title: Information system interoperability in a regional health care system infrastructure: a pilot study using health care information standards.
abstract: The 1st and 2nd Regional Health Care System Authority of Central Macedonia (1st and 2nd PeSY) are two of the seventeen Regional Healthcare System Authorities in Greece. Every single PeSY aims to improve the level of quality that health care organisations offer as well as to control the expenditure of health care services provided by the health care organisations, Hospitals and Primary Care Health units. There is currently an urgent need for Regional Health Authorities to deploy integrated healthcare information system, based on secure networks. The limited interoperability of current hospital information systems (HIS) poses a risk for the management of patient related information since there is a difficulty to transform processed data into useful information and knowledge. Thus, a pilot system was developed to achieve data integration record synchronisation using the Health Level 7 protocol between the existing HIS of two Hospitals of Thessaloniki and the central Offices of the PeSY. The pilot was funded by the Third Community Support Framework (jointly funded by EU and Greece) funds in order to prepare the forthcoming major healthcare IT projects in Greece. It is shown that such a system is pragmatic, achieves data integration and provides acceptable integration costs.
