Sanitary appliance: comparative study of automated and manual cleaning and disinfection processes

Objective: To compare the results of manual and automated cleaning and disinfection of Sanitary Appliance (US). Method: A descriptive experimental study, carried out by means of microbiological cultures of appliance used by patients bedridden in a hospitalization unit of a hospital located in the south of Brazil. Thirty three samples were collected after the cleaning and disinfection processes were carried out, eleven for each of the three methods available: automated, manual with and without supervision for microbiological evaluation. Results: In the automated process, pathogenic microorganisms of epidemiological relevance was now here to be found in the experiment. In the manual, in both processes performed, according to protocol established by the Institution with and without supervision, there was growth of pathogenic microorganisms. Conclusion: Therefore, in this study we conclude that the automated method for cleaning and disinfection has been shown to be safer for use in healthcare. The results obtained in the manual method do not confer safety. It is suggested that studies be carried out with references trains with controlled contamination.
