Abstract: Objective: To study the application of case-based Learning (CBL) combined with Patient, Iinterventions, Comparisons, Outcome and Study design(PICOS) mode in standardized training for oral and maxillofacial surgery residents. Methods: A total of 60 oral and maxillofacial surgery residents from January 2021 to December 2021 were selected as the subjects. They were randomly divided into traditional LBL (Learn-based Learning) teaching group (28) and CBL combined with PICOS teaching group (32). At the end of the residency program, the theoretical knowledge assessment was carried out, and the clinical thinking ability was scored by mini-clinical evaluation exercise (Mini-CEX) scale, and the personal teaching efficacy and teacher efficacy were evaluated. Results: The basic theoretical knowledge, clinical case analysis and total scores of the experimental group were better than those of the control group; the scores of the experimental group in clinical judgment were higher than those of the control group; the satisfaction of the experimental group on the teaching form and teaching effect was higher than that of the control group; the personal teaching efficacy and general teacher efficacy and total scores of the experimental group were higher than those of the control group. The differences were statistically significant (P<0.05). Conclusions: CBL combined with PICOS model is superior to traditional teaching methods, which can improve the learning initiative, clinical diagnosis and treatment standardization and clinical decision-making ability of residential training physicians, and improve the teaching efficacy of teachers, which is worthy of further promotion.
