Semantic Interoperability of Nursing Data – Mapping an Interface Terminology to SNOMED CT

Using nursing intervention data within the scope of eHealth from a primary system (hospital information system) in a secondary system (electronic patient dossier) requires a common terminology across systems. For this purpose, nursing interventions from the LEP nursing interface terminology widely used in Germany, Switzerland, and Austria were mapped to the international reference terminology SNOMED CT with the support of the National Release Center Switzerland. The completed mapping comprises 467 nursing interventions from LEP Nursing Version 3.5.0 mapped to pre-coordinated SNOMED CT version 2022-12-31 procedures. Moreover, 83 new submissions were included in the international SNOMED CT edition and seven in the Swiss SNOMED CT extension. As a next step, the mapping will be tested to examine the possibilities of semantic interoperability in nursing practice.
