Objective　Non-technical skills (NTS) are necessary to evaluate the comprehensive quality of surgeons. In this study

we proposed the concept of C-NTS

a scoring criterion for NTS based on real scenarios (for example

history taking) and video recording

and verified its practical application effects. Methods　Study objects were divided into the tutor group and the student group. The tutor group contained four senior attending physicians in gastrointestinal surgery department of one tertiary hospital (all male with doctor degree). The student group had four rotating surgeons who were randomly selected from the same department in 2018 (two males and two females). Before and after the training

the tutor rated the same anonymous video by C-NTS. One-factor analysis of variance was used to compare the differences between and within the groups

and Kendall concordant coefficient was used to test the consistency by SPSS 22.0. Results　After the tutor receiving training

Kendall concordant coefficient was increased from 0.425 to 0.853 and the latter suggested the difference had statistical significance (P=0.017)

which confirmed the effectiveness of the training. Conclusion　C-NTS has preliminarily solved the difficulty of homogenization of NTS assessment. Relevant C-NTS discussions and trainings for clinical tutors may be beneficial to save time and manpower in clinical teaching and evaluation.
