Evaluation of the utility of surgical simulation software in medical postgraduate education.

BACKGROUND

The use of medical simulation software in medical institutions is growing to address teaching challenges. The study aims to assess the effectiveness of the Touch Surgery app, a free medical simulation software, as a supplement to the teaching methodology of unified surgery for medical students.

METHODS

Twenty-three postgraduate students, divided into three groups based on residency training years, and five senior orthopedic surgeons took part in the study. Each participant completed three modules within the Large External Fixators module using the Touch Surgery app. The results achieved by orthopedic specialists and postgraduates in the test module were recorded separately. The orthopedic specialists' first test module scores were used as a baseline. A Likert survey assessed the usefulness and content accuracy of the app. Statistical analysis included analysis of variance and 2-tailed -test.

RESULTS

The first and second scores achieved by the postgraduates in the three groups were significantly different from the baseline of the orthopedic specialists, but the mean scores of all postgraduate's groups increased with simulator usage for learning and by the third attempt they were at the same level as the orthopedic specialists. However, no significant performance differences were observed between postgraduates with different training years. Postgraduates expressed a positive opinion of the usefulness and content of Touch Surgery in the questionnaire and their intention to continue using it in their future studies.

CONCLUSIONS

This study shows that the use of Touch Surgery improves postgraduates' performance and ultimately enables them to reach the level of orthopedic specialists in simulated surgery, and received positive ratings for the software's experience and content. Touch Surgery can be a valuable complement to traditional surgical teaching methods, bridging the gap between theoretical learning from textbooks and guided rehearsals of surgical steps and skills.
