Standardization of Interoperability in Health care Information Systems

摘要

This study examines the interoperability issues ofHealth care Information Systems, (HIS). With the evolutionof big data, Internet of Things, smart devices, ValueBased Health care and categorization of patient groups foroutcome measurements there is a great need for better HISswhich in an effective way is able to share data with eachother. Standardization is one recognized way of achievinginteroperability in information systems. Hence, in this casestudy we have researched the architectural drivers of hospitalwhich incorporates interoperability and which interoperabilitycharacteristics can be standardized via existing health carefocusedopen standard.Our results, gathered via nine semi-structured interviewsand analyzed through a thematic analysis, show that HISsobjectives are hindered by both design constraints and bytechnical, semantic and process interoperability issues. It alsoshows that there are open standards which are applicableto these, however this raised the question of why they in abroad scale are not. We therefore also discuss the possibilityof adding a forth category to the three previous forces that inmake up interoperability [15], [26]. This forth force we callinteroperability climate and it is defined as: Organizations’readiness to interact with each other under unanimouslydefined terms. It is inspired by the ”climate of innovation”and ”innovation value-fit” in the theory of InnovationImplementation by Klein & Sorra [16]. It incorporates theidea of how a bad climate of innovation and low intensityinnovation value-fit can prevent interoperability in HISs.
