Patient-care items can serve as a source or reservoir for healthcare-associated pathogens in hospitals. We reviewed healthcare- associated outbreaks from medical equipment and provide infection prevention recommendations. Multiple healthcare-associated outbreaks via a contaminated patient-care item were identified, including infections with multidrug-resistant organisms. The type of patient care items implicated as a fomite causing healthcare-associated infections (HAIs) has changed over time. Patient populations at risk were most commonly critically ill patients in adult and neonatal intensive care units. Most fomite related healthcare-associated outbreaks were due to inappropriate disinfection practices. Repeated healthcare-associated outbreaks via medical equipment highlight the need for infectious disease professionals to understand that fomites/medical devices may be a source of HAIs. The introduction of new and more complex medical devices will likely increase the risk that such devices serve as a source of HAIs. Assuring appropriate cleaning and disinfection or sterilization of medical equipment is necessary to prevent future fomite-associated outbreaks.
患者护理用品可成为医院中医疗相关病原体的来源或储源。我们回顾了与医疗器械相关的暴发事件，并提供了感染预防建议。已确定多起通过污染的患者护理用品引发的医疗相关暴发事件，包括耐多药生物体感染。过去，作为导致医疗相关感染（HAI）的病原体的患者护理用品类型已发生变化。感染风险最高的患者人群通常是成人和新生儿重症监护病房中的重症患者。大多数与污染物相关的医疗相关暴发事件是由于消毒措施不当所致。通过医疗设备反复发生的医疗相关暴发事件，突显了传染病专家需要了解污染物/医疗器械可能是 HAI 的来源。新型且更复杂的医疗器械的引入可能会增加这些设备成为 HAI 来源的风险。确保对医疗器械进行适当的清洁、消毒或灭菌，是预防未来因污染物相关暴发事件的必要措施。
