Critical Appraisal of Clinical Practice Guidelines Targeting Chronic Obstructive Pulmonary Disease
Bibliographic record
Abstract
BACKGROUND: Chronic obstructive pulmonary disease (COPD) is so prevalent that the endorsement of management strategies by professional organizations issuing clinical practice guidelines (CPGs) will likely influence the clinical and financial resources allocated to this condition. OBJECTIVES: To examine the content of and to critically appraise the CPGs targeting COPD. METHODS: We identified, through a MEDLINE search (from January 1990 to May 1999) and contacts with experts and professional organizations, the CPGs for the overall management of COPD. We assessed the guidelines according to an index of quality measuring 3 dimensions: the rigor of development, the context and content, and the extent to which the dissemination and implementation have been addressed. The recommendations were also examined and compared. RESULTS: Of the 15 CPGs we included, none was based on a systematic review of the literature. Two were independently reviewed before their release, 1 included strategies for dissemination and implementation, and 1 estimated the economic implications associated with its recommendations. The recommendations were often difficult to interpret (reviewers' agreement: kappa median, 0.41). When unanimity existed regarding the benefits of a given management modality (such as respiratory rehabilitation), discrepancies were often identified in the application of the recommendation. CONCLUSIONS: The methodological quality of CPGs targeting COPD is limited, and there are disparities among many of their recommendations. Despite there being several CPGs worldwide, there is a need for an evidence-based summary of the literature to serve as a resource for those who provide health care to individuals with COPD.

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; the direct Gemma label and the distilled Codex classifier agree on what is shown here.
