Dying of amyotrophic lateral sclerosis
Bibliographic record
Abstract
<h3>Objective</h3> To describe health care service utilization and cost for decedents with and without amyotrophic lateral sclerosis (ALS) in the last year of life. <h3>Methods</h3> Using linked health administrative data, we conducted a retrospective, population-based cohort study of Ontario, Canada, decedents from 2013 to 2015. We examined demographic data, rate of utilization, and cost of health care services in the last year of life. <h3>Results</h3> We identified 283,096 decedents in Ontario, of whom 1,212 (0.42%) had ALS. Decedents with ALS spent 3 times as many days in an intensive care unit (ICU) (mean 6.3 vs 2.1, <i>p</i> < 0.001), and twice as many days using complex continuing care (mean 12.7 vs 6.0, <i>p</i> < 0.001) and home care (mean 99.1 vs 41.3, <i>p</i> < 0.001). A greater percentage of decedents with ALS received palliative home care (44% vs 20%, <i>p</i> < 0.001) and palliative physician home visits (40% vs 18%, <i>p</i> < 0.001) than decedents without ALS. Among decedents with ALS, a palliative physician home visit in the last year of life was associated with reduced adjusted odds of dying in hospital (odds ratio 0.65, 95% confidence interval 0.48–0.89) and fewer days spent in the ICU. Mean cost of care in the last year of life was greater for those with ALS ($68,311.98 vs $55,773.48, <i>p</i> < 0.001). <h3>Conclusions</h3> In this large population-based cohort of decedents, individuals with ALS spent more days in the ICU, received more community-based services, and incurred higher costs of care in the last year of life. A palliative care physician home visit was associated with improved end of life outcomes; however, the majority of patients with ALS did not access such services.

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.
