Разработать и валидировать модель машинного обучения, предназначенную для выявления подозрения на тромбоэмболию легочной артерии (ТЭЛА) по различным клиническим признакам из электронных медицинских карт (ЭМК) пациентов, обращающихся за амбулаторной и стационарной помощью.</p></sec><sec><title>Материал и методы</title><p>Материал и методы. Данные 19730 пациентов из 7 регионов Российской Федерации были взяты для анализа. Период накопления данных ЭМК: с 21.03.2007 по 04.02.2022. В качестве диагностических признаков использованы жалобы, клинические признаки, результаты лабораторных исследований, сопутствующие заболевания. У 1379 пациентов была диагностирована ТЭЛА. Диагностика ТЭЛА была на основании кодов МКБ-10 в заключительном диагнозе случая лечения. Было применено 7 алгоритмов машинного обучения для выполнения задачи диагностики ТЭЛА: XGBoost, LightGBM, CatBoost, Logistic Regression, MLP Classifier, Random Forest Classifier, Gradient Boosting Classifier.</p></sec><sec><title>Результаты</title><p>Результаты. Модель на основе алгоритма Gradient Boosting Classifier была выбрана для дальнейшей проспективной апробации: чувствительность 0,899 (95% доверительный интервал (ДИ): 0,864-0,932), специфичность 0,875 (95% ДИ: 0,863-0,86), площадь под ROC-кривой 0,952 (95% ДИ: 0,938-0,964). Наибольшую значимость для предсказания имели признаки: кашель, дыхательные нарушения, креатинин крови, температура тела, общая слабость, частота сердечных сокращений, частота дыхания, отеки, антигипертензивная терапия, сатурация и возраст.</p></sec><sec><title>Заключение</title><p>Заключение. Обученная модель рассчитана для использования при первичном обращении за медицинской помощью пациентов с жалобами и подозрением на ТЭЛА вне зависимости от вида помощи.</p></sec></abstract><trans-abstract xml:lang="en"><sec><title>Aim</title><p>Aim. To develop and validate a machine learning model designed to identify suspected pulmonary embolism (PE) based on various clinical features from electronic health records (EHRs) of out- and inpatients.</p></sec><sec><title>Material and methods</title><p>Material and methods. Data from 19730 patients from 7 Russian regions were taken for analysis. EHR data were analyzed for the period from March 21, 2007 to February 4, 2022. Complaints, clinical and laboratory data, and concomitant diseases were used as diagnostic signs. PE was diagnosed in 1379 patients. Diagnosis of PE was based on ICD-10 codes. Seven machine learning algorithms were applied to diagnose pulmonary embolism: XGBoost, LightGBM, CatBoost, Logistic Regression, MLP Classifier, Random Forest Classifier, Gradient Boosting Classifier.</p></sec><sec><title>Results</title><p>Results. The Gradient Boosting Classifier-based model was selected for further prospective testing with the sensitivity of 0,899 (95% confidence interval (CI), 0,864-0,932), specificity of 0,875 (95% CI, 0,863-0,86), area under the ROC curve of 0,952 (95% CI, 0,938-0,964). The following signs had the greatest prediction value: cough, respiratory disorders, blood creatinine, body temperature, general weakness, heart rate, respiratory rate, edema, antihypertensive therapy, saturation and age.</p></sec><sec><title>Conclusion</title><p>Conclusion. The model is designed for the initial encounter of patients with complaints and suspected PE, regardless of the type of care.</p></sec></trans-abstract><kwd-group xml:lang="ru"><kwd>тромбоэмболия легочной артерии</kwd><kwd>электронные медицинские карты</kwd><kwd>машинное обучение</kwd><kwd>система поддержки клинических решений</kwd></kwd-group><kwd-group xml:lang="en"><kwd>pulmonary embolism</kwd><kwd>electronic health records</kwd><kwd>machine learning</kwd><kwd>clinical decision support system</kwd></kwd-group></article-meta></front><back><ref-list><title>References</title><ref id="cit1"><label>1</label><citation-alternatives><mixed-citation xml:lang="ru">Raskob GE, Angchaisuksiri P, Blanco AN, et al.
