Biological Indicators (BIs), which are considered to be the industry standard tool for determining hydrogen peroxide vapour decontamination efficacy. Full documentation was provided via a final report outlining all areas decontaminated including locations of biological indicators with incubation results displaying validated efficacy. Not only available as a service response, Bioquell systems are deployed around the world for everyday use in hospitals and care providers in the fight against the pandemic. A specialist unit at a Singapore hospital has selected multiple Bioquell units to help them in their response to control the spread of infections. As a current client of Bioquell, they expanded their capacity to decontaminate rooms, allowing them to support the running of a higher number of decontamination cycles following terminal clean as their current workload increased 300% on last year. Hospitals in the United States, Scandinavia, China, Qatar, New Zealand, and more, have all invested in Bioquell decontamination equipment to help eliminate organisms on every exposed surface in between patient admission. In fact, just prior to the pandemic, one of

Britain’s busiest hospitals, St Thomas’ hospital, which takes in patients from all over the world, worked with Bioquell on a nine-month trial assessing the impact of Bioquell’s hydrogen peroxide vapour decontamination system. As for any hospital, maintaining a low rate of hospital acquired infections is a top priority. That is why this facility required a room decontamination solution that could provide a 6-log sporicidal kill within hospital rooms performed as rapidly as possible in the short window that a hospital bed space is unoccupied. St Thomas’ needed the ability to decontaminate larger, open patient areas to help minimise the spread of infection between patients.

During the nine-month trial, Bioquell

performed over 460 room decontaminations, and, at one point, the system was used non- stop over a 72-hour period to help combat an outbreak on the ICU. By providing 6-log decontamination cycles in patient rooms and larger critical areas like operating theatres, the Bioquell system played a key role in minimising the spread of healthcare-acquired infections within the hospital. Ultimately, SARS-CoV-2 is estimated to

survive several days on skin and on surfaces, according to several scientific studies5,6


Frequent cleaning and disinfection of surfaces and proper hand hygiene have been identified as critical measures to help stop the spread of SARS-CoV-2, according to the World Health Organization.7

Effective hand

hygiene and surface disinfection are critical in preventing the spread of viral infection and are central pillars in protecting patients and staff as UK hospitals continue to face challenges in tackling the coronavirus. CSJ
