Funding Information:
This study is funded by The Eunice Kennedy Shriver National Institute of Child Health and Human Development, National Institutes of Health, grant number: 1R43HD084151-01. We would like to thank all of our 3rd-year medical students at the Wake Forest School of Medicine who volunteered their time as surgical assistants: Lucy Lan, Shannon Mentock, Mathew Fore, Breona Barr, Porvi Chbabra, Jennifer Udom, David Crouse, Sophia Wang, Barclay Mcghee, Vanessa Ng, James Kaan, Joshua Pan, Jia Hao Liang, and Jacob Blackwell. We also greatly appreciate our videographers: head videographer John Beasley; volunteers: Mitchell Avent, Devin Williams, Bree Hollowell, Ryan Miyazaki, and Katherine Bowman.

N2 - Introduction and hypothesis: The Miya Model ™ (Miyazaki Enterprises, Winston-Salem, NC, USA) was designed as a realistic vaginal surgery simulation model. Our aim was to describe this model and present pilot data on validity and reliability of the model as an assessment tool of vaginal hysterectomy skills. Methods: We video recorded ten obstetrics and gynecology residents (novice group) and ten practicing gynecologists (expert group) performing vaginal hysterectomy using the Miya model. Blood loss and time taken to complete the procedure were documented. Participants evaluated the model using a postsimulation survey. In addition, two experienced gynecologic surgeons independently evaluated video recordings of each participant’s performance using two previously validated global rating scales: Reznick’s Objective Structured Assessment of Technical Skill (OSATS) and Vaginal Surgical Skills Index (VSSI). Results: Most participants (80% of novice and 100% of expert group) rated the model as effective or highly effective for vaginal hysterectomy training and assessment. Median time to procedure completion was significantly higher in the novice group, whereas median estimated blood loss was no different between groups. No significant differences were observed in the composite median OSATS or VSSI scores between groups. The interrater reliability indices for subscales and composite scores of the OSATS and VSSI were high and ranged from 0.79 to 0.90 and 0.77 to 0.93, respectively. Conclusions: With further study, the Miya Model may be a useful tool for teaching and assessing vaginal surgical skills.
