Finding SNOMED-CT codes which are QOF

API Platform
1

Hello,

With the UK SNOMED-CT dataset, the current approach we’ve taken with identifying if a particular SNOMED-CT code is part of QOF (quality and outcomes framework) is by doing a similarity search on a set. This set contains QOF-like SNOMED-CT codes that we manually curated.

I was wondering if there is a tell-tale way to know if a particular SNOMED-CT code is part of QOF (i.e. a property as straightforward as active, which takes 0 or 1).

Please let me know your thoughts.

Thanks in advance,

Faraz

Hello @Faraz_Malik

The basic statement to see if a code is in a SNOMED reference set is below, also see Valueset-operation-validate-code - FHIR v4.0.1:

Using the Shrimp browser (further details below) you can build up your SNOMED ECL query to get all the members of a reference set, this goes into .

The SNOMED Code you want to validate is in the reference set is added as .

Example of creating .

One of the QOF reference sets on the Terminology Server is: 12464001000001103|Quality and Outcomes Framework general practice extraction - statins prescribable within general practice simple reference set|.

The human readable ECL to get all the members of this reference set would be:

^12464001000001103|Quality and Outcomes Framework general practice extraction - statins prescribable within general practice simple reference set|

The computer readable ECL statement to get all members of the reference set is:

^12464001000001103

The url that identifies the value set to return all the members of this URL is below (note it is HTTP encoded). Using the shrimp browser use the “Copy ValueSet” button to create this URL.

http://snomed.info/sct?fhir_vs=ecl/^%2012464001000001103%20

This URL then gets added to the above statement as /

Shrimp Browser

Using the Shrimp browser you can visually query SNOMED using ECL on the Terminology Server. A link to Shrimp browser and further videos on how to use Shrimp and query using ECL is available here: Learn about the NHS England Terminology Server - Delen: Home - NHS England.

One of the QOF reference sets on the Terminology Server is: 12464001000001103|Quality and Outcomes Framework general practice extraction - statins prescribable within general practice simple reference set|.

Further detail about PCD / QOF reference sets.

This link is to the Primary Care Domain reference set portal: Microsoft Power BI where you can find all the QOF reference sets.

The NHS England Terminology Server contains SNOMED CT UK Edition, which contains some of the QOF reference sets, but not all. This is because PCD publish their own release of SNOMED CT which can be downloaded here: Primary Care Domain reference sets – NHS TRUD. This additional release of SNOMED should be added to the SNOMED CT UK Edition. We are working to get this on the terminology server, but no timescales at this time. So in summary not all QOF reference sets are available on the Terminology Server.
