Roles of clinical microbiology in hospital environmental cleaning and disinfection: a narrative review

Young Ah Kim · Annals of Clinical Microbiology · 2024

Purpose: This narrative review examines the pivotal role of clinical microbiology in environmental cleaning and disinfection within healthcare facilities. With an increasing focus on infection control, particularly regarding multidrug-resistant organisms (MDROs), the review explores disinfection strategies, monitoring methods, and best practices, including recent recommendations from the Korea Disease Control and Prevention Agency. Current content: MDROs such as methicillin-resistant Staphylococcus aureus, vancomycinresistant enterococci, and carbapenem-resistant gram-negative bacteria are significant contributors to healthcare-associated infections (HAIs). These organisms persist on hospital surfaces, posing a risk of transmission. There are various disinfection modalities for noncritical surfaces (e.g., bedrails, floors) detailing the advantages and limitations of common disinfectants, including quaternary ammonium compounds, hydrogen peroxide, and sodium hypochlorite. It is efficient to use self-disinfecting surfaces coated with heavy metals and no-touch disinfection technologies, such as ultraviolet (UV)-C light and vaporized hydrogen peroxide. Clinical microbiologists are res
