Transcript
A short narrated walkthrough of HAM, for accessibility and search.
HAM is an objective, reproducible assessment of endoscopic tip control. A trainee uses their unit's standard endoscope to track a stencil pattern transferred onto a piece of ham. The attempt is recorded and uploaded to ham-rater.gieqs.com.
The AI scores the attempt on four metrics: speed of the tip, stability across frames, time on line within the stencil, and total versus active duration. Each metric is z-scored against a reference cohort of experienced endoscopists, producing a percentile and a tier — trainee, competent, or expert.
Three peer-reviewed studies validate the method. Frontline Gastroenterology (Debels et al.) established validity against human raters in a clinical-grade task. HAM-2 (Endoscopy International Open, in press) demonstrated stratification across experience levels. HAM-AI (Endoscopy International Open, in press) showed AI scoring is comparable to human rating, enabling scale.
The platform is open at ham-rater.gieqs.com. A complete setup costs around €300.
