National Benchmarking Portal
The National Benchmarking Portal (NBP) is a secure web-based application that provides access to data collected by IHACPA.
By providing open access to data with appropriate privacy protections, the portal supports informed policy decisions and helps improve patient outcomes. IHACPA has made the NBP publicly available so clinicians, hospital managers, researchers and the general public can explore and use these insights.
Areas of focus
The NBP includes insights from data collected between 2017–18 and 2022–23, grouped into 3 areas of focus:
- cost per national weighted activity unit (NWAU)
- hospital acquired complications (HACs)
- avoidable hospital readmissions (AHRs)
Each area has its own dashboard. You can explore a cost per NWAU overview dashboard, then explore more detailed information through the cost detail and NWAU detail dashboards. The HAC and AHR areas include dashboards that show trends, activity detail and NWAU adjustment detail.
In every dashboard, you can filter data by selecting your state and territory, local hospital network, hospital or AIHW hospital peer group. You can also apply additional filters specific to each dashboard to refine your view.
Data aggregation
The NBP aggregates data using common variables, including hospitals or establishments, classification end-class, care stream and quarter of separation. When you apply filters that result in a sufficiently small sample size (30 records for the cost per NWAU and 20 records for HAC and AHR areas of focus), the system automatically masks indicators and charts. This protects patient confidentiality and ensures statistical robustness.
