Point-of-care ultrasound (POCUS) training courses effectively improve knowledge and skills, but little is known about their long-term impact on clinical practice. This prospective study evaluated the use of POCUS among 112 physicians who attended standardized training courses in Japan from 2017 to 2019. Participants were surveyed an average of 50 months post-course to assess changes in the frequency of POCUS use and identify barriers and facilitators. Results showed a significant increase in weekly POCUS use across all organ systems, with cardiac (61%), lung (53%), vascular (44%), and abdominal (50%) applications seeing notable growth. Facilitators included easy access to ultrasound machines (63%), departmental support (46%), and peer collaboration for skill development (47%). Barriers included lack of training opportunities (47%), limited access to machines (38%), and insufficient time for practice (33%).
Physicians who reported increased POCUS usage highlighted enhanced knowledge, improved imaging skills, and greater confidence as key factors. In contrast, those who did not increase usage cited low confidence, lack of supervising physicians, and limited training opportunities. These findings emphasize the importance of a supportive clinical environment, including peer mentorship and access to local experts, to sustain POCUS practice. Additionally, improving access to ultrasound equipment and providing ongoing educational opportunities are crucial for fostering POCUS integration into routine medical care.
The study underscores the need to address systemic barriers and create a culture that supports continued POCUS usage to maximize its potential benefits. With appropriate resources and training, POCUS can be a powerful tool to enhance diagnostic accuracy and patient care in diverse clinical settings.
