Facilitating Virtual Reality Integration in Medical Education: A Case Study of Acceptability and Learning Impact in Childbirth Delivery Training

Paper Information

• Subject Area: Integration of Virtual Reality Technology in Medical Education
• Keywords: Medical Education, Virtual Reality, User Experience Design, Childbirth Training, Obstetrics, Learning Outcomes, User Acceptability, Simulation Training, Experimental Study

Research Background and Issues

• Identified Problems or Challenges:

  • Medical students have limited opportunities to gain hands-on experience in delivery rooms, primarily due to factors such as patient acceptance, gender bias, and reluctance from physicians to involve students.
  • Traditional simulation training (e.g., using low/high-fidelity models), though effective, faces challenges such as high costs, time demands, operational complexity, and resource scarcity.
  • The potential of virtual reality technology in medical education remains underexplored, and its acceptability and feasibility for integration into mainstream curricula are uncertain.

• Research Motivation and Related Work:

  • Motivations include improving students' access to standardized delivery room experiences, increasing the availability of remote learning materials, and addressing teaching challenges during the pandemic.
  • Virtual reality is considered capable of providing immersive learning experiences, with multisensory interaction not only enhancing learning efficacy but also addressing spatial and resource limitations.

Solution

• Core Methods or Solutions:

  • Developed a virtual reality childbirth training simulator focused on the normal vaginal delivery process, simulating the second and third stages of labor and demonstrating the entire delivery process from start to finish.
  • Employed a detailed design process, including scenario standardization, storyboard creation, 3D modeling and animation, prototype development, and validation to ensure medical accuracy and alignment with learning objectives.

• Innovations:

  • Introduced a pair of virtual hands to guide users in performing precise hand movements and improve practical skills through real-time feedback in the virtual environment.
  • Adopted a mixed reality (MR) approach, combining real interactive tools to enhance user acceptability.
  • Integrated AI-driven chaotic scenarios into the simulator, making the training environment more akin to high-pressure, high-complexity real-world medical situations.

• Implementation Steps:

  • Defined delivery scenarios and learning content (including seven key steps of delivery and the use of related tools).
  • Created a step-by-step training process using visual representation, audio feedback, and motion capture.
  • Embedded multiple-choice questions and real-time explanations within the simulator to reinforce students' understanding of key learning concepts.

Research Outcomes

• Specific Results:

  • Large-scale study results showed a 24.9% improvement in knowledge scores among medical students using virtual reality technology.
  • Virtual reality training excelled in visualization and process coherence but received significantly lower self-reported feasibility scores compared to traditional model training.

• Advantages:

  • Demonstrated significant knowledge improvement compared to traditional simulation training.
  • Provided an immersive experience, allowing students to become more familiar with actual spatial layouts.

• Experiment or Evaluation Results:

  • Virtual reality scored significantly lower than traditional model training on five out of six feasibility indicators (including confidence, usability, feedback, engagement, and presence).
  • Student feedback indicated a preference for a mixed teaching model (VR combined with physical models) and highlighted issues such as the "lack of tactile feedback" and the "need for enhanced image quality."

• Limitations and Future Directions:

  • Limitations:

    • Did not evaluate long-term memory retention or psychomotor skill transfer.
    • Students' initial learning curve with the virtual reality system may impact confidence levels.
    • Resource constraints related to venue capacity and VR equipment deployment.

  • Future Directions:

    • Improve the naturalness and usability of the VR interaction system, including optimizing gesture design.
    • Develop more complex scenarios, such as shoulder dystocia simulations, to assess cognitive load and operational performance.
    • Integrate real-time feedback mechanisms and mixed reality to further enhance VR's visual and tactile effects.

Conclusion

This study proposed an obstetric childbirth simulator incorporating virtual reality technology and provided evidence through large-scale experiments supporting its effectiveness in improving learning outcomes. However, students' acceptability of the technology was relatively low, indicating challenges in integrating new technologies with traditional medical teaching models. The authors proposed several future improvement strategies, including teacher involvement, mixed learning models, and complex scenario simulations, to promote the acceptability and effectiveness of virtual reality in medical education.
