Identifying and definitional attributes
|Metadata item type:||Indicator|
|Short name:||Weighted separations (care type 1)|
|Registration status:||Tasmanian Health, Archived 09/12/2016|
This indicator measures the total weighted separations which indicate the costliness of an Australian Refined Diagnosis Related Group (AR-DRG) relative to all other AR-DRGs such that the average cost weight for all separations in 1.00.
A separation for an AR-DRG with a cost weight of 5.0, therefore, on average costs 10 times as much as separations with a cost weight of 0.5.

Collection and usage attributes
Calculated using the total number of weighted separations for Acute Inpatient Activity (Care Type 1) including Outside Referred Patients and acute mental health inpatient activity.
The average cost weight used to construct this indicator is calculated from the National Hospital Morbidity Database, using AR-DRG public cost weights published by the Department of Health and Ageing.
Casemix adjustment is based on the round of cost weights attributed to the AR-DRG assigned to each separation.
National Hospital Cost Data Collection (NHCDC) Round 16 (2011-12) AR-DRG v6.0x public sector estimated cost weights and AR-DRG v6.0x will be applied to calculate weighted separations for 2014-15.
For 2012-13 onwards, this indicator excludes admissions funded by the Tasmanian Government Endoscopy and Elective Surgery Initiative and the National Partnership Agreement on Improving Health Services in Tasmania.
The formula to calculate weighted separation is:
