Multidrug resistant Acinetobacter screen (multidrug resistant resistance)

Microbiology

Notes

• Multidrug resistant Acinetobacter species are defined as strains showing resistance to quinolones, cephalosporins, gentamicin, co-amoxiclav and piperacillin/tazobactam. They may also be resistant to carbapenems and colistin.
• Currently, screening for these organisms is only routinely done on the Intensive Care Units at both CGH and GRH sites when a patient is transferred from an ICU outside of the Trust.
• The following sites should be screened:
  • Nose
  • Throat
  • Groin
  • Urine (MSU or CSU)
  • Sputum (if productive)
  • Stool (or rectal swab)
  • Wounds
• Screens should be performed on admission to the Critical Care Unit. Any positive results should be discussed with the ICT who will help direct any further testing.
• For further guidance and information please see Infection Control policy.
