Investigating Drain-Life

Multiple studies have identified that handwash basin, sink and shower drains and ubends play a role in the transmission of healthcare-acquired antibiotic-resistant infections, particularly those caused by Klebsiella spp., Pseudomonas aeruginosa and Escherichia coli.  The niche environment of healthcare drains and ubends supports biofilm formation and populations, enabling ease of microbial genetic exchange.  Where multi-drug […]

Water Sources Highlight A Patient Care Gap

Clinical handwash basins, healthcare sinks and showers along with their u-bends and wastewater drains are not addressed as infection sources.  The plethora of recently published waterborne infection data has not been translated into meaningful improvements in patient or environmental surveillance, remediation within Water Safety Groups, nor have training materials to essential supporting services, including Plumbers

Recognising Hazards & Seeing Risks

Sinkevitch and co-workers from the US Centers for Disease Control & Prevention (CDC) have recently reported on the investigation into three cases of Mycobacterium abscessus colonisation and/or infection in ventilator dependent paediatrics at a residential facility.  Mycobacterium abscessus is one of the Non-Tuberculous Mycobacterium (NTM) species responsible for severe respiratory, skin and mucosal infections, and

Think Pink – Serratia marcescens strikes again

Occasionally a paper pops up which raises a red flag of concern – or in this case pink.  Serratia marcescens belongs to the Enterobacteriacae family and is a common water dweller.  There have been reports of hospital-acquired infection and outbreak, including multi-drug-resistant epidemic events, in immunocompromised, critically ill patients, those undergoing haemodialysis and those in

Continuous Risk Recognition from Drinking Water Sources

Recent publications have supported recognition of risk relevant to in-premise water services, and this month our attention has been captured by three American publications. Firstly, Najjar-Debbiny et al. report a high prevalence (>40% of environmental samples positive) of Carbapenemase-Producing Enterobacteriaceae within 1 meter of any water source.  This data is highly relevant for Water Safety

Derogate to Improve In-Premise Water Hygiene

The new NHS England publication on “Processes for Managing & Reporting Derogations from Estates Technical Standards & Guidance” (https://www.england.nhs.uk/long-read/processes-for-managing-and-reporting-derogations-from-estates-technical-standards-and-guidance/) is welcomed. The publication acknowledges the importance for healthcare facilities to be designed and constructed to the highest and most appropriate level in order to deliver clean, safe and secure environments.  In addition it sets out

The conflicts between energy-saving and water hygiene

Ongoing drivers in environmental sustainability have led to pressure and increasing responsibility on building owners and managers to consider energy saving measures during day-to-day operation of their premises that can contribute toward both carbon zero targets, waste reduction, and demonstrable cost savings.  One area under close scrutiny is the efficient and effective management of hot

Multi-Drug Resistant Microorganisms In Your Drains

Evidence linking the role of water services – both potable influent and waste waters – in the transmission of waterborne pathogens such as Legionella pneumophila, Pseudomonas aeruginosa, Non-tuberculous Mycobacteria and their resulting infections has increased significantly in recent years.  The reported in-premise multi-drug resistant waterborne infections such as from Pseudomonas aeruginosa, P. putida, Klebsiella pneumoniae,

Is Bottled Drinking Water Quality Suitable for Patient Consumption?

The provision of bottled water for patient consumption and assessment of the microbial risk remains a blind spot for infection prevention teams and water safety groups.  Few consider that bottled water could be a source of Pseudomonas aeruginosa or other waterborne pathogens. There are times when bottled water could be safer and a logistically favourable
