The hospitals of Dracena (SCD) and Presidente Venceslau (SCPV) are the largest hospitals in the west region of the state of São Paulo and, due to the high number of patients seen in these hospitals, this work aimed to research multidrug-resistant bacteria in the ICU bed environment of these two hospitals. This is a descriptive and transversal observational research, where samples were collected from the environment of the 10 ICU beds of the SCD and the 10 ICU beds of the SCPV, in regions with frequent contact with hands and fomites. Isolated grown colonies were identified at the genus and species level. Antimicrobial susceptibility testing was performed following the recommendations of the Clinical and Laboratory Standards Institute (2021). Forty-five bacteria were isolated, 25 from SCD and 20 from SCPV. Most bacteria were Gram-negative bacilli (N = 27; 60%), followed by Staphylococcus aureus (N = 12; 26.7%) and Enterococcus faecalis (N = 6; 13.3%). Bacteria were found in the environment of the 10 ICU beds of the SCD and in nine of the 10 ICU beds of the SCPV. Most of the isolated bacteria showed resistance to several antimicrobials, being identified 34 MR, being 23 of SCD and 11 of SCPV. The isolates were grouped into seven groups of resistance phenotype, showing a possible clonal dispersion. The presence of MR in the hospital environment generates permanent concern, since they can infect hospitalized patients, especially after a breach of the protocol to prevent the transmission of infectious agents. This work will contribute to the improvement of hygiene protocols, offering more security to users of these hospitals.
