One of the main challenges of exchanging patient care records between heterogeneous systems is the difficulty in overcoming semantic differences between them. This is further exacerbated by the lack of standardization in messaging protocols. As a solution to this problem, multiple ideas and standards have been proposed for exchanging clinical and administrative data in the healthcare area. However, most of these methods place some restrictions on the platform, standard or format, of the data. This paper proposes a context-specific, mediating schema-based architecture that enhances the transfer of electronic patient care records between healthcare information systems by using a reusable and portable model. The main contribution of this approach is its adaptability to a variety of schemas for the source and target systems.
