Four participant ED sonologist-physicians were trained on the first set of 25 videos showing normal appendix or normal bowel in patients without appendicitis to note if normal appendix was seen in any part or in it\u2019s entirety from tip-to-cecum. They were then tested on the second set of similar videos. A third set of 25 videos from patients who had appendicitis where participant sonologists were asked to note if appendicitis was present or absent, with and without appendicolith or perforation. Cohen\u2019s Kappa was calculated in aggregate and stratified by experience vs. novice against a senior sonologist-physician aware of all patient outcomes for visualization of: 1. any part of normal appendix, 2. normal appendix visualized from tip to cecum 3. any part of appendicitis, 4. appendicolith, 5. appendiceal perforation.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Results<\/jats:title>\n                    <jats:p>Cohen\u2019s Kappa for any part of normal appendix, 0.71, 95% CI (0.58\u20130.85); normal appendix tip-to-cecum, 0.43, 95% CI (0.19\u20130.67), appendicitis, 0.53, 95%CI (0.34\u20130.70), appendicolith, 0.63, 95%CI (0.43\u20130.84), perforated appendicitis, 0.46, 95%CI (0.22\u20130.70).
