概括
面罩强制有效地减少了SARS-CoV-2的繁殖数量,增加了面罩的使用. 然而,单独授权并没有显著降低COVID-19病例增长率,突显了控制大流行病的综合战略的必要性.
科学领域:
- 流行病学 流行病学
- 公共卫生政策 公共卫生政策
- 传染病控制和控制传染病
背景情况:
- 面罩在预防急性呼吸道感染 (包括COVID-19) 的有效性仍然是一个关键的公共卫生问题.
- 现有的随机对照试验提供了有限的真实世界的证据,对面具的实用性.
- 需要高的外部有效性数据来为公共卫生干预提供信息.
研究的目的:
- 评估口罩授权和建议对自我报告的口罩使用的影响.
- 评估这些政策对SARS-CoV-2繁殖数量和COVID-19病例增长率的影响.
- 为非药物干预措施的有效性提供现实世界的证据.
主要方法:
- 采用事件研究方法,使用来自多个来源的聚合数据.
- 数据包括自我报告的口罩使用 (COVID-19趋势和影响调查),政府响应追踪器 (牛津COVID-19政府响应追踪器),移动数据 (谷歌社区移动报告) 和流行病学数据 (我们的世界数据).
- 分析的重点是51个国家的口罩任务和10个国家的建议.
主要成果:
- 面具要求显著增加了自我报告的面具使用量8.81个百分点,并平均减少了SARS-CoV-2的繁殖数量-0.31个单位.
- 虽然任务显示26天后COVID-19病例增长率的增量影响,但它们没有产生显著的平均减少.
- 面具推也增加了自我报告的面具使用,但对生殖数量和病例增长率的影响有限.
结论:
- 面具强制是减少SARS-CoV-2传播的有效策略,这是减少生殖数量的证据.
- 单靠授权就不足以制COVID-19病例增长率,这表明需要采取补充措施.
- 这项研究增强了现有关于面罩在现实环境中的有效性研究的外部有效性.

Transmission-based Precautions II: Airborne and Protective Environment
1.3K
Transmission-based precautions are for patients infected or suspected to be infected (or colonized) with organisms posing a significant risk to others. The transmission precautions include airborne and protective environment precautions.
Airborne precautions:
Use airborne precautions when treating patients known or suspected to have diseases that spread through the air—for example, tuberculosis or measles. These organisms are present in smaller droplets expelled by an infected person and...

PPE Use in Healthcare Settings II: Doffing
906
The sequence of removing or doffing PPE starts with the gloves, as they are the most contaminated. Next is removal of the face shield or goggles, as they would interfere with removing other PPE. Then remove the gown, followed by the mask or respirator. Perform hand hygiene between steps if hands become contaminated and immediately after removing all PPE. Generally, the outside front and sleeves of the isolation gown, the goggles or the mask, the respirator, and the face shield are contaminated.

Facial Feedback Hypothesis
152
Charles Darwin proposed that facial expressions are an evolutionary adaptation for communication. He argued that these expressions are not influenced by culture but are universal across species. For example, a snarling expression with exposed teeth signals a threat in many animals, including humans. Darwin also suggested that displaying an emotion can intensify the feeling. Smiling, for example, could enhance one's sense of happiness. This idea laid the foundation for understanding the role...

PPE Use in Healthcare Settings I: Donning
962
Donning PPE must be completed before contact with the patient. This process protects from infectious agents. The sequence and action included in each donning are critical, and the steps must be systematic to avoid exposure to pathogens. The institutional policy also needs to be followed while donning PPE. The pre-donning preparations are gathering equipment, inspecting the PPE equipment for tears, holes, or damage, removing jewelry, removing any garments below the elbows, and tying the hair...

Personal Protective Equipment
1.5K
Personal protective equipment (PPE) is unique clothing or equipment worn by an employee to minimize or prevent exposure to infectious agents. PPE creates a barrier between the employee and the infectious materials. PPE must be readily available in the patient care area. PPE includes gloves, gowns and aprons, masks and respirators, goggles, face shields, shoes, and headcovers:
