Abstract
BACKGROUND: An increased demand for accountability and transparency in medicine have initiated a shift toward a more objective and standardized approach for postgraduate medical training. OBJECTIVE: To develop and evaluate an objective method to assess clinical competence of postgraduate year 1 surgery residents. DESIGN: Thirty-one postgraduate year 1 surgery residents, who had been trained in the Surgical School of Peking University First Hospital for one year, participated in an objective structured clinical examination as a final assessment of their clinical competence. A test station of irregular wound repair (debridement and suture) was specially designed to test the residents' surgical integrative competence in a complex-trauma treatment procedure. A modified global rating scale, in combination with wound area measurement, was applied to evaluate residents' surgical performance. The validity of the subjective global rating scale was evaluated by the objective measurement results from the software. RESULTS: The global rating scale score had no obvious correlation with the area of the removed tissue and the residual wound area after the suture. There was significant difference in the debridement time and the residual wound area between 0-3 and >3 total stitches. There were significant differences in the area of the removed tissue between 0 and 1-2 grey stitches and 0 and 3-4 grey stitches, and in the residual wound area after suture between 0 and 3-4 grey stitches and 1-2 and 3-4 grey stitches. CONCLUSIONS: An irregular wound repair procedure could be an effective method to assess the integrative competence of surgery residents. The training for surgical thinking in the early stage of junior residents needs to be strengthened. The entire measurement process was more complex and time-consuming than expected. The possibility of measurement by simply counting the numbers of the key spots might be explored in the future.
