Providing Semantic Interoperability for Integrated Healthcare Using a Model Transformation Approach
Authors: Barbara Franz, Herwig Mayr
Abstract
Integrated care and the achievement of high quality healthcare over institutional borders require technical and semantic interoperability between different healthcare providers. Thus, a meta model was devel-oped, based on the application of a system conformant to Integrating the Healthcare Enterprise (IHE) and the use of Clinical Document Architecture (CDA) as docu-ment format. This meta model combines the properties of several health information systems and different health service domains (HSD). For each HSD, a model can be derived, which de-scribes used IHE profiles, available document types to the point of coding systems used in exchanged docu-ments. Thus, it provides information about the domain, workflows, patient etc., which are used for the trans-formation into another domain. Using this model trans-formation, HSD models may be compared, checked and completed, where applicable. The results can then in turn be applied to the CDA documents. Thus, it helps to improve the communication among healthcare institu-tions. The evaluation of developed models and transfor-mations is conducted using genuine healthcare data, provided by e-Care, an IHE-conformant system for ex-change of healthcare data between several healthcare providers.
