Will SNOMED Codes be updated twice a year (in October and April) like Read codes?
Yes, new releases are provided for 1st April and 1st October each year. Suppliers implement these into their systems as soon as possible.

When is SNOMED CT being implemented?
UPDATED 3rd October 2018

SNOMED CT will go live across general practice in a phased approach from April 2018. In general this will be via two phases: behind the scenes changes and those that impact users. Deployment will commence with testing at pilot sites for each of the four principal clinical system suppliers: EMIS, TPP, Vision and Microtest.
National rollout schedules will be confirmed to practices by each supplier when their pilot activity has concluded.
A deployment schedule providing estimated dates is available on the Main Publications page of this website.

Can organisations create their own subsets or would you just limit a search field to a specified parent code?
The transition to SNOMED CT should not change existing functionality; where this is currently possible, it should still be available but using SNOMED CT.

How will Dual Coding Support the Change?
UPDATED 31 May 2018
Please see our Fact sheet on Dual Coding. (Found in Main Publications https://hscic.kahootz.com/connect.ti/t_c_home/view?objectId=300147)

What data quality measures are in place to ensure that translation from READ codes to SNOMED CT will not produce artefactual coding errors?
UPDATED 31 May 2018
The mapping tables have been reviewed by an expert reference group of GPs nominated by the Joint GP IT Committee utilising various software tools to guide their quality assurance. The maps utilise the existing Read/CTV3 maps which have been in use for many years as part of GP2GP. The recent work has improved the existing maps and will also address many of the maps that currently result in text degrades in GP2GP.

The maps will continue to be updated as SNOMED CT is updated and we would ask users to notify the terminology service if they identify any issues with the maps using the Terminology request portal.

Why can't primary care continue to map to SNOMED CT?
UPDATED 106.02
Currently there are two versions of clinical codes (Read v2 and CTV3) in existence within general practice, so not all GP systems use the same coding system and they do not provide the sophisticated features now expected from a clinical terminology.

The NHS needs a single clinical terminology (SNOMED CT) in order for clinical data to be exchanged accurately and consistently across all care settings; this will enable better patient care and improve the analysis and reporting of clinical data.

Read codes are only available in the UK whereas SNOMED CT is an international terminology, and using this will enable the UK to participate more effectively in research and analysis of health information to support national and global health care improvements.

The Read codes have a number of design restrictions that are already causing issues:

*Read v2 was designed for general practice; it is not possible to extend this to cover the requirements of all of healthcare due to its fixed 5 character codes. SNOMED CT provides content for all health and care.
–* In Read there is no mechanism to safely 'delete' out of date or erroneous codes. There are requirements to retire some of the codes in Read v2 and SNOMED CT enables these requirements to be met.
* Some areas of Read v2 are full and terms cannot be added where they logically need to sit. Therefore codes have been allocated into a 'vacant space'. Writing accurate reports then becomes problematic; in Read there are reports that are incorrect and have missed codes that are located in wrong areas of the terminology. SNOMED CT does not have these limitations and will address this issue.
* Where data is communicated electronically between GP practices, mechanisms have evolved to facilitate the two sets of Read codes (v2 and CTV3), however, because of the depth of detail that we know exists in SNOMED CT in secondary care, it is not possible to go from SNOMED CT back to Read.

Will Historical Data be coded in Read and SNOMED CT?
UPDATED 31 May 2018
Yes, all historical coded data in Read will have an associated SNOMED CT code; this will enable new SNOMED CT searches to function over historical data and will enable things such as time series analysis to continue when the system transitions to SNOMED CT.

Is there a central repository that catalogues all READ v2 / CVT3 codes and the corresponding SNOMED CT code?
UPDATED 31 May 2018
Files are provided by the UK Terminology Centre that provide the equivalent SNOMED CT code for each Read code. This can be obtained by downloading the NHS Data Migration pack from TRUD and contains supporting documentation. An access database that contains the above files and allows users to explore the equivalent codes is also available and is known as the UKTC Data Migration Workbench. There is now available a number of websites that provide look-ups on a Read code, these are listed on the "useful links" area of our website.

Having multiple coding schemes creates additional burden and cost to the NHS; being on a single terminology will allow practices to receive already coded Discharge Summaries from hospitals and reduce text degrades substantially in GP2GP.

What will happen to my reports?
UPDATED 31 May 2018
Existing reports will still run while dual coding is in place (see our fact sheet for more information on dual coding). Suppliers will manage the conversion of national reports such as QOF and users will be able to utilise these in new reports as you do now. However, for locally written reports, when practices start to use terms in SNOMED CT that do not have an equivalent code in Read, these reports will need to be updated and reviewed. It is not possible to automatically convert existing reports to include SNOMED CT content that is not in Read, although suppliers will provide an initial conversion of the existing report. See your supplier support centre for further details. End users should also contact their CCG to understand what training and support is available in relation to templates and searches; a webinar and supporting document on designing searches is also provided on this website in Main Publications.

What do I need to do as a practice?
UPDATED 1 June 2018
You can keep up to date on progress via our SNAP Update, which is published monthly, and your supplier support centre will provide specific information in relation to your system. The Newsfeed on this site also informs of the various stages achieved.
As a practice we recommend:
- that staff who will enter data gain some appreciation of SNOMED CT, either through eLearning provided by your supplier or the NHS Digital Exploring SNOMED CT Content webinar
- you undertake a 'spring clean' of all your reports and templates; archiving or deleting those that you have not used for over 12 months. They are probably out of date to run in Read.
- that staff undertake supplier training when available.
