Abstract [eng] |
The research is devoted to an integration of health information systems, when the interoperability should be utilised using different health informatics standards or their versions. To meet the integration goals, the theoretical model, closest to a particular situation of the Dainava outpatient clinic in Kaunas, had been chosen. Based on the model, the functional requirements for the middleware (integration) layer had been defined in order to ensure unambiguous links between patient data, stored in different systems. The middleware software prototype had been developed using messaging libraries for the HL7 versions v2 and v3. The middleware was successfully tested for automatic generation of orders for procedures and links to the procedure result data in the archive. The integration of the HL7 v2 and v3 coincidental components is achieved using trigger events for synchronous data manipulations. Such rules, implemented at the data layer, leads to less complex logics at business process layer and to lower number of data transformations. After automatic orders generation from referrals model implementation, we had to produce Worklist management system prototype to ensure full control of coming patient examinations. In this scenario DICOM based data models and terms had been chosen to use. |
