Concern About New Recommendations to Relax COVID-19 Prevention Measures

An expert in microbiology has expressed concern about the new UK Health Security Agency (UKHSA) recommendations on COVID-19 infection prevention and control (IPC) around elective procedures.

The recommendations include three interventions which relate to social distancing and testing in NHS and Social Care elective care services, and a removal of enhanced cleaning practices.

The new recommendations advise that enhanced cleaning can be discontinued in low-risk areas. Providers have been told that they can now revert to standard cleaning procedures. The decision is based on advice by the Scientific Pandemic Insights Group on Behaviour (SPI-B) that hand hygiene is likely to be more effective than enhanced cleaning of surfaces.

But Dr Simon Clarke, Associate Professor in Cellular Microbiology, University of Reading, says the removal of enhanced cleaning “smacks of corner cutting.”

SPI-B advice

The SPI-B advice is based on “observations” that hand hygiene is likely to be more effective than surface cleaning in controlling the coronavirus, but that does not mean it is unimportant and can safely be cut, Dr Clarke has cautioned.

“Moreover,” he said, “SPI-B are a committee of behavioural scientists, not virologists or microbiologists and they are unlikely to be qualified to make such judgements. Indeed, SPI-B cite a NERVTAG paper which also called for further studies in this area, rather than leaning on any hard data. Enhanced cleaning is common in healthcare settings which are exposed to influenza patients so it seems that penny pinching by removal of enhanced hygiene measures may well lead to transmission of COVID-19 and other infections in our hospitals.”

He also warned that the elimination of polymerase chain reaction (PCR) testing before procedures will leave vulnerable patients at risk of infection.

UKHSA has recommended that selected patients in low-risk groups who are fully vaccinated and asymptomatic will now only require a negative lateral flow test on the day of their procedure and will no longer need to have a negative PCR and isolate for three days.

"The removal of the requirement for negative PCR testing before certain procedures for fully vaccinated, low risk patients reflects the level of protection that the vaccine provides against severe disease. However, false negative test results will mean that some asymptomatically infected patients will be put on wards with vulnerable patients,” Dr Clarke said.

Physical Distancing

The recommendations also include a reduction in physical distancing from 2 metres to 1 metre in areas where patient access can be controlled. This will not apply to emergency departments and other areas where access cannot be controlled. UKHSA says the guidance is based on advice from the World Health Organization (WHO) that physical distancing can be reduced to 1 metre in health care settings.

UKHSA hopes that the recommendations in starting to reduce enhance Covid specific IPC measures will also help to ease the pressure created by the pandemic on NHS capacity over the next few months, balancing the different health needs of the population as we learn to live with the virus.

Commenting on the new guidance, Dr Jenny Harries, UKHSA Chief Executive said: "We have reviewed the existing COVID-19 IPC evidence based guidance and made a series of initial pragmatic recommendations on how local providers can start to safely remove some of the interventions that have been in place in elective care specifically for COVID-19."

"This is a first step to help the NHS treat more patients more quickly, while ensuring their safety and balancing their different needs for care."

The NHS Confederation, which represents the whole health care system in England, Wales and Northern Ireland, has broadly welcomed the UKHSA recommendations but says the need for vigilance remains important.

Dr Layla McCay, director of policy at the NHS Confederation, said: "Healthcare leaders will welcome this review of the restrictions introduced during the early days of the pandemic. The recommended changes will help to increase efficiency and capacity within healthcare settings and give healthcare leaders and their teams the flexibility they need at a time when everyone is working so hard to increase the numbers of patients that can be safely diagnosed and treated."

She said the guidance will offer an opportunity to increase bed capacity on wards and will allow an increase in the patients being seen for a variety of procedures.

"However, we must remember that Covid-19 has not gone away. NHS organisations know this well and will not take their eye off the ball when it comes to infection prevention and control - not least as we approach what we anticipate will be a very difficult winter with the NHS affected by rising infections from Covid-19 to flu."

She cautioned that some health care organisations and systems may have to adapt their IPC measures again depending on local need.

Local Risk Assessments

UKHSA says implementation of the recommendations should be based on a risk assessment of local factors, such as the configuration of wards/departments, local capacity and the ability to ventilate spaces.

It also advises that staff working in areas where COVID-19 control measures have been relaxed should be fully vaccinated, be asymptomatic and not be a contact of a positive case. Staff will be required to continue to comply with the current guidance on asymptomatic testing. Rigorous adherence to routine IPC precautions by all staff remains critical for patient safety and must continue to be implemented.

The recommendations only apply to elective care. UKHSA describes them as the first step and says further changes are planned in relation to other services and environments.
