Abstract
Purpose: To evaluate the technical skills of SET trainees in cardiothoracic surgery whilst undertaking a simulated coronary anastomosis. Methodology: All 24 (2015) RACS Cardiothoracic SET trainees carried out two simulated coronary anastomoses. 2 mm diameter silicone vessels were anastomosed end to side using 7-0 prolene. Each procedure was captured using two opposing camera angles. The images were synchronised, edited and combined to provide the surgeon assessor with a single high definition movie comprising three views of the anastomosis. This movie was scored according to the Fann Objective Structured Assessment of Technical Skills (OSATS) score. Results: An independent sample t-test demonstrated the mean Fann OSATS score was significantly higher for SET4-6 trainees when compared with SET1-3 trainees. Mean Score (±SD) for SET1-3 = 20.83 ± 6.22 for SET4-6 = 24.15 ± 5.71 a difference of 3.32 (95% CI, -6.5 - -0.1), t(54) = -2.068, p = 0.043. Conclusion: We have applied an OSATS scoring system to a cohort of SET trainees and demonstrated that it is possible to differentiate between junior and senior trainees based on this scoring system. We believe this will provide a reliable quantitative method of assessing progress in training on a regular basis.
