A really good study, in my view, is one that provides useful data and 100% backs up what I want it to find.
N Yallanki et al JPGN 2023; 76: 295-299. Inter and Intraobserver Variation in Interpretation of Fecal Loading on Abdominal Radiographs
Methods: Electronic records of 100 children seen in the emergency room for gastrointestinal symptoms who had an abdominal radiograph performed were included. Four physicians from each specialty including gastroenterology, radiology, and emergency medicine interpreted the radiographs independently.
- Overall agreement among all providers: 40.8%. Fixed margin kappa 0.18
- Intradepartmental agreement: 41.5% for Peds GI, 36.7% for Peds EM, and 47.3% for Peds Radiology.
- The only surprising finding was the low intradepartmental agreement for Peds EM; many of my colleagues have insisted that all Peds EM think everyone has a high fecal burden (so there should have been uniform agreement)
