Objective To discuss how to improve the stability,reliability and security of the core servers of hospital information system.Methods Flaws on security were analyzed objectively in hospital server system adopting 'PC server & local hardisk' scheme.New schemes were put forward including both hot standby scheme based on concentrated storage and full redundancy scheme based on'minicomputer & diskette array'.Results It is proved that the full redundancy scheme is reasonable in theory,and usable in practice.Conclusion The mode of'minicomputer & diskette array' can effectively enhance the stability,reliability and safety of core servers.

OBJECTIVETo construct real world integrated data warehouse on re-evaluation of post-marketing traditional Chinese medicine for the research on key techniques of clinic re-evaluation which mainly includes indication of traditional Chinese medicine, dosage usage, course of treatment, unit medication, combined disease and adverse reaction, which provides data for reviewed research on its safety,availability and economy,and provides foundation for perspective research.

METHODThe integrated data warehouse extracts and integrate data from HIS by information collection system and data warehouse technique and forms standard structure and data. The further research is on process based on the data.

RESULTA data warehouse and several sub data warehouses were built, which focused on patients' main records, doctor orders, diseases diagnoses, laboratory results and economic indications in hospital.

CONCLUSIONThese data warehouses can provide research data for re-evaluation of post-marketing traditional Chinese medicine, and it has clinical value. Besides, it points out the direction for further research.

OBJECTIVETo discuss the feasibility and necessity of using HIS data integration to build large data warehouse system which is extensively used on re-evaluation of post-marketing traditional Chinese medicine, and to provide the thought and method of the overall design for it.

METHODWith domestic and overseas' analysis and comparison on clinical experiments' design based on real world using electronic information system, and with characteristics of HIS in China, a general framework was designed and discussed which refers to design thought, design characteristics, existing problems and solutions and so on.

RESULTA design scheme of HIS data warehouse on re-evaluation of post-marketing traditional Chinese medicine was presented.

CONCLUSIONThe design scheme was proved to be high coherence and low coupling, safe, Universal, efficient and easy to maintain, which can effectively solve the problems many hospitals have faced during the process of HIS data integration.
