Clinical representation in the development of casemix: measures and applications in Australia.

The Australian Casemix Clinical Committee coordinated the clinical evaluation of inpatient casemix classifications leading to the development of Australian national diagnosis-related groups 1, 2 and 3. It has provided and will continue to provide advice on clinical matters associated with casemix activities to the Commonwealth and State health authorities, public and private hospital associations, insurers and the clinical professions. In future, all clinicians will be expected to understand casemix, diagnosis-related groups and cost weights, especially those relevant to their speciality.
