Harmonizing domiciliary oxygen therapy in Canada
Bibliographic record
Abstract
Domiciliary oxygen therapy is routinely prescribed for patients with chronic respiratory disease and evidence of hypoxemia, including chronic obstructive pulmonary disease (COPD) and interstitial lung disease (ILD). Despite the evidence supporting this practice, there is considerable variability in medical and reimbursement criteria across Canada. Some provinces offer universal financial support toward domiciliary oxygen for those who need it, whereas other provinces provide coverage only if certain income criteria are met. This heterogeneity leads to inequality of care from one region to the next. Surveys of patients, caregivers and healthcare providers such as those recently developed by the Canadian Pulmonary Fibrosis Foundation highlight many of the real-life challenges around providing domiciliary oxygen. The purpose of this paper is to review key evidence around domiciliary oxygen in COPD and ILD, provide an overview of the Canadian landscape, and recommend harmonized financial and medical criteria to improve the equity of care for patients across the country.

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.
