OBJECTIVE： To evaluate the research and application situation of Sunshine Medicine Electronic Monitoring Data Analysis System. METHODS： The Sunshine Medicine Electronic Monitoring data Analysis System based on business intelligence technology was introduced in respects of design process， development， implementation and application example. RESULTS： The whole architecture of the system mainly includes hospital business platform， data integration platform， information processing platform and application service platform； the functions of the system include medicine homepage show，single species analysis，antimicrobial agent analysis，national essential medicine analysis，injection analysis and sunshine medicine analysis. It can monitor the drug utilization in multi-angle and multi-level manners by building data center and creating multidimensional models. Besides， the system could solve the “drugs unified coding and information control” problems， “data collection and information integration” problems in different hospital， and “the efficient calculation and analysis of a large number of drug use data”. It can realize drug analysis and monitoring in the hospital， analysis and online monitoring of drugs prescribed by the doctor， finding， warning and evaluating abnormal phenomenon of drug use in the medical institutions， so that it is better for the supervisors to monitor the usage of drugs. CONCLUSIONS： The system with easy operation， flexible monitoring， rich chart shows， comprehensive monitor index has a positive effect on rational medication level.
