Hospital Cleaning

The hospital environment is a reservoir for the transmission of microorganisms. The effect of improved cleaning on patient-centred outcomes remains unclear. The researchers aimed to evaluate the effectiveness of an environmental cleaning bundle to reduce health care-associated infections in hospitals. A major trial of a bundle of hospital cleaning practices in 11 Australian hospitals has made significant reductions; so healthcare-associated infections and demonstrated cost-benefits.
The study, “An environmental cleaning bundle and health care-associated infection in hospitals (REACH): a multi-center randomized trial”, was led by QUT health economist Professor Nick Graves from the Australian Centre for Health Services Innovation (AusHSI) at the Institute of Health and Biomedical Innovation (IHBI) and is published in The Lancet Infectious Diseases. It was funding by Australia’s National Health and Medical Research Council.
“This research project is believed to be the largest prospective, multi-site and multifactorial trial of hospital cleaning in the world,” Professor Graves said. “Its aim primarily was to investigate whether a change in cleaning practices was effective; but in reducing the 165,000 healthcare-associated infections in Australia each year.”

Multi-site and multifactorial trial of hospital cleaning

Professor Graves said the REACH (Researching Effective Approaches to Cleaning Hospitals) project; but introduced a bundle of cleaning initiatives, tailored to each hospital in the study; so to improve both routine and discharge hospital room cleaning. Hospital-wide promotion of the importance of cleaning in reducing infections; was undertaking to support a culture shift; but in the profile of environmental services staff, Professor Graves said.

“Cleaning was auditing using fluorescent marker technology. This system used gel dots, invisible to the naked eye, applied to surfaces. The dots resist dry abrasion and are removing only thorough cleaning technique,” he said. “Hospitals in the study improved their cleaning practices from 55 to 76% in bathroom areas and from 64 to 86% in bedroom areas.”

This resulted in a 37% reduction in the major healthcare-associated infection, vancomycin-resistance enterococci (VRE), and a 5.8% decrease overall in three types of infections. In contrast to previous research, the cleaning bundle development prioritizing; so evidence-based strategies that were easy to implement and lower cost, over newer expensive technologies. Overall, the cleaning bundle cost approximately $2,500 per 10,000 bed days to implement in participating hospitals.

The economic outcomes

The REACH cleaning bundle was successful at improving cleaning thoroughness and showed great promise in reducing vancomycin-resistant enterococci infections. It also demonstrated cost-savings and increased health benefits from infections prevented. The intervention is broadly applicable to cleaning in any hospital, throughout the continuum of care, as it does not solely focus on discharge cleaning. Future publication of the economic outcomes of the study will provide valuable information for decision makers about the potential for investing in future hospital cleaning initiatives.
