AbstractThis narrative review evaluates the evidence regarding the protection offered by isolation gowns, approaches to imparting antimicrobial activity to gowns, and the environmental impacts of gown use, particularly during the COVID-19 pandemic. We conducted a search of the Medline, PubMed, and Google Scholar databases for articles published between January 1, 2019 to February 20, 2024. We found that current standards pertaining to isolation gowns might be irrelevant to the protection of healthcare workers from pathogen transmission, as they focus primarily on fluid barrier resistance values that are not reflective of all transmission conditions in hospitals. Although most available isolation gowns are disposable, reusable gowns could offer greater barrier protection and are more environmentally sustainable. Several techniques have been studied for their ability to impart antimicrobial properties to isolation gowns, extending their lifespan and reducing environmental impacts. However, evidence of the effectiveness of such techniques in clinical settings is scarce. We advocate for standardised guidelines inclusive of common pathogen survival tests, comfort, and durability, which reflect the actual infection risks encountered by healthcare workers, to improve the safety and efficacy of isolation gowns in hospital settings. Further research into the clinical effectiveness of antimicrobial gowns and their long-term implications on the environment is also warranted.Copyright © 2024 British Journal of Anaesthesia.
