Abstract

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.
