摘要
目的:描述重症监护病房(ICU)在20个月内爆发耐多药阴沟肠杆菌(MRE)疫情的因素,包括蟑螂对疫情可能造成的影响:设计:这是一项回顾性描述性研究:地点:一家城市医院的重症监护室:患者:在疫情爆发的 20 个月期间入住重症监护室的所有患者均纳入研究范围:感染预防干预措施包括接触隔离、手部卫生、病人专用设备、环境培养和虫害控制。脉冲场凝胶电泳显示,疫情菌株与蟑螂体内发现的菌株具有相关性。在加入害虫控制之前,标准的 IP 干预措施对疫情没有影响。一旦采取了额外的害虫控制措施,疫情就结束了:昆虫在医院病原体传播中具有潜在作用,在调查疫情爆发时应考虑昆虫的作用。
Invasion of superbugs: Cockroach-driven outbreak of multidrug-resistant Enterobacter in an ICU.
Objective: To describe factors in an outbreak of multidrug-resistant Enterobacter cloacae (MRE) in an intensive care unit (ICU) over a 20-month period including the likely contribution of cockroaches to the outbreak.
Design: This is a retrospective descriptive study.
Setting: ICU in an urban hospital.
Patients: All patients admitted to the ICU during the 20-month outbreak period were included in the study.
Interventions: Infection prevention interventions included contact isolation, hand hygiene, dedicated patient equipment, environmental cultures, and pest control.
Results: 25 patients were identified as being colonized or infected with MRE. Relatedness of the outbreak strain and strains found in cockroaches was demonstrated by pulse field gel electrophoresis. Standard IP interventions did not have an impact on the outbreak until pest control was added. Once additional pest control measures were put in place, the outbreak ended.
Conclusions: Insects have a potential role in transmission of pathogens in hospitals and their role should be considered when outbreaks are being investigated.
