Sink drains of six intensive care units (ICUs) were sampled for screening contamination with extended-spectrum β-lactamase-producing Enterobacteriaceae (ESBLE). A high prevalence (59.4%) of sink drain contamination was observed. Analysing the data by ICU, the ratio 'number of ESBLE species isolated in sink drains/total number of sink drains sampled' was highly correlated (Spearman coefficient: 0.87; P = 0.02) with the ratio 'number of hospitalization days for patients with ESBLE carriage identified within the preceding year/total number of hospitalization days within the preceding year'. Concurrently, the distribution of ESBLE species differed significantly between patients and sink drains.
对 6 个重症监护病房（ICU）的水槽排水管进行采样，以筛查是否存在产超广谱β-内酰胺酶的肠杆菌科（ESBLE）污染。观察到水槽排水管污染的高患病率（59.4%）。通过 ICU 对数据进行分析，“水槽排水管中分离出的 ESBLE 种类数/采样的水槽排水管总数”的比值与“前一年中携带 ESBLE 的患者的住院天数/前一年的总住院天数”的比值呈高度相关（Spearman 系数：0.87；P = 0.02）。同时，ESBLE 种类在患者和水槽排水管之间的分布差异显著。
