Abstract

fetched live from OpenAlex

The rise in harms associated with opioids is an issue of increasing public health importance in Canada. The Government of Canada recently reported 2,816 apparent opioid-related deaths across the country in 2016. Recent 2017 data show that deaths involving fentanyl-related opioids have doubled from January to March as compared to the same time period in 2016 (Government of Canada 2017). Additional measures that provide a better understanding of opioid-related harms, such as hospitalizations and emergency department (ED) visits, are a high priority. The objective of this study is to present pan-Canadian data on hospitalizations and ED visits because of opioid poisoning.

Fetched live from OpenAlex and de-inverted. Abstracts are not stored in this database: the inverted indexes are 8.6 GB of the frame’s 9.3 GB of text, and the host has 13 GB free.

Not 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.
