Application of a Combined PBL and CBL Teaching Model Integrated with 3D-Body Software in Clinical Teaching of Pain Medicine

Abstract

Objective:
This study aimed to evaluate the effectiveness of a combined problem-based learning (PBL) and case-based learning (CBL) teaching model integrated with 3D-body software in the standardized residency training of anesthesiology.

Methods:
A total of 80 anesthesiology residents enrolled in the standardized residency program at the First Affiliated Hospital of Kunming Medical University from 2021 to 2023 were randomly assigned to either the experimental group or the control group, with 40 residents in each group. The experimental group received teaching based on the PBL+CBL integrated model together with 3D-body software, while the control group was taught using conventional methods. The effectiveness of the two teaching approaches was assessed and compared using surveys related to teaching satisfaction, as well as scores from departmental theoretical and clinical skills examinations.

Results:
There were no statistically significant differences in baseline data such as age, gender, and admission examination scores between the two groups (P > 0.05). In the assessments at the end of the rotation, the experimental group achieved significantly higher scores in both theoretical knowledge and clinical skills examinations compared to the control group (P < 0.05). Questionnaire results revealed that residents in the experimental group outperformed those in the control group in clinical skills, self-confidence, teamwork, and satisfaction with clinical teaching, with statistically significant differences (P < 0.05).

Conclusion:
The PBL+CBL hybrid teaching model, when combined with 3D-body software, can significantly enhance anesthesiology residents’ learning enthusiasm and initiative, improve their ability to integrate and comprehend knowledge, and better cultivate their competence in analyzing and solving clinical problems. This approach provides an effective reference for resident education in anesthesiology.
