Objective: This study aimed to develop and validate the Salt Reduction Behavior Scale (SRBS) to measure the behavior of hypertensive Chinese individuals in adhering to salt reduction practices. Methods: The SRBS was constructed based on the Health Belief Model, consisting of five constructs: knowledge, perceived severity, perceived benefits, perceived barriers, and cues to action. Data were collected from 2,082 hypertensive patients in Beijing, China, who completed a questionnaire administered through an online platform. Kaiser-Meyer-Olkin (KMO) test was used to assess the adequacy of the sample and the Bartlett’s test of sphericity to examine the factorability of the dataset. Confirmatory Factor Analysis (CFA) was used to assess the structural validity and reliability of the SRBS. Results: The KMO analysis yielded a notably elevated value of 0.95, indicating that the data was highly suitable for Exploratory Factor Analysis (EFA). Bartlett's test of sphericity yielded a statistically significant test statistic (P < 0.001). The 32-item SRB questionnaire demonstrated strong internal consistency with a Cronbach's alpha coefficient of 0.923. A second-order Confirmatory Factor Analysis (CFA) revealed that, after removing the unrelated construct of barriers, SRB could be represented by four sub-constructs: knowledge, severity, benefits, and action. The final version of the SRBS consists of 21 items. These items displayed high factor loadings, indicating a strong relationship between the items and their respective sub-constructs. The discriminant validity analysis revealed that the SRBS sub-constructs were distinct from each other. The SRBS scores were positively correlated with self-reported salt reduction practices. This demonstrates that individuals with higher SRBS scores were more likely to engage in actual salt reduction behaviors, indicating concurrent validity. Conclusion: The results illustrate that the Salt Reduction Behavior Scale is a robust and comprehensive instrument for assessing salt reduction behavior among hypertensive Chinese individuals. The scale's specific sub-constructs provide a detailed understanding of their knowledge, attitudes, and practices related to salt consumption. Healthcare professionals and policymakers can utilize this tool to tailor interventions and educational programs to encourage healthier dietary habits, thereby reducing the risk of cardiovascular diseases in China.

新型冠状病毒肺炎(COVID-19)疫情在医院内传播的潜在风险给医护工作者及患者健康带来巨大威胁.因此,建立院感三级网络防控体系,健全相关制度措施并逐级传达落实,对于有效防控院内感染显得尤为重要.COVID-19疫情防控过程中,中国武汉各定点医院由外省多个援助队伍和本地区医务人员共同完成医疗救治工作.工作中建立了由三级网络组成的院感防控体系,该体系最高级以原医院的院级领导和各援助医疗队的领队构成,同时包含该医院原有院感管理科室和各医疗队的院感负责人;第二级为医院感染管理科,由原医院和各医疗队医院感染专职人员组成,第三级是各个病区的感控小组(包括科室负责人和护士长等).疫情期间,该体系保障医院防控工作有序进行,降低了院内感染的发生.

The mass media serves as an indispensable force in the prevention and control of epidemics, and plays a vital role in information distribution, public opinion guidance and confidence enhancement during a pandemic of infectious diseases. However, due to the particularity of infectious disease outbreaks, interview work in medical institutions should be conducted in an orderly and efficient manner under the guidance of hospital-acquired infection control and prevention protocols. This paper summarizes measures for infection control during news material collection in isolation wards from Beijing’s medical aid team to Hubei province in the fight against COVID-19, so as to provide a reference for the media to carry out relevant work on the prevention and control of infectious diseases in the future.

目的 为援助新型冠状病毒肺炎的抗疫工作,北京市卫生健康委和医院管理中心牵头组成了138人的北京市属医院援鄂医疗队(简称援鄂医疗队),前往武汉协和医院西院区参加重症患者救治工作.在工作中充分发挥医院感染防控专家作用,确保严格落实医护人员防护等医院感染防控要求.方法 援鄂医疗队到达武汉后,明确了任务,建立感染控制的规章制度,对全体队员和武汉协和医院西院区的医护人员进行了规范化流程和防护培训.用24 h的时间完成了病区的改造,建成了合理布局的"北京标准"的示范病区,并开始收治新型冠状病毒肺炎患者.在迅速开展工作的同时,加强病区和驻地的消毒,为医疗和护理安全奠定了基础.结果 援鄂医疗队连续工作50天,累计收治患者341例,其中重症患者216例,危重症患者83例,治愈142例.截至2020年3月16日,在院患者逐渐减少,床位使用率从100.00％(150/150)下降到70.67％(106/150).重症、危重症患者的比例从最高时的98.00％(147/150)下降到74.67％(112/150),治愈出院患者显著增加.实现了医护人员零感染.结论 援鄂医疗队感染控制小组在疫情防控中采取的一系列防控措施,为突发传染病疫情的防控提供了宝贵的经验.

Objective: To assist the prevention and treatment of COVID-19 in Wuhan city, Beijing municipal health commission and Beijing hospitals authority set up a medical team of 138 experts from 13 Beijing municipal hospitals, which was dispatched to Wuhan union hospital west campus to participate in the treatment of severe patients We will give full play to the role of hospital infection prevention and control experts in our work and ensure the strict implementation of hospital infection prevention and control requirements such as the protection of medical staff Methods: After arriving in Wuhan, Beijing aid medical team of Hubei province defined the mission, established the rules and regulations for infection control, and conducted standardized procedures and protection training for all the team members and the medical staff in the west hospital of Wuhan union hospital It took 24hours to complete the transformation of the ward, build a reasonable layout of the demonstration ward of Beijing standard, and start the treatment of COVID-19 confirmed patients While the work was carried out rapidly, the disinfection of the ward and residence was strengthened, which laid the foundation for medical and nursing safety Results: At present, the medical team has been working continuously for 50 days, receiving and treating 341patients including 216 severe patients, 83 critically ill patients and 142 cured At present, the number of patients in the hospital is gradually decreasing, with the utilization rate of beds dropping from 100 00% (150/150) to 70 67% (106/150) The proportion of critically ill patients dropped from a peak of 98 00% (147/150) to 74 67% (112/150), and the number of patients cured and discharged increased significantly Zero infection was achieved for all health care workers Conclusion: This paper summarizes a series of prevention and control measures taken by the infection control team during the work in prevention and control of Novel coronavirus pneumonia in Wuhan union hospital west campus, which provides a reference for the prevention and control of the outbreak of infectious diseases
