Background:
Virtual reality (VR) simulations provide immersive, interactive learning environments that can support clinical skill development in medical education. However, evidence for its application in Korean medical education remains limited. This pilot study aimed to develop and evaluate HaniE-VR1, a 360° VR simulation program designed to teach ultrasound-guided pharmacopuncture.
Methods:
A one-group pre-post experimental design was used with 60 undergraduate students from the College of Korean Medicine (pre-intervention n = 60; post-intervention n = 59, due to one missing post-survey response). The primary outcomes were changes in self-efficacy (MASS) and ultrasound skill-related performance (OSAUS). Secondary outcomes included VR awareness, usability, satisfaction, presence, and cognitive load. Participants completed a VR-based training session using a Meta Quest 3 headset. Effect sizes (Cohen's d) were calculated for pre-post comparisons. Statistical significance was set at p < 0.05.
Results:
Post-intervention findings showed significant improvements in self-efficacy (MASS: 3.21 ± 0.51 to 3.54 ± 0.61, p < 0.001, d = 0.66) and ultrasound skill performance (OSAUS: 2.66 ± 0.73 to 3.54 ± 0.71, p < 0.001, d = 1.16). VR awareness also improved significantly (4.33 ± 0.66 to 4.76 ± 0.56, p < 0.001, d = 0.65). Participants reported acceptable usability (SUS = 69.49) and high satisfaction (4.51 ± 0.56), confidence (4.32 ± 0.53), and presence (4.40 ± 0.65). Cognitive load and simulator sickness were minimal.
Conclusions:
The HaniE-VR1 program was associated with improvements in perceived clinical competence, self-efficacy, and learning satisfaction, demonstrating acceptable usability and preliminary educational potential. VR simulations represent a feasible, safe, and engaging approach for integrating experiential learning into Korean medical curricula. Given the exploratory nature of this pilot study, findings should be interpreted with caution, and future controlled research is warranted.
