Improving Service Accessibility in Service-Oriented HIS

Abstract

Nowadays, new trend in design and implementation of Hospital Information System (HIS) is towards using Web-based Service-Oriented Architecture (SOA). However, the standard SOA includes an insensitive service store through which the accessibility of some hospital services becomes difficult when their specification or network address are changed or missed. This paper discusses problems of insensitive service store and then presents a model where a sensitive service store is used to mitigate the problems. To show the efficiency of the proposed model, HIS of the Shahid Beheshti Hospital of Kashan including information systems of Admission, Outpatient, Ward, Pharmacy, Medical Document, Discharge and Insurance was designed and implemented with sensitive service store and its performance was considered.
