ABSTRACT
Objective To design the ISO15189 management information middleware based on laboratory information management system (LIS) and evaluate its application.Methods The ISO15189 management information middleware was designed based on LIS and the middleware technology as underlaying platform,and the multifunction management of LIS was implemented by the data warehouse technology and the data cleaning and extraction technology.Results The designed middleware made LIS implement the functions such as data exchange and transmission,data sharing,and data intelligence processing ISO15189 management information across multiple systems.It constructed a data warehouse by extracting,transforming,and loading useful data from multiple profession systems in laboratories,and flexibly presented data to the users by operating multidimensional data set from various aspects.Conclusion The ISO15189 management information middleware based on LIS has high value in the management of ISO15189 accredit,which may make the management work more standard,efficiency,and intelligence.
ABSTRACT
In this paper, through in-depth study on characteristics of hospital information system (HIS) construction and requirements of medical data integration, and combined with the medical data straits of heterogeneity, multi-source, complexity, dynamic growth, etc., the problem of information exchange in different systems was aimed to solved, in order to realize medical data sharing among internal systems in hospital.Based on Extensible Markup Language (XML), public data model was described by XML Schema technology. Global and local medical data were queried using XQuery technology. The results showed that a medical data integration platform based on HL7 standard and the middleware technologies were proposed. It was concluded that the platform shielded the heterogeneity of underlying medical data by middleware technology. It finally realized the global query and transparent access of medical data in HIS for users.
ABSTRACT
After the key technologies used in mobile reading service of library were compared , the authors pointed out that copyright and privacy protection were the major issues challenging the mobile reading service of library.Its development was prospected .
ABSTRACT
BACKGROUND: Test results in a laboratory are simply relayed to the laboratory information system through the interface. Middleware facilitates and manages the interaction between applications across heterogeneous computing platforms. We applied middleware to automated hematology analyzers in a clinical laboratory. METHODS: We used HemLink (Beckman Coulter Korea, Korea) as middleware between the laboratory information system and hematology analyzers. It provides quality control programs including the Westgard multirule chart and moving averages. RESULTS: Unlike the previous system, middleware does not require manual input of the quality control results. Amendment of quality control, if necessary, could be done without the help of hospital information teams. Identification of abnormal results with patient information could be achieved with moving averages. Morphology flags and system flags are checked at remote computers. CONCLUSIONS: Management of quality control results of hematology analyzers was easy via middleware. Thus, middleware could be useful to connect proficiency testing programs with HemLink and to compare results from laboratories using the same middleware.

O aumento nas demandas por gerenciamento, controle e monitoramento das informações na área da automação hospitalar tem promovido um maior volume de pesquisas que são indutoras do processo de inovação tecnológica na área da saúde. Neste contexto, um aspecto considerado importante na automatização do monitoramento de pacientes consiste na eficiência em detectar e informar em tempo hábil as anomalias encontradas nos sinais vitais dos pacientes. O procedimento de notificar as ocorrências dessas anomalias à equipe médica pode ser implementado por meio da geração e envio de alertas (sonoros ou visuais). Verificando a relevância desse tipo de demanda no ambiente hospitalar, o presente artigo descreve uma arquitetura que tem como fundamento a geração e o envio de alertas, cujos dados são advindos de pacientes internados em Unidades de Terapia Intensiva (UTI). A premissa foi, portanto, otimizar o processo de comunicação das anomalias detectadas de modo que a equipe médica responsável seja notificada de tais eventos de maneira mais eficiente. A arquitetura de comunicação, definida para o ambiente hospitalar, baseou-se em estudos realizados na UTI do Hospital Universitário Onofre Lopes (HUOL). Tais estudos possibilitaram uma análise de requisitos que permitiu definir um gerador de alertas personalizados, e o envio desses para dispositivos móveis das equipes médicas. O processo de envio dos alertas foi baseado em um algoritmo de escalonamento de tempo real, fazendo uso de um middleware e de computação móvel e distribuída, sendo esses os aspectos inovadores dessa arquitetura.
The increase in demand for the management, control and monitoring of information in hospitals has promoted a greater volume of research that induces the process of technological innovation in healthcare. In this context, an important aspect to consider in the automation of patient monitoring is the efficiency to detect and report anomalies in patients vital signs in a timely manner. The procedure for notifying the medical staff of these anomalies can be implemented by generating and sending alerts (either audible or visual). Noting the relevance of this demand in the hospital environment, this paper describes an architecture based on the generation and transmission of alerts, whose data are coming from patients hospitalized in intensive care units (ICU). The premise was therefore to optimize the procedure for reporting deficiencies so that the medical staff in charge is notified of such events more efficiently. The communication architecture in hospitals, used in this paper, was based on studies conducted at the ICU of the University Hospital Onofre Lopes (HUOL). These studies allowed an analysis of requirements that lead to the definition of a generator of custom alerts, and the sending of these alerts to mobile devices kept by medical staff. The process of sending those alerts was based on a real time scheduling algorithm making use of a middleware and both mobile and distributed computing, which are the innovative aspects of this architecture.
