Assessment of Soiling on Highly Touched Clinical Surfaces in Intensive Care Units

AIM: The aim of this study is to evaluate highly touched clinical surfaces using visual inspection methods and adenosine triphosphate by bioluminescence to identify soiling in intensive care units.

METHOD: Descriptive, cross-sectional study carried out in three intensive care units located in Belo Horizonte, MG, Brazil. Data collection included 142 assessments of environmental surfaces. For data analysis, the Pareto diagram and descriptive statistics were used through measures of central tendency.

RESULTS: The visual inspection identified dirtiness in the infusion pump, alcohol dispenser, and telephone. The surface that showed a high level of contamination by organic matter identified by the adenosine triphosphate bioluminescence test was the telephone, with a median of 1012 RLU/cm2 (±348.8).

CONCLUSION: The surface evaluation methods used in the intensive care units made it possible to identify dirt on surfaces highly touched by hands, reinforcing the need for investments in training and audits in the process of cleaning and disinfecting surfaces.
