The purpose of this study was to map the North American Nursing Diagnosis Association (NANDA) nursing diagnoses to the International Classification for Nursing Practice Version 1.0 (ICNP) and to compare the resulting representations and relationships to those within SNOMED Clinical Terms (CT). Independent reviewers reached agreement on 25 (i.e. 64%) of the 39 parent-child relationships identifi...

OBJECTIVE Little information exists concerning SNOMED CT (systematized nomenclature of medicine-clinical terms) users. This report describes current impressions and preferences of direct SNOMED CT users regarding coverage, quality, and concept details, and the change request mechanism. DESIGN A 43-question anonymous survey distributed electronically to relevant online communities. MEASUREME...

Medical science and health care both possess a strong tradition of structuring their terminological knowledge through controlled vocabularies, such as nomenclatures, thesauri, or classification systems [1-6]. The availability of such resources mirrors the need for sharing a common understanding of the employed terms and the semantic relations holding between them. Community-wide efforts such as...

Semantic interoperability in healthcare can be achieved by a tighter coupling of terminology and HL7 message models. In this paper, we highlight the difficulty of achieving this goal, but show how it can become attainable by basing HL7 message models on SNOMED CT concepts and relationships. We then demonstrate how this methodology has been applied to a set of clinical observations for use in th...

OBJECTIVES Medical terminologies vary in the amount of concept information (the "density") represented, even in the same sub-domains. This causes problems in terminology mapping, semantic harmonization and terminology integration. Moreover, complex clinical scenarios need to be encoded by a medical terminology with comprehensive content. SNOMED Clinical Terms (SNOMED CT), a leading clinical ter...

SNOMED CT is the most sophisticated reference terminology currently available for the representation of healthcare. An unforeseen consequence of the opportunistic evolutionary process for SNOMED CT may be that some terms for disorders of specialised clinical domains are not represented within the terminology. The SNOMED CT July 2006 release was systematically examined using the CliniClue termin...

needs of practical applications with the importance of the purity and accuracy of the terminology is a very difficult task..’ We would actually state that it is impossible. We would assert that hierarchies are created for a purpose. The purpose could be to support automated maintenance of the terminology, to create definitional relationships, or to allow appropriate inferences. If the different...

Topic: A preliminary study on the reproducibility of results when mapping terms from an existing terminology to SNOMED CT post-coordinated expressions is described. Background: Implementing SNOMED CT requires a strategy for migrating existing systems and data that currently use other terminologies as well as ensuring that SNOMED CT contains suitable content that covers the domain. Mapping terms...

After a critical review of the present architecture of SNOMED CT, addressing both logical and ontological issues, we present a roadmap towards an overall improvement of this terminology. In particular, we recommend the following actions: Upper level categories should be rearranged according to a standard upper level ontology. Meta-class like concepts should be identified and removed from the ta...

We describe the framework for SNOMED RT (Reference Terminology), designed to complement the broad coverage of medical concepts in SNOMED with a set of enhanced features that significantly increases its value as a reference terminology for representing clinical data. We describe what is meant by a reference terminology, and differentiate SNOMED RT from specialized terminologies that enable user ...
