SARS-CoV-2的爆发使我们所有人都对医院室内空气质量以及从医院环境中去除、稀释和消毒致病微生物的方法进行了批判性思考。虽然冠状病毒的传染性、传播和传播途径的具体方面仍在严格调查中，但回顾文献中的知识似乎可以为应对这一新形势提供有用的经验教训。因此，对医疗场所空气过滤和空气再循环的安全性进行了系统的文献综述。这次审查的目标是广泛的证据，从守则和条例，到同行评议的出版物和最佳实践标准。文献检索结果为394份出版物，其中109份文献被纳入最终审评。总体而言，尽管支持目前做法的确凿证据非常少，但适当的过滤仍然是保持医院室内空气清洁度的重要方法。考虑到过滤系统的物理足迹相当大，从文献中收集了一系列短期和长期解决方案。尽管如此，在卫生保健设施的空气过滤和再循环领域，仍需要进行严格和可行的研究。这种努力可以在正常情况下或大流行期间提高卫生保健设施的绩效。过去的创新可以以低至最低的成本用于新的疫情。
The outbreak of SARS-CoV-2 has made us all think critically about hospital indoor air quality and the approaches to remove, dilute, and disinfect pathogenic organisms from the hospital environment. While specific aspects of the coronavirus infectivity, spread, and routes of transmission are still under rigorous investigation, it seems that a recollection of knowledge from the literature can provide useful lessons to cope with this new situation. As a result, a systematic literature review was conducted on the safety of air filtration and air recirculation in healthcare premises. This review targeted a wide range of evidence from codes and regulations, to peer-reviewed publications, and best practice standards. The literature search resulted in 394 publications, of which 109 documents were included in the final review. Overall, even though solid evidence to support current practice is very scarce, proper filtration remains one important approach to maintain the cleanliness of indoor air in hospitals. Given the rather large physical footprint of the filtration system, a range of short-term and long-term solutions from the literature are collected. Nonetheless, there is a need for a rigorous and feasible line of research in the area of air filtration and recirculation in healthcare facilities. Such efforts can enhance the performance of healthcare facilities under normal conditions or during a pandemic. Past innovations can be adopted for the new outbreak at low-to-minimal cost.
