In our recent blog posts we have reviewed a number of important topics. In this post I want to summarize some of the key points from our previous posts and combine these findings with a handy infographic to summarize visually some of the key points.

To summarize some of our earlier posts;

  • In our review of bacterial and fungal contamination (available here and here) we found that infected or colonized patients typically shed a range of pathogenic bacteria including Clostridium difficile and Methicillin Resistant Staphylococcus aureus into their environment. In addition concern is rising around emerging fungal pathogens such as Candida auris prompting the CDC to suggest additional environmental cleaning is required as Candida auris can persist in the environment.
  • In our review of what surfaces are contaminated (here) we found a wide range of surfaces are contaminated but surfaces that are frequently touched and/or in close proximity to the patient are often the most colonized with nosocomial pathogens. Based upon the work of Dancer et al  we find that this is especially true for MRSA where bed linens, patients’ gown, and the overbed table were the commonest sites for MRSA contamination (approximately a mean of 40% of the sites).
  • In our latest post we reviewed the most touched surfaces by looking at two major studies, the first is  based upon the work of Huslage et al who demonstrated the bed rail, the bed surface, and the supply cart accounted for 40.2% of the contacts recorded in the ICU and on medical-surgical floors again the bed rail, the over-bed table, the intravenous pump, and the bed surface accounted for 48.6% of contacts. The second is the validation of these surfaces by Cheng et al who confirmed that the Huslage study high touch points including bedside rails, bedside tables, patients’ bodies, patients’ files, linen, bed curtains, bed frames, and lockers were mutually touched by HCWs, patients, and visitors.
