MDT联合CBL教学模式在医学影像专业学生的实习带教效果分析
Teaching effectiveness of MDT combined with CBL model in clinical internship training for medical imaging students
目的 探索多学科协作诊疗(multidisciplinary team, MDT)联合案例教学法(case-based learning,CBL)教学模式在医学影像专业学生的实习带教应用效果及应用价值。 方法 选取2023年1月—2024年1月在四川省人民医院温江医院(成都市温江区人民医院)超声医学科和放射科轮转的49名医学影像专业医学生为研究对象,随机分为两组,其中试验组24名,对照组25名。两组学生在超声医学科及放射科分别轮转8周,入科均进行第一次理论测试,每两周进行1次疑难病例讨论,其中试验组采用MDT联合CBL,对照组只采用CBL教学法。各科室轮转结束后对两组学生进行第二次理论测试,并进行电子问卷满意度调查。对比分析两组学生两次理论测试成绩、每次疑难病例讨论发言得分及满意度问卷结果。 结果 两组学生参加培训后的理论测试得分均较培训前明显增高(P<0.05)。从第4次至第8次疑难病例讨论,试验组学生得分逐渐高于对照组(P<0.05)。满意度问卷调查结果显示,试验组各项评分均高于对照组(P<0.05)。 结论 相对采用单一的CBL教学法,MDT联合CBL更能增加医学影像专业实习生的学习兴趣,学生的临床思维能力及对疾病的综合诊断能力也有更大的提升。
Objective To explore the application effectiveness and value of the multidisciplinary team (MDT) combined with case-based learning (CBL) teaching model in clinical internship training for medical imaging students. Methods A total of 49 medical imaging students from 2023 to 2024 were enrolled and randomly divided into an experimental group (n=24) and a control group (n=25). Both groups completed 8-week rotations in ultrasound and radiology departments, with initial theoretical testing upon department entry. During rotations, biweekly difficult case discussions were conducted, and the experimental group adopted MDT-CBL teaching, while the control group adopted CBL mode, followed by post-rotation theoretical tests and electronic satisfaction surveys in each department. Outcome measures included comparison of pre-/post-test scores, case discussion performance, and satisfaction ratings between groups. Results The theoretical test scores of both groups after training were significantly higher than those before training (P<0.05). From the fourth to the eighth discussion of difficult cases, the scores of the experimental group were gradually higher than those of the control group (P<0.05). The results of the questionnaire survey showed that the scores of the experimental group were higher than those of the control group (P<0.05). Conclusion Compared with CBL model, the MDT-CBL model demonstrates superior outcomes for medical imaging interns, including enhanced learning motivation, and significant advancement in clinical reasoning and comprehensive diagnostic capabilities.
