A systematic approach to improving antimicrobial use, with a view to improving clinical outcomes and minimising adverse events relating to their use
Six monthly antimicrobial utilisation reports
In addition to the six monthly reports below, National Antimicrobial Utilisation Surveillance Program (NAUSP) also produces detailed annual reports showing usage of an expanded number of antimicrobials both nationally and in individual Australian public and private hospitals in a de-identified manner.
NAUSP definitions
Prior to January 2021, total-hospital acute usage rates included usage in the emergency department and operating theatres. Usage in these areas will now be reported separately relative to patient presentations (replacing occupied bed days as a measure of patient activity), and are not included in total-hospital (or non-Critical Care) from January 2021.
National aggregated reports
Dec 2023 to Dec 2025
This 2-year longitudinal report includes aggregated usage by all contributors for both total hospital use and Critical Care (including Intensive Care and High Dependency Units) use.

Benchmarking reports by state/territory (total acute usage rates, excluding emergency and theatre)
Jul 2025 to Dec 2025
These six-monthly reports allow contributors to compare their usage of each antibacterial class with other hospitals within their state or territory.
- New South Wales and ACT with hospital data de-identified (PDF 343KB)
- Queensland and Northern Territory with hospital data de-identified (PDF 383KB)
- South Australia with hospital data de-identified (PDF 318KB)
- Victoria with hospital data de-identified (PDF 366KB)
- Western Australia with hospital data de-identified (PDF 363KB)
- Tasmania with hospital data de-identified (PDF 310KB)
Benchmarking reports by state/territory (Emergency Department)
Jul 2025 to Dec 2025
For hospitals able to submit Emergency Department (ED) usage data, these reports allow contributors to benchmark their ED usage rates with other hospitals in their state/territory.
- New South Wales and ACT emergency department benchmarking report (PDF 316KB)
- Queensland and Northern Territory emergency department benchmarking report (PDF 344KB)
- South Australia emergency department benchmarking report (PDF 257KB)
- Victoria emergency department benchmarking report (PDF 343KB)
- Western Australia emergency department benchmarking report (PDF 310KB)
- Tasmania emergency department benchmarking report (PDF 278KB)
Benchmarking reports by peer group (Critical Care Unit)
Jul 2025 to Dec 2025
For hospitals able to submit usage data for their Critical Care Unit, these reports allow contributors to benchmark their Critical Care usage rates (Intensive Care and/or High Dependency Units) with other hospitals in their AIHW peer group.
- Principal Referral critical care unit benchmarking report (PDF 257KB)
- Acute Group A critical care unit benchmarking report (PDF 336KB)
- Acute Group B critical care unit benchmarking report (PDF 323KB)
- Acute Group C and Women's critical care unit benchmarking report (PDF 339KB)
Antifungal benchmarking reports by state/territory
Jul 2025 to Dec 2025
These six-monthly reports allow contributors to compare their antifungal usage rates with other hospitals within their state or territory. Usage rates of antifungals are highly dependent on the casemix (e.g. haematology/oncology or transplant services) and acuity of the hospital.
- New South Wales and ACT antifungal benchmarking report (PDF 335KB)
- Queensland and Northern Territory antifungal benchmarking report (PDF 234KB)
- South Australia antifungal benchmarking report (PDF 296KB)
- Victoria antifungal benchmarking report (PDF 309KB)
- Western Australia antifungal benchmarking report (PDF 230KB)
- Tasmania antifungal benchmarking report (PDF 224KB)
Contributor reports from the NAUSP portal
Hospitals contributing to NAUSP can download reports directly from the NAUSP portal showing longitudinal usage rates for their individual hospitals. These contain charts comparing the individual hospital’s usage compared to the average usage at similarly peered hospitals. Hospitals that contribute usage data for particular specialties/locations can access usage reports for critical care, haematology/oncology, respiratory and obstetrics/gynaecology.
Disclaimer
Usage rates reported in previously published NAUSP reports may differ from current reports. The Defined Daily Dose (DDD) values for some commonly used antimicrobials were changed by the WHO in January 2019. Due to these changes, usage rates in more recently published reports may not be directly comparable with prior reports that utilised the former DDD values for the analysis. In addition to amendments to WHO DDDs, rates may differ as a result of retrospective data adjustments or varying numbers of hospitals contributing to aggregated data.
