Abstract
Sensitivity of the health-related data and the focus on compliance and
security has traditionally emphasized the need for centralized approach while implementing Electronic Health Records (EHR) systems. These one-institutional architectural designs are leading to fragmented and scattered pieces of valuable data
across various data warehouses and silos. Interoperability challenges arise due to the
absence of unified data management and exchange mechanisms making the social
need for fundamental design changes bigger.
The capability of a distributed ledger technology and blockchain to offer immutable,
decentralized and cryptographically secured record of transactions throughout a
peer-to-peer network can facilitate better collaboration and increased interoperability in the field of health and insurance information exchange processes. The paper
examines different approaches and application of blockchain technology and identifies which implementations of components are more suitable and beneficial for the
specific eco-system analyzed in the paper.
This paper presents alternative way of dealing with information exchange across
multiple stakeholders by justifying the use of decentralized approach, distributed
access and solution how to comprehensively track and assemble health related data.
We propose an architectural design and overview of a specific use case with focus
on information exchange processes between health insurance providers and health
care organizations, by using blockchain as an underlying technology.
The architectural overview and data flows, backed up by sequence diagrams from
specific use cases offered in this paper, can serve as a guide to the blockchain technology adoption and initial setup.
