Validation of an educational simulation model for vaginal hysterectomy training: a pilot study

Area of Science:

• Surgical Simulation
• Gynecologic Surgery Education
• Medical Device Validation

Background:

• Realistic simulation models are crucial for surgical training.
• The Miya Model was developed for vaginal surgery simulation.
• Assessing the validity and reliability of new surgical simulators is essential.

Purpose of the Study:

• To describe the Miya Model for vaginal hysterectomy simulation.
• To present pilot data on the model's validity and reliability.
• To evaluate the Miya Model as an assessment tool for vaginal hysterectomy skills.

Main Methods:

• Ten novice residents and ten expert gynecologists performed vaginal hysterectomy on the Miya Model.
• Procedure time and blood loss were recorded.
• Participants completed a post-simulation survey; expert surgeons used OSATS and VSSI for video-based skill assessment.

Main Results:

• The Miya Model was rated effective or highly effective by 80% of novices and 100% of experts.
• Novices had significantly longer procedure times; blood loss did not differ between groups.
• High interrater reliability (0.77-0.93) was observed for OSATS and VSSI scores.

Conclusions:

• The Miya Model shows promise as a training and assessment tool for vaginal surgery.
• Further studies are needed to fully establish its utility in surgical education.
• The model's effectiveness is supported by participant feedback and objective skill assessments.
