Reducing Waterborne Infections in Healthcare Environments

Waterborne infections are something most site managers will be aware of, with checks routinely carried out to mitigate the risk of Legionella and Pseudomonas aeruginosa. However, a growing body of evidence indicates that the risk of hospital-acquired infections (HAIs) and non-tuberculosis mycobacteria (NTMs) is increasing, making them increasingly dangerous waterborne pathogens. 

NTMs are particularly dangerous for patients and visitors to healthcare facilities, especially if they are immunocompromised, infants, elderly, or anyone undergoing heart surgery, transplants or living with cystic fibrosis. For these people, NTMs can cause pulmonary, central nervous system, and soft-tissue infections.

So what does this new threat of NTMs mean?

Site managers in clinical and healthcare settings are becoming increasingly vigilant in ensuring that new refurbishments and new-build facilities include features to mitigate these risks. As well as routine checks and servicing already carried out for things like Legionella, there is a move toward fixtures that support infection prevention and control, too. 

Our biggest issue in the healthcare environment is dead water, bacteria-friendly water temperatures, and the formation of biofilm, which enables NTMs to develop and spread. A particular site of concern is the shower, as NTMs pose a high risk of inhalation exposure, which can occur during and after showering.

A unit to reduce the risk of NTMs

The Markwik 21+ Shower Panel with Thermostatic Mixer Valve is a strong move in infection prevention and control (IPC). The range has been designed to specifically reduce microbial growth by incorporating more antimicrobial brass into its construction. The item is also made using narrow-bore water pipes. This increases the velocity of the water passing through it, reducing its opportunity to stick to the sides and form a biofilm, where waterborne bacteria can build. 

The thermostat is also located very close to the outlet on these shower panels, which means you get more accurate water temperature and a lower likelihood of bacteria-friendly temperatures in the pipework.
