Les infections nosocomiales sont un problème courant dans les établissements de santé. Elles sont causées par des micro-organismes présents dans l’environnement et entraînent des risques pour la santé et des contraintes financières. Malgré les efforts déployés pour réduire les IAS, le rôle de l’environnement physique dans la réduction des IAS n’est pas entièrement compris. Cette revue de la littérature visait à identifier les variables de l’environnement physique contribuant aux IAS.
BACKGROUND: Healthcare-Associated Infections (HAIs) are a common issue in healthcare settings, caused by environmental microorganisms, leading to health risks and financial strain. Despite efforts to reduce HAIs, the role of the physical environment in reducing HAIs is not fully understood. This literature review aimed to identify physical environment variables contributing to HAIs. METHODS: A literature search was conducted in scientific databases between 2016 and 2022 using keywords associated with infections and physical environment variables. After screening retrieved articles for eligibility, the articles were analyzed for relevant environmental and infection variables. RESULTS: Out of 145, 27 articles were identified. The findings were grouped into eight categories, including layout design, surfaces, behavior, lighting, Internet of Things (IoT), materials, airflow, and air quality, with sub-themes in each group. CONCLUSION: The physical environment in healthcare facilities plays a crucial role in reducing and preventing the spread of HAIs. Proper design and construction of healthcare buildings, including ventilation and air conditioning systems, help prevent infection spread between functional areas. Antimicrobial materials, cleaning and disinfection protocols, and personal hygiene practices, such as hand hygiene, are key factors in infection control. The positioning of hand hygiene stations is also essential to improve compliance among healthcare professionals.
