Impact of Availability of Computer-Aided Detection Devices on Adenoma Detection During Colonoscopy: A Cluster Randomized Study.

CADe device availability at 42 Veterans Health Administration facilities increased colonoscopy adenoma detection rate from 50.7% to 54.9% (absolute +4.2 percentage points).

• Why it matters: Endoscopists’ ADR is linked to patients’ postcolonoscopy colorectal cancer death risk, yet real-world studies have often failed to show CADe benefits.
• What they did: In a pragmatic cluster randomized quality improvement study (Oct 2022–Feb 2023), facilities were equipped with CADe or assigned a control deployment date, and mixed-effects logistic regression assessed outcomes.
• The result: Postdeployment CADe sites showed ADR rising (+4.2 points) versus control sites where ADR fell (-0.7 points), and CADe availability increased adenoma detection odds (OR 1.22; 95% CI, 1.15–1.28).
