Online Ultrasound Curriculum on Learning Outcomes of Post-graduate Physicians

Current point-of-care ultrasound education faces multiple challenges. Traditional teaching methods, such as didactic lectures and bedside one-on-one training, are constrained by time, clinical workload, and faculty availability, leading to inconsistent learning outcomes. Additionally, PGY physicians, due to their limited clinical experience, struggle to develop proficiency in ultrasound in a randomized learning environment. The quality of ultrasound image acquisition and diagnostic accuracy is also highly dependent on the operator's experience. In recent years, online learning platforms, such as the Training Management System, have been introduced to enhance learning flexibility. However, the long-term impact of such platforms on trainees' clinical application remains unclear. This study aims to evaluate the impact of the TMS ultrasound curriculum on the learning outcomes of PGY emergency physicians and explore the feasibility of a blended learning approach in improving ultrasound skill application. This single-center retrospective study analyzes test data from PGY trainees who participated in emergency PoCUS training between 2018 and 2025, including post-course test scores, objective structured clinical examination scores, and self-reported TMS course participation. The findings of this study may provide insights into the effectiveness of online and blended learning models in developing ultrasound proficiency among junior physicians and inform future medical education curriculum design.
