A survey of 173 dental staff was conducted in February–March 2023. The rates of incidents caused by contact with blood and their nature among dental staff were determined, and the frequency of correctly performed algorithm of actions during an incident was calculated. The frequency of the implementation of measures for the prevention of occupational infections with blood-borne pathogens was estimated. Categorical data were described as absolute values and proportions (%).</p> <p><bold><italic>RESULTS</italic></bold><italic>:</italic> In total, 65 specialists (37.6%) had encountered incidents such as contact with blood at the workplace. These incidents were significantly more common among women than among men: 44.7% (55/123) vs. 20.0% (10/50), respectively (<italic>p</italic>=0.002). The last incident in 50 respondents was associated with skin damage (needlestick injury or cut exposure); in 17 participants, their mucous membranes were exposed to blood (including two people with a mixed characteristic of incident: skin damage + exposure of their mucous membranes to blood). After contact with blood, local treatment was carried out correctly (according to Russian recommendations) in 18.0% of the participants with skin damage and 70.5% with blood exposure to mucous membranes. After the incident, 58.5% of the participants (38/65) reported to the head of the department or clinic, and a third of the respondents (23/65, 35.4%) recorded a case of contact with blood in the incident log. Nearly all respondents always use gloves (172/173, 99.4%) when they work in the dental office. Moreover, 64.2% of the respondents (111/173) always use safety glasses or screens. Nine respondents (9/173, 5.2%) do not use personal eye protection. Others (53/173, 30.6%) wear safety glasses/screens only when performing certain procedures. In addition, 85.0% (147/173) of the respondents have been vaccinated against HBV, 18 have not been vaccinated (10.4%), and 8 (4.6%) do not know their vaccination status.</p> <p><bold><italic>CONCLUSIONS</italic></bold><italic>:</italic> The results of this study present the necessity of raising awareness among dental staff regarding the epidemiology and prevention of blood-borne infections to reduce the risk of occupational infections.</p></abstract><trans-abstract xml:lang="ru"><p><bold>Обоснование</bold>. Осведомлённость работников стоматологического профиля об эпидемиологии гемоконтактных инфекций (ВИЧ-инфекции, гепатитов В и С), а также знание алгоритма действий в случае аварийной ситуации на рабочем месте являются ключевым звеном в профилактике профессионального заражения данными заболеваниями.</p> <p>Цель исследования — оценка информированности персонала стоматологического профиля о соблюдении алгоритма постэкспозиционной профилактики профессионального заражения гемоконтактными инфекциями и приверженности ему.</p> <p><bold>Материалы и методы</bold>. Выполнено наблюдательное многоцентровое одномоментное выборочное неконтролируемое исследование. Объекты исследования — медицинский персонал государственных и частных клиник стоматологического профиля г. Казани. Проведено анкетирование медицинского персонала в феврале–марте 2023 года (<italic>n</italic>=173). Определены доля аварийных ситуаций и их характер среди специалистов стоматологического профиля, а также рассчитана частота правильно выполненного алгоритма действий при возникновении аварийной ситуации. Оценена частота реализации мер по профилактике профессионального заражения гемоконтактными инфекциями. Категориальные данные были описаны с указанием абсолютных значений и процентных долей (%).</p> <p><bold>Результаты</bold>. Аварийные ситуации на рабочем месте встречались у 65 специалистов (65/173, 37,6%). Аварийные ситуации значимо чаще встречались среди женщин, чем среди мужчин: 44,7% (55/123) против 20,0%(10/50) соответственно (<italic>р</italic>=0,002). Последняя аварийная ситуация у 50 человек была связана с повреждением кожи (проколы или порезы), у 17 — с попаданием крови на слизистые оболочки (включая 2 человек со смешанным характером аварийной ситуации: повреждение кожи + попадание крови на слизистые). Местную обработку после аварийной ситуации правильно (согласно требуемому СанПиНом алгоритму) провели 18,0% при повреждении кожных покровов, 70,5% — при попадании крови на слизистые. После последней аварийной ситуации руководство оповестили чуть больше половины специалистов (38/65, 58,5%), запись в журнал регистрации аварийных ситуаций произвели треть опрошенных (23/65, 35,4%). При работе в стоматологическом кабинете почти все специалисты всегда используют перчатки (172/173, 99,4%). В отношении использования защитных очков или экранов всегда их используют 64,2% медицинских работников стоматологического профиля (111/173), не используют средства индивидуальной защиты глаз 9 человек (9/173, 5,2%). Остальные (53/173, 30,6%) надевают защитные очки / экраны только при выполнении определённых процедур. Большинство респондентов (147/173, 85,0%) вакцинированы против вирусного гепатита B, не привито 18 человек (18/173, 10,4%), 8 человек (8/173, 4,6%) не знают свой прививочный статус.</p> <p><bold>Заключение</bold>. Продемонстрирована необходимость повышения информированности специалистов стоматологических организаций в области эпидемиологии и профилактики гемоконтактных инфекций с целью снижения риска профессионального заражения этими инфекциями.</p></trans-abstract><kwd-group xml:lang="en"><kwd>blood-borne pathogens</kwd><kwd>risk factors</kwd><kwd>occupational exposure</kwd><kwd>protective clothing</kwd><kwd>infection control</kwd><kwd>needlestick injuries</kwd></kwd-group><kwd-group xml:lang="ru"><kwd>гемоконтактные инфекции</kwd><kwd>факторы риска</kwd><kwd>профессиональное воздействие</kwd><kwd>средства индивидуальной защиты</kwd><kwd>инфекционный контроль</kwd><kwd>аварийная ситуация</kwd></kwd-group><funding-group/></article-meta></front><body></body><back><ref-list><ref id="B1"><label>1.</label><citation-alternatives><mixed-citation xml:lang="en">Ayatollahi J, Ayatollahi F, Ardekani AM, et al.
