Australian Refined Diagnosis Related Groups (AR-DRGs)
The Australian Refined Diagnosis Related Groups (AR-DRGs) is a classification system, which provides a clinically meaningful way to relate the number and type of patients treated in a hospital to the resources required by the hospital. AR-DRGs group patients with similar diagnoses requiring similar hospital services.
Episodes of admitted acute care are assigned with disease and intervention codes by health information managers or clinical coders. AR-DRGs are then assigned based on these codes and a number of other routinely collected variables including: age, sex, mode of separation, length of stay, newborn admission weight and hours of mechanical ventilation.
This process of assigning patient episodes to an AR-DRG is complex and is carried out using software that contains the AR-DRG algorithms, referred to as a 'grouper'.
AR-DRGs are used to calculate public hospital funding on an activity basis. They are also used for
- performance management
- facilitation of payment of services in the private healthcare sector
- research into the quality of healthcare and patient safety
- health service planning.
