Abstract:

Objective: Data exchange and interoperability are necessary to support modern healthcare. The purpose of this study was to use a data envelopment analysis (DEA) approach in order to evaluate the degree of efficiency and interoperability of Information Technology within Greek Regional Health Authorities. Methods: Publicly available data were collected from the Greek Information Society organisation regarding specific IT attributes of relevant Greek healthcare organisations for the period 2000 until 2006 and a DEA approach was applied against them. Inputs were network and software infrastructure and outputs were interoperability, data exchange mechanisms and ability to support open standards. Results: Results obtained for 15 of the 17 healthcare regions clearly demonstrated limited utilisation of the physical and software infrastructure for achieving interoperability. Conclusion: Based on the fact that the input data reflect a specific period of time, there is a need to increase the level of interoperability amongst existing healthcare information systems within the healthcare regions in Greece. Key factors in achieving this will be standardisation, and the adoption and introduction of new, open technologies. © The Journal on Information Technology in Healthcare 2008.
