Middleware based Inpatient Healthcare Information System.
ABSTRACT The paper presents a multi-tier, integrated, distributed, inpatient healthcare information system based on service oriented architecture (SOA) .NET environment in National Taiwan University Hospital (NTUH). The architecture and outcomes of the newly developed inpatient information system (IIS) platform are discussed in details. We also present mechanisms of integration as well as interoperability among the components and multi-database in IIS via health level seven (HL7) Middleware layer. The preliminary performance of the current operating IIS is evaluated and analyzed to verify the efficiency and effectiveness of the architecture we designed.

ABSTRACT: Healthcare is an increasingly collaborative enterprise involving many individuals and organizations that coordinate their efforts toward promoting quality and efficient delivery of healthcare through the use of interoperable healthcare information systems. This paper presents a mediator-based approach for achieving data and service interoperability among disparate and geographically dispersed healthcare information systems. The proposed system architecture enables decoupling of the client applications and the server-side implementations while it ensures security in all transactions. It is a distributed system architecture based on the agent-oriented paradigm for communication and life cycle management while interactions are described according to the workflow metaphor. Thus robustness, high flexibility and fault tolerance are provided in an environment as dynamic and heterogeneous as healthcare.Studies in health technology and informatics 02/2009; 150:180-4.

Conference Paper: Standard-based Data and Service Interoperability in eHealth Systems[Show abstract] [Hide abstract]
ABSTRACT: International standardization in information representation, organization, and dissemination are meant to eliminate the discrepancies in communication among participating organizations and institutions in a particular domain. The management of domain information will then allow different participants to integrate their legacy information or application servers to a nation-wide network and use widely approved services to communicate their proprietary data and services with a large group of clients. In this context, traditional healthcare information systems require fundamental re-engineering to new network-centric environments in order to reduce the huge costs of healthcare while maintaining the expected quality of public health. This integration using new HL7 v3 standards and leading-edge information technologies will be the initial steps for shifting towards an interoperable healthcare environment. This paper aims at addressing new challenges in standard-based interoperability provision among legacy healthcare information systems, while adhering to international and national standards for data and service representations. We introduce a framework to employ healthcare standards and clinical terminology systems to achieve semantic interoperability between distributed electronic medical record (EMR) systems. A real world case study for integration of a Clinical Decision Support System (CDSS) with the EMR of a specialist will be presented.Software Maintenance, 2008. ICSM 2008.

ABSTRACT: The implementation of a message communication server (MCS) for facing the syntactic interoperability problem in medical communications is the main target of this work. The background of this implementation was a set of recommendations for the types of exchanged messages, general architecture and end-to-end users services, which have been introduced by the authors in. MCSpsilas architecture facilitates different medical information systems to visibly handle real world events and information, without any interference in the basic structure of these systems. The performance of MCS has been tested in three distinct phases employing the application and data store entities of three cooperating medical information systems, a Laboratory Information System (LIS), an Advanced Radiology Information System (RIS) and a Picture Archiving and Communication System (PACS). The evaluation of the developed MCS was also performed and the extracted statistics validated the high degree of MCSpsilas effectiveness and efficiency.Proceedings of the 8th IEEE International Conference on Bioinformatics and Bioengineering, BIBE 2008, October 8-10, 2008, Athens, Greece; 01/2008
