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: Various and independent studies are showing that an exponential increase of chronic diseases (CDs) is exhausting governmental and private healthcare systems to an extent that some countries allocate half of their budget to healthcare systems. To benefit from the IT development, e-health monitoring and prevention approaches revealed to be among top promising solutions. In fact, well-implemented monitoring and prevention schemes have reported a decent reduction of CDs risk and have narrowed their effects, on both patients' health conditions and on government budget spent on healthcare. In this paper, we propose a framework to collect patients' data in real time, perform appropriate nonintrusive monitoring, and propose medical and/or life style engagements, whenever needed and appropriate. The framework, which relies on service-oriented architecture (SOA) and the Cloud, allows a seamless integration of different technologies, applications, and services. It also integrates mobile technologies to smoothly collect and communicate vital data from a patient's wearable biosensors while considering the mobile devices' limited capabilities and power drainage in addition to intermittent network disconnections. Then, data are stored in the Cloud and made available via SOA to allow easy access by physicians, paramedics, or any other authorized entity. A case study has been developed to evaluate the usability of the framework, and the preliminary results that have been analyzed are showing very promising results.IEEE journal of biomedical and health informatics. 01/2014; 18(1):46-55.
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: Healthcare is an increasingly collaborative enterprise involving many individuals and organizations that coordinate their efforts toward promoting quality and efficient delivery of healthcare. In cases where healthcare delivery is intended to be provided at patients' homes, the delivery process can be facilitated through the use of pervasive homecare systems. In such systems, interoperability is highly demanded in all the levels including the service and data levels. This paper presents a mediator-based approach for achieving interoperability in pervasive process-based healthcare systems built on a Grid infrastructure. The system's architecture is based on a Grid infrastructure upon which healthcare processes are automated using the Business Process Execution Language (BPEL). Client applications are portal-based, operate on mobile devices and can use radio frequency identification (RFID) technology for wireless capture of identification data. The proposed mediation framework enables decoupling of the healthcare processes and the underlying Grid middleware infrastructures. In particular, it resolves issues raised by both the diversity of the middleware infrastructures and the diversity of data formats and semantics used in the databases exposed by Grid middleware services. The framework is built on a software platform that exploits agent and workflow technology, thus providing robustness, high flexibility and fault tolerance in an environment as dynamic and heterogeneous as healthcare.Proceedings of the 2nd International Conference on Pervasive Technologies Related to Assistive Environments, PETRA 2009, Corfu, Greece, June 9-13, 2009; 01/2009
