A85 LIKELIHOOD OF ENDOSCOPY CANCELLATION BASED ON VANCOMYCIN-RESISTANT ENTEROCOCCI (VRE) COLONIZATION STATUS AND INFECTION CONTROL PRACTICES
Bibliographic record
Abstract
Abstract Background “Terminal cleaning” is a practice of rigorous cleaning of endoscopy suite following endoscopies for patients colonized with vancomycin-resistant enterocci (VRE) with the intention of reducing VRE transmission. Such practice entails double-wiping all surfaces including the floor with disinfectants before a non-VRE patient can use the endoscopy room. While intuitive, such time-consuming practice is not supported by evidence and may have unintended negative impact on patient access to timely endoscopic evaluation. Aims To determine whether terminal cleaning of endoscopy suite for VRE-colonized patients has any negative impact on inpatient access to timely endoscopic evaluation. Methods As part of a quality improvement study, inpatient endoscopy data was gathered over a 3-month period between February 2021 and April 2021 at a tertiary centre. EUS, ERCP, and travel cases outside of the endoscopy suite were excluded. The cancellation rates were compared between VRE-colonized patients and non-VRE patients using the Fisher’s exact test. P value of <0.05 was considered statistically significant. Results A total of 262 inpatient endoscopic procedures were scheduled and included in the study. Sixty-six (25.2%) of inpatient procedures were cancelled during this period (Table 1). A total of 24 procedures were scheduled for VRE patients, 9 of which were cancelled because of insufficient operating time and two due to concurrent carbapenamase-producing organism carriage and poor bowel preparation. In the non-VRE group, 55 (23.3%) procedures were cancelled for various reasons (Table 1). In subgroup analysis where cancellations related to COVID-19 (n=14) were omitted, VRE patients had a significantly higher rate of procedure cancellations compared to non-VRE patients (42.3% vs. 18.5%; p<0.01). Conclusions The overall endoscopy cancellation rate for VRE-colonized patients was higher than those who were non-VRE-colonized. We propose that this is likely secondary to the delays from unnecessary terminal cleans imposed for VRE-colonized patients and await for post-intervention data. Funding Agencies None

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.
