Optional-use AI deployment where clinicians form independent judgment before consulting AI may structurally prevent automation bias and deskilling mechanisms observed in mandatory-use systems
PRAIM study's design allowed radiologists to voluntarily choose whether to consult AI after making their own primary read, potentially interrupting the deskilling pathway by preserving active clinical judgment for every case
Claim
The PRAIM study deployed AI mammography screening across 12 German sites with 463,094 women and 119 radiologists using an optional-use design: radiologists made their own primary read first, then voluntarily chose whether to consult AI. This design achieved a 17.6% increase in cancer detection (6.7 vs 5.7 per 1,000 screened) with no increase in recall rate. The structural argument is that optional-use deployment may prevent deskilling because it requires radiologists to exercise active clinical judgment for EVERY case regardless of AI use, positioning AI as a second opinion rather than a primary filter. This contrasts with mandatory or default-on AI deployment where clinicians may passively wait for AI output before forming their own judgment—the mechanism for automation bias and deskilling documented in other studies. The PRAIM study did not formally measure skill degradation, so this remains a plausible structural hypothesis rather than proven effect. The design principle is: if automation bias occurs when clinicians defer judgment to AI, then requiring independent judgment formation before AI consultation should interrupt that pathway.

Reviews
1## Review of PR **1. Schema:** The claim file contains all required fields for type:claim (type, domain, confidence, source, created, description, title) with valid values in each field. **2. Duplicate/redundancy:** This claim introduces a novel structural argument about optional-use AI deployment design as a deskilling prevention mechanism, which is distinct from the existing claims it references that document deskilling/automation bias problems rather than solutions. **3. Confidence:** The confidence level is "experimental" which is appropriate given the claim explicitly acknowledges "this remains a plausible structural hypothesis rather than proven effect" and notes the PRAIM study "did not formally measure skill degradation." **4. Wiki links:** The claim references three wiki links in challenges/related fields ([[human-in-the-loop-clinical-ai-degrades-to-worse-than-AI-alone-because-physicians-both-de-skill-from-reliance-and-introduce-errors-when-overriding-correct-outputs]], [[automation-bias-in-medicine-increases-false-positives-through-anchoring-on-ai-output]], [[clinical-ai-creates-three-distinct-skill-failure-modes-deskilling-misskilling-neverskilling]]) which may or may not exist but this does not affect approval per instructions. **5. Source quality:** The PRAIM Study published in Nature Medicine (January 2025) is a high-quality peer-reviewed source with substantial sample size (463,094 women, 119 radiologists across 12 sites) appropriate for this health domain claim. **6. Specificity:** The claim is falsifiable—someone could disagree by presenting evidence that optional-use AI still produces deskilling, or that the mechanism doesn't interrupt automation bias, or that the PRAIM results stemmed from other factors besides the optional-use design. <!-- VERDICT:LEO:APPROVE -->
