Plain English Summary

Background and study aims
The COVID-19 pandemic has wreaked havoc upon the education of a whole generation of school children. It is estimated that school children have lost at least a half of an academic year due to the pandemic. Education analysts have assessed the numbers of children achieving or exceeding the expected level for their age in reading, writing and maths compared with pre-pandemic scores.
Whilst rates of transmission of COVID-19 have dropped during the summer months there is a high risk that if no action is taken to mitigate airborne transmission, the risk of infection is likely to increase again in the autumn and winter seasons. The result being further school closures.
The aim of this study is to conduct an early phase trial of two air cleaning technologies with a focus on feasibility and practical implementation. The air cleaning technologies have the potential to mitigate the aerosol transmission of viral particles - including the SARS-CoV-2 virus - within schools. This study seeks to explore the practicalities and possible benefits of fitting schools with these technologies.

Who can participate?
The study will be conducted within 30 primary schools in Bradford, UK.

What does the study involve?
The study will have three arms: a control arm and two intervention arms; one with installation of portable high efficiency particulate air (HEPA) filter units, and the other with installation of germicidal ultraviolet (GUV) devices.

What are the possible benefits and risks of participating?
There is a potential benefit for children and staff within the schools with air cleaning technology (i.e. reduced infection from air bourne illness) but this remains to be determined. There are little to no risks associated with the research (the worse case scenario is a data breach that would reveal data – schools absences – that are already collected within the Local Authority).

Where is the study run from?
The study is run from the Centre for Applied Education Research which is based at the Bradford Teaching Hospitals NHS Foundation Trust, UK.

When is the study starting and how long is it expected to run for?
January 2021 to September 2022

Who is funding the study?
The study is funded by the Department for Health and Social Care (UK)

Who is the main contact?
Prof. Mark Mon-Williams, M.Mon-Williams@leeds.ac.uk

Intervention typeDevice
Pharmaceutical study type(s)
PhaseNot Applicable
Drug / device / biological / vaccine name(s)portable high-efficiency particulate air (HEPA) filter units, germicidal ultraviolet (GUV) devices
Primary outcome measureSchool absences for COVID-19 measured using anonymised data contained in schools information management systems and relayed to Local Authority at weekly intervals
Secondary outcome measures1. CO2, humidity, PM2.5 & PM10 levels in classrooms measured through air monitoring devices at 60 second intervals and relayed via API.
2. Power usage levels for HEPA devices measured through power consumption monitoring devices at 60 second intervals and relayed via API.
3. Primary and secondary Care level data will be collect via Connected Yorkshire data set at weekly intervals. The Connected Yorkshire programme links disparate routine electronic data in an anonymised database across primary care, secondary care, community care and social care for over 700,000 individuals at Bradford Teaching Hospitals NHS Foundation Trust.
