Manchester-based transplant surgeon Dr Rajinder Pal Singh’s innovative use of an under-mask beard cover, traditionally referred to as the ‘thattha’ by Sikhs, to allow him to wear an FFP3 respirator mask – an essential personal protective equipment (PPE) for frontline medics – has passed the National Health Service (NHS) qualitative fit test.
He explains: “Respirator masks are the ideal respiratory protective equipment (RPE) for protection from small virus particles such as Covid-19, as well as from industrial toxic gases and smoke.
“In the current pandemic, for safety reasons, these masks are mandatory for healthcare workers exposed to aerosol generating procedures (AGPs) involving Covid-19. Wearing these masks requires a person to be clean-shaven to allow for a robust face-mask seal. There is no evidence to suggest why, instead of shaving, the facial hair factor cannot be overcome with an under-mask beard cover.”
The so-called “Singh Thattha”, which enables bearded medics to wear a well-fitting respirator mask while on frontline Covid-19 duties without the need for shaving, has also proved effective in initial trials.
A team, led by Professor Gurch Randhawa from University of Bedfordshire and Dr Singh (pictured), sought to work on a solution following numerous calls by Public Health England (PHE) to protect doctors from ethnic minorities, including Sikh, Jewish and Muslim communities who tend to have beards for religious reasons.
“Because shaving was a mandatory pre-requisite for wearing respirator masks, many members of the faith-observant bearded community, such as Sikh, Jewish and Muslim, have been affected and have had to face the dilemma of redeployment from frontline healthcare jobs involving exposure to Covid-19,” said Randhawa, Professor of Diversity in Public Health at the University of Bedfordshire and Director of the university’s Institute for Health Research.
“Redeployment to other areas incurs a loss of skillset and need for re-training, and junior doctors have had their training impacted,” he said.
According to the University of Bedfordshire, an initial trial meant that there appeared to be a choice – that shaving may not be essential to don a respirator mask. However, the technique needed reproducibility in order for the process to be established and declared safe.
That is where a partnership between Prof. Randhawa and Dr Singh led to an in-depth study of the promising and innovative alternative. The duo also teamed up with a group of co-authors for the study – Dr Sukhpal Singh Gill of the Sikh Doctors and Dentists Association (SDDA), Dr Sukhdev Singh of the Sikh Doctors Association, Dr B.S. Ubhi, Dr Gaggandeep Singh Alg, Dr H.S. Safri and Dr Gurpreet Singh.
Over the past few months, the team have collaborated to evaluate the efficacy of the “Singh Thattha” technique and the study findings, published in the ‘Journal of Health Infection’, showed that 25 out of 27 bearded Sikh dentists had been able to pass the qualitative “Fit Test” using the under-mask beard cover.
“Facial hair, albeit an accepted risk factor for face-mask leakage, can be overcome by using an under-mask beard cover,” the study concludes.
