| Learning Objective #1: Describe the lexical and sematic mapping method used to compare the VHIL variables to SNOMED-CT and ICNP reference terms. |
| Learning Objective #2: Describe the congruency of findings between SNOMED-CT and ICNP and suggest future application of these reference terminologies to electronic retrieval. |
Purpose: Incorporating research findings into clinical practice is essential for promoting quality nursing care. Identifying research-based best practices would be maximized by using a reference terminology to compare findings across studies. This project compares two reference terminologies, the International Classification of Nursing Practice (ICNP) version one and Systematized Nomenclature of Medicine Clinical Terms® (SNOMED-CT), for use in mapping nursing concepts in the Virginia Henderson International Nursing Library (VHINL). This research is descriptive in nature. Method: Two teams independently examined the content coverage of SNOMED-CT and ICNP® for 95 randomly selected variables from the VHINL. SNOMED-CT allows for a consistent way of indexing, storing, retrieving and aggregating clinical data. SNOMED-CT is designed to support the entry and retrieval of clinical concepts in electronic systems and their communication in messages. ICNP Version 1.0 is a domain specific reference terminology for nursing practice and is a resource for the development of ICNP catalogues which are subsets of nursing diagnoses, interventions, and outcomes for select nursing specialties, areas of practice, and client conditions.. Outcome: Each reference terminology was evaluated for lexical and semantic mappings to source concepts from the VHINL.Findings: Partial or exact lexical matches of 75% and 58% were identified for SNOMED-CT and ICNP® respectively. No exact lexical match was identified for 42% of terms in ICNP and 25% in SNOMED-CT. The SNOMED-CT and ICNP term was a broader concept than the library term 64% and 57% respectively. No semantic mapping was identified 27% for ICNP and 17% for SNOMED-CT.Future Work: Each reference terminology can be used in representing nursing concepts. Clinical psychosocial concepts had the highest degree of lexical match (88-92%) while mapping to research concepts was low (no match 56-81%). Due to the type of VHINL variables which include clinical, education, and research concepts, various terminologies may be needed for adequate concept representation.
