Sink drain contamination with extended-spectrum-beta-lactamase-producing Enterobacteriaceae (ESBLE) in intensive care units: strong correlation to the ESBLE colonization pressure in patients but not same species

Kempf, M. EveillardSummarySink drains (SD) of six intensive care units (ICUs) were sampled for screening contamination with extended-spectrum beta-lactamase-producing Enterobacteriaceae (ESBLE). A high prevalence (59.4%) of SD contamination was observed. Analyzing the data by ICU, the ratio “number of ESBLE species isolated in SD/total number of SD sampled” was strongly correlated (Spearman coefficient, 0.87; P = .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 was strongly different between patients and SD.
