Abstract |
Background |
EUS has less than optimal interobserver agreement for the diagnosis of chronic pancreatitis. The newly developed Rosemont consensus scoring system includes weighted criteria and stricter definitions for individual features.
Objective |
The primary aim was to compare the interobserver agreement of standard and Rosemont scoring.
Setting |
Multiple tertiary-care institutions.
Intervention |
Fifty EUS videos were interpreted by 14 experts. Each expert interpreted the videos on two occasions: First, the videos were read by using standard scoring (9 criteria). Second, after viewing a presentation of the Rosemont classification, the same experts re-read the videos by using Rosemont scoring.
Main Outcome Measurements |
Fleiss’ kappa (K) statistics are reported with 95% confidence intervals (CI).
Results |
The interobserver agreement was “substantial” (K = 0.65 [95% CI, 0.52-0.77]) for Rosemont scoring and “moderate” (K = 0.54 [95% CI, 0.44-0.66]) for standard scoring; however, the difference was not statistically significant (P = 0.12).
Limitations |
The sample size does not allow detection of differences in K of <0.25.
Conclusion |
Use of the Rosemont classification did not significantly increase interobserver agreement for EUS diagnosis of chronic pancreatitis compared with standard scoring.
