The assessment of physicians' and senior medical students’ knowledge in the field of communityacquired pneumonia: preliminary results of the KNOCAP-II project (2017-2019)

Внебольничная пневмония (ВП) относится к одной из самых актуальных проблем современной медицины. На сегодняшний день ВП занимает 4 место в структуре смертности (после сердечно-сосудистых, цереброваскулярных заболеваний и злокачественных новообразований) и 1 место среди всех смертей от инфекционных заболеваний. Цель – оценка уровня знаний врачей терапевтического профиля и студентов старших курсов медицинских вузов в вопросах ведения пациентов с ВП. В рамках многоцентрового исследования KNOCAP (полное название проекта – «The assessment of physician and students’ knowledge of community-acquired pneumonia basics») представлены результаты анонимного проспективного опроса по оценке знаний и предпочтений врачей терапевтического профиля и студентов старших медицинских курсов в вопросах ведения пациентов с ВП. По итогам первого периода проекта (2017-2019 гг.) получены и проанализированы результаты анкетирования 588 врачей терапевтического профиля и 394 студентов-медиков из 17 центров России, Украины и Кыргызстана. За основу взят метод анонимного анкетирования, для чего была разработана оригинальная анкета на основании актуальных клинических рекомендаций. Наибольшие сложности вызвали следующие вопросы: сроки проведения повторного рентгенологического исследования при положительной динамике лечения, выбор основного диагностического признака при ведении пациента с ВП, указать типовые ошибки фармакотерапии ВП и выбор стартовой антимикробной терапии у пациентов с факторами риска и без них. В целом исследование показало значимое несоответствие знаний в вопросах ведения пациентов с ВП актуальным клиническим рекомендациям 2010 г. и проектом новых клинических рекомендаций 2018-2019 гг. В настоящее время существует необходимость в повышении уровня знаний и совершенствовании профессиональной деятельности врачей терапевтического профиля и студентов старших медицинских курсов, так как проведенный многоцентровой срез знаний и предпочтений специалистов во многих вопросах выявил их недостаточный уровень для корректного ведения пациентов с ВП. Community-acquired pneumonia (CAP) is one of the most relevant problems of modern medicine. Today, CAP takes 4th place in the structure of mortality (after cardiovascular, cerebrovascular diseases and malignant neoplasms) and 1st place among all deaths from infectious diseases. The aim of the study is to assess the level of general physician’ and senior medical students’ basic knowledge in CAP treatment. The article represents the results of anonymous prospective surveys within the framework of the second stage of KNOCAP multi-centered research project (full name of the project «The assessment of physician’ and students’ knowledge of community-acquired pneumonia basics») aimed at accessing the knowledge and preferences of doctors and students on the fundamental issues in diagnosis and treatment of community-acquired pneumonia. The survey conducted in 2017-2019 involved 588 physicians and 394 students from seventeen Russian, Kyrgyzstan and Ukrainian centers. The method of anonymous questioning was used in this study, for which an original questionnaire was developed on the basis of current clinical recommendations. The following fundamental questions caused the greatest difficulties in the respondents: terms for a repeated X-ray examination in positive dynamics of CAP treatment, the choice of main diagnostic criteria of CAP, the choice of the typical mistakes of CAP treatment, the choice of the initial antimicrobial therapy. In general, the respondents’ knowledge in CAP patients’ management deviates significantly from the current clinical guidelines, as of 2010, and from the new clinical guidelines draft, 2018-2019. Currently, there is a need to increase the level of knowledge and improve the professional activities of therapists and senior medical students, as a multicenter section of the knowledge and preferences of specialists in many issues revealed their insufficient level for the correct management of patients with CAP

Development of Hydrogeological Modelling Approaches for Assessment of Consequences of Hazardous Accidents at Nuclear Power Plants

This paper introduces some modeling approaches for predicting the influence of hazardous accidents at nuclear reactors on groundwater quality. Possible pathways for radioactive releases from nuclear power plants were considered to conceptualize boundary conditions for solving the subsurface radionuclides transport problems. Some approaches to incorporate physical-and-chemical interactions into transport simulators have been developed. The hydrogeological forecasts were based on numerical and semi-analytical scale-dependent models. They have been applied to assess the possible impact of the nuclear power plants designed in Russia on groundwater reservoirs

Development of Analytical and Numerical Models for the Assessment and Interpretation of Hydrogeological Field Tests

Mathematical models of the flow and tracer tests in fractured aquifers are being developed for the further study of radioactive wastes migration in round water at the Lake Area, which is associated with one of the waste disposal site in Russia. The choice of testing methods, tracer types (chemical or thermal) and the appropriate models are determined by the nature of the ongoing ground-water pollution processes and the hydrogeological features of the site under consideration. Special importance is attached to the increased density of wastes as well as to the possible redistribution of solutes both in the liquid phase and in the absorbed state (largely, on fracture surfaces). This allows for studying physical-and-chemical (hydrogeochemical) interaction parameters which are hard to obtain (considering a fractured structure of the rock mass) in laboratory. Moreover, a theoretical substantiation is being given to the field methods of studying the properties of a fractured stratum aimed at the further construction of the drainage system or the subsurface flow barrier (cutoff wall), as well as the monitoring system that will evaluate the reliability of these ground-water protection measures. The proposed mathematical models are based on a tight combination of analytical and numerical methods, the former being preferred in solving the principal (2D axisymmetrical) class of the problems. The choice of appropriate problems is based on the close feedback with subsequent field tests in the Lake Area. 63 refs
