In primary and secondary care, in order to obtain authorisation, contact the duty consultant microbiologist in Raigmore via the laboratory on Ext 4206 (out of hours, via switchboard) or the infectious diseases physician via switchboard.

Secondary care: a code will be provided and must be written:

  • in the notes as part of the Micro/ID discussion,
  • on the drug chart beside the antimicrobial in question and 
  • on the ward order form before sending to Pharmacy.
  • This code is checked by Pharmacy staff and, if appropriate, the antimicrobial is supplied to the ward.
  • In the absence of a valid authorisation code, no antimicrobial will be supplied, and the ward pharmacist will contact the prescriber who is welcome to discuss with a consultant microbiologist.     

Primary care: 

These antimicrobials should only be used following discussion with, or on the advice of, an infection specialist. This should be recorded in the patient notes.

Argyll & Bute HSCP:
