Purpose:
To allow physicians to be more selective in their request for a radiograph of the wrist and to potentially reduce costs, the Amsterdam Wrist Rules (AWR) have been developed, externally validated, and recently also implemented. The aim of this study was to conduct an incremental cost analysis and budget impact analysis of the implementation of the AWR at the emergency department (ED) in the Netherlands.
Methods:
A cost-minimisation analysis to determine the expected cost savings for implementation of the Amsterdam Wrist Rules. The incremental difference in costs before and after implementation of the AWR was based on the reduction in costs for radiographs, the cost savings due to reduction of ED consultation times and the costs of a re-evaluation appointment by a physician.
Results:
In the Netherlands, implementation of the AWR could potentially result in 6% cost savings per patient with a wrist injury. In addition, implementation of the AWR resulted in €203,510 cost savings annually nationwide. In the sensitivity analysis, an increase in physician compliance to 100% substantially increased the potential total amount of annual cost savings to €610,248, which is 6% of total costs before implementation. Variation in time spent at the ED, a decrease and increase in costs and patients presenting annually at the ED did not change the cost savings substantially.
Conclusion:
Implementation of the AWR has been shown to reduce direct and indirect costs and can, therefore, result in considerable savings of healthcare consumption and expenditure.
