Evaluation of a Training Course for Simulating Head and Neck Ultrasound-Guided Core Needle Biopsy
Training Course for UG-CNB
Main Article Content
Abstract
Background: Ultrasound-guided core needle biopsy (US-CNB) is a preferred diagnostic tool for head and neck lesions. This study assessed the effectiveness of a hands-on US-CNB workshop in enhancing clinicians’ knowledge and skills.
Methods: Twenty-three clinicians attended a structured workshop with a two-hour theoretical session and two-hour practical training using an agar-agar phantom model. Knowledge was assessed via pre- and post-training multiple-choice questions. Confidence and skill improvement were surveyed, and linear regression analyzed factors affecting outcomes.
Results: Post-training scores improved significantly (mean increase: 9.83 to 16.87, p < 0.001). Older participants scored marginally higher (0.134 points/year, p = 0.022), but experience did not influence gains (p = 0.243). Most rated the workshop highly, particularly hands-on training, reporting greater confidence and technical skill.
Conclusion: Despite a small sample and phantom limitations, the workshop effectively enhanced US-CNB knowledge and proficiency. Structured hands-on training can improve clinician competency in this technique.
