Length of Survival of Patients with Cancer in Hospice: A Retrospective Analysis of Patients Treated at a Major Cancer Center Versus Other Practice Settings
Bibliographic record
Abstract
This is a retrospective study of the length of survival (LOS) in hospice of patients with cancer treated at a major cancer center compared to other treatment sites. Of 670 patients, the 185 (28%) treated at a major cancer center had unique characteristics, including higher median Palliative Performance Score (PPS) at the time of hospice enrollment (45 versus 40, p = 0.009), and longer median LOS in hospice (35 versus 21 days, p = 0.02: log rank test). Additional variables that predicted longer LOS were higher PPS, Medicare or Medicaid, self-referral, unmarried status, and non-executed advance directives. After adjusting survival for PPS with a Cox proportional hazard model, the hazard ratio for PPS remained statistically significant (95% confidence interval [CI]: 0.95-0.97] while that for the treatment site was not (95% CI: 0.73-1.04]. The performance status, and not the treatment site, was the dominant predictor of the LOS of patients with cancer in hospice.

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.
