Identification of carbapenem-resistant organism (CRO) contamination of in-room sinks in intensive care units in a new hospital bed tower

Published on 02/21/2024 | by Waterline Admin

Warren BG, Smith BA, Barrett A, Graves AM, Nelson A, Gettler E, Lewis SS, Anderson DJ. Infect Control Hosp Epidemiol. 2024 Jan 19:1-8. doi: 10.1017/ice.2023.289. Epub ahead of print. PMID: 38239018.

Highlights

  • The origins and timing of inpatient room sink contamination with carbapenem-resistant organisms (CROs) are poorly understood.
  • 1,638 total environmental cultures were obtained and 2,814 patients were admitted to study units while sink sampling occurred.
  • 9 sinks (41%) in unit A became contaminated with CRO by month 10, and all 26 sinks became contaminated in unit B by month 7.
  • 299 CRO isolates were recovered; the most common species were Enterobacter cloacae and Pseudomonas aeruginosa.
  • CRO contamination of sinks in 2 newly constructed ICUs was rapid and cumulative and the study emphasises the need for prevention strategies to mitigate contamination of hands and surfaces from CRO-colonised sinks.

    Grime Scene

    ANNOUNCING OUR NEW GRIME SCENE COMPETITION:

    Following on from the successful Grime Scene competition, we have decided to continue the theme for another year, but with a twist. This year, we are asking for photographs of the grimiest pictures you can find accompanied with another photograph of how the ‘scene’ has been improved by your maintenance or cleaning.


    We will display the photographs in each of the Waterline editions throughout 2024. The ‘most improved’ picture will be chosen by WMSoc members via an online vote. The winner will receive a £25 Amazon Gift Voucher after the Winter 2024/25 edition has been published.


    Please send your photographs to:

    Lovibond MD640 Photometer (PTSA & Fluorescein capable)

    Product Spotlight Drop Test Kits

    How many times have you heard … ‘we’re not sure what the system volume is’. A common problem which can be expensive - wasting chemical over dosing, or underdosing so the treatment is ineffective (i.e. shock dosing a biocide). The MD640 photometer has PTSA & Fluorescein capability built in. Simply use our System Checkers to add to an unknown system and read a PTSA or Fluorescein levels to accurately identify the system volume.

    The Hydrosense PRO range

    Hydrosense

    The Hydrosense PRO range pioneers Legionella pneumophila detection, the cause of over 97% of Legionnaires’ disease outbreaks, by identifying all the serogroups 1-15 of this dangerous Legionella species. This easy-to-use, highly sensitive test uses unique filtration, offering a three-line test result that distinguishes between serogroup 1 and serogroups 2-15 within 25 minutes. The water test has a level of detection of 100 CFU/L and swab tests detect 200 CFU per swabbed area, providing crucial, rapid insights for water safety management.
