Disinfection and germicidal treatment systems using UV lamps are in use across the healthcare sector


Healthcare operations are using ultraviolet light as part of their disinfection processes as a more environmentally friendly approach for air and wastewater treatment. These can be standalone treatment systems or depending on requirements, be combined with traditional cleaning methods to create an enhanced cleaning regime.

Helping to disinfect patient rooms, equipment and improve air quality in hospitals, surgeries, dentists and other healthcare settings.

An example of how this works can be found in hospitals when cleaning patient rooms. Manual cleaning of rooms is still carried out by hospital staff, but time constraints may mean that thorough cleaning of all surfaces (with enough contact time of disinfectant chemicals) is not possible. In addition, some HAIs (hospital-acquired infections) such as MRSA and C. Difficile have been seen to develop resistance to cleaning chemicals, or are carried in spores that can be missed by liquid disinfectants.

Using ultraviolet light based disinfection treatments to enhance manual cleaning methods provides an added layer of defence. Researchers at the Duke University School of Medicine in the US found that using portable UV disinfection systems in addition to standard cleaning strategies significantly decreased transmission of selected bacteria in patients who stayed overnight in a room where an infected patient was previously treated.

In January/February 2021 tests on virus levels were also conducted in two repurposed COVID-19 units in Addenbrooke’s Hospital, Cambridge, UK. Airborne SARS-CoV-2 was detected in the ward on all five days before activation of a HEPA/UV combination system but on none of the five days when the HEPA/UV filter was operational. 

The report stated that portable air filtration systems, that combine high-efficiency particulate filtration and ultraviolet (UV) light sterilisation, may be a scalable solution for removing respirable SARS-CoV-2.

UV technology is also used to help disinfect cabinets used for cleaning surgical tools and other equipment.
