Collection and Usage Attributes
Hospital Based Corporate Information System (HBCIS):
MDCs are calculated at the facility using the "derived from" related data items. Transmit as fixed width 3 character, left adjusted, blank if null.

Queensland Hospital Admitted Patient Data Collection (QHAPDC):
As part of QHAPDC processing of inpatient data by the Data Services Unit (DSU), MDCs are re-calculated using the "derived from" related data items and any discrepancies with facility calculated items are queried with the facility.
The development of the Australian Refined Diagnosis Related Group (AR-DRG) classification has created a descriptive framework for studying hospitalisation. DRGs provide a summary of the varied reasons for hospitalisation and the complexity of cases a hospital treats. Moreover, as a framework for describing the products of a hospital (that is, patients receiving services), they allow meaningful comparisons of hospitals' efficiency and effectiveness under alternative systems of health care provision.
The AR-DRGs are a patient classification scheme consisting of classes of patients who are similar clinically and in terms of their consumption of hospital resources. AR-DRG version 5.0 was released by the Department of Health and Ageing in September 2002 for use with ICD-10-AM 3rd edition codes from July 2002.
