DRGs as management information or reimbursement method
1Westmead Hospital, NSW.
Insights
Diagnosis Related Groups (DRGs) should not fund hospitals due to incentives for misclassification. As a management tool, DRGs can link hospital casemix to costs and outcomes, improving efficiency.
Area of Science:
- Health Services Management
- Hospital Administration
- Healthcare Economics
Background:
- Diagnosis Related Groups (DRGs) offer dual potential as management information systems or hospital funding mechanisms.
- Current Australian hospital systems face significant social and technical efficiency challenges.
- Casemix funding models primarily address technical efficiency, potentially overlooking broader systemic issues.
Purpose of the Study:
- To evaluate the suitability of Diagnosis Related Groups (DRGs) as both a hospital funding method and a management information system.
- To identify the optimal application of DRGs within the Australian healthcare context.
- To explore the need for a common language linking hospital casemix, costs, and patient outcomes.
Main Methods:
- The study presents a critical analysis of the dual-use potential of DRGs.
- It examines the inherent conflicts and incentives associated with using DRGs for hospital reimbursement.
- The argument is supported by considering the broader social and technical efficiency issues in hospital management.
Main Results:
- DRGs create incentives for misclassification and "game playing" when used for hospital reimbursement.
- Using DRGs solely for funding can undermine their effectiveness as a management tool.
- A common language connecting casemix, cost, and outcome is essential for improving efficiency.
Conclusions:
- DRGs are not suitable for dual use as both a hospital funding mechanism and a management information system.
- To enhance hospital efficiency, DRGs should be utilized strictly as a management information system, not for reimbursement.
- Effective implementation requires separating the funding and management information functions of DRGs to foster a common language for cost and outcome analysis.
Abstract:
Diagnosis Related Groups (DRGs) can be used either as a system of management information or as a method of funding hospitals. They cannot be used as both, for the incentives which are generated if hospitals are reimbursed by DRG encourage misclassification and game playing. It is argued that the major problem facing the Australian hospital system is social, not technical, efficiency. Funding by casemix focuses on the latter. If efficiency of either sort is to be improved, managers and clinicians need a common language which links casemix to cost and outcome. Used as a management information system, DRGs meet this need, but to do so effectively they should not be burdened with the additional responsibility of hospital reimbursement.
