An Integration Approach of Healthcare Information System

Healthcare organizations today are still struggling with the integration challenges of heterogeneous information systems. Those system interfaces are not always compatible out of box, when the number of involved systems increases, complexity increases in an unmanageable way. Decentralized proprietary format data largely restricts the value of healthcare information. In this article, we present a healthcare information system integration approach based on an integration engine to address the integration problems. All the involved systems are connected to the integration engine through different interface adaptors. The integration engine takes the inbound message as the trigger event, generates outbound messages by workflow driver according to the workflow configuration file. The integration engine is also responsible for understanding the message context and converting the healthcare information into a unified format, and then storing it in the clinical data repository. Thus, it can facilitate the utilization and sharing of healthcare information.
