Blockchain-based Enterprise Architecture for Comprehensive Healthcare Information Exchange (HIE) Data Management

Timely clinical data exchange has been the primary function of Health Information Exchanges (HIEs). However, there have been growing needs for sharing public health related data among government entities. Because the primary stakeholders for public health data are different from clinical data, data are stored over multiple systems, making the retrieval of related public health data items a hard process. In such situations, blockchain technology may be used to connect and securely exchange those scattered data items. In this paper, we proposed an enterprise architecture (EA) for HIEs to adopt blockchain technology so they could store and exchange both clinical and other health related data for efficient general public healthcare management. With the proposed solution, HIEs can not only exchange relevant data items, but also securely manage, record, and transfer complete health records. In our approach, we have incorporated a Hyperledger Fabric (HLF) Network blockchain technology that utilizes Blockchain as a Service (BaaS) to enterprise architecture so that HIEs can manage comprehensive health data.
