A Scalable Healthcare Information System Based on a Service-oriented Architecture
Journal of Medical Systems, 2011Co-Authors: Tzu-hsiang Yang, Yeali S. SunAbstract:Many existing Healthcare Information systems are composed of a number of heterogeneous systems and face the important issue of system scalability. This paper first describes the comprehensive Healthcare Information systems used in National Taiwan University Hospital (NTUH) and then presents a service-oriented architecture (SOA)-based Healthcare Information system (HIS) based on the service standard HL7. The proposed architecture focuses on system scalability, in terms of both hardware and software. Moreover, we describe how scalability is implemented in rightsizing, service groups, databases, and hardware scalability. Although SOA-based systems sometimes display poor performance, through a performance evaluation of our HIS based on SOA, the average response time for outpatient, inpatient, and emergency HL7Central systems are 0.035, 0.04, and 0.036 s, respectively. The outpatient, inpatient, and emergency WebUI average response times are 0.79, 1.25, and 0.82 s. The scalability of the rightsizing project and our evaluation results show that the SOA HIS we propose provides evidence that SOA can provide system scalability and sustainability in a highly demanding Healthcare Information system.

hl7 middleware framework for Healthcare Information system
International Conference on e-Health Networking Applications and Services, 2006Co-Authors: Jenchiun Lin, Tzu-hsiang Yang, Chihuang Chen, Jiesheng Chang, Faipei Lai, Kaiping Hsu, Pohsun Cheng, Chiachang Wen, Junlian Chen, Siaolin HsiehAbstract:In this paper, a new middleware framework developed for the Health Information System (HIS) rightsizing project of National Taiwan University Hospital (NTUH) is proposed. The framework is basically a Service-Oriented Architecture (SOA). Challenges as formatting complex medical Information as well as integrating heterogeneous systems in our hospital are addressed by introducing HL7 and Web services standard into our framework. Finally, the performance of a operating HIS based on our framework is analyzed and presented to evaluate the efficiency of our design. Keywords—HL7, Healthcare Information system, web services, Service-oriented Architecture

A timed Petri net approach for verification of Territorial Healthcare Information Systems
2016Co-Authors: Sabri Hamana, Vincent AugustoAbstract:This paper addresses the performance evaluation and verification of territorial Healthcare Information systems. For this purpose, we propose a new class of timed Petri nets, called THIS nets (Territorial Healthcare Information Systems), which formally describes patient care-pathways, relevant Information flows and their interactions. THIS nets are then used for verification of the health Information systems and evaluation of their performances such as cycle time distribution and probability of Information availability at some target time. A real example of cancer patient Healthcare Information system is used to illustrate the usefulness of the proposed approach. We show that advanced Information system allows earlier start of the medical consultations and thus a more efficient care pathway.
