Updated PPE guidance puts NHS staff at risk of infection, say medics

NHS staff face unacceptable health risks as a result of “retrograde” changes to the government’s guidance on preventing spread of Covid-19, doctors’ leaders have warned.

The BMA said on 16 March it was concerned over updated guidance issued by the UK Health Security Agency covering use of personal protective equipment. It said the guidance failed to properly acknowledge that SARS-CoV-2 infection can spread in the air during the routine care of patients as they cough or sneeze and not just when specific processes known as aerosol generating procedures (AGPs) are being undertaken.

“This is a retrograde step as it once again means that healthcare workers will not be routinely provided the right level of protective masks and equipment they need to be safe at work when looking after covid patients,” said Chaand Nagpaul, the BMA’s chair of council.

The BMA said it was crucial that any staff looking after patients with confirmed or suspected Covid-19, or in other situations where a local risk assessment required it, had access to respiratory protective equipment such as filtering face piece (FFP3) masks.

Nagpaul said, “All healthcare workers who are caring for Covid-19 patients are putting themselves at risk, each and every day, and the very least the government should do is to provide surety that staff will be given the best protection possible.”

Respirators such as FFP3 masks are designed to protect the wearer from ingress of contaminated air and are fitted to ensure no gaps. They offer higher protection than surgical masks, which block the outward escape of droplets from the wearer.

The BMA’s concern follows a supposed clarification of the main messages regarding airborne transmission in the latest infection and prevention and control guidance issued on 15 March 2022.

The guidance said that respiratory protective equipment (FFP3 masks) are recommended when caring for patients with a suspected or confirmed infection spread “predominantly” by the airborne route (during the infectious period).

The word “predominantly” has been added to the previous guidance update, which was issued on 17 January 2022, and is the crux of doctors’ concern, one leading scientist said.
