Canadian Credentialing Guidelines for Colonoscopy
Bibliographic record
Abstract
A series of credentialing guidelines for gastrointestinal endoscopic procedures performed in the management of adult patients has been developed by the Canadian Association of Gastroenterology (CAG) Endoscopy Committee, approved by the Clinical Affairs Committee, and reviewed and endorsed by the Executive Board.In the present article, the CAG suggests specific guidelines for credentialing colonoscopy.It is intended to be read in conjunction with the introductory article that outlines the principles of credentialing (1).The CAG does not credential individuals for colonoscopy; that is the responsibility of the endoscopist's local institution or facility.The purpose of these guidelines is to provide a framework that will allow organizations to assess the training and competence of applicants to perform colonoscopy as part of the credentialing process for the granting of privileges.Colonoscopy is performed to visualize the colonic mucosa, and can be both a diagnostic and therapeutic procedure; it requires the passage of a specialized endoscope -a colonoscope -via the anus or a colostomy to the cecum and, in some cases, to the terminal ileum.The purpose of the procedure is to document any abnormalities, to take biopsies and perform photographic documentation when appropriate, to remove polyps, or to perform therapy such as stricture dilation or hemostasis, if necessary, while minimizing procedure-related risks such as excessive sedation, cardiorespiratory compromise, bleeding and colonic perforation. COGNITIVE ASPECTS Appropriate indicationsKnowledge of appropriate contraindications and indications for colonoscopy, and the application of appropriate screening and surveillance intervals, is essential.Appropriate indications for colonoscopy, recommended by the American Society for Gastrointestinal Endoscopy (ASGE) and the U.S. Multi-Society Task Force on Colorectal Cancer, are shown in Table 1 (2).An indication should be documented for each procedure, and if it is a nonstandard indication, it should be justified in the documentation (3).Studies have shown that when colonoscopy is performed for appropriate reasons, significantly more clinically relevant diagnoses are made (4-6).However,

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.
