Pseudomonas Infection Control in Hospitals


In 2012 we heard of the tragic death of three babies from Pseudomonas aeruginosainfection in Belfast's Royal Jubilee Hospital. 

Pseudomonas aeruginosais a bacterium found in soil and stagnant water. It is not a problem for healthy people but it can cause serious infection among people with cystic fibrosis and those with weakened immunity (hospital patients, especially those with HIV/AIDS, cancer and the elderly). Premature babies and people with severe burns are also at risk.

There have been a number of other outbreaks of Pseudomonasinfection in UK hospitals, as well as the one in Belfast. Often infection is traced back to contaminated water in drains and sinks. Infected catheters and feeding tubes, and contaminated hands are a common source. The bacterium is tough and can survive for some time on a contaminated surface. The Health Protection Agency reports around 4,000 cases a year, mostly among babies and the elderly.

Whether Pseudomonas aeruginosacan be transmitted through the air, and whether this is a significant pathway of transmission (compared to established routes) is not clear. It is worth noting a research paper that showed that Pseudomonaswas present in tiny droplets (around three microns) in cough aerosols analysed from a group of patients with cystic fibrosis. 

Pseudomonasis, a relatively common source of healthcare (including hospital) associated infection and could be relevant for hospital air filtration in general. Looking at different options for pseudomonas infection control is important, because, as with many other infections, it is becoming resistant to antibiotics and therefore hard to treat. Pseudomonascan infect any part of the body with blood infection being particularly serious.

UVC air cleaners are often advertised as being able to “sterilises the air” and that the “air is disinfected” through the use of the UVC light in an air cleaner. But is that true? This article discusses the pros and cons of UVC air cleaners as an infection control measure.

Exploring airspace development for the NHS

December 16, 2021 1 min read

Airspace development refers to building new structures in the ‘air-rights’ on the roof of an existing building. Whilst this is not a new idea, airspace development is becoming an increasingly popular opportunity for developers to create new spaces in dense cities such as London, and changing policies and perceptions in government and local authorities means there is now more scope to explore the option.
