Abstract

fetched live from OpenAlex

Medication-related adverse events are a major cause of disability and death, 1 and one of the most common reasons that patients attend hospital emergency departments. 2Much of this harm is preventable, either because a less hazardous treatment is available, the medicine is not really needed, or it is inappropriate for this specific patient.Many initiatives exist to improve medicine use.Schiff et al 3 call for a more judicious and precautionary approach to prescribing, with a focus on long-term as well as short-term health.To judge a medicine's net benefit to a patient, prescribers need comprehensive, accurate information on potential harmful as well as beneficial effects.Given the importance of medicines in treatment, information on harm is surprisingly inconsistent and elusive.Approved product information describes adverse events experienced by patients in premarket studies as well as new safety signals once a drug is marketed.In their article, 'Speaking the same language?International variations in the safety information accompanying top-selling prescription drugs', Kesselheim et al 4 describe differences in numbers and types of adverse events in product information for the same 20 top-selling medicines in the US, UK, Canada and Australia.There is no reason to suspect that Americans, Australians, Canadians or the English differ in vulnerability to harm from medicines.As well as numbers of events, individual adverse events-including life-threatening harm-were inconsistently listed.The size of patient safety populations on which assessments were based ranged widely, from a median of 3563 in Australia to 7819 in the UK. 4 This was product information for the same medicines, produced by the same manufacturers, and obtained at the same time.Regulatory warnings of serious risks also differed:

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.
