This study aimed to describe the contamination of sink drains (SDs) with carbapenemase-producing Enterobacterales (CPE) in three intensive care units (ICUs), and to assess the risk of transmission to hospitalized patients. All SDs were sampled monthly for CPE screening by culture. Rectal screening for CPE carriage was conducted weekly for hospitalized patients. CPE were isolated from 22% of SD samples. Some SDs remained colonized with the same strain for several months. No CPE acquisition occurred among hospitalized patients during the study. Certain strategies, such as systematic sampling of SDs in ICUs for screening for contamination by CPE, should be discouraged apart from during outbreaks.
本研究旨在描述三个重症监护病房（ICU）中产生碳青霉烯酶的肠杆菌科细菌（CPE）对水槽排水口（SD）的污染情况，并评估其传播至住院患者的风险。每月对所有SD进行采样，通过培养进行CPE筛查。对住院患者每周进行直肠CPE携带情况筛查。22%的SD样本中分离出CPE。一些SD在数月内一直被同一菌株定植。在研究期间，住院患者中未发生CPE感染。除疫情期间外，应避免采取某些策略，如对ICU中的SD进行系统采样以筛查CPE污染。
