Interrater reliability of subacromial ultrasound measures in the hands of novice sonographers.
Introduction: Ultrasound measures of subacromial structures are reliable in the hands of experienced sonographers, but it remains unknown if inexperienced clinicians can achieve a satisfactory level of interrater reliability. The aim was to investigate if standardised subacromial ultrasound measures are reliable in the hands of novice sonographers.
Methods: Two novice sonographers performed standardised ultrasound measures on patients diagnosed with subacromial pain syndrome and asymptomatic shoulders. The measures were: supraspinatus tendon thickness (SUPRA), subacromial bursa thickness (SASD), acromio-humeral distance (AHD) and dynamic impingement (DI). Reliability and agreement were evaluated by intraclass correlation coefficient (ICC (2.1)), standard error of measurement, minimal detectable change, 95% limits of agreement, Bland-Altman plots and Cohen's unweighted κ.
Results: Twenty-eight patients were recruited (28 symptomatic and 20 asymptomatic shoulders). The ICC of SUPRA ranged from 0.73 to 0.77. The ICC of SASD ranged from 0.41 to 0.88 and AHD from 0.68 to 0.72. Cohen's κ of DI in symptomatic shoulders was 0.29.
Conclusion: The interrater reliability of novice sonographers was found to be moderate to good when assessing SUPRA and AHD. For SASD and DI, the reliability ranged from poor to good. No significant differences in SUPRA and SASD thickness were found between symptomatic and asymptomatic shoulders.
期刊介绍：
The Danish Medical Journal (DMJ) is a general medical journal. The journal publish original research in English – conducted in or in relation to the Danish health-care system. When writing for the Danish Medical Journal please remember target audience which is the general reader. This means that the research area should be relevant to many readers and the paper should be presented in a way that most readers will understand the content.
DMJ will publish the following articles:
• Original articles
• Protocol articles from large randomized clinical trials
• Systematic reviews and meta-analyses
• PhD theses from Danish faculties of health sciences
• DMSc theses from Danish faculties of health sciences.
