Abstract

Nowadays, having an electronic health record properly adopted by medical bodies is no longer a challenge. In fact, the critical issue for health practitioners is related to the exchange of health data between different institutes. While some existing standards provide interoperability for e-health systems, they still not offer a coherent solution that can be integrated and used easily. In this author, the paper present OpenEHR, a consistent health standard based on the dual-level scheme, which separates the reference model from the archetypes, allowing a flexible modeling of clinical concepts. However, getting into OpenEHR implementation can be very complex. The purpose of this article is to simplify the integration of OpenEHR, by introducing a stepwise methodology of the migration from legacy SQL-based EHR to an interoperable OpenEHR based NoSQL oriented document model. Successful consolidation was achieved through the deployment of metadata and mapping rules in Java environment project, which allowed a practical automation of the interoperability integration process.

The main focus for researchers regarding e-health platforms, is to achieve the interoperability aspect between health bodies (Gaynor, Yu, Andrus, Bradner, & Rawn, 2014). For that, myriad research studies are proposed in order to enhance the quality of care of patients. We can divide the related works into two parts:

The first one involves interoperability achievements based new EHR implementations. This includes every research study that was suggested in order to create an interoperable electronic health record system, starting with the design phase, followed by the processing and storage tools and accomplished by the integration of analytic modules. Here, the interoperability issue is normally studied within every step of the whole process and the proposed solution of health standards is represented as the basis of the entire ecosystem.
