Application of TRIZ theory in clinical teaching in orthopedic operating room / 中华医学教育探索杂志

ABSTRACT

Objective:To investigate the role of TRIZ theory in clinical teaching in orthopedic operating room.Methods:A total of 43 interns in the orthopedic operating room of our hospital from October 2019 to July 2020 were selected as control group, and 46 interns in the orthopedic operating room of our hospital from August 2020 to May 2021 were selected as observation group. The interns in the control group received traditional teaching, and those in the observation group received teaching based on TRIZ theory. The two groups were compared in terms of professional assessment results, self-evaluation, satisfaction score, and qualification of aseptic operation in orthopedic operating room. SPSS 22.0 was used to perform the t-test and the chi-square test. Results:Compared with the control group, the observation group had significantly higher theoretical knowledge score, practical skill score, and weighted total score ( t=14.90, 11.82, and 13.23, all P?0.001). Compared with the control group, the observation group also had significantly higher scores of analysis and problem-solving ability, clinical thinking, doctor-patient communication, psychological quality, clinical case analysis, self-study ability, and teaching satisfaction ( t=7.88, 11.78, 15.26, 7.94, 12.93, 9.83, and 13.22, all P?0.001). Compared with the control group, the observation group had significantly higher qualified rates of surgical hand-washing, wearing sterile surgical gowns, non-contact glove wearing; and bacteriological testing ( χ 2=4.22, 6.02, 4.92, and 7.59, P=0.040, 0.014, 0.027, and 0.006). Conclusion:TRIZ theory has a certain value in clinical teaching in orthopedic operating room and can significantly improve the scores of theoretical knowledge and practical skills, strengthen aseptic operation abilities in orthopedic operating room, and enhance the satisfaction with teaching among interns.
