The role of endoscopy and findings in COVID-19 patients, an early North American Cohort
Bibliographic record
Abstract
BACKGROUND AND AIMS: Gastrointestinal manifestations in patients with COVID-19 are common but the role of endoscopy in this patient population remains unclear. We investigated the need for endoscopic procedures, their findings, and impact on patient care in a systematic and geographically diverse sample of patients hospitalized with COVID-19. METHODS: As part of the North American Alliance for the Study of Digestive Manifestations of COVID-19, we identified consecutive patients hospitalized with COVID-19 at 36 medical centers in the USA and Canada. We performed a secondary analysis of patients who underwent endoscopy, collecting information on endoscopic indications, findings, interventions, staffing, procedure location, anesthesia utilization, and adverse events. RESULTS: Data were collected on 1992 patients; 24 (1.2%) underwent 27 endoscopic procedures (18 upper endoscopies, 7 colonoscopies, 2 endoscopic retrograde cholangiopancreatographies). The most common indications were: gastrointestinal bleeding (13) and enteral access (6). The most common findings were erosive or inflammatory changes. Ten patients underwent an endoscopic intervention for hemostatic therapy (2), enteral access (6), or biliary obstruction (2). Half of cases employed anesthesiology support; no sedation-related adverse events were reported. One-third of cases were performed in the intensive care setting and one quarter in the endoscopy unit. CONCLUSIONS: In this large, systematic, geographically diverse cohort of patients hospitalized with COVID-19 in North America, very few patients underwent endoscopy despite a high prevalence of gastrointestinal manifestations. Almost all endoscopic findings and interventions were thought related to critical illness rather than direct viral injury. This systematic assessment of endoscopic necessity and outcomes may help guide resource allocation in the event of ongoing and future surges.

How this classification was reachedexpand
Full frame distilled prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. Learned from the 10,348 direct Codex labels and 10,348 direct Gemma labels. Candidate is the union of thresholded teacher heads; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels or direct frontier model 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 teacher head, not a consensus.
