Not all colonoscopies are the same: New AI audits them at scale

THE AI ANGLE
Auditing colonoscopy quality metrics from procedural video at scale

Northwestern Medicine researchers validated an AI tool that automatically evaluates colonoscopy quality at scale by reviewing procedural video footage across nearly 18,600 cases. The system accurately tracks key indicators that are impractical for humans to measure systematically—including withdrawal time, polyp removal numbers, and adherence to recommended polypectomy techniques. This capability addresses significant variations in colonoscopy quality and helps health systems feasibly operationalize routine audits linked to reduced colorectal cancer mortality.

THE TEACHING ANGLE
Faculty can explore the pedagogical and operational tension between using retrospective AI audits to expose clinician blind spots versus real-time AI tools that risk clinical deskilling.
