Applied Information Technologies for Development of Continuous Shared Health Care

This article describes procedures of development of an electronic health record for shared healthcare which include implementation of communication standard HL7 v.3, its application in the environment of existing hospital information systems (HIS) and modeling the semantics of the transferred data. The main part of the solution is so called HL7 broker that serves as a mediator in the communication between the two incorporated systems and implements procedures defined in the HL7 v.3 standard. Data models which represent the communicating systems towards the HL7 broker are based on the original data models implemented in HISes and are in the proper form, demanded by the HL7 standard. In order to achieve the semantic interoperability of incorporated system the creation of mapping of existing data models to international nomenclatures was necessary. Finally the possibilities of usage of international standards and nomenclatures in comparison to the national ones are discussed.
