Safety and Quality > Our Work > Safety in E-Health > Hospital-Level Cumulative Antibiogram Expert Roundtable, 14 May 2013

Purpose

The Expert Roundtable was convened to review and comment on the draft specification for the Hospital-Level Cumulative Antibiogram. The roundtable was represented by members from each jurisdiction, private hospitals, microbiology and laboratory sectors. Members provided feedback on the draft and gave examples of antibiograms that have been incorporated into the final draft.

Outcomes

The specification for Hospital-Level Cumulative Antibiograms recommend tabulated cumulative antibiograms be produced for each calendar year. They should summarise susceptibilities of individual patient’s 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 is recommended:

  • for non-urine isolates for each calendar year to report susceptibilities for at least the five most commonly isolated species, regardless of numbers isolated, and to report all isolates where the number tested is greater than 30
  • for urine isolates, to report each calendar year at least the three most commonly isolated species with their susceptibilities, regardless of numbers isolated, and to report all isolates where the number tested is greater than 30, and
  • to report susceptibilities for any species isolated more than 30 times in blood cultures.

It is also recommended that the frequency of certain specified microorganism-antimicrobial susceptibility combinations (“signal resistances”) should be listed annually. The cumulative antibiogram should include emergency department isolates and may include those from outpatients.
