Résumé
Objective:To evaluate the effectiveness of hands-on training and video demonstration in training of forceps delivery for residents.Methods:Forty nine residents who were rotating in the obstetrics department of Peking Union Medical College Hospital from 2019 to 2021 were enrolled. The residents were randomly divided into two groups: the instructor group ( n=24) was taught by hands-on training of forceps delivery and the video group ( n=25) was instructed by watching video demonstration. All the trainees completed the self-confidence questionnaire survey, and were evaluated by written tests and objective structured assessment of technical skills scoring system. Results:The scores of self-confidence in each item after the simulation training were higher than those before training in both groups; and there were no significant differences between two groups in the increment of scores(mastering knowledge: 1.54±0.98 vs. 1.40±0.71, U=266.68, P=0.480;mastering operation skills: 1.42±0.93 vs.1.80±0.87, U=233.47, P=0.161; mastering forceps structure: 1.63±1.10 vs. 1.88±0.93, U=261.63, P=0.416; confidence in independent operation: 1.13±0.90 vs. 1.00±1.08, U=287.74, P=0.799; evaluation of simulation training: 0.21±0.51 vs. 0.16±0.55, U=288.27, P=0.776). In the written tests, the scores of the instructor group were significantly higher than those of the video group (83.00±7.18 vs.70.56±10.37; t=4.86, P<0.001). In the practical operation, the instructor group significantly outperformed the video group in items of “right blade placement” (0.71±0.46 vs. 0.20±0.41, U=147.54, P<0.001), “objective total score” (6.17±1.46 vs. 4.72±1.65, U=155.49, P=0.003) and “correct traction” (0.85±0.31 vs. 0.56±0.51, U=213.86, P=0.036). Conclusion:Training delivered via hands-on instruction and demonstration was generally more effective than that delivered via video, although both groups show a increased self-confidence in learning and performing forceps delivery.
Résumé
@#It has been absent from an accepted criteria for normalization and quality control of the thoracic surgery until now. The ideal assessing instrument which will be used to evaluate the technical skills and surgical procedures should present a few vital characterizations below: objectivity, speciality in the content, detailed structure, and quantifiability. Objective structured assessment of technical skills (OSATS) has developed as a reliable method of surgical skills measurement. This article focuses on the history of OSATS and its prospect in the thoracic surgery area by reviewing relevant literatures.
