Standardization of interstitial lung disease assessment by ultrasound: results from a Delphi process and web-reliability exercise by the OMERACT ultrasound working group
Authors' conclusion
Consensus-based ultrasound definitions for B-lines and pleural line irregularity were obtained, with moderate to good reliability to detect these lesions using video-clips.
Study context
- Population
- 23 experts in sonography, OMERACT Ultrasound Working Group; ultrasound-detected interstitial lung disease (ILD) findings in rheumatic and musculoskeletal diseases (RMDs)
- Participants
- 80 video-clips
- Outcome
- Consensus-based definitions for ultrasound-detected ILD findings in RMDs and their reliability in dynamic images
Methodological detailsthree Delphi rounds, kappa statistics, video-clips
- Three Delphi rounds
- Kappa statistics
- Video-clips
