Health service organisations need to monitor antimicrobial use and resistance as a part of the National Safety and Quality Health Service Standards.
Antibiograms are tables of antimicrobial susceptibilities. They are used to inform local empirical antimicrobial recommendations and formulary management. Antibiograms should be available to clinicians and groups who are responsible for local antimicrobial therapy guidelines.
In 2012 and 2013, the Commission developed a specification for hospital-level cumulative antibiograms for local surveillance of antimicrobial resistance. Specification of both the clinical and technical elements of cumulative antibiograms will support antimicrobial prescribing and antimicrobial stewardship in general. Specification of the cumulative antibiogram will also support national surveillance, mapping and monitoring of antimicrobial resistance.
Specification for Hospital Cumulative Antibiograms (this specification is currently being updated)
The first expert roundtable in 2012 was to introduce the Commission’s proposal on the hospital-level cumulative antibiogram, and to understand current approaches to monitoring antimicrobial resistance.
Outcomes from the roundtable were that standardised antibiograms should:
The second expert roundtable reviewed and commented on the draft specification for the hospital-level cumulative antibiogram.
Participants included members from each state and territory, private hospitals, microbiology and laboratory sectors. Participants provided feedback on the draft and gave examples of antibiograms that were incorporated into the final draft.
The Expert Roundtable recommended that the Specification for Hospital-Level Cumulative Antibiograms be produced for each calendar year. The antibiograms should summarise susceptibilities of individual patients’ first isolates separately from non-urine (all other body sites), urine and blood isolates (if there are sufficient numbers to provide statistically reliable data).
Specifically, it was recommended that:
