Abstract:
Objective:To design a medical big data center based on data warehouse(DW)and data service platform,to integrate information resources between different information systems and organizational structures,to build a secure channel for data sharing,and to meet the needs of clinical application data.Methods:Based on data flow direction,and according to hospital clinical services,operation management,and scientific research development,a top-down data application layer,data service layer,DW layer,and operational data storage(ODS)layer design architecture was adopted to design a medical big data center based on DW and data service platform.Guided by hospital data and business,according to the"object-event-report"data splitting logic,the activities corresponding to the roles in each subject domain were disassembled and sorted out to facilitate quick invocation in clinical applications.Results:The medical big data center was equipped with basic modules for patient master index management and master data management,covering 16 major business subject domains and 52 business subdomains,including hospital's clinical services,hospital management,and patient identification.The medical big data center application included clinical data center,operation data center and scientific research data center,and clearly defined the correlation logic between major categories of information,centrally managed the whole life cycle of service application program interfaces,combined master data information,comprehensively managed medical data,realized the normalization of hospital data,and established high-quality data assets and flexible DW models with the help of big data technology.Conclusion:The medical big data center based on DW and data service platform can integrate different information systems of the hospital with data within the hospital,realize the convenient invocation of interface services and the standardized and persistent management of hospital data,and ensure the data applications needs of clinical application,operational decision-making,and scientific research analysis.
