Return to May 2016 Proposals

CDS Enablement Services

If creating a client, this track should require minimal work in advance of the connectathon, though at least a bit of preparation/reading on FHIR is recommended. If creating a server, advanced preparation will be required, but this scenario should somewhat limit the effort involved.

Pre-requisites: none

Submitting WG/Project/Implementer Group

Clinical Decision Support (CDS) with support from Service-oriented Architecture (SOA)


In order to provide effective and timely clinical decision support, a number of enabling infrastructure capabilities are necessary. This track explores and exploits capabilities available within the FHIR spec, and will illustrate how SOA services can complement these core capabilities as part of enablement of CDS.
