摘要：A large single-strain outbreak of vancomycin–resistant Enterococcus faecium (VREF) vanB occurredin Royal Perth Hospital from July to December 2001. When a VREF–carrying patient was discoveredon a ward, all patients on the ward were screened with rectal swabs. A total of 172 patients werecolonised, four with infections, but no deaths were attributable to VREF. The number of rectal swabsrequired to detect each carrier was recorded. On average four rectal swabs, each collected onseparate days, were needed to detect more than 90 per cent of the 172 VREF carriers who wereepidemiologically linked to the Royal Perth Hospital outbreak. An electronic alert system (Micro-Alert)was used to identify ward contacts of VREF carriers and enabled those who had not been screenedbefore discharge to be followed-up and screened. Ninety-six contacts were actively followed-up inOctober 2001 and 32 (33.3%) were found to be VREF carriers. From 28 September 2001 to 30 April2002, a total of 1,977 ward contacts were screened after discharge from hospital and 54 (2.73%)were found to be carrying VREF. We conclude that during single-strain outbreaks of vancomycin-resistant enterococci in hospitals, patient contacts need to be screened on more than three occasionsin order to detect most of the carriers and control the outbreak. Secondly, electronic labelling andactive follow-up of patients with VREF resulted in a significant number of carriers being detected whootherwise posed a risk of initiating further outbreaks in hospitals if they were readmitted
