Improving hospital cleaning and disinfection
This post shares the findings of a recent study exploring improving hospital cleaning and disinfection through streamlining product and enhanced training. A team working in Lanarkshire, the third largest health board in Scotland, has recently published a study evaluating the impact of an intervention to improve hospital cleaning and disinfection through the implementation of pre-impregnated wipes combined…
Read MoreSporicidal disinfection should be the basis of all bundles to prevent C. difficile infection
Since the evidence base is limited, knowledge on what really works to prevent the transmission of pathogens that cause HCAI is limited. This is the case for C. difficile and other hospital pathogens. So, we commonly apply bundles of interventions, in the hope that one or more elements of the bundle will be effective. A recent modelling study helps…
Read MoreNeutralising duff “sporicidal” claims of amine-based disinfectants
There is a lot of value to a disinfectant manufacturer of having a sporicidal claim so that the product can be used in healthcare settings to tackle C. difficile spores. However, not all products with a sporicidal claim are in fact sporicidal! Amine-based disinfectants with “sporicidal” claims are being seen increasingly in the marketplace, but these products are unlikely…
Read MoreTime to disinfect the loo before flushing?
A fascinating new study in AJIC suggests that adding a disinfectant to the toilet bowl before flushing results in a significant reduction in viral contamination of a bathroom. Does this mean we should disinfect the loo before flushing it? The study used MS2 coliphage as a proxy marker of pathogenic virus contamination. The degree of…
Read MoreIs your wipe really sporicidal?
Sporicidal disinfectant wipes are being used increasingly for tackling surfaces contaminated with C. difficile spores in hospitals. A wide range of ‘sporicidal’ wipes are coming onto the market. However, concerning published data shows that some wipes marketed as being ‘sporicidal’ do not have meaningful activity against spores when tested under controlled laboratory conditions. This blog outlines three key questions…

Another IPS conference has been and gone, and what a lot of fun and learning to be had! New research published, new products launched, and new contacts made – all in a few days in sunny Harrogate. Several of the lectures were outstanding: Prof Gary French on the ‘swing’ away from antibiotic-resistant Gram-positive bacteria towards…
Read MoreTransmission of C. difficile: Asymptomatic carriers are also a risk
A new paper from Canada that has examined the effect of screening and isolation for asymptomatic carriers of toxigenic C. difficile has just been released onto the JAMA Internal Medicine website. In this study, 4.8% of patients screened were found to be carrying the tbD gene and these patients were part of an intervention group that included isolation, but not in…
Read MoreStandardising the testing of disinfectant wipes
There has been quite a bit of discussion lately about the suitability of laboratory testing methods for wipes. This is a crucial issue, and may explain to a large degree the differences in wipe performed when tested in parallel. For example, a study of wipes with sporicidal claims found that few actually demonstrated meaningful sporicidal activity! A recent…
Read MoreSporicidal Study
A newly published paper (Doan, 2012 – Clinical and cost effectiveness of 8 disinfection methods) has shown that Clinell Sporicidal Wipes are proven to be more effective at reducing spore counts than chlorine releasing agents. Doan acknowledges the deficiencies of Chlorine and in particular the likelihood of non compliance. Sporicidal wipes were easy to use and the fastest…
