Additional Information
To enable greater consistency between HCP and PHDB Annual Report statistics and figures published in the Australian Institute of Health and Welfare’s (AIHW) Australian Hospital Statistics annual reports, the hospital type (i.e. public or private) has been adjusted in a small number of cases. Further information is available in each Annual Report’s Explanatory notes section.
Although improvements have been made, the Department notes there is an ongoing issue in the HCP (hospital to insurer), HCP1 (insurer to Department) and PHDB data involving the supply of non-admitted service data such as those involving patients receiving services as outpatients or visited by community nurses at home. These relate to the AR-DRGs (version 9.0): U60Z (Mental Health Treatment W/O ECT, Sameday) and V62B (Alcohol Use and Dependence, Minor Complexity).
As outlined in the relevant data specifications, HCP, HCP1 and PHDB data should only contain admitted patient care episodes. A relatively small number of these additional non-admitted records are currently included in both the HCP and PHDB Annual Reports as there is insufficient information available to enable the Department to exclude them. The Department continues to consult with hospitals, health insurers and software vendors to ensure future data submissions are consistent with the scope of each data collection and contain admitted episodes only.
The Department also notes the under-reporting of dialysis related separations in HCP1 and PHDB which primarily impacts AR-DRGs (version 9.0): L61Z (Haemodialysis) and L67C (Other Kidney and Urinary Tract Disorders, Minor Complexity) and the over-reporting of rehabilitation separations in HCP1 which primarily impacts AR-DRG (version 9.0): Z60B Rehabilitation, Minor Complexity.
