Background/Purpose: The clinical decision-making process in pediatric arthritis lacks an objective, reliable bedside imaging tool. Musculoskeletal ultrasound (MSUS) is increasingly being utilized in children. In order to provide objective assessments of arthritis, reliable scoring systems are needed. Recently, a joint-specific scoring system for the assessment of arthritis of the pediatric elbow, wrist and finger joints were proposed[1]. These scoring systems have excellent reliability when used by experienced ultrasonographers ( >7 years of experience). This study aims to assess the reliability of a B-Mode and Power Doppler (PD) scoring system for arthritis in the pediatric elbow, wrist and finger when used by sonographers with different levels of expertise.

Methods: As part of the Childhood Arthritis and Rheumatology Research Alliance (CARRA) MSUS workgroup, a 2-hour training session and calibration exercise for each target joint was completed. Subsequently, B-mode and PD scoring exercises of still-images for each targeted joint were performed. Agreement between raters was determined using two-way single score intra-class correlation coefficients (ICC).

Results: 17 pediatric rheumatologists with different levels of ultrasound expertise (1 – 15 years) completed a 2-hour training session and calibration exercise for each targeted joint. Table 1 shows the inter-rater reliability obtained after the scoring exercise was completed for each joint. In general, there was excellent agreement for all B-mode views of the elbow, wrist, and finger joints. The reliability for PD views was excellent for the elbow and finger but was good for the dorsal ulnar recess and tendon views.

Conclusion: This effort identified the need for further training in PD settings and its scoring system(s). A training exercise and calibration exercise addressing the identified needs is ongoing. A novel BM and PD scoring systems for assessing arthritis of the pediatric elbow, wrist and finger joints were shown to have excellent reliability among pediatric MSUS sonographers with different levels of expertise. This reliable joint-specific scoring system for pediatric arthritis could serve as a clinical tool and outcome measure for scientific purposes with further refinement and validation.
