We have just had a study published in Clinical Infectious Diseases exploring the extent and magnitude of hospital surface and air contamination with SARS-CoV-2 during the (first!) peak of COVID-19 in London. The bottom line is that we identified pretty extensive surface and air contamination with SARS-CoV-2 RNA but did not culture viable virus. We concluded that this highlights the potential role of contaminated surfaces and air in the spread of SARS-CoV-2.
The next instalment of the HIS audience-led webinar series is on the role of contaminated surfaces in COVID-19 transmission. I was delighted to be part of the panel for this one:
- Dr Lena Ciric – Associate Professor in Environmental Engineering, University College London
- Dr Stephanie Dancer – Consultant Microbiologist, NHS Lanarkshire and Professor of Microbiology, Edinburgh Napier University, Scotland
- Dr Manjula Meda – Consultant Clinical Microbiologist and Infection Control Doctor, Frimley Park Hospital
- Dr Jon Otter – Infection prevention and control Epidemiologist, Imperial College London
- Chair: Dr Surabhi Taori, Consultant microbiologist and infection control doctor, Kings College Hospital NHS Foundation Trust
Here’s the recording:
I’ve spent the last couple of days up in Liverpool for Infection Prevention 2019. One of the highlights was a talk by Dr Paz Aranega-Bou on the issues around contamination of sinks and drains. Paz flagged a paper just published in JHI investigating the dispersal of CPE in a sink/drain test risk at PHE, showing the CPE can make its way from contaminated drains to sink and surrounding surfaces via splashback.
Brett Mitchell and colleagues have just published the exciting findings of the Researching Effective Approaches to Cleaning in Hospitals (REACH) study in the Lancet Infectious Diseases, along with my editorial. This large 11-centre randomised intervention study found that a low-cost enhancement to environmental hygiene managed to significantly reduce VRE infections, but did not reduce S. aureus bacteraemia or C. difficile infections.
A paper has just been published in ARIC as the first academic output of the Healthcare Cleaning Forum. I blogged earlier this year to relate the inaugural Healthcare Cleaning forum, and this paper expands on the key themes: establishing environmental hygiene as a patient safety initiative, providing an overview of the importance of environmental hygiene in healthcare, exploring the human factors driving the standards of environmental hygiene along with the need for effective education, the possibilities and challenges of automation, and the cost and value of environmental hygiene.
One of the key aims of the forum is to be a champion for environmental hygiene professionals. There’s a famous story of when president JFK visited NASA and asked a janitor who was mopping the floor what they were doing. The answer was simple and profound: “I’m helping to put a man on the moon.” If you asked somebody working in environmental hygiene in your hospital what they were doing, would the response be: “I’m helping to maximise patient safety and prevent healthcare-associated infection.” Probably not. We need to champion the cause of environmental hygiene professionals, who lack professional status, are often not paid enough, and often have limited options for career progression.
Is environmental a treasured investment priority in hospitals?
Related to this is our perception of the cost and value of environmental hygiene in hospitals. Is our level of investment appropriate given the risks associated with inadequate environmental hygiene in hospitals? Would we really find highly valued cleaning and disinfection materials in the metaphorical safe of a hospital manager (see the cartoon above)? Probably not! We need work towards better evidence to understand the value of environmental hygiene in hospitals in the context of other investment priorities.
A high profile article was published earlier this year in Science Translational Medicine, suggesting that Enterococcus faecium can exhibit clinically relevant levels of tolerance to alcohol-based hand hygiene products. The article has generated a huge amount of press coverage and discussion amongst experts. So, I thought it was about time I gave the article a once over. My initial thought was this would be unhelpful extrapolation of low-level tolerance to alcohol gel that wouldn’t be meaningful in a clinical setting. But having read the paper, there’s genuine concern here. Overall though, if true resistance to alcohol gel was going to be a problem, I’m pretty sure it would have reared its ugly head already.
In honour of Infection Prevention 2018, Brett Mitchell and I are having a blogoff so that you can choose the best IPC article of 2018. This post presents my case, Brett’s post (here) presents his case, and there’s a vote below so that you can choose. The results will be published next Monday morning at Infection Prevention 2018…
I was asked to write a series of articles in the Nursing Times (along with my colleague and co-author Tracey Galletly) on the role of nurses in environmental hygiene*. Et voila:
- Environmental decontamination 1: what is it and why is it important?
- Environmental decontamination 2: the role of the nurse
- Environmental decontamination 3: auditing cleaning and disinfection
I’ve been struggling for years to find the best ‘catch-all’ term to describe hospital cleaning or disinfection or both. And, after much thought, I’ve settled on a proposal to share with you, dear reader: “environmental hygiene”.
