Abstract

fetched live from OpenAlex

Governments and health agencies in Australia, Canada and the United Kingdom (UK) have implemented changes to drug policy, regulation and/or legislation for reducing increasing rates of dependency, overdose and other harms associated with prescription and over-the-counter opioid drugs, and supporting their medicinal use. However, there has been no systematic evaluation of empirical evidence on the effectiveness of the drug policy changes. A systematic review of studies was conducted to assess the evidence. Studies included peer-reviewed and grey literature. The findings of studies were synthesised to identify common features and outcomes of changes to drug policy, including reductions in overdose, death and other indicators of effectiveness. There were 21 studies that met review criteria, and were of changes that generally aimed to: increase access to treatment for issues with opioid drugs; or, restrict access to opioids and other drugs. The evidence base was limited, and overall showed no major impacts in reducing harms and supporting medicinal use. However, studies of changes focused on increasing access to naloxone suggested the most promising evidence of effectiveness. More research and evaluation is required. With the risk of increased harms associated with opioid drug use in Australian, Canadian and United Kingdom settings, policymakers and other stakeholders need to prioritize measures that support: more research and evaluation; national campaigns publicising awareness of risks associated with opioid drug use and their appropriate medicinal use; and investment in health care services offering more appropriate clinical management of pain and opioid drugs.

Teacher imitation

Not 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.
