During the first wave of the pandemic, p<\/span>atient facing healthcare workers and their families were statistically more likely to be admitted to hospital with covid-19 than non-patient facing staff or the general public. [<\/span>1] <\/span>Between March and May 2020, the NHS lost the equivalent of more than 1.3 million staff days owing to covid-19 and related reasons. [<\/span>2] <\/span>In a letter to all NHS trusts, general practices, and primary care networks<\/span>, dated June 2020, the chief operating officer, chief nursing officer, and national medical director for NHS England set out important steps to minimise these infections. [3] Yet in October 2020, 17% of covid-19 infections still fit the NHS England definition of probable hospital acquired infection. [<\/span>4]<\/span><\/p>\n

We know that wearing masks, using personal protective equipment (PPE), social distancing, adequate ventilation, and reduced person-to-person contacts will bring down the number of infections. [<\/span>5,6,7] <\/span>Micro-organisms from within the patient wards, transfer to clothes, curtains, computers, stethoscopes, clinical records, mobile telephones, and other devices have been implicated in healthcare associated infections. [<\/span>8,9,10] <\/span>Although covid-19 transmission is dominated by airborne routes<\/span>, the 653,000 cases of healthcare associated infections in adult patients per year in NHS general and teaching hospitals, even before the current pandemic, are alarming. [11,<\/span>12]<\/span><\/p>\n

Numbers of h<\/span>ospital beds in the UK have fallen, <\/span>and much NHS land<\/span> has been earmarked for development<\/span>, but patient numbers have increased. [13,14]<\/span> This means that more work is packed into smaller spaces that were not built to enable multiple zoning areas in hospitals. Relatives are becoming more important for delivering care at the bedside, not just because staffing levels are depleted, but also because families wish to care for their loved ones themselves. Visiting hours have become more flexible. The consequences include potential crowding of patients, relatives, and staff; loss of unobstructed walkways to wash basins or other disinfection areas in the clinical part of the ward; and loss of safe spaces for staff to eat, rest, shower, change clothes, or use the toilets. Clinical and non-clinical staff mix in offices. Computers can be shared, may not have screens around them, and be positioned less than 2 metres apart. [<\/span>15,16]\u00a0 <\/span>Domestic staff work tirelessly, but hours may be cut because of outsourcing. Staff spending hours in a workspace cannot go without food and drink, which means they will need to remove their facemasks. Older areas may not have adequate ventilation systems. Not everyone is aware <\/span>of the guidance of the Federation of European Heating, Ventilation and Air Conditioning Associations for how we improve clean air circulation. [17]<\/span><\/p>\n

The increased use of \u201cscrubs\u201d at work is welcomed<\/span>, but the absence of changing spaces in some areas can lead to additional overcrowding; as staff queue to change in small spaces or ward toilets. [18,<\/span>19]<\/span>\u00a0<\/span>In some countries, laundering is outsourced and staff need to take work clothes home to wash. But not all staff are aware of, or follow, safe laundering advice, and even so, micro-organisms are more likely to survive domestic rather than commercial or industrial laundering. [<\/span>20,21] <\/span>Evidence of methicillin sesistant\u00a0<\/span>Staphylococcus\u00a0<\/span><\/i>aureus transmission via healthcare uniforms already exists. [<\/span>9]<\/span><\/p>\n

Remote working may be the only viable solution to many of these problems and, despite multiple challenges, was taken up efficiently in the first pandemic. This reduces healthcare associated infections and improves air quality, with a positive impact on transmission and symptoms of many diseases. [<\/span>22,23] <\/span>Changing travel patterns lessens the risk of new viruses transferring from animals to humans. [<\/span>22,24]<\/span><\/p>\n

A striking feature of this epidemic has been the growth in information sharing across borders, without reference to political affiliations and often provided free at source, using modern information technology. [<\/span>24,25,26] <\/span>Seven thousand professionals from at least three continents attended WenHong Zhang\u2019s webinar on the Shanghai experience of covid-19. [<\/span>27] W<\/span>orking together rather than in competition has been inspirational and has helped tackle various problems. For example, PPE is more available, as is education on donning and doffing, but more needs to be done to raise awareness of the risk of infection through multiple interactions within a patient zone. [<\/span>21,28]<\/span><\/p>\n

The medical clinical lead for infection control can help to identify issues, provide local solutions, and link with Public Health England and similar bodies. Testing asymptomatic staff will help control infection rates. [<\/span>29] <\/span>Liaison with social care and educational services should be part of the new spirit of information sharing, nationally and internationally, to support cohesive strategies. Concepts of infectious diseases and infection control and the links with public health sciences must be embedded within the medical curriculum or taught even earlier, in school programmes.\u00a0<\/span><\/p>\n

So yes,<\/span>\u00a0we do need to talk about healthcare associated covid infection as the risks of not doing so are enormous. Beyond covid-19, the risks of other infections continue to be substantial. We need to tackle this now; for our own health, our patients\u2019 health, our colleagues\u2019 health, and our communities\u2019 health.<\/span><\/p>\n
