Reliability of the Pediatric Specific Musculoskeletal Ultrasound Scoring Systems for the Elbow, Wrist, and Finger Joints
Authors' conclusion
The preliminary CARRA MSUS scoring systems for assessing arthritis of the pediatric elbow, wrist, and finger joints demonstrate excellent reliability among pediatric MSUS sonographers with different levels of expertise.
Study context
- Population
- Pediatric rheumatologists of the Childhood Arthritis and Rheumatology Research Alliance (CARRA) musculoskeletal ultrasound (MSUS) workgroup with different levels of MSUS expertise (1–15 yrs), scoring B mode and power Doppler (PD) mode still images of pediatric elbow, wrist and finger joints
- Participants
- 17 pediatric rheumatologists
- Outcome
- Interreader reliability of CARRA MSUS scoring systems (ICC for synovitis; Cohen kappa for tenosynovitis)
Methodological detailsinterreader reliability, 2-way single-score intraclass correlation coefficients (ICCs), Cohen kappa for tenosynovitis, still-image scoring exercises, 2-hour training session and calibration exercise for each joint
- Interreader reliability
- 2-way single-score ICCs
- Cohen kappa for tenosynovitis
- Still-image scoring exercises
- 2-hour training session and calibration exercise for each joint
Main finding
As reported in the abstract
Interreader reliability
Excellent reliability after first scoring exercise for all finger and elbow views on B mode and PD mode, and all wrist views on B mode
ICC > 0.75
