Covid-19: Doctors’ leaders call for revised PPE guidance to reflect new variantsBMJ 2021; 372 doi: https://doi.org/10.1136/bmj.n146 (Published 15 January 2021) Cite this as: BMJ 2021;372:n146
Medical leaders have urged Public Health England to strengthen its guidance on personal protective equipment (PPE) to reflect the more transmissible forms of SARS-CoV-2 that healthcare staff are being exposed to.
Current guidance says that higher grade FFP3 masks should be provided to staff who are involved in aerosol generating procedures, but other staff looking after patients with covid-19 are only required to wear fluid resistant surgical masks.
In a letter to Public Health England sent on 13 January, BMA council chair Chaand Nagpaul said that, in light of the identification of the new variant of SARS-CoV-2, increased spread of the virus, and growing evidence of aerosol transmission, Public Health England should review its recommendations on PPE usage “so that a more precautionary approach is adopted to the provision of respiratory protective equipment (RPE) to ensure staff are protected from aerosol transmission.”
He wrote: “There are significant and growing concerns about the role of aerosol transmission of covid-19 in healthcare settings, and the need for wider use of RPE (for example, FFP3 respirators) outside of those procedures designated as aerosol generating. We are therefore calling on [Public Health England] to support the wider use of RPE in other high risk settings across primary and secondary care.”
Nagpaul mentioned evidence indicating lower infection rates among staff in areas where higher grade RPE is currently recommended.1 He also pointed out that the World Health Organization modified its guidance in December to advise that where respirators were available, they should be considered for wider use.2
The Doctors’ Association UK also called on Public Health England to review its guidelines on PPE for healthcare workers. The organisation said that there were 44 000 NHS staff currently absent because of covid-19, with many becoming unwell because of the new, more transmissible variant.
Katie Sanderson, spokesperson for the association, said, “Healthcare workers in the UK continue to become infected with covid-19 at work at rates that could be mitigated by access to better personal protective equipment.”
Jenny Vaughan, vice chair of the Doctors’ Association UK, said that the organisation was “calling for a full review of the PPE guidelines including wider access to FFP3 masks. So many NHS staff are getting sick because of the new, more transmissible variant. The covid-19 virus has changed, and yet the same guidelines we introduced in March have not been updated.”
Ensuring greater protection was especially vital for staff who were more at risk from covid-19, such as doctors from an ethnic minority background, the medical bodies said.
The interventions follow a similar call from Fresh Air NHS, a group of frontline healthcare workers who recently wrote an open letter to UK politicians urging them to recognise the importance of airborne transmission of SARS CoV-2 and to ensure that measures were in place to protect staff and patients.3
Yvonne Doyle, medical director at Public Health England, “NHS staff are under immense pressures and their safety has always been our highest priority. The NHS Infection Prevention Control group has reviewed the latest evidence and has advised that PPE should continue to be worn as laid out in the current [infection prevention and control] guidance, with FFP3 masks required for staff undertaking clinical aerosol generating procedures. This is supported by [the World Health Organization]. Emerging evidence and data on variant strains and transmission will be continually monitored and reviewed.”
