Patient costing was conducted in accordance with 2006-07 NSW PPDC Standards AR-DRG version 5.
The median length of stay (LOS) was three days (range 1-126), while the median AR-DRG allocated LOS was 3.
For the AR-DRGs allocated to the 206 trauma patients, the average in-hospital AR-DRG reimbursement was $12,751 (range: $1,370-$147,988), while the average actual cost was $15,104 (range: $782-$195,022).
Of the 43 AR-DRG groupings identified in this group of patients, there were 27 (62.
However, findings from this pilot study are supported by the international literature, which has consistently demonstrated that the AR-DRG method of describing the complex trauma patient's injuries is insufficient and underestimates the true cost of the patient's treatment requirements (Aucar & Hicks 2005, Grotz et al.
In the current study, the average AR-DRG cost increased as injury severity increased.
Assault-related penetrating trauma, burns, injuries to pedal- and motor-cyclists and motor vehicle occupants were all under-funded in the current study, they also had the largest variance in AR-DRG LOS.
For some health conditions, such as those encountered in rehabilitation or palliative care, AR-DRGs have not been found to be good indicators of the 'true' types of patient episodes (Eager & Harvey 2001).
For this reason the determination of appropriate AR-DRGs derived from the clinical coding process can be difficult (Curtis, Bollard & Dickson 2002).
1) AR-DRG is a patient classification scheme based on ICD-10-AM/ACHI/ACS codes.
The grouping logic for an AN-SNAP class is not available in the same way as purchasing the AR-DRG grouper software, therefore this posed a significant problem for AHSA including a knowledge gap as to the intricate details of the AN-SNAP class grouping logic.
This ensured that all AN-SNAP classes could be verified by AHSA in similar manner that all AR-DRGs in the episode file are regrouped in all relevant versions of the grouping logic.
