Summary
A new software system objectively measures microsurgical skills, showing significant improvement in trainees after a 1-day course. This tool provides reliable assessment without patient risk.
Area of Science:
- Plastic Surgery Training
- Microsurgical Skill Assessment
- Surgical Education Technology
Background:
- Growing need for objective assessment in early plastic surgery training.
- Lack of validated, objective measures for microsurgical spacing and alignment.
- Introduction of a novel software analysis scoring system to address this gap.
Purpose of the Study:
- To introduce and validate a novel software system for objective microsurgical skill assessment.
- To measure improvements in spacing, alignment, and overall performance in a 1-day course.
- To provide a reliable and consistent tool for surgical trainees.
Main Methods:
- Images of sutured latex strips from the Microtrainer system were analyzed using calibrated online software.
- Sutures were quantitatively assessed for spacing, alignment, and density.
- A total score was calculated at the beginning (Score 1) and end (Score 2) of a 1-day course.
Main Results:
- Analysis included 38 microsurgical anastomoses from 19 participants (postgraduate years 1-7), most with no prior microsurgery experience.
- Mean Score 1 was -2, significantly improving to a mean Score 2 of 22 (p < 0.0001).
- Demonstrated significant improvement in candidate ability over the course of the day.
Conclusions:
- The Microtrainer system software offers a novel, reliable, and consistent objective assessment for surgical trainees.
- This method provides patient-risk-free evaluation and can efficiently demonstrate progress within a 1-day setting.
- While initial setup has costs, the system is timely and repeatable for skill development.
