OD02 Developing Components For A National Strategy For Heart Valve Disease In Canada
Bibliographic record
Abstract
Introduction The research included a rapid review of current literature to describe epidemiology, management, and system impact of heart valve disease (HVD) in adult populations. Key issues were identified in consultation with expert focus groups and were framed across the continuum of care and systemic policy issues. The groupings were adapted and adjusted during deliberations. Methods A rapid literature review was conducted on HVD key interventions and evidence of effectiveness along with expert interviews to identify high-level themes for reform. This served as the evidentiary backgrounder. Two virtual policy engagements with clinical leaders, patients, and health system managers were conducted. The focus was their collective drafting of recommendations. These workshops identified nine thematic areas and developed associated recommendations for action under each theme. The success of the process is evident as the report has been taken up as a roadmap for ongoing research and policy work. Results A comprehensive grouping of recommendations for improving HVD detection, management, and treatment in Canada was produced. It was designed to be comprehensive to then allow more targeted work to proceed under an evidence-informed and clinically endorsed agenda. Conclusions Heart valve conditions are increasingly treatable, especially if detected early. Innovation in treatments as well as detection and management to address gaps in care were identified as the most urgent priorities. The key result was formation of formal working groups with a professional society to explore spoke–hub-and node models for care delivery and to launch awareness programs for early detection.

Full frame machine prediction
Teacher imitationNot 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.
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 source (direct Gemma or distilled Codex), not a consensus.
