ABSTRACT
PURPOSE:
This study aimed to assess the validity of simulation-based assessment of ultrasound skills for thyroid ultrasound.METHODS:
The study collected validity evidence for simulation-based ultrasound assessment of thyroid ultrasound skills. Experts (n = 8) and novices (n = 21) completed a test containing two tasks and four cases on a virtual reality ultrasound simulator (U/S Mentor's Neck Ultrasound Module). Validity evidence was collected and structured according to Messick's validity framework. The assessments being evaluated included built-in simulator metrics and expert-based evaluations using the Objective Structured Assessment of Ultrasound Skills (OSAUS) scale.RESULTS:
Out of 64 built-in simulator metrics, 9 (14.1%) exhibited validity evidence. The internal consistency of these metrics was strong (Cronbach's α = 0.805) with high test-retest reliability (intraclass correlation coefficient = 0.911). Novices achieved an average score of 41.9% (SD = 24.3) of the maximum, contrasting with experts at 81.9% (SD = 16.7). Time comparisons indicated minor differences between experts (median 359 s) and novices (median 376.5 s). All OSAUS items differed significantly between the two groups. The correlation between correctly entered clinical findings and the OSAUS scores was 0.748 (p < 0.001). The correlation between correctly entered clinical findings and the metric scores was 0.801 (p < 0.001).CONCLUSION:
While simulation-based training is promising, only 14% of built-in simulator metrics could discriminate between novices and ultrasound experts. Already-established competency frameworks such as OSAUS provided strong validity evidence for the assessment of otorhinolaryngology ultrasound competence.Palavras-chave
