Evaluating alignment quality between iconic language and reference terminologies using similarity metrics

Abstract

BackgroundVisualization of Concepts in Medicine (VCM) is a compositional iconic language that aims to ease information retrieval in Electronic Health Records (EHR), clinical guidelines or other medical documents. Using VCM language in medical applications requires alignment with medical reference terminologies. Alignment from Medical Subject Headings (MeSH) thesaurus and International Classification of Diseases – tenth revision (ICD10) to VCM are presented here. This study aim was to evaluate alignment quality between VCM and other terminologies using different measures of inter-alignment agreement before integration in EHR.MethodsFor medical literature retrieval purposes and EHR browsing, the MeSH thesaurus and the ICD10, both organized hierarchically, were aligned to VCM language. Some MeSH to VCM alignments were performed automatically but others were performed manually and validated. ICD10 to VCM alignment was entirely manually performed. Inter-alignment agreement was assessed on ICD10 codes and MeSH descriptors, sharing the same Concept Unique Identifiers in the Unified Medical Language System (UMLS). Three metrics were used to compare two VCM icons: binary comparison, crude Dice Similarity Coefficient (DSCcrude), and semantic Dice Similarity Coefficient (DSCsemantic), based on Lin similarity. An analysis of discrepancies was performed.ResultsMeSH to VCM alignment resulted in 10,783 relations: 1,830 of which were manually performed and 8,953 were automatically inherited. ICD10 to VCM alignment led to 19,852 relations. UMLS gathered 1,887 alignments between ICD10 and MeSH. Only 1,606 of them were used for this study. Inter-alignment agreement using only validated MeSH to VCM alignment was 74.2% [70.5-78.0]CI95%, DSCcrude was 0.93 [0.91-0.94]CI95%, and DSCsemantic was 0.96 [0.95-0.96]CI95%. Discrepancy analysis revealed that even if two thirds of errors came from the reviewers, UMLS was nevertheless responsible for one third.ConclusionsThis study has shown strong overall inter-alignment agreement between MeSH to VCM and ICD10 to VCM manual alignments. VCM icons have now been integrated into a guideline search engine (http://www.cismef.org) and a health terminologies portal (http://www.hetop.eu).

Medical informatics and digital health multilingual ontology (MIMO): A tool to improve international collaborations

“…The advantages of using HeTOP as the hosting platform of MIMO are: The navigability capabilities between the different available thesauruses and ontologies allowing discovering if a search term exists in MIMO and provided resources; The interface is translated into 12 languages (partially or fully processed both by domain experts and online AI-based systems) to facilitate the platform used by a large community not always comfortable with English, similarly to other well-known environments; The possibility to get dynamically generated links to relevant search query results on PubMed, or at this time, CISMeF, the Catalog and Index of French Language Health Resources on the Internet [38] ; The frequent updates of the terminologies and ontologies hosted allowing to be enriched thanks to alignment processes MIMO, when relevant dynamically; HeTOP comprises capabilities of controlled vocabularies alignment and mapping [39] , [40] . Thus, the initial terms included in MIMO have been automatically aligned with the same ones existing in other terminologies and ontologies existing in HeTOP.…”

Análisis administrativo de la implementación de la historia clínica portátil en un hospital de Bucaramanga

“…Sumado a lo anterior, la historia clínica portátil extiende una responsabilidad de orden administrativo -gerencial, debido a que es el documento más importante para respaldar los procedimientos practicados, las complicaciones sufridas y los costos monetarios de quienes responden por cada paciente. En el actual sistema de salud colombiano, es el soporte vital para la construcción de una factura y poder recobrar el servicio prestado a una entidad promotora de servicio de salud contratante con la institución (Riffon et al, 2014); todo esto define una ruta crítica de manejo, supervisión, alcance e interpretación, con el fin de ser un garante de prestación del servicio de salud y un apoyo constante y latente en todo el registro y almacenamiento de datos clínicos, en favor de la institución, su público objetivo y su planeación estratégica.…”

Formalisation de la sémantique des langages iconiques. Méthode à base d’ontologie et applications

“…Par la suite, le langage iconique a été étendu et d'autres applications ont été développées : (a) l'association d'icônes dans les dossiers patients, pour en faciliter la lecture [30], (b) l'aide à la consultation des guides de bonnes pratiques critiques, qui contiennent souvent de nombreux cas particuliers que les icônes permettent d'identifier plus facilement [27], et (c) l'utilisation dans les moteurs de recherche médicaux, pour faciliter la lecture des listes de résultats parfois longues et fastidieuses [8].…”

“…L'utilisation de VCM dans les applications médicales nécessite son alignement avec les référentiels existants, afin notamment de pouvoir associer automatiquement des icônes aux ressources déjà indexées par les concepts de ces référentiels, comme par exemple les Dossiers Patient Informatisés. Les premiers alignements entre VCM et les terminologies médicales ont été réalisés de manière manuelle [8]. Dans cette section, nous étudions l'alignement semi-automatique avec la SNOMED CT, une terminologie couvrant les différents concepts médicaux, dont l'anatomie, les conditions cliniques, les procédures... Elle inclut de nombreuses relations entre ces concepts : des relations de subsomption est-un mais aussi des relations entre conditions cliniques et structures anatomiques ou morphologies associées (par exemple l'hépatite « est localisée dans » le foie et « a pour morphologie » l'inflammation).…”
