Abstract
BACKGROUND: The aim was to characterize end-of-life care in patients who have had a leg amputated for peripheral artery disease (PAD) or diabetes. METHODS: This was a population-based retrospective cohort study of patients with PAD or diabetes who died in Ontario, Canada, between 2011 and 2017. Those who had a leg amputation within 3 years of death were compared with a control cohort of deceased patients with PAD or diabetes, but without leg amputation. The patients were identified from linked health records within the single-payer healthcare system. Place and cause of death, as well as health services and costs within 90 days of death, were compared between the amputee and control cohorts. Among amputees, multivariable regression models were used to characterize the association between receipt of home palliative care and in-hospital death, as well as time spent in hospital at the end of life. RESULTS: Compared with 213 300 controls, 3113 amputees were less likely to die at home (15·5 versus 24·9 per cent; P < 0·001) and spent a greater number of their last 90 days of life in hospital (median 19 versus 8 days; P < 0·001). Amputees also had higher end-of-life healthcare costs across all sectors. However, receipt of palliative care was less frequent among amputees than controls (inpatient: 13·4 versus 16·8 per cent, P < 0·001; home: 14·5 versus 23·8 per cent, P < 0·001). Among amputees, receipt of home palliative care was associated with a lower likelihood of in-hospital death (odds ratio 0·49, 95 per cent c.i. 0·40 to 0·60) and fewer days in hospital (rate ratio 0·84, 0·76 to 0·93). CONCLUSION: Palliative care is underused after amputation in patients with PAD or diabetes, and could contribute to reducing in-hospital death and time spent in hospital at the end of life.

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 it
