Demographic change, the migration of medical professionals and economic constraints are leading to an increasing specialisation and concentration of resources in the healthcare sector. The digital mapping of cross-enterprise process chains between different medical care levels in turn requires digital networking and syntactical and semantical interoperability in information exchange. Cross-enterprise electronic patient records based on the Cross-Enterprise Document Sharing (XDS.b) integration profile defined by the Integrating the Healthcare Enterprise (IHE) initiative are the basis of the digital exchange of medical information between patients and service providers. Syntactical interoperability is ensured by the object definitions in the XDS Affinity domain and the Clinical Document Architecture (CDA) document format. Semantical interoperability is achieved by the use of standardized terminology and code systems. Terminology servers make it easy to deploy standard ontologies and translate proprietary code systems. New interoperability standards, e.g. based on Fast Healthcare Interoperability Resources (FHIR), are being developed to facilitate the exchange of structured medical information objects on mobile platforms in the future.
