Date published: 1 February 2022

The Australian Refined Diagnosis Related Groups (AR-DRGs) is a classification that provides a clinically meaningful way to relate or group the number and type of patients treated in admitted acute episodes of care to the resources required in treatment. AR-DRGs group patients with similar diagnoses requiring similar hospital services.
