A Comparison Between End-of-Life Home Care Clients With Cancer and Heart Failure in Ontario
Bibliographic record
Abstract
Individuals with heart failure experience complex symptoms and have a poor prognosis, comparable to those with cancer. However, people with heart failure are less likely to be recognized as needing palliative care. We compared seriously ill home care clients with cancer versus those with heart failure to explore differences between them using existing data from the Resident Assessment Instrument for Home Care (RAI-HC). The sample included 1,475 older adults (65+) in Ontario who had a prognosis of less than 6 months or severe health instability. Clients with heart failure were significantly older (p < .0001) and experienced significantly higher rates of impairment in activities of daily living (p = .005), cognitive impairment (p < .0001), and severe health instability (p < .0001), but were significantly less likely to have a prognosis of less than 6 months (p < .0001). Home care clients with heart failure have needs similar to those with cancer yet are typically not identified as having a terminal prognosis.

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.
