Less Than Ideal: How Oncologists Practice With Limited Drug Access
Bibliographic record
Abstract
PURPOSE: To evaluate Canadian medical oncologists' perspectives on how barriers to accessing new expensive cancer drugs have affected their practice and their opinions on the drug approval and funding processes. METHODS: Canadian medical oncologists treating colorectal cancer (CRC) were surveyed by means of a self-administered, cross-sectional survey. RESULTS: Of the 164 eligible oncologists, there were 68 respondents (41.4% response rate). Only 29.4% of physicians felt they had been using the ideal first-line chemotherapy regimen for patients with metastatic CRC. Although all considered bevacizumab to be a component of the ideal first-line regimen, only 18% could use bevacizumab routinely, and less than half (44.8%) always discussed its role with their patients. In terms of accessing unfunded drugs, most physicians agreed that private payment should be allowed for drugs to be delivered at their own centers (76.1%) or private infusion clinics (52.2%). Ninety-seven percent of physicians reported major concerns about the drug approval and funding processes, and 85% of physicians supported the establishment of a national drug formulary. CONCLUSIONS: Canadian medical oncologists are struggling to provide optimal cancer care for their patients with metastatic CRC as a result of nonuniform access to preferred therapeutic drugs. In face of these challenges, physicians have had to use clinical trials and private infusion clinics and, at times, may avoid discussing drugs with limited access. Many oncologists are dissatisfied with the existing funding mechanism and approval processes and support private payment for unfunded drugs.

How this classification was reachedexpand
Full frame distilled prediction
Teacher imitationNot 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.
score_only:v0-immature-baseline · verbatim from the scoring run: score_only means the number may rank works, and no category label ships from itClassification
machine, unvalidatedMachine predicted; a candidate call from one teacher head, not a consensus.
