Abstract

fetched live from OpenAlex

OBJECTIVES: To assess process of care in nonvariceal upper gastrointestinal bleeding (NVUGIB) using a national cohort, and to identify predictors of adherence to 'best practice' standards. METHODS: Consecutive charts of patients hospitalized for acute upper gastrointestinal bleeding across 21 Canadian hospitals were reviewed. Data regarding initial presentation, endoscopic management and outcomes were collected. Results were compared with 'best practice' using established guidelines on NVUGIB. Adherence was quantified and independent predictors were evaluated using multivariable analysis. RESULTS: Overall, 2020 patients (89.4% NVUGIB, variceal in 10.6%) were included (mean [± SD] age 66.3±16.4 years; 38.4% female). Endoscopy was performed in 1612 patients: 1533 with NVUGIB had endoscopic lesions (63.1% ulcers; high-risk stigmata in 47.8%). Early endoscopy was performed in 65.6% and an assistant was present in 83.5%. Only 64.5% of patients with high-risk stigmata received endoscopic hemostasis; 9.8% of patients exhibiting low-risk stigmata also did. Intravenous proton pump inhibitor was administered after endoscopic hemostasis in 95.7%. Rebleeding and mortality rates were 10.5% and 9.4%, respectively. Multivariable analysis revealed that low American Society of Anesthesiologists score patients had fewer assistants present during endoscopy (OR 0.63 [95% CI 0.48 to 0.83), a hemoglobin level <70 g⁄L predicted inappropriate high-dose intravenous proton pump inhibitor use in patients with low-risk stigmata, and endoscopies performed during regular hours were associated with longer delays from presentation (OR 0.33 [95% CI 0.24 to 0.47]). CONCLUSION: There was variability between the process of care and 'best practice' in NVUGIB. Certain patient and situational characteristics may influence guideline adherence. Dissemination initiatives must identify and focus on such considerations to improve quality of care.

Not 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.
