摘要
目的:开展冠状动脉CT血管成像人工智能辅助诊断技术(CCTA-AI)的临床使用成本分析研究,探讨引入人工智能(AI)前后冠状动脉CT血管成像(CCTA)检查成本差异及成本效果,分析AI技术的应用对公立医院高质量发展的影响。方法:采用作业成本法测算北京5家样本医院应用AI技术前后检查成本及CCTA效率变化情况,以诊断准确度作为效果值,计算CCTA-AI(AI组)与CCTA-人工诊断(医师组)的成本效果,分析影响单位成本的主要因素。结果:5家样本医院应用CCTA-AI后,例均检查成本为1074.90元,应用前为1266.61元,机构间检查成本差异较大;基于诊断准确度的成本效果分析显示,AI组成本为1074900元,效果为855.05人,医师组成本为1266610元,高年资医师组效果为815.07人,低年资医师组效果为793.40人,每检查1例患者能节约0.46人·时,AI组相较于医师组具有绝对优势。CCTA检查单位成本受多种因素影响,“年检查人次”“涉及CCTA检查的CT台数”对CCTA检查单位成本的影响最大。结论:应用CCTA-AI能够在一定程度上促进公立医院提质增效,有助于优化医疗资源总体布局,未来应进一步加强AI技术成本分析,以全面评估其在医疗体系中的实际贡献。
Objective:To carry out a study on the cost analysis of the clinical use of Artificial Intelligence-assisted Diagnosis Technology for Coronary CT Angiography(CCTA-AI)to explore the cost differences and cost effects of Coronary CT Angiography(CCTA)examinations before and after the introduction of Artificial Intelligence(AI),and analyze the impact of the application of AI technology on the high-quality development of public hospitals.Methods:The operation cost method was used to measure the changes in the cost and efficiency of CCTA examinations before and after the application of AI technology in five sample hospitals in Beijing,and diagnostic accuracy was used as the effect value to calculate the cost effect of CCTA-AI diagnosis versus CCTA-manual diagnosis,and to analyze the main factors affecting the unit cost.Results:The average cost of examination in 5 sample hospitals after the application of AI-assisted diagnosis system was 1074.90 yuan,and 1266.61 yuan before the application,with a large difference between institutions.The cost-effectiveness analysis based on diagnostic accuracy showed that the AI group had an absolute advantage over the manual group,with a cost of 1074900 yuan for the AI group and an effectiveness of 855.05 persons,and a cost of 1266610 yuan for the physician group,with an effectiveness of 815.07 persons for the high-year-end physician group,and an effectiveness of 793.40 persons for the low-year-end physician group;0.46 man-hours could be saved for each patient examined;the unit cost of CCTA examination was affected by a number of factors,among which"the number of annual examinations"and"the number of CT units involved in CCTA examination"had the greatest influence on the unit cost of CCTA examination.Conclusion:The application of AI-assisted diagnostic technology can promote the improvement of quality and efficiency in public hospitals in a certain extent,and help optimize the overall distribution of medical resources at the system level.In the future,the cost analysis of AI technology s
