PURPOSE

To elucidate the relationship between video game (VG) play and interventional radiology (IR) technical skills in medical students.

MATERIALS AND METHODS

Twenty medical students recruited at our institution's IR symposium completed a survey to ascertain demographics and prior VG experience, then participated in a 3-part trial of skills assessing IR and VG skill and visuospatial aptitude (VSA). IR skill was evaluated via an endovascular simulation task, VG skill by performance on three separate VGs, and VSA using the Cube Comparison test. Regression analysis was tested the strength of relationship between IR skill and VG experience, VG skill, and VSA, respectively, and participants were stratified by IR skill to top and bottom halves for survey-response comparison.

RESULTS

There was no correlation between either VG skill or visuospatial aptitude and IR skill (r = -0.22, p = 0.35; and r = 0.14, p = 0.57). Greater number of years playing VGs correlated with superior IR skill (Spearman's rho=-0.45, p<0.05). Students who selected IR as their specialty of interest had extensive VG experience, playing for > 15 years (n = 4, 80%), at least 10 hours per week at their peak (n = 3, 60%), and reported being either "skilled" or "highly skilled" at VGs (n = 3, 60%).

CONCLUSIONS

In our study, though limited by power, number of years playing VGs correlated positively with IR skills in medical students. Prior VG experience may predict an early advanced capacity to learn IR skills and an interest in the specialty.
