基于AI的分层带教体系对影像技术实习生技能提升的研究
Study on the impact of an AI-based hierarchical teaching system on the skill improvement of Imaging Technology interns
目的 探讨在临床带教中融入人工智能(artificial intelligence,AI)技术的分层带教体系对医学影像技术实习生专业技能提升的效果,从而优化传统教学模式,提高实习生的临床实践能力和职业素养。 方法 选取泸州市人民医院36名医学影像技术实习生,随机分为试验组(n=18)和对照组(n=18)。试验组采用基于AI的分层带教体系,包括岗前分层、AI辅助平台教学、分层技能实训和个性化辅导;对照组采用传统带教模式。实习结束后,通过理论考核、技能测试、问卷调查及教学反馈调查多维度评估教学效果。 结果 试验组的设备操作熟练度[(33.8±2.3)vs.(25.7±3.4)]、影像解读能力[(26.8±1.5)vs.(19.7±1.7)]、临床场景应对能力[(25.8±1.5)vs.(19.3±1.7)]及技能总成绩[(86.5±4.6)vs.(64.7±5.7)]均优于对照组(均P<0.001)。试验组理论知识考核成绩为(87.0±1.6)分,与对照组的(86.8±3.9)分比较,差异无统计学意义(P=0.914)。问卷调查显示,试验组在操作技能提升程度[(88.4±5.1)vs.(84.4±4.7)]、学习兴趣提升[(88.9±5.4)vs.(83.3±5.2)]、疑难病例分析能力[(89.3±6.1)vs.(81.7±4.2)]、学科知识面的扩展[(89.4±5.7)vs.(81.6±4.4)]及临床思维能力的提升[(88.9±5.2)vs.(80.5±4.2)]五个方面均优于对照组(均P<0.05)。教学反馈调查显示,基于AI的分层教学模式可提升临床决策效率、对教学体验满意及自信心增强的实习生比例,试验组均高于对照组(分别为88.9% vs. 38.9%、94.4% vs. 44.4%、88.9% vs. 33.3%,均P<0.05)。 结论 基于AI的分层带教体系能够提升医学影像技术实习生的临床技能,且有助于缓解带教教师的负担,提高教学效率与质量。
Objective To explore the effectiveness of integrating an artificial intelligence (AI)-assisted hierarchical teaching system into clinical education for improving the professional skills of medical imaging technology interns, so as to optimize traditional teaching models and enhance interns’ clinical practice capabilities and professional competence. Methods A total of 36 Medical Imaging Technology interns from Luzhou People’s Hospital were selected and randomly assigned to the experimental group and the control group, with 18 interns in each. The experimental group received an AI-assisted hierarchical teaching system, which included pre-training stratification, AI-assisted platform-based instruction, tiered skills training, and personalized guidance. The control group followed the traditional teaching mode. After the internship, the teaching effect was evaluated from multiple dimensions through theoretical assessment, skills testing, questionnaires and teaching feedback surveys. Results The proficiency in equipment operation[(33.8±2.3)vs.(25.7±3.4)], image interpretation ability [(26.8±1.5)vs.(19.7±1.7)], clinical scenario response ability [(25.8±1.5)vs.(19.3±1.7)], and total skill scores [(86.5±4.6)vs.(64.7±5.7)] of the experimental group were all superior to those of the control group (all P<0.001). There was no statistically significant difference in the theoretical knowledge mastery between the experimental group (87.0±1.6) and the control group (86.8±3.9) (P=0.914). The questionnaire survey showed that the experimental group outperformed the control group in five aspects: improvement in operational skills [(88.4±5.1)vs.(84.4±4.7)], enhancement of learning interest [(88.9±5.4)vs.(83.3±5.2)], ability to analyze difficult cases [(89.3±6.1)vs.(81.7±4.2)], expansion of subject knowledge [(89.4±5.7)vs.(81.6±4.4)], and improvement in clinical thinking ability [(88.9±5.2)vs.(80.5±4.2)], all with P<0.05. The teaching feedback survey shows that the AI-based tiered teaching model can increase the proportion of interns who can improve clinical decision-making efficiency, are satisfied with the teaching experience, and have enhanced self-confidence. The proportions in the experimental group are higher than those in the control group (88.9% vs. 38.9%, 94.4% vs. 44.4%, 88.9% vs. 33.3%, all P<0.05). Conclusions The AI-assisted hierarchical teaching system significantly enhances the clinical skills of Medical Imaging Technology interns, helps alleviate the burden on instructors, and improves teaching efficiency and quality.
