A Scoping Review of Fomites in Surgery Theaters and Intensive Care Units of Healthcare Facilities in Middle-Income Countries Public
Peng, Tzuhsuan (Spring 2021)
Abstract
Background: Health care-associated infections (HCAIs) pose a substantial burden to healthcare systems and patient safety worldwide. This burden is even more critical in low- and middle-income countries (LMICs). While surgical site infection remains the most common type of HCAIs, critically ill patients in the intensive care unit (ICU) are also subject to HCAIs. A higher HCAI rate in LMICs is attributed to inadequate infection prevention and control (IPC) at healthcare facilities. Fomites, or inanimate objects that can carry pathogens, are often overlooked in IPC and decontamination instruction. As a result, this thesis aims to search the scientific literature to identify potential fomites in surgery theaters and ICUs that may serve as sources of pathogens related to HCAIs in order to inform and improve the World Health Organization’s IPC guidelines.
Methods: A scoping review was conducted to search PubMed, Embase, and CINAHL databases for articles published before February 2021, written in English, and available for abstract. Four main keywords were used for the database search: HCAI, ICU or surgery theater, fomite, and names of middle-income countries. Abstract and title were screened first using inclusion criteria, and subsequently, full texts were evaluated for final inclusion based on exclusion criteria.
Results: The initial database search yielded 241 articles. Of the 45 articles that satisfied the inclusion criteria, eight and 37 studies were carried out in surgery theaters and ICUs, respectively. Multiple medical equipment and supplies (laryngoscopes, suction tips, trolleys, incubators, beds, etc.), environmental surfaces (floor, sinks, tables, operation lamps, etc.), and personal items (mobile phones, clothes, etc.) were found as potential fomites that may threaten HCAI prevention and control. The main transmission routes of pathogens from a fomite to a patient were direct contact and indirect contact through health workers' hands or gloves that touched the fomite.
Conclusions: Various fomites that may be involved in HCAIs were reported. Recommendations for the World Health Organization’s IPC guidelines include monitoring bacterial resistance to disinfectants; coming to a consensus regarding the reuse of single-use medical devices; developing protocols for regular cleaning of personal items; and developing a policy on restricting mobile phone usage in theatres and ICUs.
