Fall-related deaths among older adults in British Columbia
Bibliographic record
Abstract
British Columbia (BC) is experiencing a rapidly aging population, with older adults living longer and healthier lives than previous generations. By 2021, there are expected to be over one million British Columbians aged 65 years and older, with most of them living at home in their communities. Falls are the number one cause of injury-related deaths among older adults, with one in three older adults falling each year. Falls, however, are not a normal part of aging and can be prevented. Researchers and policy makers can look to injury data to help determine the types of programs that can reduce the risk of injury from falls. This includes examining patterns in fall-related deaths (mortality trends). Recently we noticed something interesting when comparing fall-related mortality patterns with other provinces. There was an unexpected increase found in the rate of fall-related deaths among older adults in BC between 2008 and 2012, followed by a gradual decline. Upon further investigation, we found that this anomaly is actually the result of a 2010 policy change in how cause of death is captured and recorded, rather than a spike in deaths, highlighting that context is always needed before drawing conclusions from injury data.

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.
