在按病种分值付费（DIP）模式深化实施的背景下，医用耗材管理作为医院成本控制与医疗质量保障的核心环节，其监督效能直接影响医院运营效益。本文基于供应链溢出视角，以某医院医用耗材信息化管理实践为案例，从技术溢出、管理溢出、风险溢出三个维度，探讨信息技术对医院内部医用耗材监督管理的优化路径。研究表明，通过构建医疗器械唯一标识（UDI）系统、收拾耗占比动态监控、专项议价管控等措施，可实现监督技术跨环节渗透、管理标准全链条协同、风险防控全周期覆盖。实践表明，该模式有效控制了医院耗材的整体运营成本，并显著提升了高值耗材的用后结算管理水平，为公立医院构建精准、高效的内部监管机制提供了有价值的实践路径。

Under the deepening implementation of the diagnosis-intervention packet（DIP） payment model，the management of medical consumables serves as a core aspect of hospital cost control and medical quality assurance，with its supervision efficiency directly impacting hospital operational benefits．Based on the perspective of supply chain spillover，this paper takes the informatization management practices of medical consumables in a hospital as a case study，exploring the optimization paths of information technology in the internal supervision and management of medical consumables from three dimensions：technological spillover，managerial spillover，and risk spillover．The research shows that by establishing a unique device identification（UDI） system，implementing dynamic monitoring of the consumption ratio of medical consumables，and conducting special negotiation controls，cross-process penetration of supervision technology，full-chain coordination of management standards，and comprehensive risk prevention and control throughout the entire cycle can be achieved．Practice demonstrates that this model has reduced the hospital’s overall cost of medical consumables by 2.75%，increased the post-use settlement rate of high-value consumables to 80%，and provided practical references for public hospitals to establish a precise and efficient internal supervision system．
