Abstract
This paper describes how the integration between one of the RIS-systems (Adapt) in VGR and the infobroker in the central archive is implemented. The project was presented in 2006 with the title Building an IT Healthcare Enterprise by taking the standards to the limits and sometimes beyond that. The Adapt RIS is used by the Sahlgrenska University Hospital (SU) in Gothenburg and handles 8 different radiology departments. The implementation is based on HL7 version 3 and the message exchange is based on Web Services/SOAP. The base of the RIS-system was developed in the beginning of the 1990:s by a company that no longer exists. SU has always been able to modify the system by changing the source code and we have been responsible for the system-development since late 1990s. We are using IBM Informix Dynamic Server that is running on a Solaris-based cluster with additional software from Veritas/Symantec. The communication is planned to be 2-way. Our RIS-system transfers order promises, various status updates during the workflow and finally reports with various status levels. Our system will be able to receive requests and reports from the broker. The broker in turn receives these messages from other hospitals in VGR (Vastra Gotalands Regionen). We use Axis2 to generate skeleton java-code based on WSDL- and XSD-files that defines the Web Services. Axis2 is an Open Source software that is developed as a part of the Apache project. Eclipse is a development environment for Java that we use and it is also open source. Apache Tomcat is the application server that we use to receive messages from the infobroker.
