In an observational study at four Polish centres, experienced endoscopists’ adenoma detection in colonoscopies done without AI fell from 28.4% to 22.4% in the three months after an AI detection system was introduced; the study is observational, and its authors list differences between the cohorts and a near doubling of colonoscopy volume after AI was introduced among its limitations.

Claim LD04-SL-C14 (v1.0)

Research opportunities this claim motivates

What this claim leaves open for research. Each is a hypothesis about a gap, not a finding.

Is the time AI saves paid for with weaker checking?The one observational case where workload and skill are confounded. Experienced endoscopists' unaided detection fell after a detection aid (not a time-saving tool) was introduced; the authors list a near doubling of volume among the limitations, and the claim does not license causal deskilling.
Do experienced clinicians lose unaided skill after routine AI use?Experienced endoscopists' detection in non-AI colonoscopies fell from 28.4% to 22.4% after AI was introduced, in an observational before-and-after study whose authors list cohort differences and a near doubling of volume among its limitations.

Provenance and status

Claim type: Estimate
Publication status: Eligible for publication, with qualifiers: strong scope
Verification state: Checked against the primary source. Who checked this claim is not recorded for it; claim checks so far were AI-led, and no person has checked claims against their sources.
Does not license: Causal deskilling; claims about generative AI; claims about trainees
Limitations: Observational; cohorts may differ; no blinding or withdrawal-time data; post-AI volume nearly doubled after Poland suspended screening; regression to the mean possible in high-baseline centres; read from the authors’ accepted manuscript, which may differ from the published version
