Welcome to the Nursing Special Interest Group space!

The IHTSDO Nursing Special Interest Group (Nursing SIG) was a community of practice for the nursing profession, supporting worldwide nursing participation in the development, validation, uptake, implementation, and correct use of SNOMED CT and related products.

Following a reorganisation within SNOMED International this group has now ceased to exist.  However the Nursing Clinical Reference Group has been established with project and editorial groups established in relation to specific deliverables.  More information on Virtual Clinical Groups, and a list of others in the Directory - Clinical Groups is available.

An information sheet about the work of the former Nursing Special Interest Group can be found here

Please click here to read the Special Interest Group's Terms of Reference document, found on the IHTSDO website. 


We welcome participation from anyone interested in ensuring that SNOMED CT supports nursing requirements for electronic documentation and communication of patient care in any setting.

We encourage clinicians to participate and drive forward the work of SNOMED International and the development of SNOMED CT.

The former Chair and Vice-Chair of this SIG were Zac Whitewood-Moores and Roberta Severin respectively, who aim to remain actively involved in the work of the Nursing Clinical Reference Group and will be happy to be contacted in this transitional phase.

IHTSDO and International Council of Nurses (ICN):

IHTSDO and ICN have shared a commitment to harmonise SNOMED CT and ICNP (International Classification of Nursing Practise) since 2006 with a formal agreement instituted in 2010, renewed in 2014 focussing on delivering equivalence tables between ICNP and SNOMED CT for Nursing Diagnosis and Nursing Interventions. These products are now being released in a regular cycle as part of ICNP and SNOMED CT releases. The Nursing SIG provided international clinical validation and quality assurance and continues to do so as the products are maintained.
