【摘要】 目的：基于医院管理视角，比较传统手动注射模式与自动高压注射模式在冠心病介入治疗中的经济性差异，分析其成本及资源利用效率，为临床实践和医疗管理提供决策依据。方法：通过现场问卷调查、关键知情人访谈和专家咨询，收集样本医院心内科导管室的成本及时间消耗数据。采用时间驱动作业成本法核算冠状动脉造影和经皮冠状动脉介入治疗的成本，分析各类成本占比差异，为优化资源配置提供依据。结果：总成本归集后，使用手推式注射器的冠状动脉造影和经皮冠状动脉介入治疗的总成本分别为2 802.56元/例和13 348.45元/例；使用自动高压注射系统的冠状动脉造影和经皮冠状动脉介入治疗的总成本分别为2 700.00元/例和13 587.92元/例。在总成本构成上，冠心病介入诊疗相关流程中卫生材料占比最高，其次为设备资源和人力资源。结论：自动高压注射系统能显著提升手术效率、优化资源配置并降低人力成本，尤其适应DRG支付方式改革下的成本控制需求。更多还原

【Abstract】 Objective:Based on the hospital management perspective,it aims to compare the economic performance of conventional manual injection versus automated high-pressure injection systems in coronary interventional procedures, and to assess costs and resource utilization efficiency to inform clinical and managerial decision-making. Methods:Cost and time data from cardiac catheterization laboratories in sample hospitals in 2023 were collected through on-site surveys, key informant interviews, and expert consultation. Time-Driven Activity-Based Costing(TDABC) was used to estimate the costs of coronary angiography(CAG) and percutaneous coronary intervention(PCI),and the distribution of cost components were analyzed to provide evidence for optimizing the resource allocation. Results:The per-case total costs of CAG and PCI using manual injection were 2 802.56 yuan and 13 348.45 yuan, respectively;corresponding costs using automated high-pressure injection were 2 700.00 yuan and 13 587.92 yuan. Consumables constituted the largest share of total costs,followed by equipment and labor. Conclusions: Automated high-pressure injection improves procedural efficiency,optimizes resource allocation,and reduces labor costs,aligning well with cost-containment requirements under DRG-based payment systems.更多还原
