An NRC must therefore provide a mechanism for supporting requests from users, both related to the National Edition (where it exists) and International Edition of SNOMED CT. Requests for the International Edition should be communicated to SNOMED International, whereas requests for the National Edition must be managed locally.

How user requests are submitted to the NRC is up to each NRC to decide. An NRC can choose to have its own request submission system, but the solution could also be a simple mailing system or a file-transfer system. This depends on the level of SNOMED CT use (and hence, the number of requests) within the Member country. An NRC could decide to have a simple system in the NRC-establishment phase and then launch a more sophisticated system when the number of requests increases.

Content Request Service (CRS)

SIRS CRS is SNOMED International's online request submission system, which allows Member countries' NRCs and other authorized users to submit requests for change or addition of new content to the International Edition of SNOMED CT. Hence, all user requests for the International Edition of SNOMED CT should go via the NRC, and each NRC should have access to SIRSCRS. Concepts of only national relevance should not be submitted to SNOMED International. It is the responsibility of the NRC to determine which request is specific to its country and which are of international relevance. NRCs should be aware of the editorial principles for SNOMED CT and only submit requests that meet those principles.

Requests submitted to SIRS CRS are reviewed by SNOMED International Authors, and requests that meet the SNOMED CT International Edition inclusion criteria are added to the International Edition. SIRS CRS is an online tool, which enables users to view the current status of all requests that have been made through the system, see Figure 1110.page-break

Users are notified by email when a request changes status (accepted, not accepted, in process, or clarification requested). If a request is not accepted, a reason is provided to the requestor. A requestor who is unhappy with the reason for not non-acceptance can appeal using a formal appeals process.
