Development and validation of a new tool for assessment of trainees’ interventional musculoskeletal ultrasound skills
Authors' conclusion
We have developed and established validity evidence for a new interventional MSUS assessment tool.
Study context
- Population
- Physicians with different levels of interventional musculoskeletal ultrasound (MSUS) experience from 21 different countries130 videos for analysis
- Participants
- 65 physicians
- Outcome
- Validity evidence for the AIMUS tool
Methodological detailsblinded raters, video-recorded performances assessed in random order, rubber phantom simulation, Expert panel of rheumatologists modified an existing tool for invasive abdominal and thoracic US procedures; each physician performed two procedures on a rubber phantom, assessed by two blinded raters

Performance
As reported in the abstract
- Internal consistency (Cronbach's α), excellent
- 0.96
- Inter-case reliability (Pearson's correlation coefficient (PCC)), good
- 0.74
- Inter-rater reliability (PCC), moderate to good
- 0.58
- Discrimination between different levels of experience, highly significant
- P < 0.001
