With aging of the population in the United States, there are more people in long-term care facilities than in hospitals. Nursing home residents have a high prevalence of colonization with multidrug-resistant organisms (MDROs). A shared environment with vulnerable patients can facilitate intra- and inter-facility transmission of MDROs. The aim of this paper is to examine the role of the nursing home environment in MDRO transmission and provide infection prevention strategies.
We searched the published literature and reviewed selected articles on contamination, transmission, and infection associated with the nursing home environment.
Nursing home residents were frequently colonized with MDROs, leading to contamination of the surrounding environment with the same pathogen. Surface contamination with MDROs was common in nursing home patient rooms, and to a substantial but lesser frequency in common rooms. Shared rooms were a risk factor for MDRO transmission between patients.
Since outbreaks and infections via the environmental contamination cause substantial burden of morbidity and mortality in the nursing home residents, it is essential for healthcare personnel to recognize the role of the nursing home environment in infection transmission and adhere to the current infection prevention guidelines for cleaning and disinfection of environmental surfaces.
随着美国人口老龄化，长期护理机构中的人数超过了医院。疗养院居民具有很高的多药耐药菌（MDRO）定植率。脆弱患者的共享环境可促进 MDRO 的在机构内和机构间传播。本文旨在探讨疗养院环境在 MDRO 传播中的作用，并提供感染预防策略。
我们检索了已发表的文献，并回顾了有关疗养院环境与 MDRO 传播和感染相关的选定文章。
疗养院居民经常定植 MDRO，导致周围环境受到相同病原体的污染。MDRO 在疗养院患者病房的表面污染很常见，在公共房间也有一定但频率较低的污染。共用房间是患者之间 MDRO 传播的危险因素。
由于环境污染导致的暴发和感染给疗养院居民带来了大量的发病率和死亡率负担，因此医护人员必须认识到疗养院环境在感染传播中的作用，并遵守当前关于环境表面清洁和消毒的感染预防指南。
