Survey data on the administration of nosocomial Infection in dental clinics in Dandong City

According to the World Health Organization, many common respiratory infections continue to have high morbidity and mortality rates every year. Unlike other departments, operations in dental clinics using special instruments (mainly including high-speed turbine handpieces and ultrasonic scalers) can eject large quantities of water mist and aerosols, many of which are pathogenic, e.g. coronaviruses, tuberculosis, measles viruses, herpes simplex viruses, which can survive in the air for hours. What's more, during treatment, patients cannot wear masks and most pathogens can reach the patient's alveoli directly through the respiratory tract. In order to find more appropriate ways to control the source of infection, cut off transmission routes and protect susceptible populations, it is necessary to investigate the current status of respiratory infection prevention and control measures in dental clinics. Therefore, in January and February 2023, we conducted a sample survey of prevention and control management in dental clinics in Dandong, Liaoning Province, China. A multistage stratified equivocal volumetric random sampling method was used to select 30 dental clinics in Dandong City, Liaoning Province, China, that had a medical institution licence and were equipped with two or more comprehensive dental treatment units. In the first stage, Zhenxing District and Yuanbao District were selected for the survey. In the second stage, we selected 15 streets with dental clinics in each area. In the third stage, one dental clinic equipped with more than two comprehensive dental treatment units and cooperating with the survey was randomly selected from each street.

据世界卫生组织（World Health Organization）统计，多种常见呼吸道传染病每年仍维持较高的发病率与死亡率水平。与其他临床科室不同，牙科门诊在使用特殊器械（主要包括高速涡轮手机与超声洁牙机）开展诊疗操作时，会产生大量水雾和气溶胶，其中不少携带有致病微生物，例如冠状病毒、结核分枝杆菌、麻疹病毒、单纯疱疹病毒，此类气溶胶可在空气中存活数小时。此外，诊疗过程中患者无法佩戴口罩，且多数致病微生物可经呼吸道直接抵达患者肺泡。为探索更为科学适宜的感染源头管控、传播途径切断及易感人群保护策略，亟需开展牙科门诊呼吸道传染病防控措施现状调研。为此，本研究于2023年1月至2月，针对中国辽宁省丹东市的牙科门诊防控管理现状开展抽样调查。本研究采用多阶段分层等容积随机抽样方法，从丹东市范围内筛选出30家持有《医疗机构执业许可证》且配备2台及以上综合牙科治疗台的牙科门诊作为调查对象：第一阶段，选取振兴区与元宝区作为调研覆盖区域；第二阶段，在上述两个区域内各遴选15家设有牙科门诊的街道；第三阶段，从每条街道中随机抽取1家配备2台及以上综合牙科治疗台且同意配合调研的牙科门诊。
