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: This article describes the successful experiences of National Taiwan University Hospital (NTUH) in moving from IBM Mainframe to connected networking computer systems. We use multi-tier architecture and HL7 standard to implement our new outpatient Hospital Information System (HIS). The NTUH HIS is a complex environment with several operating systems, databases, and information systems. We adopt Service- Oriented Architecture (SOA) to reduce the complex relations between systems and solve data consistency problems among databases. We also show that the distributed architecture can provide us stable and reasonable system performances. Our main contribution is proving that the distributed environment with HL7 standard and SOA can sustain in a highly demanding environment.Proceedings of the IEEE Symposium on Computer-Based Medical Systems 01/2006;

Conference Proceeding: Dynamic Messages Creation Method for HL7 based Healthcare Information System[show abstract] [hide abstract]
ABSTRACT: This paper describes the method to create the HL7 message dynamically and make the HL7 middleware framework more efficient. The HL7 middleware framework was developed for exchanging the healthcare information in the National Taiwan University Hospital (NTUH). The framework is a Service-Oriented Architecture (SOA) and it contains the HL7Central Web Service. The Web Service makes the HL7 middleware framework more flexible and independent of programming language.e-Health Networking, Application and Services, 2007 9th International Conference on; 07/2007
