Tele-education in point-of-care ultrasound training

Area of Science:

• Medical Education
• Ultrasound Technology
• Distance Learning

Background:

• Traditional one-on-one ultrasound training faces scheduling and cost barriers.
• Developing effective remote training models is crucial for broader accessibility.
• Point-of-care ultrasound (POCUS) skills require hands-on practice and expert guidance.

Purpose of the Study:

• To develop and evaluate a tele-education model for POCUS training.
• To compare the effectiveness of tele-education against conventional and self-directed learning.
• To assess the impact of tele-education on learners' perceived workload.

Main Methods:

• A three-arm randomized trial comparing tele-education (TE), conventional education (CE), and self-directed learning (SL).
• TE involved remote instructors guiding learners via webcam, speakerphone, and real-time ultrasound image streaming.
• Skill tests and NASA-TLX surveys measured competency and workload post-intervention.

Main Results:

• Tele-education (median score 22) and conventional education (median score 24) were significantly more effective than self-directed learning (median score 16).
• No significant difference in skill scores was found between tele-education and conventional education (p=0.56).
• Perceived workload (NASA-TLX scores) was not significantly different across the three groups.

Conclusions:

• Tele-education is a viable and effective alternative to conventional ultrasound training.
• The model successfully bridges the gap created by traditional training limitations.
• Further adoption of tele-education can enhance POCUS skill dissemination globally.
