The CLEEN study: Background and discussion with the authors

Our guest host, Dr Sally Havers this week talks to some of authors from ClEaning and Enhancd DisinfectioN (CLEEN) study (including some regular voices..). The study was recently published in the Lancet Infectious Disease (link below).

The CLEEN study is a world first RCT that explores the impact of cleaning and disinfection of shared medical equipment on HAIs. The study reports significant reductions in HAIs associated with increased cleaning and disinfection of shared equipment.

In this chat, the background to the study is discussed, as well as some implementation and practical considerations. We also touch on the time it takes to clean, which is related to another paper from the CLEEN study recently published in the Journal of Hospital Infection.

For those attending the 2024 IPS conference in Birmingham in a few weeks, Brett will be presenting the full methodology and main effectiveness results at the conference. Early cost-effectiveness data will also be presented, as well as results from a time and motion study exploring how long it takes to clean equipment.

For those attending the 2024 ACIPC conference in Melbourne in November, there is a concurrent session on the main effectiveness results and a lightning session on how long it takes to clean equipment.
