1. 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

2. 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 pre- coordinated diagnostic concepts in ICNP and clinical findings in SNOMED CT –Phase 2: Cross-map between pre- coordinated intervention concepts in ICNP and procedures in SNOMED CT

3. 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; 2010AB 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 CliniClue browser.

4. 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 2011AB release.

5. Future Plan Re-examine the UMLS (2011AB) 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 UMLS2011AB 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.
