Achieving interoperability among healthcare standards: building semantic mappings at models level

Published: 20 February 2012 Publication History

Abstract

Resolving heterogeneities between data and processes paves the way for interoperability between different heterogeneous systems. Healthcare standards provide the base for interoperability between different Electronic Health Record (EHR) system. The problems related to data interoperability arise when two EHR system's are complaint to heterogeneous healthcare standards and want to communicate with each other. To achieve semantic data interoperability, there is need to resolve data level heterogeneity. In this paper, we propose system that enable high level of accuracy of mapping between heterogeneous healthcare standards model. The broader goal of data interoperability is achieved when these heterogeneities are resolved through ontology matching and generation of accurate mapping file, that helps in clinical message conversion from one standard to another. To justify claim we investigate HL7 and openEHR standards ontological mappings. We will discuss transformation of HL7 and openEHR models at high level and instance transformation at the realization level. The proposed approach provides accurate mappings that enables timely health information sharing among different healthcare systems to provide better healthcare to patients.

      Translating electronic health records (EHRs) into ontologies and then into other forms of electronic information is a challenging task. This paper focuses on the transformation of openEHR and Health Level Seven (HL7) standards. This process is mainly done to enable the sharing of health information between various healthcare systems. The authors first familiarize the reader with the HL7 and openEHR models. The paper then presents some information on the existing systems that are applied to this problem of translation: the Jini Health Interoperability Framework (HIF-J), Artemis, and plug and play electronic patient records (PPEPR). The authors provide a software architecture of their own to solve the aforementioned challenge; this architecture uses open-source ontology matching tools. They propose using manual ontology matching and present four algorithms used for mapping. The proposal to perform some amount of ontology mapping manually is a very interesting approach. The authors claim that the manual process increases the accuracy of the mapping technique. Overall, I found this to be a very well-written paper. It attempts to provide a solution to a very complex problem in health informatics. The presented architecture should be used to develop at least a prototype of a real system, which can be tested with the aim of developing effective ontology transformation software.
