In-scope costs ÷ Total NWAU

In-scope costs are a subset of the total costs for acute admitted patients. Costs are included if they are comparable or if they cannot be separated from other costs.  Costs are considered comparable if there is consistency of cost information provided by each of the states and territories. 
 

In-scope costs include the direct and overhead costs associated with the following cost buckets:

• Allied health

• Critical care

• Hotel goods and services

• Imaging

• Non clinical

• On-costs

• Pharmacy

• Pathology

• Prostheses

• Special procedures suites

• Ward supplies

• Ward medical

• Ward nursing

Note: costs for non-qualified new born(s) are allocated to mothers

Indicator: National Health Performance Authority, Hospital Performance: Total National Weighted Activity Unit, 2016

Total National Weighted Activity Units (NWAU), developed by the Independent Hospital Pricing Authority (IHPA), measures total hospital activity using a common unit of activity, termed NWAU.

For the specification of this indicator see;

Hospital

Peer Group

Cost per NWAU, developed by the Independent Hospital Pricing Authority (IHPA), measures the costs incurred against a common unit of activity termed NWAU. The NWAU is the unit for counting activity used in the nationally consistent Activity Based Funding system introduced under the National Health Reform Agreement 2011 (NHRA).

The 'average' hospital service is funded by one NWAU. More intensive and expensive activities are funded by multiples of NWAUs, and simpler and less expensive activities are funded by fractions of an NWAU.

This indicator compares the Cost per NWAU for acute admitted patients and does not include ED costs associated with each patient’s admission. The Cost per NWAU measure includes patients whose services were eligible for Activity Based Funding from the Commonwealth.
