Summary

AI-generated

This guideline from the ASGE proposes 9 quality measures designed to improve the design, conduct, and reporting of endoscopic research [1]. Developed by a joint task force via group consensus and systematic literature searches [2], it establishes a framework covering sample size calculation, patient selection, outcome definitions, data integrity, blinding, trial oversight, equity, and conflict disclosures [1, 2, 6, 8].

Key Takeaways

1
High-quality clinical investigation in endoscopy requires rigorous methodology and transparent reporting.
2
The ASGE Quality Assurance in Endoscopy and Research Committees established these 9 quality measures to provide a practical, structured framework.
3
While not all measures are evidence-based, they rely on expert opinion, logic, and consensus to optimize research design and integrity.
4
Applying an equity lens across the entire research continuum (study choice, patient selection, and AI algorithm development) is highly encouraged to produce fair and generalizable results.

What's New in This Version

This document represents the first version (v1) of these quality measures, prioritizing indicators judged to be reasonably practical and achievable. Content is expected to evolve in future versions based on feedback from endoscopic investigators and a changing evidence base.
