Computer Aided Detection (CADe) of Neoplasia during Colonoscopy - “GI Genius”
Description
The device improves endoscopy quality by aiding neoplastic lesion detection during procedures. Multiple studies and meta-analyses have found these devices increase adenoma detection rates (ADR), a well-established metric for colonoscopy quality that is related to colon cancer incidence and death. Randomized implementation of the devices across VHA facilities allowed for a pragmatic evaluation of the impact of these devices on ADR. The evaluation demonstrated that the provision of colonoscopy Computer Aided Detection devices resulted in a statistically significant 21% increase in the odds of adenoma detection and an absolute increase in ADR of approximately 4% compared to colonoscopy without CADe.
Detailed example
During endoscopy, the CADe device automatically detects, and highlights suspected neoplastic lesions / polyps in real time. A highlighted rectangle automatically surrounds suspected lesions. No results or data are tracked or automatically documented. The device physically connects to existing endoscopes, video processors, and display monitors, but does not connect to the VA network.
AI / analytics pattern
Computer Vision: AI that processes and interprets visual data (e.g., images and videos).
Automation level / stage
c) Deployed – The use case is being actively authorized or utilized to support the functions or mission of an agency.
Expected benefit
These devices demonstrably improve endoscopy quality within the VHA, which in turn improves outcomes for Veterans, ultimately reducing morbidity and mortality.
