Avaliou-se o desempenho terminológico, nos processos de indexação manual, automática e semi-automática, dos descritores, do Vocabulário Controlado do SIBi/USP, que representam o domínio da Ciência da Informação. Concluiu-se que os atuais descritores em Ciência da Informação do Vocabulário Controlado do SIBi/USP para representar adequadamente o conteúdo do corpus indexado devem ser ampliados e contextualizados através de definições terminológicas, de maneira a atender as necessidades de informação de seus usuários.; The terminological performance of the descriptors representing the Information Science domain in the SIBI/USP Controlled Vocabulary was evaluated in manual, automatic and semi-automatic indexing processes. It can be concluded that, in order to have a better performance (i.e., to adequately represent the content of the corpus), current Information Science descriptors of the SIBi/USP Controlled Vocabulary must be extended and put into context by means of terminological definitions so that information needs of users are fulfilled.

Em uma de suas definções, a Terminologia representa o conjunto de princípios e métodos adotados no processo de gestão e criação de produtos terminológicos, tais como glossários e dicionários de termos. A sistematização desses métodos envolve a aplicação de ferramentas computacionais específicas e compatíveis com as tarefas terminológicas, contribuindo para o desenvolvimento desses produtos e a difusão de conhecimento especializado. Entretanto, principalmente no Brasil, a combinação da Terminologia e Informática é incipiente, e dentre as atividades do trabalho terminológico é comum a utilização de várias ferramentas não especializados para esse fim. Isso torna o trabalho dos terminólogos muito moroso, pois esse trabalho geralmente é feito por uma equipe multidisciplinar que deve ter acesso, a todo o momento, à versão mais atual das várias etapas da geração de um produto terminológico. Além disso, deixa o gerenciamento dos dados mais complicado, pois não existe um padrão de entrada e saída definido para os programas. Apoiado nos pressupostos da Teoria Comunicativa da Terminologia (TCT), este trabalho apresenta a proposta de desenvolvimento e avaliação do e- Termos, um Ambiente ColaborativoWeb composto por seis módulos de trabalho bem definidos...

This paper presents the ISO 18.104:2003 as an integrative model of nursing terminology. It describes the standard, studies and experiences with its use and discusses possibilities to develop knowledge in the field. The standard has been shown to be effective in developing reference terminologies, and as a standard method for interoperability and reuse. Studies have internal limitations such as language and notations unknown to nursing. Correspondence of the model with classifications used in health services and practice is incipient, which hinders its applicability and development due to the lack of examples to be analyzed and discussed.

OBJECTIVE: Develop a knowledge-based representation for a controlled terminology of clinical information to facilitate creation, maintenance, and use of the terminology. DESIGN: The Medical Entities Dictionary (MED) is a semantic network, based on the Unified Medical Language System (UMLS), with a directed acyclic graph to represent multiple hierarchies. Terms from four hospital systems (laboratory, electrocardiography, medical records coding, and pharmacy) were added as nodes in the network. Additional knowledge about terms, added as semantic links, was used to assist in integration, harmonization, and automated classification of disparate terminologies. RESULTS: The MED contains 32,767 terms and is in active clinical use. Automated classification was successfully applied to terms for laboratory specimens, laboratory tests, and medications. One benefit of the approach has been the automated inclusion of medications into multiple pharmacologic and allergenic classes that were not present in the pharmacy system. Another benefit has been the reduction of maintenance efforts by 90%. CONCLUSION: The MED is a hybrid of terminology and knowledge. It provides domain coverage, synonymy, consistency of views, explicit relationships, and multiple classification while preventing redundancy...

Terminology work in nursing has given rise to an increasing number of nursing terminologies. These generally take the form of controlled vocabularies. Because of the limitations of the controlled vocabulary approach, individual terminologies tend to be tuned to meet the specific needs of their intended users. Differences between terminologies are now a significant barrier to the comparison and interchange of health information. To agree on a single, multipurpose terminology would be problematic. However, several options for resolving unnecessary differences between nursing terminologies are currently being explored by international standards bodies and other groups, such as the U.S. Nursing Vocabulary Summit. One such option is the use of a terminology model to facilitate evolution toward a more coherent range of terminologies. The authors describe the motivation behind the development of a standard for nursing terminologies. They explain how a terminology model might form the basis for such a standard through a description of the approach taken by CEN TC251 (the Health Informatics Technical Committee of the European Committee for Standardization). They also discuss possible limitations of standardization.

The use of a standardized controlled terminology allows diverse systems and applications throughout the enterprise to translate data. In developing a customized enterprise-wide vocabulary for clinical terminology, we implemented SNOMED CT as a base vocabulary, while facilitating the addition of site-specific clinical terms or concepts not represented in SNOMED CT. In this paper, we evaluate the breadth of SNOMED CT terms and concepts for the coding of diagnosis and problem lists by clinicians within a computerized physician order entry (CPOE) system. Clinicians selected diagnosis and problem list terms from a lexicon based on SNOMED CT, submitting requests for clinical terms that were not found in the controlled vocabulary. For each “missing” term, we assigned one of four mapping types, representing the relationship of this new terminology entry to the SNOMED CT reference terminology. Our results show that the majority of diagnosis/problem list terms (88.4%) were found in SNOMED CT. Of the 145 missing terms, only 20 represented significant concepts missing from SNOMED CT, resulting in concept coverage of 98.5%. Our results show that SNOMED CT is a relatively complete standardized terminology on which to base a vocabulary for the clinical problem list.

SNOMED CT® is a controlled medical terminology which has been licensed by the National Library of Medicine and recommended as the general terminology of choice by the National Committee on Vital and Health Statistics for the development of the electronic medical record1. Osteopathic terminology is unique to Osteopathic practitioners and must be included in any terminology if the terminology is to meet the needs of the Osteopathic community. The Authorized Osteopathic Thesaurus was used as a resource and compared with the content of SNOMED CT. It was found that a large number of concepts which were of importance in documenting Osteopathic encounters were not included in SNOMED CT. The decision was made to integrate this content into SNOMED CT.

Nanotechnology is an important, rapidly-evolving, multidisciplinary field [1]. The tremendous growth in this area necessitates the establishment of a common, open-source terminology to support the diverse biomedical applications of nanotechnology. Currently, the consensus process to define and categorize conceptual entities pertaining to nanotechnology is in a rudimentary stage. We have constructed a nanotechnology-specific conceptual hierarchy that can be utilized by end users to retrieve accurate, controlled terminology regarding emerging nanotechnology and corresponding clinical applications.

To share clinical data and to build interoperable computer systems that permit data entry, data retrieval, and data analysis, users and systems at multiple sites need a shared clinical terminology. However, local sites that adopt a shared terminology have local needs that prompt local-terminology maintainers to make changes to the local version. Meanwhile, maintainers of the shared terminology make changes to the shared version, and the two terminologies diverge. I propose a formal model for managing change, with additional features included for the local site. If terminology maintainers follow such a model, the local-terminology maintainer can synchronize the local version with the shared version at periodic intervals. I am implementing a prototype, which I will use to assess the model and to study the synchronization process.

Documentation of the administrative aspects of clinical practice (fee claims, referrals, visits etc.) is essential and a controlled terminology for the electronic health care record needs to support this requirement. The Read Codes--used in the United Kingdom for over 10 years--include a chapter of administration terms for this purpose. The latest version, the Read Thesaurus, adopts a partially compositional approach to concept representation. We describe an extension of the ENV 1828 surgical procedure scheme developed as a provisional model to represent administrative procedures. Applicable concept fields, semantic links and modifiers are identified and compared. A compositional approach appears to provide a flexible and manageable method of representing administrative procedures, and readily accommodates regional variations.

In Gastroenterology, endoscopic images and interpretation reports are essential elements of the patient record. The Digital Imaging and Communications in Medicine (DICOM) Visible Light and Structured Reporting Standards provide a standard representation of images and reports. However, the message standards are not sufficient in themselves. Controlled terminology is needed to enable interchange of patient records and to facilitate the pooling of multi-center data for large-scale outcomes studies and clinical research. The ASGE has joined with European and Japanese colleagues to develop and publish a lexicon of endoscopic terminology. The lexicon is being tested now in a multi-center trial. In addition, the ASGE is collaborating with the DICOM Standards Committee to transform the endoscopic lexicon into a database structure that is suitable for use with the DICOM Visible Light and Structured Reporting Standards. The combination of an internationally accepted, tested and non-proprietary lexical standard and a DICOM message standard supporting endoscopic images and reports represents a powerful tool for clinicians to improve communication, research and the quality of care.

A concept-based reference terminology that covers all aspects of healthcare is essential in developing the Electronic Health Record (EHR). SNOMED Clinical Terms (CT), scheduled for release in December 2001, integrates the relative strengths of SNOMED RT, and the United Kingdom s Clinical Terms Version 3, formerly known as the Read Codes Version 3. It promises to be the most comprehensive terminology available. Since a significant portion of the EHR can be drug-related information, we describe here some of the background information and rationale for the structure and scope of the merged drug hierarchy within SNOMED CT. A controlled drug terminology within a reference terminology has the potential to support a number of functions within healthcare practice. One of the functions proposed is to serve as the bridge between reference terminology and drug knowledge bases.

To maximize the value of computerized medical records systems, an organizing structure is needed. That structure can be provided by a controlled medical terminology (CMT). At Columbia-Presbyterian Medical Center, we have been employing a controlled medical terminology, our Medical Entities Dictionary (MED), to mediate the storage and retrieval of patient data and enable decision support applications. This paper describes how the MED is actually used for data management in our distributed clinical information systems environment. Our system tools which access the MED for production purposes facilitate the mapping of terms from many sources to a uniform representation of concepts and also return information about the relationships between concepts. Applications which access a CMT for production purposes should be optimized for performance in high volume settings, fault tolerant, synchronizable, extensible, portable, and maintainable. We briefly describe our system architecture and then demonstrate how we utilize the MED for translation and semantic information as data is moved into and out of our patient database. We discuss our current tools and present a preview of the next generation of applications which will manage access to the MED for our production systems.

Biomedical terminologies often contain composite concepts that cannot be translated into single unique synonymous concepts in a target controlled terminology. Such composite concepts need to be decomposed into sets of component concepts present in the target terminology that can serve as the proxy for applications in information retrieval, decision support or data analysis. Towards this goal, we use a “clustering coefficient” over the UMLS Metathesaurus to traverse the closely clustered neighbors of the composite source concept to generate a ranked list of possible component concepts. Using the MeSH Associated Expression mappings as the gold-standard, we show that the proposed approach generates relevant component concepts as compared to existing semantic locality based methods. The topological connectivity of the concepts in the UMLS Metathesaurus is a useful feature that can be coupled with existing lexical and semantic locality based approaches towards terminology translation.

It is challenging to distinguish benign from malignant thyroid nodules on high resolution ultrasound. Many ultrasound features have been studied individually as predictors for thyroid malignancy, none with a high degree of accuracy, and there is no consistent vocabulary used to describe the features. Our hypothesis is that a standard vocabulary will advance accuracy. We performed a systemic literature review and identified all the sonographic features that have been well studied in thyroid cancers. We built a controlled vocabulary for describing sonographic features and to enable us to unify data in the literature on the predictive power of each feature. We used this terminology to build a Bayesian network to predict thyroid malignancy. Our Bayesian network performed similar to or slightly better than experienced radiologists. Controlled terminology for describing thyroid radiology findings could be useful to characterize thyroid nodules and could enable decision support applications.

The radiology community has recognized the need to create a standard terminology to improve the clarity of reports, to reduce radiologist variation, to enable access to imaging information, and to improve the quality of practice. This need has recently led to the development of RadLex, a controlled terminology for radiology. The creation of RadLex has proved challenging in several respects: It has been difficult for users to peruse the large RadLex taxonomies and for curators to navigate the complex terminology structure to check it for errors and omissions. In this work, we demonstrate that the RadLex terminology can be translated into an ontology, a representation of terminologies that is both human-browsable and machine-processable. We also show that creating this ontology permits computational analysis of RadLex and enables its use in a variety of computer applications. We believe that adopting an ontology representation of RadLex will permit more widespread use of the terminology and make it easier to collect feedback from the community that will ultimately lead to improving RadLex.

Radiology reports are permanent legal documents that serve as official interpretation of imaging tests. Manual analysis of textual information contained in these reports requires significant time and effort. This study describes the development and initial evaluation of a toolkit that enables automated identification of relevant information from within these largely unstructured text reports. We developed and made publicly available a natural language processing toolkit, Information from Searching Content with an Ontology-Utilizing Toolkit (iSCOUT). Core functions are included in the following modules: the Data Loader, Header Extractor, Terminology Interface, Reviewer, and Analyzer. The toolkit enables search for specific terms and retrieval of (radiology) reports containing exact term matches as well as similar or synonymous term matches within the text of the report. The Terminology Interface is the main component of the toolkit. It allows query expansion based on synonyms from a controlled terminology (e.g., RadLex or National Cancer Institute Thesaurus [NCIT]). We evaluated iSCOUT document retrieval of radiology reports that contained liver cysts, and compared precision and recall with and without using NCIT synonyms for query expansion. iSCOUT retrieved radiology reports with documented liver cysts with a precision of 0.92 and recall of 0.96...

Randomized controlled trials (RCTs) are the centerpiece of evidence based medicine. However, because of the limited follow-up, additional evidence on the long-term consequences of the outcomes used in trials is commonly required for clinical and policy decision making. This article provides insights into the importance and challenges of using such evidence through the case study of nonfatal myocardial infarction (MI) and nonfatal bleeding with prasugrel.; C.Y.
