Posted a very early stage draft with rock star collaborators. Key question: when we actually roll out AI tools, how do people use them? Do they just defer completely? Does it improve productivity and ability? We look in the medical setting of pulmonary embolisms paulgp.com/papers/Radio...
We study how radiologists use AI to diagnose pulmonary embolism (PE), tracking over 100,000
scans interpreted by nearly 400 radiologists during the staggered rollout of an FDA-approved
diagnostic platform. When AI flags PE, radiologists agree 84% of the time; when AI predicts no PE,
they agree 97%. Disagreement evolves substantially: radiologists initially reject AI-positive PEs in
30% of cases, dropping to 12% by year two. Despite a 16% increase in scan volume, diagnostic speed
remains stable while per-radiologist monthly volumes nearly double, with no change in patient
mortality—suggesting AI improves workflow without compromising outcomes. We document
significant heterogeneity in AI collaboration: some radiologists reject AI-flagged PEs half the time
while others accept nearly always; female radiologists are 6 percentage points less likely to override AI
than male radiologists. Moderate AI engagement is associated with the highest agreement, whereas
both low and high engagement show more disagreement. Follow-up imaging reveals that when
radiologists override AI to diagnose PE, 54% of subsequent scans show both agreeing on no PE
within 30 days.
