesis describes the results of a study exploring patient access to percutaneous coronary intervention (PCI) in a rural-urban setting in northern British Columbia, Canada. It specifically examines: 1) whether longer times to treatment (>120 mins) are associated with higher adverse outcomes (death, re-infarction, heart failure, or stroke) in the UA, NSTEMI and STEMI groups within 30-days and 1-year of hospital admission and 2) whether patients most at risk using the Global Registry of Acute Coronary Events (GRACE) risk score receive PCI faster in the UA, NSTEMI, and STEMI groups. Data were collected through retrospective medical chart reviews. Times to treatment and adverse outcomes data are provided although quantitative analysis of this association was not performed. It was determined that the only significant predictor of time to PCI was age and patients were not transferred according to their risk status. Thus it can be concluded that this exploratory study provided valuable real-time feedback for cardiac services in this region and is a basis for further longitudinal investigation in this area. --Leaf ii.

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.
