Поскольку нежелательные явления, как правило, описываются в медицинских записях в виде свободного текста, для извлечения информации о них из десятков тысяч историй болезни требуются специальные технологии.</p><sec><title>ЦЕЛЬ ИССЛЕДОВАНИЯ</title><p>ЦЕЛЬ ИССЛЕДОВАНИЯ: оценить качество предложенного нами алгоритма для полуавтоматической идентификации парезов у пациентов с глиальными опухолями на этапе поступления в нейрохирургический стационар.</p></sec><sec><title>МАТЕРИАЛЫ И МЕТОДЫ</title><p>МАТЕРИАЛЫ И МЕТОДЫ: Для решения данной задачи был применен разработанный нами комплекс технологий с использованием методов искусственного интеллекта (патент RU 2751993C 1). В основе метода лежит отбор специфического для конкретного нежелательного явления лексикона и расшифровка его использования в микроконтекстах. Проанализированы текстовые медицинские записи, первично внесенные врачами с помощью клавиатуры в электронную медицинскую карту «E-med» ФГАУ «НМИЦ нейрохирургии им. ак. Н. Н. Бурденко» Минздрава России в период с 2000 г. по 2017 г.</p></sec><sec><title>РЕЗУЛЬТАТЫ</title><p>РЕЗУЛЬТАТЫ. Предложенный нами алгоритм позволил выявить парезы на дооперационном этапе с высоким качеством (чувствительность = 0,947, специфичность = 0,965, точность = 0,961, F1-мера = 0,926, ROC AUC = 0,956 [0,941; 0,969]). За счет оптимизации предложенного нами способа (использования только существительных при скрининге словаря) удалось сократить время на его реализацию c 13 до 6 часов практически без потери качества.</p></sec><sec><title>ЗАКЛЮЧЕНИЕ</title><p>ЗАКЛЮЧЕНИЕ. Методы анализа текстов, написанных на естественном языке, позволяют улучшить качество извлечения информации из медицинских текстов, что, в частности, может быть успешно применено в исследованиях безопасности оказания нейрохирургической помощи.</p></sec></abstract><trans-abstract xml:lang="en"><p>Adverse events identiﬁcation in clinical documents is necessary for retrospective clinical research and evaluating medical care safety and cost-effectiveness. Since adverse events are usually reported with free text in medical records, special technologies are required to extract information about them from thousands of medical records.</p><sec><title>MATERIALS AND METHODS</title><p>MATERIALS AND METHODS: We introduced a technology to extract information based on natural language processing (patent RU 2751993C 1). The method is grounded on preselecting a lexicon speciﬁc to a particular adverse event and deciphering its use in microcontexts. The textual medical records, initially typed in by doctors using the keyboard into the electronic health records system «E-med» of the FSAI «NMRC named after ac. N. N. Burdenko» of the ministry of health of Russia from 2000 to 2017 were analysed.</p></sec><sec><title>RESULTS</title><p>RESULTS. The technology we proposed enabled us to solve the task of paresis identiﬁcation with high quality (sensitivity = 0,947, speciﬁcity = 0,965, accuracy = 0,961, F1-score = 0,926, ROC AUC = 0,956 [0,941; 0,969]). Optimization of the proposed method (using only nouns when screening a vocabulary) enabled to reduce the time for its implementation from 13 to 6 hours with no major loss in quality.</p></sec><sec><title>CONCLUSION</title><p>CONCLUSION. Natural language processing can improve the quality of information extraction from medical texts, which, in particular, can be successfully applied in neurosurgical safety research.</p></sec></trans-abstract><kwd-group xml:lang="ru"><kwd>нейрохирургия</kwd><kwd>тромбоэмболия легочной артерии</kwd><kwd>осложнения</kwd><kwd>искусственный интеллект</kwd><kwd>анализ текстов на естественном языке</kwd></kwd-group><kwd-group xml:lang="en"><kwd>neurosurgery</kwd><kwd>paresis</kwd><kwd>complications</kwd><kwd>artiﬁcial intelligence</kwd><kwd>natural language processing</kwd></kwd-group><funding-group><funding-statement xml:lang="ru">Проект поддержан грантом РФФИ 18-29-22085.
