Mapping International Classification for Nursing Practice ICNP and

Mapping International Classification for Nursing Practice (ICNP) and SNOMED CT Submitted by the ICNP Programme Team to IHTSDO Nursing Special Interest Group 2 October 2011

Purpose • To promote and support implementations of SNOMED CT in clinical systems used by nurses through the provision of a maintained concept map between ICNP and SNOMED CT. – Phase 1: Cross-map between precoordinated diagnostic concepts in ICNP and clinical findings in SNOMED CT – Phase 2: Cross-map between precoordinated intervention concepts in ICNP and procedures in SNOMED CT

Method • Employed an automated process followed by human reviews. – Source terminology: ICNP Version 2 – Target terminology: SNOMED CT 2010 -07 -31 – A candidate cross-map was derived from the Unified Medical Language System (UMLS; 2010 AB release) for select ICNP nursing diagnostic concepts (n=239). – Two ICNP experts independently validated the candidate cross-map. Inter-rater reliability was measured between the two experts. – If semantics of ICNP and SNOMED CT concepts were not equivalent in the cross-map, a potential SNOMED CT candidate was identified through the Clini.

Preliminary Result • Of 239 ICNP concepts, 222 concepts (92%) were identified as semantically equivalent to concepts from SNOMED CT. • The cross-mapping table was submitted to National Library Medicine, for review and integration into UMLS 2011 AB release.

Future Plan • Re-examine the UMLS (2011 AB) cross-map for ICNP pre-coordinated nursing diagnostic concepts. – Source terminology: ICNP 2011 release – Target terminology: SNOMED CT 2011 -07 -31 • Derive a candidate concept map from the UMLS 2011 AB followed by human reviews. • Apply the same method for mapping of ICNP nursing interventional concepts to SNOMED CT. • Provide a concept mapping between ICNP diagnostic concepts and SNOMED CT concepts to users. • Repeat the method with ICNP nursing interventions.
