  • Background: While daily disinfection of high-touch surfaces reduces microbial contamination of the environment and healthcare workers' hands and may reduce pathogen transmission, previous studies suggest that daily cleaning and disinfection is not done consistently or effectively. We assessed the effectiveness of daily cleaning of high-touch surfaces in patient rooms and barriers to cleaning experienced by Environmental Service (EVS) workers.

    Methods: ATP concentrations present on 6 surfaces in 24 occupied patient rooms were measured before and after daily cleaning on 17 inpatient units (8 ICUs and 9 non-ICUs) in 5 acute care hospitals using the 3M Clean-Trace system. The threshold for a clean surface was a relative light unit (RLU) value ≤250. An anonymous, voluntary survey of EVS workers in the same hospitals assessed knowledge, attitudes, and practices (KAP) related to daily cleaning.

    Results: Median RLU values for the 4 surfaces near the patient bed exceeded the threshold for cleanliness both before and after cleaning (Figure). In contrast, median values for the 2 bathroom surfaces exceeded the threshold prior to cleaning but were significantly lower and below the threshold afterwards. Among 289 survey respondents (response rate 44%), 93% reported often or always using disinfectant on surfaces around the patient bed during daily cleaning and 91% agreed that they had been taught how to perform daily cleaning properly. However, 40% reported they often/always avoided cleaning near patients to avoid disturbing them and 40% reported that the over bed table was often/always too cluttered to clean. Respondents identified bed rails (40%) and over bed tables (32%) as most difficult to access for daily cleaning.

    Conclusion: Quantitative data found that high-touch surfaces around patient beds were not cleaned as effectively as bathroom surfaces during daily cleaning. While most participants felt they were adequately trained, the KAP survey identified several barriers that may explain these observations. Clutter, constrained access, and concerns about disturbing patients seemed to prevent effective cleaning of surfaces close to patients. Interventions that address these barriers may improve the effectiveness of daily cleaning and patient safety.
