Which children are still dying from asthma? A 13 year review of pediatric asthma deaths in British Columbia, Canada
Bibliographic record
Abstract
Pediatric deaths from asthma are rare, however a national inquiry into asthma deaths in the United Kingdom, including 28 children, found that 46% of deaths were avoidable. 1 reviewed all pediatric asthma deaths from 2005 to 2018 in the province of British Columbia, Canada to understand if these patients had risk factors for asthma exacerbations. | METHODSPatients with asthma as a cause of their death were identified from: (1) the Coroner's office if asthma was listed on the Coroner's report as an Immediate Cause of Death or as a Condition Contributing to Death (since 2007 all pediatric asthma deaths are reported to the Coroner's Service with a postmortem examination done if the cause of death is not clear) or (2) the Discharge Abstract database at BC Children's Hospital if they had asthma listed as the most responsible or preadmission diagnosis.BC Children's Hospital is the province's only tertiary care pediatric hospital and provides care for the critically ill children in the province.Patients were included if they died between January 2005 and December 2018, were residents of British Columbia, and were aged 0-18 years at time of death.Data from coroner's records which includes records from primary care physicians and hospital charts were reviewed by a pediatric respirologist (C.Y.) to confirm that asthma was the underlying cause of death and to obtain details of previous asthma care.Administrative data on asthma-related hospitalizations, emergency room visits and dispensed prescription medication was obtained from deidentified provincial and national databases.Risk factors were chosen based on those identified in the national asthma guideline 2 and availability of data.Informed consent was not obtained as the subjects were deceased however all clinical information was deidentified and is presented in aggregate or does not contain identifiable information.

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.
