Studies indicate that the hospital has an important role in transmission of various pathogens. To minimize the spread of these microorganisms in hospitals, they proposed various forms of disinfection, however diversity and effectiveness of these methods are varied. Thus, this study aimed to understand the associations and approaches that have been reported in recent years on microorganisms control by disinfectants in the hospital environment, thus enabling the search for new strategies and/or implementation of conducts already performed in other hospitals. In this article they performed a systematic review on the topic, in accordance with the preferred reporting items for systematic reviews and meta-analyzes-PRISMA. Articles were selected published between the years 2012-2016 present in the PubMed database. The data demonstrate that reviews many conventional methods may be flawed (10%), or may not be able to reduce the number of microorganisms (30%). The most frequently related microorganisms were Clostridium difficile (20%), methicillin-resistant Staphylococcus aureus (40%), or Enterococcus resistant to vancomycin (20%). There was no evidence statistical differences for a tendency to exchange the conventional methods, however the management was highlighted by 50% of the disinfection process. But our approach has enabled better understanding of mechanisms linked to environmental disinfection process of pathogenic microorganisms, thus pointing to coherent strategies in disinfection processes, which have benefits with the reduction of major causative agents of nosocomial infections and thus with decreasing nosocomial diseases.
