摘要目的:探讨人工智能（artificial intelligence，AI）辅助系统结合病例教学法（case-based learning，CBL）在眼科住院医师斜视专业教学中的应用。方法:将2020年1月至2021年12月在北京大学人民医院眼科规培的40名眼科住院医师作为研究对象，将其分为对照组和试验组，每组20人。对照组采用传统教学，试验组采用AI辅助系统结合CBL教学。专科培训结束时对两组学生进行理论知识、临床技能、临床思维考核，用问卷调查来评估教学效果。采用SPSS 26.0对数据进行卡方检验、单因素方差分析和独立样本 t检验。 结果:试验组理论知识考核成绩[（34.10±1.33）分]高于对照组成绩[（33.15±1.35）分]（ t=2.24， P=0.031），临床技能考核成绩[（24.75±1.02）分]高于对照组成绩[（23.60±0.82）分]（ t=3.93， P<0.001），临床思维考核成绩[（24.80±0.77）分]高于对照组成绩[（24.20±0.83）分]（ t=2.37， P=0.023）。对教学效果的评估，试验组在提升学习兴趣（ t=11.47， P<0.001），提升临床思维能力（ t=9.36， P<0.001），提升知识与技能水平（ t=17.71， P<0.001），加大知识共享程度（ t=31.17， P<0.001），整体满意度（ t=10.60， P<0.001）5方面评分均高于对照组。 结论:AI辅助系统结合CBL教学能提高眼科住院医师对斜视疾病的独立诊疗能力，建立正确的临床思维路径，教学效果良好。

abstractsObjective:To explore the application of artificial intelligence (AI) assistant system combined with case-based learning (CBL) in the teaching of strabismus specialty for ophthalmic residents.Methods:Forty ophthalmic residents who were trained in the Department of Ophthalmology of the People's Hospital of Peking University from January 2020 to December 2021 were divided into control group and experimental group, with 20 people in each group. The control group used the traditional teaching mode, and the experimental group used AI assistant system combined with CBL teaching. At the end of specialized training, the two groups were assessed for theoretical knowledge, clinical skills, clinical thinking and questionnaire survey, and the teaching effect was evaluated. SPSS 26.0 was used for Chi-square test, one-way ANOVA and independent-samples t-test. Results:The scores of theoretical knowledge [(34.10±1.33) points], clinical skills [(24.75±1.02) points] and clinical thinking [(24.80±0.77) points] in the experimental group were significantly higher than those in the control group [(33.15±1.35) points, t=2.24, P=0.031; (23.60±0.82) points, t=3.93, P<0.001; (24.20±0.83) points, t=2.37, P=0.023]. For the evaluation of teaching effect, the experimental group improved the learning interest ( t=11.47, P<0.001), clinical thinking ability ( t=9.36, P<0.001), knowledge and skill level ( t = 17.71, P < 0.001), knowledge sharing ( t=31.17, P< 0.001) and overall satisfaction ( t=10.60, P<0.001), and these 5 aspects were scored higher in experimental group compared with the control group. Conclusion:The teaching mode combining AI assistant system and CBL teaching can improve the independent diagnosis and treatment ability of ophthalmic residents for strabismus diseases, establish a correct clinical thinking path, and obtain a better teaching effect than the traditional teaching mode.
