ABSTRACT
Objective:To explore the effectiveness of stratified teaching in improving the efficiency and quality of clinical teaching in the standardized training of residents in the department of prosthodontics.Methods:We enrolled a total of 297 participants who accomplished the standardized residency training in the Department of Prosthodontics of the Ninth People's Hospital Affiliated to Shanghai Jiao Tong University School of Medicine from January 2020 to May 2023. They were divided into stratified group (141 trainees from September 2021 to May 2023) and control group (156 trainees from January 2020 to August 2021). The stratified group received stratified teaching at three levels according to the trainees' major, training stage, and identity category, and the teaching theme and teaching method were set according to teaching objectives. The control group used a traditional teaching mode. The two groups were compared in terms of medical history taking, oral examination, case analysis, skill practice, and case report scores. SPSSAU was used to perform the t test and chi-squared test for data analysis. Results:The stratified group showed better performance in the final assessment: the case analysis score of the first-level trainees was significantly higher than that of the control group (85.72±4.14 vs. 83.00±6.38, P=0.003); the second-level trainees had a higher medical history taking score than the control group (88.20±7.14 vs. 85.38±5.63); the proportions of trainees rated as excellent in case report in the stratified group (the first level, 54.02%; the second level, 52.63%; the third level, 75.00%) were higher than those in the control group (the first level, 42.65%; the second level, 45.33%; the third level, 46.15%). Conclusions:In standardized residency training, the stratified teaching method can effectively improve trainees' case analysis, medical history taking, and case report abilities, and the effects in improving the skill practice level of trainees majoring in prosthodontics need to be further explored.
