There’s a huge amount of academic and pragmatic discussion and debate about the appropriate levels of PPE to wear in various healthcare settings to reduce the risk of spreading COVID-19 to yourself and others in healthcare settings. And more recently, when to wear face coverings / masks / shields in public areas of hospitals, on public transport, and in shops. However, there is much, much less discussion about the importance of careful doffing (removal) of PPE and face coverings etc in order to ensure the safe and effective use of PPE. This helpful Cochrane Review, updated for the COVID-19 era, covers a lot of ground and one key conclusion is that doffing is key: if it is done carefully, the risk of self-contamination is lower.
The case for face shields in preventing the spread of COVID-19
I’ve been meaning to write this post for a while. As UK government guidance has changed, face masks and face coverings will be very much the norm on public transport and in healthcare settings soon. So, now is a good time to consider whether face shields could play a role in preventing the spread of COVID-19.
