Bourbeau J, Julien M, Maltais F, et al. Reduction of hospital utilization in patients with chronic obstructive pulmonary disease: a disease-specific self-management intervention. Arch Intern Med2003 ; 163 : 585 –91 [OpenUrl][1][CrossRef][2][PubMed][3][Web of Science][4] QUESTION: In patients with chronic obstructive pulmonary disease (COPD), does a COPD specific self management programme reduce hospital use and improve health status more than usual care? Randomised (allocation concealed), blinded {data collectors and data analysts}*, controlled trial with 12 months of follow up. 7 hospitals in 3 cities in Quebec, Canada. 191 patients ≥50 years of age (mean age 70 y, 55% men) who had stable COPD (respiratory symptoms and medication unchanged for ≥4 wks); were current or previous smokers; had an FEV1 25–70% of predicted and an FEV1 forced vital capacity ratio <70%; no previous asthma, left congestive heart failure, terminal disease, dementia, or uncontrolled psychiatric illness; had not been in a respiratory rehabilitation programme in the … [1]: {openurl}?query=rft.jtitle%253DArchives%2Bof%2BInternal%2BMedicine%26rft.stitle%253DArch%2BIntern%2BMed%26rft.aulast%253DBourbeau%26rft.auinit1%253DJ.%26rft.volume%253D163%26rft.issue%253D5%26rft.spage%253D585%26rft.epage%253D591%26rft.atitle%253DReduction%2Bof%2BHospital%2BUtilization%2Bin%2BPatients%2BWith%2BChronic%2BObstructive%2BPulmonary%2BDisease%253A%2BA%2BDisease-Specific%2BSelf-management%2BIntervention%26rft_id%253Dinfo%253Adoi%252F10.1001%252Farchinte.163.5.585%26rft_id%253Dinfo%253Apmid%252F12622605%26rft.genre%253Darticle%26rft_val_fmt%253Dinfo%253Aofi%252Ffmt%253Akev%253Amtx%253Ajournal%26ctx_ver%253DZ39.88-2004%26url_ver%253DZ39.88-2004%26url_ctx_fmt%253Dinfo%253Aofi%252Ffmt%253Akev%253Amtx%253Actx [2]: /lookup/external-ref?access_num=10.1001/archinte.163.5.585&link_type=DOI [3]: /lookup/external-ref?access_num=12622605&link_type=MED&atom=%2Febnurs%2F6%2F4%2F111.atom [4]: /lookup/external-ref?access_num=000181561000009&link_type=ISI

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.
