Abstract

fetched live from OpenAlex

[Extract]<br/>Alongside the human suffering, covid-19 is also threatening the sustainability of health systems. The continuing costs of the pandemic combined with the impending financial crisis will inevitably mean having to do more with less. The tragedy of the pandemic has paradoxically produced an opportunity to tackle the increasingly recognised challenge of “too much medicine” safely and fairly—to help improve both sustainability and equity in healthcare. This well described problem of unnecessary tests, diagnoses, and treatments causes harm and wastes resources that could be better used for those in genuine need.

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.
