Over the past two years, we have developed FHIR specifications for electronic service requests, specifically targeting pathology and radiology. Collaborating with the peak organizations representing these fields—the respective Colleges—we established national requesting value sets based on SNOMED CT. The Colleges leveraged existing catalogues to identify necessary content and gaps within SNOMED CT. These catalogues were then published as FHIR Value Sets, defined using SNOMED CT reference sets. Our decision to adopt precoordinated SNOMED CT codes aimed to simplify implementation, enhance user experience, and minimize ambiguity, while maintaining robust support for decision support and analytics. To demonstrate the practicality of these specifications, we created FHIR Smart forms and other implementation prototypes that incorporated ECL to create responsive experience, facilitating user feedback and further refinement. Within these demonstrations SNOMED CT is also used for other data elements of the request along.
Description
This work was part of the National Sparked eRequesting project - that is developing national specifications to be used across the whole of Australia.
Scope
SNOMED CT provided reasonable coverage, with mechanisms in place to promptly address any gaps. More importantly the underlying concept model can be exploited for decision support and analytics.
How SNOMED CT will be used
SNOMED CT is used to encode the content of diagnositic requests - primarily the service, but also specimens, sites and reason for presentation. The underlying FHIR Service Request resource is an international standard.
