The purpose of this study was to establish standards for musculoskeletal ultrasound competency through knowledge and skills testing using criterion-referenced methods.
Two groups of rheumatology fellows trained in musculoskeletal ultrasound through a standardized curriculum, which required submission of ultrasound studies for review over 8 months. Both groups then completed written and practical examinations in musculoskeletal ultrasound. Instructors, advanced users, and intermediate users of musculoskeletal ultrasound served as comparison groups. A passing score (competency) was established for the written examination by the Angoff procedure and for the practical examination by the borderline method.
Thirty-eight fellows (19 in each group) took the final examination. Five fellows failed the written examination, and 1 failed the practical examination, whereas none of the advanced users failed. Written examination scores did not differ between the two fellow groups (74% versus 70%; P > .05), were reliable, and were able to discriminate between the intermediate and advanced groups. Practical and written examination results correlated in both groups (first group, r = 0.70; P = .0008; second group, r = 0.59; P = .009).
Criterion-referenced methods were used for the first time to determine fellow musculoskeletal ultrasound competency. The examination used to determine competency was reproducible, was reliable, and could differentiate musculoskeletal ultrasound users with different levels of experience. Most rheumatology fellows completing our program passed the written and practical examinations, suggesting achievement of basic musculoskeletal ultrasound competency.
本研究旨在通过使用基于标准的知识和技能测试方法,为肌肉骨骼超声能力建立标准。
两组接受过肌肉骨骼超声标准化课程培训的风湿病研究员,该课程要求在 8 个月内提交超声研究进行审查。然后,两组均完成了肌肉骨骼超声的书面和实践考试。肌肉骨骼超声的讲师、高级用户和中级用户作为比较组。通过 Angoff 程序为书面考试和通过边界方法为实践考试确定及格分数(能力)。
38 名研究员(每组 19 名)参加了期末考试。有 5 名研究员未能通过书面考试,1 名未能通过实践考试,而没有高级用户不及格。两组研究员的书面考试成绩(74%对 70%;P>0.05)没有差异,具有可靠性,并能够区分中级和高级组。两组的实践和书面考试结果均相关(第一组 r=0.70;P=0.0008;第二组 r=0.59;P=0.009)。
首次使用基于标准的方法确定研究员的肌肉骨骼超声能力。用于确定能力的考试具有可重复性、可靠性,并且能够区分具有不同经验水平的肌肉骨骼超声使用者。完成我们计划的大多数风湿病研究员都通过了书面和实践考试,这表明他们已经达到了基本的肌肉骨骼超声能力。
