The results are reported of a first round of costing by DRG in seven major teaching hospital sites in Sydney using the Yale cost model. These results, when compared between the hospitals and with values of relative costs by DRG from the United States, indicate that the cost modelling procedure has produced credible and potentially useful estimates of(More)

Introduction A principal reason for investing in case mix as a tool for hospital administration is that it allows the value of production embodied in an episode of care to be different from the cost of that episode. Useful case-mix evaluation retains a statistical nexus between value and cost of production. The value placed on a hospital system’s output(More)
Introduction The thinking behind DRGs contains not only clinical concepts but also ideas drawn from health economics and statistics (particularly sampling theory). One example of the influence of economics is the literature on DRGs in reimbursement systems. DRGs are generally placed between fee for service and risk -adjusted capitation. An example of the(More)
Introduction Australia is currently undergoing a change in the Casemix payment environment. This is the result of an agreement to move to a more nationally-consistent approach to activity-based funding (ABF) for services provided in public hospitals. ABF for acute inpatients will be based on the Australian Refined DRG Casemix system, which is derived from(More)
This paper reports the results of an evaluation study of the Australian National Diagnosis Related Groups (AN-DRGs). The evaluation was based on statistical rather than clinical criteria with the principal goal being to provide information for the future development of the classification system. As well as comparing versions 1.0 to 3.0 of AN-DRGs, the(More)
The Diagnosis Related Group (DRG) system is now used extensively in Australia to classify acute inpatients for many applications, including payments to hospitals. The quality of the inpatient separation data affects the performance of the DRG version, especially its predictive validity. Data from the State of Maryland, in the United States, contain more(More)
