Researching Approaches to Cleaning in Hospitals (REACH)


aushsi reachWhy the research project is important

Healthcare associated infections (HAI) are a major cause of avoidable costs, morbidity and deaths among hospital patients. Reducing important HAI requires multiple evidence-based approaches, including a focus on environmental cleaning. It is important to understand the impact of cleaning interventions on HAI rates and their cost-effectiveness.

What the research seeks to do

The REACH study aimed to evaluate whether a new, bundle approach to hospital cleaning was an effective and cost-effective way to reduce the transmission of healthcare associated infections (HAIs) in hospitals.

What are the research outcomes/ impact

The REACH trial implemented an evidence-based cleaning bundle in 11 Australian hospitals. The intervention was associated with improved cleaning of frequent touch points and lower rates of Staphylococcus aureus bacteria (SAB) and vancomycin-resistant enterococci (VRE) infection. Adopting the bundle had an 86% chance of being cost-effective, compared with existing hospital practices.

This study generated evidence for the cost-effectiveness of the REACH cleaning bundle as an infection prevention strategy in hospitals.
