Abstract:
Objective:To evaluate the role of virtual bronchoscopy intelligent system in improving the theory and operation level of bronchoscopy in pulmonary and critical care medicine (PCCM) teaching for standardized training specialists.Methods:A total of 50 PCCM physicians who had participated in virtual bronchoscopy training in Xijing Hospital, Air Force Medical University from 2018 to 2021 were selected as research subjects. In this study, self-controlled method was adopted to evaluate the change of assessment indicators after 1 week and 2 weeks of training. Questionnaire survey was also used to evaluate the training effect. SPSS 23.0 software was used for paired t-test and Chi-square test. Results:All the 50 PCCM physicians successfully completed the training of virtual bronchoscopy operation. The theoretical score was significantly improved after the training [(80.0±5.2) points vs. (92.4±3.8) points]. The basic operation time [(1 050.9±103.3) s vs. (386.4±47.7) s], and the number of hitting the bronchial wall [(88.3±12.7) times vs. (27.0±5.3) times] were significantly reduced. The recovery rate of alveolar lavage fluid [(27.6±7.4)% vs. (58.0±8.2)%] and the positive rate of biopsy [(19.2±13.1)% vs. (86.8±10.8)%] were significantly increased. The learning curve of the final score indicated that the score improved more rapidly in the first week of training, and the score improved more slowly in the second week of training. Questionnaires before and after the training indicated that virtual intelligent training could significantly improve the confidence and proficiency of students in bronchoscopy.Conclusion:Through the systematic training of virtual bronchoscopy intelligent system, the PCCM physicians have significantly improved their theoretical knowledge and operational proficiency. Therefore, the virtual bronchoscopy training system has practical significance for improving the overall training effect of clinical bronchoscopy for PCCM trainees, which is worthy of promotion.
