The SynEx project aimed firstly at producing a portfolio of products enabling a comprehensive sharing of health information - patient records as well as related medical information and secondly at demonstrating the integration of the various solutions and products proposed.
Different types of products have being developed, of which the principal ones are concerned with:
· data sharing (management of federated electronic patient records),
· data interpretation (through the use of terminology services),
· data presentaUon (forms, protocols),
· security (authentication, management of user profiles),
· data exchange (data converters, mediation services)
· etc.
Tools for securing the transmission of data over the Internet are of course also part of the proposed and recommended portfolio.
All these elements have been implemented as independent components, enabling their use in many different configurations as well as environments.
Apart from the evident computer-science benefits of this approach (better reusability, portable applications, generic components), the project's goals were mainly directed towards quality and efficiency of the healthcare process. The major contributions of the project in this respect comes on one side from the infrastructure and the tools that enable a higher availability of the right information at the right place, enabling improved or faster diagnosis, and on the other side from the availability of more useful data leading to a reduction of the duplicate examinations when a patient's care are performed by several entities.
The results of this project are demonstrated in various demonstrator sites. One of the principal ones is the Geneva one, where a prototype of regional healthcare network has been set up thanks to a close collaboration between the University Hospitals of Geneva and the Geneva's Associations of GPs (General practitioner's association, AMG). The network is also used now for implementing secured databases with restricted access, supporting closed users groups working on specific trials or studies. While part of the products are simply demonstrated, it has to be noted that the secured infrastructure part from ASASIHIN and secure Web Server developed by Novasys is now used in true production for supporting SYNEX-based services like sending confidential documents from the hospitals to installed GPs and for accessing sensitive databases.
Built into the Web Server several components from other Synex partners are working together. Those components are : the authentication tool from ASAS with encryption tunnel, the authorization tool (data base access control) from TietoEnator Sweden which allows the physician to access only to the data he is allowed to use. In this case patient could give authorization to trusted physician to access only data he allows him to access.
