Using virtual reality or slideshow to teach ultrasound-guided lumbar puncture: immersion increases fun

Area of Science:

• Medical Education
• Procedural Skills Training
• Virtual Reality Applications

Background:

• Ultrasound-guided lumbar puncture (USG LP) is a crucial medical procedure.
• VR has emerged as a promising tool for teaching procedural skills in medicine.
• Previous studies suggest USG LP can improve success rates without significantly increasing procedure time.

Purpose of the Study:

• To compare the effectiveness of virtual reality (VR) versus traditional slideshow lectures for teaching USG LP.
• To evaluate medical student engagement, enjoyment, and performance in learning USG LP through VR and slideshow modalities.

Main Methods:

• A VR lecture and a slideshow lecture were developed to teach USG LP.
• Medical students were randomized to receive training via either VR or slideshow.
• Participants completed a survey and were assessed on their performance using an LP task trainer.

Main Results:

• VR training was associated with higher ratings for fun, perceived effectiveness, and enjoyment, and lower boredom levels.
• No significant differences were observed in cerebrospinal fluid acquisition, checklist scores, or procedure duration between groups.
• VR participants reported more side effects and technical issues.

Conclusions:

• VR is perceived as a more engaging and enjoyable training method for USG LP compared to slideshows.
• While procedural outcomes were comparable, VR introduces a learning curve related to technology troubleshooting.
• VR holds potential for enhancing medical procedural training, but technical challenges need consideration.
