Brief ReportMultisite evaluation of environmental cleanliness of high-touch surfaces in intensive care unit patient rooms
Section snippets
Methods
A prospective intensive care unit (ICU) intervention study assessed 5 high-touch surfaces in 50 rooms in each of 4 countries in 2015 and 2016. The efficacy of the discharge cleaning and disinfection regimens was evaluated by measuring ATP levels, microbiologic contamination, and RSM removal. The rooms were chosen based on convenience sampling.
Standard terminal cleaning and disinfection procedures for ICU patient rooms were collected and recorded for each of the 4 sites (Table 1). The 3M
Results
Baseline characteristics relevant for cleaning and disinfection of ICUs in Brazil, Canada, the Netherlands, and the United States are provided in Table 1. A variety of detergents, disinfectants, and combinations were used at the different study sites. Because it is an active compound, quaternary ammonium compounds were most frequently used (3 out of 4 sites) followed by hydrogen peroxide (2 out of 4 sites). During the preintervention and intervention periods, significant differences between
Discussion
In the context of increasing bacterial multidrug resistance the absence of a global cleaning and disinfection guideline is striking. In this multisite evaluation of environmental cleanliness of high-touch surfaces in ICU patient rooms, we were able to demonstrate large variations in cleaning and disinfection protocols, detergents and disinfectants used, and the resultant outcomes. Monitoring of staff cleaning compliance using rapid methods such as RSM or ATP with staff feedback can ensure

High-touch surfaces disinfection compliance in a COVID-19 intensive care unit
2023, American Journal of Infection ControlCitation Excerpt :A multicenter study of ICUs evaluated the efficacy of terminal cleaning and disinfection by measuring Adenosine triphosphate (ATP) levels, colony-forming units, and reflective surface marker removal. The educational intervention was composed of ATP measurements and offered feedback based on the quality of the surface disinfection and cleaning processes.10 In the present study, except for the mechanical ventilator disinfection, the overall disinfection compliance significantly improved, probably because the ventilators are minimally manipulated by the nursing team.
Stakeholders’ perceptions of family-centred care in the intensive care unit: An associative group analysis
2021, Intensive and Critical Care NursingCitation Excerpt :Nurses indicated the lack of space around ICU beds influenced the cleanliness of the environment. This is vitally important for both patients and their families because of the increasing incidence of multidrug resistant micro-organisms (Hopman et al., 2018; Mahomed et al., 2018). Nurses also indicated that noise levels might negatively influence ideal FCC.
Assessment of a novel antimicrobial surface disinfectant on inert surfaces in the intensive care unit environment using ATP-bioluminesence assay
2020, American Journal of Infection ControlCitation Excerpt :A recent multisite evaluation of environmental cleanliness of high-touch surfaces in the ICU demonstrated large variations in cleaning/disinfection protocols and product selection. The authors found that staff cleaning compliance using rapid methods such as relative surface marker assessment or adenosine triphosphate (ATP) bioluminescence with staff feedback was effective in assuring optimal disinfection of high-touch surfaces in the ICU.11 The authors suggested that total aerobic culture counts on high-touch surfaces provided limited value for routine monitoring of cleanliness.
