Competency in Esophagogastroduodenoscopy: A Validated Tool for Assessment and Generalizable Benchmarks for Gastroenterology Fellows.

Nationally generalizable learning curves for EGD skills in GI fellows are described. Average ACE-E scores of 3.5, independent D2 intubation rates of 95%, and D2 intubation times of ≤4.75 minutes are recommended as minimum competency criteria. On average, it takes GI fellows only 150 procedures to simply drive the scope adequately but 250 procedures to achieve minimum competence in the remaining cognitive and motor skills. The D2 intubation rate threshold and learning curve found in this multicenter cohort using the ACE-E tool are similar to those recently described by researchers in the United Kingdom; however, development of cognitive and overall competence requires a higher procedure threshold than previously described.
