Abstract

fetched live from OpenAlex

Background. Chronic hepatitis C (HCV) is a significant cause of morbidity in Ontario. In 1996-1997, the only treatment available was interferon, an expensive, inefficacious therapy with significant side effects. Publicly funded interferon therapy was available through an individualized process requiring review of applications by expert hepatologists. Results. Reviewers approved 83% of 370 applicants during the study period. Kappa statistic for agreement with guidelines was 0.225. Only 22% of approved patients appeared to complete therapy. 56% of drug costs were paid for incomplete therapy. Conclusions. Reviewers adopt an overly permissive stance toward approval of interferon for HCV patients. Research questions. Do reviewers' approvals of therapy agree with clinical practice guidelines in effect during 1996-1997? What proportion of approved patients finishes prescribed therapy? What are the costs associated with successful and unsuccessful therapy?Methods. Descriptive analysis of clinical and administrative databases of the Ontario Drug Benefit Program.

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.
