Healthcare information system involves a wide range of collaboration among distributed organizations such as home care organizations, wound care clinics and outpatient surgery facilities which often needs to access to patient medical data which is distributed across several components, structured in multiple data models or formats and with different semantics and stored in heterogeneous feeder systems. The nature of heterogeneous and distributed in healthcare environment causes severe semantic conflicts whenever electronic patient data exchange is needed. It is essential that these components be able to inter-operate with each other and facilitated in heterogeneous medical information exchange over the internet while reducing patient care cost and meanwhile improving the efficiency of patient diagnose. This paper proposed a schema matching approach not only reconcile semantic conflicts but also bring integrated access to patient medical data by mapping dispersed patient information which is semantically match and presenting it to authorized healthcare user.
