  curation (4.24 [0.58] vs 4.76 [0.48]), readability (4.00 [0.64] vs 4.64 [0.49]), correctness (4.52 
  
  [0.64] vs 4.90 [0.39]), and patient safety (4.06 [0.86] vs 4.50 [0.56]). 
  
  In extrapolating the estimated worst-case scenario impact of these performance gaps on 
  
  patient safety, the 3 expert clinicians determined none of the identified model performance issues 
  
  were anticipated to create a level 1 (life-threatening) safety event (see examples of worst case 
  
  scenarios in eTable 2 in Supplement 1). While the incompleteness and faulty logic identified in the 
  
  automated summaries received mean (SD) safety scores of 4.20 (0.93) and 4.60 (0.75), respectively; 
  
  13 (8.7%) and 11 (7.3%) of these events, respectively, were determined to have the potential to create 
  
  a level 2 patient safety event following EM-to-IP handoff, substantially higher compared with the 
  
  physician-written summaries (0%). All of the 5 hallucinations had patient safety scores between 4
