The language of medical reports and its information-lexical analysis

Cílem disertační práce byla informačně lexikální analýza českých lékařských zpráv a využitelnost mezinárodních klasifikačních systému v českém zdravotnickém prostředí. Analýza lékařských zpráv byla založena na atributech Minimálního datového modelu pro kardiologii (MDMK). Byly použity lékařské zprávy psané volným textem a strukturované lékařské zprávy uložené v softwarové aplikaci ADAMEK. Pro práci byly využity zejména klasifikační systémy SNOMED CT a MKN-10. Bylo porovnáno, jak dobře jsou atributy MDMK zaznamenány v textových lékařských zprávách a v lékařských zprávách zaznamenávaných strukturovaně pomocí softwarové aplikace ADAMEK. Byla provedena jazyková analýza českých textových lékařských zpráv. Byla navržena nová aplikace metod pro měření diverzity lékařských zpráv psaných v jakémkoli jazyce. Tato nová aplikace je založena na obecných konceptech diverzit a byla odvozena z f-diverzity, relativní f-diverzity, vlastní f-diverzity a marginální f- diverzity. Závěrem práce je zjištění, že zapisování lékařských zpráv formou volného textu je velice nesourodé a není standardizováno. Použití standardizované terminologie by přineslo výhody lékařům, pacientům, administrátorům, softwarovým vývojářů a plátcům a pomohlo by poskytovatelům zdravotnické péče tím, že by poskytovalo kompletní a snadno dostupné...The objective of the dissertation thesis has been the information-lexical analysis of Czech medical reports and the usability of international classification systems in the Czech healthcare environment. The analysis of medical reports has been based on the attributes of the Minimal Data Model for Cardiology (MDMC). Narrative medical reports and structured medical reports from the ADAMEK software application have been used. For the thesis SNOMED CT and ICD-10 classification systems have been used. There has been compared how well attributes of MDMC are recorded in narrative and structured medical reports. The language analysis of the Czech narrative medical reports has been made. A new application for measuring diversity in medical reports written in any language is proposed. The application is based on the general concepts of diversities derived from f-diversity, relative f- diversity, self f-diversity and marginal f-diversity. The thesis has come to the conclusion that using a free text in medical reports is not consistent and not standardized. The standardized terminology would bring benefits to physicians, patients, administrators, software developers and payers and it would help healthcare providers as it could provide complete and easily accessible information that belongs to the process of...First Faculty of Medicine1. lékařská fakult

Measuring diversity in medical reports based on categorized attributes and international classification systems

<p>Abstract</p> <p>Background</p> <p>Narrative medical reports do not use standardized terminology and often bring insufficient information for statistical processing and medical decision making. Objectives of the paper are to propose a method for measuring diversity in medical reports written in any language, to compare diversities in narrative and structured medical reports and to map attributes and terms to selected classification systems.</p> <p>Methods</p> <p>A new method based on a general concept of f-diversity is proposed for measuring diversity of medical reports in any language. The method is based on categorized attributes recorded in narrative or structured medical reports and on international classification systems. Values of categories are expressed by terms. Using SNOMED CT and ICD 10 we are mapping attributes and terms to predefined codes. We use f-diversities of Gini-Simpson and Number of Categories types to compare diversities of narrative and structured medical reports. The comparison is based on attributes selected from the Minimal Data Model for Cardiology (MDMC).</p> <p>Results</p> <p>We compared diversities of 110 Czech narrative medical reports and 1119 Czech structured medical reports. Selected categorized attributes of MDMC had mostly different numbers of categories and used different terms in narrative and structured reports. We found more than 60% of MDMC attributes in SNOMED CT. We showed that attributes in narrative medical reports had greater diversity than the same attributes in structured medical reports. Further, we replaced each value of category (term) used for attributes in narrative medical reports by the closest term and the category used in MDMC for structured medical reports. We found that relative Gini-Simpson diversities in structured medical reports were significantly smaller than those in narrative medical reports except the "Allergy" attribute.</p> <p>Conclusions</p> <p>Terminology in narrative medical reports is not standardized. Therefore it is nearly impossible to map values of attributes (terms) to codes of known classification systems. A high diversity in narrative medical reports terminology leads to more difficult computer processing than in structured medical reports and some information may be lost during this process. Setting a standardized terminology would help healthcare providers to have complete and easily accessible information about patients that would result in better healthcare.</p

Usage of International Nomenclatures and Metathesauruses in Shared Healthcare in the Czech Republic

The article describes various metathesauruses and international nomenclatures used in health care. The focus is on the Unified Medical Language System, especially UMLS Metathesaurus. In our work we try to verify practical applicability of internationally used terminologies, thesauruses, ontologies, and classifications in attributes of the Minimal Data Model for Cardiology, in the Data Standard of Ministry of Health CR, and in several chosen modules of commercial hospital information systems

The International Classification of Diseases and its use in the Minimal Data Model for Cardiology

The paper describes the International Classification of Diseases (ICD), its history, contents and organization. The paper focuses also on the Minimal Data Model for Cardiology and utilization of ICD in this model. Finally, it focuses on the possibility of SNOMED CT and ICD version 10 classification systems for semantic interoperability in the Czech language environment

SPECIALIST Lexicon and the Czech Language

The article focuses on the SPECIALIST lexicon, one of three UMLS knowledge sources. Its aim is to create a general English lexicon containing many biomedical terms. Each entry in the lexicon describes syntactic, morphologic, and orthographic information needed for natural language processing. As there is no such a lexicon for the Czech language, the article describes also the analysis of the Czech language that could help in integrating Czech to the lexicon
