To describe factors in an outbreak of multidrug-resistant (MRE) in an intensive care unit (ICU) over a 20-month period including the likely contribution of cockroaches to the outbreak.
This is a retrospective descriptive study.
ICU in an urban hospital.
All patients admitted to the ICU during the 20-month outbreak period were included in the study.
Infection prevention interventions included contact isolation, hand hygiene, dedicated patient equipment, environmental cultures, and pest control.
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.
Insects have a potential role in transmission of pathogens in hospitals and their role should be considered when outbreaks are being investigated.
描述重症监护病房（ICU）在20个月期间耐多药肠球菌（MRE）暴发的相关因素，包括蟑螂在此次暴发中可能起到的作用。
这是一项回顾性描述性研究。
一家城市医院的ICU。
在20个月暴发期内入住该ICU的所有患者均纳入研究。
感染预防干预措施包括接触隔离、手卫生、专用患者设备、环境培养及虫害控制。
确定有25例患者被MRE定植或感染。脉冲场凝胶电泳证明了暴发菌株与在蟑螂体内发现的菌株具有相关性。在增加虫害控制措施之前，标准的感染预防干预措施对此次暴发没有影响。一旦实施了额外的虫害控制措施，暴发就结束了。
昆虫在医院病原体传播中可能发挥作用，在调查暴发事件时应考虑其作用。
