Effectiveness of UV-C Technology for Environmental Decontamination of Clostridioides difficile in Hospital Settings: A Pre-Post Analysis

1

Clostridioides difficile infection (CDI) is the most common healthcare-associated infection in the U.S., necessitating effective prevention strategies.
2

Standard disinfection for C. difficile involves a bleach solution, but alternative non-touch methods like UV-C technology are being explored.
3

This study evaluated the effectiveness of UV-C devices in reducing C. difficile contamination in hospital rooms occupied by CDI patients.
4

Environmental samples were collected from high-touch surfaces before and after UV treatment to assess contamination levels.
5

The study aims to provide evidence on the real-world effectiveness of UV devices for C. difficile decontamination in hospital settings.
