“…In the study by Wang et al [21], there was a SARS-CoV-2 patient present in each family but there was no record of the amount of virus being emitted by the index case. Similarly, in the study by Guedes et al [20], there was no record of the infectiousness of the index cases nor whether clusters were all derived from a single infector (there was no sequencing) or just a number of non-associated infections from the community; there were also multiple NPIs applied in these settings. In all three studies, ventilation was one of several different factors considered and although no significant association was found between the presence of a ventilation system and COVID-19 outcomes confidence in all these studies is weak, which is borne out in the GRADE ROBINS-I analysis, tables 2 and 3.…”

“…For a detailed description of the number of references at each stage, see the Prisma flowchart in figure 1. Overall, the 19 studies included here provide evidence for the effectiveness (or ineffectiveness) of the following NPIs: ventilation (n=12) [10–21]; air filtration/air cleaning devices (n=4) [17,26–28]; surface disinfection (n=5) [20–24]; room occupancy (n=6) [11,12,16,24–26]; and screens/barriers (n=1) [17]. No evidence was found on the use of normalCO2 monitoring or one-way systems in reducing transmission.…”

“…No evidence was found on the use of normalCO2 monitoring or one-way systems in reducing transmission. These 19 studies covered a range of settings: healthcare facilities (n=6) [18, 20,22–24]; residential ( n =3) [10,11,21]; meat-processing plants (n=2) [12,14]; school classrooms (n=2) [16,17]; an overnight camp (n=1) [25]; a bus (n=1) [13]; a restaurant (n=1) [26]; and an oilfield (n=1) [15]. Two studies were laboratory studies using animal models (n=2) [27,28].…”

“…Wang et al [21] studied secondary infection rates among 124 families. Guedes et al [20] considered healthcare settings of Hemodialysis units and studied the association between different NPIs and the presence of COVID-19 clusters. Nabirova et al [15] considered oilfield workers who lived in camps, and compared different variables associated with workers from the same camp who tested positive and negative for SARS-CoV-2.…”

“…No association : Guedes et al [20] studied haemodialysis units through questionnaires and Telford et al [24] studied long-term care facilities through virtual and in-person site visits. In both cases, they found no difference in transmission among the settings that implemented enhanced disinfection measures and settings that did not.…”

The purpose of this review was to identify the effectiveness of environmental control (EC) non-pharmaceutical interventions (NPIs) in reducing transmission of SARS-CoV-2 through conducting a systematic review. EC NPIs considered in this review are room ventilation, air filtration/cleaning, room occupancy, surface disinfection, barrier devices, CO 2 monitoring and one-way-systems. Systematic searches of databases from Web of Science, Medline, EMBASE, preprint servers MedRxiv and BioRxiv were conducted in order to identify studies reported between 1 January 2020 and 1 December 2022. All articles reporting on the effectiveness of ventilation, air filtration/cleaning, room occupancy, surface disinfection, barrier devices, CO 2 monitoring and one-way systems in reducing transmission of SARS-CoV-2 were retrieved and screened. In total, 13 971 articles were identified for screening. The initial title and abstract screening identified 1328 articles for full text review. Overall, 19 references provided evidence for the effectiveness of NPIs: 12 reported on ventilation, 4 on air cleaning devices, 5 on surface disinfection, 6 on room occupancy and 1 on screens/barriers. No studies were found that considered the effectiveness of CO 2 monitoring or the implementation of one-way systems. Many of these studies were assessed to have critical risk of bias in at least one domain, largely due to confounding factors that could have affected the measured outcomes. As a result, there is low confidence in the findings. Evidence suggests that EC NPIs of ventilation, air cleaning devices and reduction in room-occupancy may have a role in reducing transmission in certain settings. However, the evidence was usually of low or very low quality and certainty, and hence the level of confidence ascribed to this conclusion is low. Based on the evidence found, it was not possible to draw any specific conclusions regarding the effectiveness of surface disinfection and the use of barrier devices. From these results, we further conclude that community agreed standards for well-designed epidemiological studies with low risk of bias are needed. Implementation of such standards would enable more confident assessment in the future of the effectiveness of EC NPIs in reducing transmission of SARS-CoV-2 and other pathogens in real-world settings. This article is part of the theme issue ‘The effectiveness of non-pharmaceutical interventions on the COVID-19 pandemic: the evidence’.

There is a lack of reference to infection control performance of Hemodialysis unit nurses. This study was to descript the priority of clinical needs in infection control for hemodialysis unit nurses. A web-based survey was conducted on 157 hemodialysis unit nurses after Delphi study. Data were collected using the developed infection control content tool. Borich Needs & the Locus for Focus model analysis was performed to screening the priority of clinical needs. The priority of clinical needs was selected six sub-domains in the infection control content. Most of the infection control content was difficult to perform compared to their perceived importance. It is expected that the priority of described clinical needs will be a milestone to improve infection control performance of hemodialysis unit nurses.
