基于数据中台的医用耗材数据资产管理价值研究

Research on the value of data middle platform in the management of data assets for medical consumable

目的:构建医用耗材数据资产数据中台,为医用耗材管理及应用开发提供开放性数据共享服务,降低数据孤岛风险。方法:基于数据中台数据资源管理模式,采用数据汇聚及大数据开发技术实现多业务系统间数据载入、整合及质量控制,通过数据仓库和对象建模方法建立层次数据管理体系,基于数据治理流程构建数据资产管理系统,为医用耗材数据资源提供数据标准及数据血缘维护、元数据管理、数据权限控制及数据生命周期管理等功能,采用微服务架构,为医用耗材管理提供数据服务生成、注册、发现及订阅等功能。选取解放军总医院第五医学中心南院区2020年3-5月医用耗材管理数据,测试业务应用数据中台数据,对比服务前后的前端数据应用开发工作量和应用操作时长。结果:医用耗材数据中台实现前端应用界面与后端数据服务链接,可为前端页面提供同步数据服务;数据中台数据服务前端数据应用开发工作量由传统数据仓库工作量的64人/月降至6人/月,测试应用操作时长由430 min降至16 min。结论:数据中台数据管理模式有助于提高医用耗材信息化管理能力和医用耗材管理效率,为医用耗材管理数字化转型提供借鉴。

Objective:To establish a data middle platform for data assets of medical consumables,to provide open data sharing services for the management and application development of medical consumables,and to reduce the risk of data silos.Methods:Based on the data resource management model of data middle platform,data aggregation and big data development technology were adopted to realize data loading,integration and quality control between multi-business systems.A hierarchical data management system was established through data warehousing and object modeling methods.A data assets management system was built based on the data governance process to provide functions of data standards and data lineage maintenance,metadata management,data permission control,and data lifecycle management for medical consumables data resources.A microservice architecture was adopted to provide functions such as data service generation,registration,discovery and subscription for medical consumables management.The front-end data application development workload of business data and application operation time before and after the application of data middle platform service of medical consumables were compared in the South Campus of the Fifth Medical Center of PLA General Hospital from March to May 2020.Results:The medical consumables data middle platform realized the connection between the front-end application interface and the backend data service,and provided synchronized data services for the front-end pages.The workload of front-end data application development for data middle platform data services decreased from 64 person-months of traditional data warehouses to 6 person-months,and the operation time for testing applications reduced from 430 minutes to 16 minutes.Conclusion:The data middle platform management mode is helpful to improve the information management capabilities and efficiency of medical consumables management,and provides reference for the digital transformation of medical consumable management.
