概括

在老年护理机构的一般隔离使COVID-19病例在没有查的情况下减少了27%,但在查和病例隔离的情况下只减少了12%. 这表明隔离政策在与其他干预措施相结合时提供有限的额外好处.

科学领域:

流行病学流行病学
传染病建模传染病建模
公共卫生干预公共卫生干预

背景情况:

住宅老年护理设施 (RACF) 是呼吸道感染的高风险环境.
在COVID-19期间,社会隔离政策被广泛使用,但其有效性仍在争论中.
人们担心一般隔离对居民的负面健康影响.

研究的目的:

在COVID-19期间模拟RACF中一般隔离政策的有效性.
评估居民社会隔离的边际影响,无论感染状况如何.
将隔离策略与其他常见干预措施进行比较.

主要方法:

在住院护理环境中开发了基于代理的COVID-19传播模型.
模拟了各种各样的疫情情情景,采用不同的缓解策略.
包括一般居民隔离,病例隔离,员工休假和个人防护设备部署.

主要成果:

在没有无症状查的情况下,一般隔离减少了27%的累计病例中位数.
随着无症状查和病例隔离,一般隔离的益处降至12%.
一般隔离的有效性对有关居民接触模式的假设敏感.

结论:

一般居民隔离在RACF中除了查和病例隔离之外,提供了最小的额外好处.
有效的病例隔离和无症状查对于控制疫情至关重要.
这些发现强调了在老年护理感染控制方面需要基于证据的战略.

Healthcare Associated Infections II: Preventive Measures

Essential infection prevention measures are based on the knowledge of the infection chain, the modes of transmission in healthcare settings, and the use of the best practices in all healthcare settings. Compulsory public reporting of healthcare-associated infection rates is needed to allow individuals and the community to make informed choices regarding selecting a healthcare facility.
The best practices for preventing healthcare-associated infections include hand hygiene, patient risk...
