Implementing healthcare interoperability utilizing SOA and data interchange agent

The proposed system utilizes concept of web services with a compliance of Service Oriented Architecture (SOA) and data interchange agent that converts medical data coming from wide-ranging healthcare service providers into a standard data interchange format. Here, two xml databases are used like, service provider database and patient profile database. These two databases may be in various system formats. So, there is a need to convert it into standard format before it is stored in the data repository (database). Whenever a patient gets treatment from the service provider, both databases are updated with respect to relevant information and at the same time, the information presented in both databases is also extracted. Whole process is implemented using the web services and the message is transferred using the SOAP protocol. Furthermore, the accessing of service customer or service provider details can be done only if the authentication is given from the security agent. Finally, the accessing of information from database is achieved efficiently with the help of proposed searching algorithm that reduces almost 33% time needed to retrieve the desired data from the database. This research will benefit the prevalent electronic health record standards such as Health Level 7 (HL7) [1], openEHR [28], CEN/ISO 13606 [29] working towards semantic interoperability for efficient searching of patient records and hence improved performance.
