M121-1

Urine catheter: Enterococcus faecium (VRE) – Shipped May 2012

HISTORY

The challenge was sent to category A, B, and C laboratories. The sample was a simulated catheter urine obtained from a 65 year old female in-patient with symptomatic UTI.

Participants were expected to isolate, report colony count, and identify VRE. Antibiotic susceptibility and notification to infection control were also expected.

MAIN EDUCATIONAL POINTS from M121-1

  1. VRE are a common cause of nosocomial UTI, especially in catheterized patients.
  2. The lab report should state clearly that VRE has been isolated. Reporting of an Enterococcus species with resistance to vancomycin listed among several other antimicrobial susceptibility results may lead to misinterpretation.
