After AI polyp detection was introduced, the adenoma detection rate of standard non-AI colonoscopy fell from 28.4% to 22.4%.
Four Polish centres in the ACCEPT trial introduced AI polyp detection at the end of 2021 and then randomised colonoscopies to AI or no AI by examination date. Budzyń and colleagues compared 795 non-AI colonoscopies in the three months before AI with 648 non-AI colonoscopies in the three months after (September 2021 to March 2022). The adenoma detection rate fell from 28.4% to 22.4%, an absolute difference of -6.0 percentage points (95% CI -10.5 to -1.6), and exposure to AI was independently associated with lower detection (odds ratio 0.69). The study is observational and retrospective; the authors say continuous AI exposure 'might' reduce unaided performance.[1]
No individual harm documented; lower adenoma detection is a recognised quality marker associated with interval cancer risk (not measured in this study).
