Bacterial resistance in hospital settings represents a growing public health challenge, especially in intensive care units (ICUs), where the intensive use of antimicrobials favors the emergence and spread of multidrug-resistant microorganisms. This study aims to analyze, through an integrative literature review, the occurrence, main types, and resistance mechanisms of multidrug-resistant bacteria in hospital ICUs. Eighteen studies published between 2020 and 2025 were analyzed, identifying Acinetobacter baumannii and Klebsiella pneumoniae as the most prevalent, followed by Pseudomonas aeruginosa, Staphylococcus aureus (MRSA), Enterococcus faecium (VRE), and carbapenem-resistant Enterobacter (CRE). The results reinforce the importance of infection control policies, rational use of antimicrobials, and continuous epidemiological surveillance as essential strategies to contain bacterial resistance in critical environments.
