Infection control: protecting staff and patients
Optometrist and AOP clinical director, Dr Peter Hampson, discusses infection control in practice during the pandemic
11 April 2021
Looking at the basics of infection control, there are a number of areas that are important to creating a safe working environment for you, practice staff and patients. These include personal protective equipment (PPE), ventilation and vaccines.
Everybody should be wearing PPE. This advice has not really changed since the beginning of the pandemic – if you are working with patients within a distance of two metres or less, then you should be wearing the appropriate PPE.
AOP resourcesThe AOP has produced a range of policies and posters to support practitioners. These are available to download from its website: www.aop.org.uk/coronavirusupdates
It is worth keeping in mind that wearing gloves doesn’t remove the need for good hand hygiene from all members of staff. In the absence of gloves, good hand hygiene is able to mitigate the risk. If you haven't got any open sores or broken skin, and hand hygiene is maintained, risk can be mitigated as there is no known risk of contracting COVID-19 through intact skin.
Wearing face masks is of upmost importance for all practice staff and patients for two reasons, not only can you stop someone breathing out the virus, you can reduce how many virus particles you are breathing in. There will be some patients who cannot wear a face mask, so reducing these interactions and wearing a mask yourself is key.
Consulting rooms don’t normally have any natural ventilation and in those instances, filtration units with approved HEPA filters can be used to reduce risk
VentilationI know lots of practices that have added screens in areas and that’s great, but there is some debate about how effective they are in terms of the size of the particles in the air. So, while the screens help when dealing with two metre droplets, they aren’t necessarily great if particles are floating in the air. This is where ventilation becomes key as good air flow can dilute the virus.
Ventilation is really important due to the aerosolisation risk associated to the virus. Aerosolised particles have been linked to an increased risk of disease spread as viruses linger in the air.

These devices are not overly expensive and may present a sensible way of reducing the viral load in the consulting room.
Vaccines are really important as they can protect against infection or disease, so it is important that we myth-debunk about this.
While the types of vaccines that are used vary and may work in slightly different ways, they all still stimulate an immune response, which cannot affect DNA, as we have sometimes heard.
Although the vaccine is being rolled out, it’s important not to get complacent. At least in the short term we still need to be wearing PPE, and good hygiene and cleaning has always been important, but even more so until we get the all clear. Looking beyond the pandemic, there are a number of processes that I think practitioners will continue with. I certainly think in the future face masks will at least become commonplace on a seasonal basis.
Three steps to success
- Don’t get complacent
- Increase ventilation however you possibly can
- Have the vaccine when offered.
