Federated healthcare record server—the Synapses paradigm

Abstract

The delivery of healthcare relies on the sharing of patient information between those who are providing for the care of the patient and this information is increasingly being expressed in terms of a ‘record’. Further, it is desirable that these records are available in electronic form as Electronic HealthCare Records. As it is likely that patient records or parts of records will be stored in many different information systems and in the form of disparate record architectures, uniform access to patient records would be problematic. This paper presents an overview of the Synapses computing environment in which a Federated Healthcare Record Server provides uniform access to patient information stored in connected heterogeneous autonomous information systems and other Synapses servers. The Synapses record architecture is based on the architecture proposed by the Technical Committee 251 of the European Committee for Standardisation and the interfaces to the Synapses server are specified in the ISO standard Interface Definition Language. Synapses is a pan-European project involving a number of hospitals, software companies, universities and research institutes and is partly funded by the EU Health Telematics Programme. The overview is described in terms of the Open Distributed Processing Reference Model.
