Physician Practices for Prescribing Supplemental Oxygen in the Palliative Care Setting
Bibliographic record
Abstract
Dyspnea is a disturbing symptom frequently experienced by patients with advanced cancer. Supplemental oxygen is commonly used as palliative treatment in this setting. We undertook a telephone survey of physicians authorized to prescribe home oxygen according to eligibility criteria determined by publicly funded home care service. A clinical case was varied by addition of one to four factors: presence or absence of dyspnea, hypoxemia, private insurance, and a "dummy" factor to give 20 scenarios. Respondents decided whether to prescribe oxygen and rated degree of benefit oxygen would provide. Physician response rate was 81%. Respondents were in complete agreement in 44% of scenarios. The presence of breathlessness or hypoxemia affected the decision to prescribe oxygen; availability of private insurance did not. There was a wide range of perceived benefits to oxygen prescription. In conclusion, physician practices for prescribing supplemental oxygen in the palliative care setting are variable. Further research is needed.

How this classification was reachedexpand
Full frame distilled prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. Learned from the 10,348 direct Codex labels and 10,348 direct Gemma labels. Candidate is the union of thresholded teacher heads; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels or direct frontier model 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 teacher head, not a consensus.
