Does routine use of sporicidal disinfectants for all postdischarge hospital rooms reduce environmental contamination with Clostridioides difficile spores?

In a culture survey of 30 hospitals, rates of Clostridioides difficile spore contamination after cleaning and disinfection of non-C difficile infection rooms were lower in facilities using sporicidal disinfectants in all postdischarge rooms versus only in C difficile infection rooms (3.6% vs 5.1%, respectively), but the difference was not statistically significant.

A far ultraviolet-C light technology is effective for decontamination of items in proximity to sinks and is enhanced by a far UV-C reflective surface.

Background: Dispersal of gram-negative bacilli from sink drains has been implicated as a source of transmission in multiple outbreaks.

Methods: In an acute care hospital, we assessed how often patient care supplies and other frequently touched items were within 1 meter of sink drains. We tested the efficacy of a ceiling-mounted far ultraviolet-C (UV-C) light technology for decontamination of sink bowls and surfaces near sinks with and without a wall-mounted film that reflects far UV-C light.

Identifying and Remediating Super-splasher Sinks to Reduce Dispersal of Pathogens From Sink Drains.

Testing for dispersal of fluorescent gel from sink drains was sensitive for detection of sinks that dispersed gram-negative bacilli outside the bowl. Reducing the flow rate of sinks with rapid water inflow and/or elimination of obstruction leading to slow outflow was effective in preventing dispersal of fluorescence and gram-negative bacilli.
