Organosilane will be sprayed on the surfaces, using an atomizer. When the environment has been completely covered (i.e., when all surfaces and equipment have a slightly damp film), we will proceed with the second phase of the disinfection of all heavily touched surfaces. surfaces of the bed, with a microfiber cloth with organosilane.

The control group will perform standard cleaning and disinfection of the beds and the environment according to their previous protocols, using the usual products.

We will collect environmental samples from 4 surfaces highly touched by the patient, health team and family (bed rails, monitor and infusion pump buttons, meal table or procedure table, and IV drip stand) before and after the intervention. (end of the 6 months). For analysis of the environmental samples, characterization of the density and microbiological profile of biofilms on the different surfaces of the ICU beds will be performed using large-scale DNA sequencing techniques associated with bioinformatics analysis.
