Wastewater Interventions to Prevent Transmission of Deadly Bacteria

The role of the wastewater environment in nosocomial transmission of deadly bacteria such as multispecies carbapenemase-producing Enterobacteriaceae is increasingly recognized.A group of researchers led by Drs. Amy J Mathers and Costi D. Sifri from the University of Virginia recently demonstrated that environmental interventions that targeted wastewater-related transmission led to decreased acquisition and number of infections by carbapenemase–producing organisms.Covers were installed on all hoppers (a “toilet-like” waste disposal system) in adult intensive care units (ICUs) of a university hospital; additionally in the surgical ICU, sink trap heating and vibration devices were also installed. The intervention demonstrated a decrease in patient acquisitions of carbapenemase-producing Enterobacteriaceae.The questions I see are primarily financial. What is the cost effectiveness of the intervention? What is the return on investment? This is the data ID doctors would need to make the financial case to the hospital administration, to implement the intervention more broadly.

What do you think?

I’ll be offline for an amount of time that is yet undetermined…  If you need to contact me, feel free to email me (lederer at gmail dot com), contact me on Twitter or Instagram (@philiplederer). If you can’t reach me those ways, please reach out to my assistant, Mike McLoughlin. His email is mikedmc@hotmail.com.

And for something completely different… A song..
