The aim was to assess the incidence of sink contamination by multidrug-resistant (MDR) Pseudomonas aeruginosa and Enterobacteriaceae, risk factors for sink contamination and splashing, and their association with clinical infections in the intensive care setting.
A prospective French multicentre study (1 January to 30 May 2020) including in each intensive care unit (ICU) a point-prevalence study of sink contamination, a questionnaire of risk factors for sink contamination (sink use, disinfection procedure) and splashing (visible plashes, distance and barrier between sink and bed), and a 3-month prospective infection survey.
Seventy-three ICUs participated in the study. In total, 50.9% (606/1191) of the sinks were contaminated by MDR bacteria: 41.0% (110/268) of the sinks used only for handwashing, 55.3% (510/923) of those used for waste disposal, 23.0% (62/269) of sinks daily bleached, 59.1% (126/213) of those daily exposed to quaternary ammonium compounds (QACs) and 62.0% (285/460) of those untreated; 459 sinks (38.5%) showed visible splashes and 30.5% (363/1191) were close to the bed (<2 m) with no barrier around the sink. MDR-associated bloodstream infection incidence rates ≥0.70/1000 patient days were associated with ICUs meeting three or four of these conditions, i.e. a sink contamination rate ≥51%, prevalence of sinks with visible splashes ≥14%, prevalence of sinks close to the patient's bed ≥21% and no daily bleach disinfection (6/30 (20.0%) of the ICUs with none, one or two factors vs. 14/28 (50.0%) of the ICUs with three or four factors; p 0.016).
Our data showed frequent and multifactorial infectious risks associated with contaminated sinks in ICUs.
评估耐多药（MDR）铜绿假单胞菌和肠杆菌科引起的水槽污染的发生率、水槽污染和溅水的危险因素，以及它们与重症监护环境中临床感染的关系。
这是一项前瞻性的法国多中心研究（2020 年 1 月 1 日至 5 月 30 日），包括每个重症监护病房（ICU）的水槽污染点患病率研究、水槽污染（水槽使用、消毒程序）和溅水（可见飞沫、水槽和床之间的距离和障碍物）危险因素的问卷调查，以及为期 3 个月的前瞻性感染调查。
73 个 ICU 参与了该研究。共有 50.9%（606/1191）的水槽被 MDR 细菌污染：仅用于洗手的水槽中，41.0%（110/268）被污染；用于废物处理的水槽中，55.3%（510/923）被污染；每天用漂白剂消毒的水槽中，23.0%（62/269）被污染；每天暴露于季铵化合物（QAC）的水槽中，59.1%（126/213）被污染；未处理的水槽中，62.0%（285/460）被污染；459 个水槽（38.5%）出现可见溅水，30.5%（363/1191）靠近病床（<2 m），水槽周围无障碍物。与每 1000 个患者日发生≥0.70 例耐多药相关性血流感染的 ICU 相关的条件是：水槽污染率≥51%，可见溅水的水槽发生率≥14%，靠近患者病床的水槽发生率≥21%，且无每日漂白消毒（30 个 ICU 中，无、一个或两个因素者 6/30（20.0%），三个或四个因素者 14/28（50.0%）；p=0.016）。
我们的数据显示，ICU 中污染水槽与频繁和多因素的感染风险有关。
