In consequence, the decision about which system and standard are more appropriate is difficult. The most widely deployed healthcare standard is Health Level Seven. Unfortunately, this standard has problems. The version 3 has seen slow adoption and the version 2.x had interoperability problems because of the variety of implementations by healthcare providers. To reduce the health interoperability problem between health information systems, we propose a canonical document for exchanging medical information. This document will be used as mediator between healthcare systems and shall allow health providers to share data among healthcare institutions without any adjustment or requirements. As result, the proposed mediator can make the exchange of health data simpler and efficient.

Hierarchical structures are used in diverse domains, in engineering and in research. We give a comparison between the various models cited in literature. This study allowed us to synthesize the most interesting of these models to represents the data trees.

The difficulty of this exchange is due to patient mobility and the presence of a large number of HIS in the world. Therefore, medical data are represented in heterogeneous formats that need to be integrated to build interoperate applications. Interoperability, independently of platforms, aims to ensure cooperation, communication and sharing information and services among several applications. To achieve interoperability in the medical field, we create a system for integrating heterogeneous Health Information Systems using the schema matching technique. The matching techniques are solutions to find automatically semantic correspondence between XML schemas in order to allow their integration in the information systems. The objective of our work is to create a new matching tool especially designed for the medical field. For that, we utilize the Metathesaurus in the Unified Med...

Indeed, the diversity of databases and the different representations of information sources make this exchange a very difficult task. Divers standards, (e.g. HL7: Health Level Seven; DICOM: Digital Imaging and Communication in Medicine), are created to enable the exchange and make health information systems interoperable. However, applying standardization requires changing the structure of existing healthcare systems. Our main purpose is to create a health document for exchanging health information between heterogeneous systems without applying changes on the internal structure of systems. The document uses the XML language to allow a structured and flexible exchange of healthcare data. The proposed health document can make the exchange of healthcare data among heterogeneous health information systems simpler and efficient.
