Promoting Ubiquity and Interoperability among Health Information Systems Using an SOA Based Architecture

Abstract

Health information systems are of extreme importance and they became an intrinsic part of the healthcare sector. However, in today's molds and with the advent of the Internet and mobile devices, a paradigm shift, from the current isolated systems to interoperable distributed systems, that take advantage of ubiquitous computing, is needed. In critical situations, such as decision making in healthcare, it is necessary to have access to all of the patient's information; for the information must be reliable and must be accessed in an easy and fast way. The present work proposes an architecture that aims to answer the needs of interoperability between heterogeneous health information systems and the need for ubiquity of medical information. A prototype was developed that tries to provide interoperability through a service-oriented architecture using web services. A mobile component was also developed to enable ubiquitous access to medical information. This work is based on the authors' knowledge about the Portuguese National Health Service.

“…AlJarullah and El-Masri (2013), Lupse et al (2012), Brzezinski et al (2011), and Sernani et al (2013) use structured XML messages according to HL7 CDA. Although Mannaro et al (2013) and Plácido et al (2012) mention HL7, do not claim to use it. Fragidis et al (2016) make use of FHIR standard (HL7 Community; n.d.).…”
