Analysis of the Effect of Pre-course Videos on Improving Clinical Skills in Emergency Ultrasound Training

Project Background Point-of-Care Ultrasound (POCUS) has become an important part of medical education in recent years. However, due to limited resources of ultrasound machines and clinical instructors, hands-on practice opportunities are limited, affecting the quality of teaching. Effectively imparting ultrasound operation skills has become a major challenge in improving training quality. This project aims to evaluate the impact of pre-class videos on enhancing ultrasound teaching effectiveness, particularly comparing videos shot with a first-person perspective (POV) to those shot with a face-to-face perspective. Project Objectives Primary Objective: To evaluate the impact of learning from pre-class videos on enhancing the effectiveness of ultrasound teaching. Secondary Objective: To investigate the effect of different filming techniques (POV versus face-to-face) on learning outcomes. Research Design The study will adopt a parallel research design, with subjects randomly assigned to one of three groups: the first-person perspective video group, the face-to-face perspective video group, and the control group (who will not watch any videos). Procedure on the Day of Instruction Complete a basic information and learning experience questionnaire. Conduct a pre-test practical, recording the operation of the ultrasound. Provide one-on-one instruction, offering detailed operational guidance. Conduct a post-test practical, allowing students to independently perform ultrasound-guided central venous catheter insertion. Complete a post-test questionnaire. Expected Outcomes This study anticipates that learning through pre-class videos will effectively enhance students\' ultrasound operation skills and improve teaching quality. Teaching videos shot with a POV may provide a more realistic learning experience, thereby enhancing students\' learning outcomes. By comparing different filming techniques, this project will provide empirical data that can inform future ultrasound teaching methods, ultimately improving the overall effectiveness of medical education.
