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.
