Collection and usage attributes

Computation description:

Total separations excludes newborns without qualified days, and records that do not relate to admitted patients (hospital boarders and posthumous organ procurement).

Average cost weight is calculated from the National Hospital Morbidity Database, using the 2007-08 Australian Refined Diagnosis Related Group (AR-DRG) version 5.1 cost weights published by the Department of Health and Ageing.

Casemix adjustment is based on Diagnosis Related Group (DRG) assigned to each separation.

For more detailed information regarding the methodology, please refer to Australian hospital statistics 2007–08, Appendix 1.

Computation:Numerator ÷ Denominator
Numerator:

Total reported recurrent expenditure (excluding depreciation) multiplied by the admitted patient cost proportion** reported for each hospital

** The estimated proportion of total hospital expenditure that relates to admitted patient care.

Further data development / collection required:Specification is likely to be interim.

This work will be progressed by the relevant NP Implementation Group, convened by the Department of Health and Ageing (DoHA). Only three jurisdictions have an estimate of costs for acute and total admitted patient activity, and this proportion is for public hospitals. This PI will require development of additional expenditure collections as well as development of uniform indicators using that collection.

Other issues caveats:

Data limited to public hospitals in 2007–08.
