Implementation of an internal transfer pricing system for anaesthesia services

Internal transfer pricing system (ITPS) of anaesthesia services is established to guarantee a close connection of delivered service and the budget of the department of anaesthesia. In most cases a time-based system is used with the pricing unit being calculated as the quotient from the enumerator "costs" divided by the denominator "anaesthesia time in minutes" The implementation of a transfer pricing system requires the identification of all relevant costs caused by the department of anaesthesia and a cost centre structure is needed which allocates all costs correctly according to their cause. The regulations regarding cost calculations as defined by the German DRG System should be considered. To generate valid data not only the necessary technical infrastructure is needed, but also detailed training of the staff and plausibility checks are needed to ensure correct and complete data. Subsequent agreements with the hospital administration are necessary in order to adjust the system if extrinsic cost increases occur. This paper gives a step-by-step guidance for the successful implementation of an internal transfer pricing system based on anaesthesia time.
