IntroductionSeverely injured patients represent a relevant financial cost factor in the health system especially for high level trauma centres. The introduction of a"diagnosis-related group" (DRG) system in Germany further revealed the potential negative economic impact of severely injured patients for trauma centres. In recent years several changes of the specific DRG for severely injured patients occurred with the aim of a convenient reimbursement for the trauma patient.Material And MethodsThe present study analysed 38 multiply injured patients admitted in the first half of the year 2004. These patients were analysed in terms of the respective DRG that was attributed to the patient on the basis of the definition criteria for 2004 and 2005. In addition for the same patient group the total inpatient treatment costs were calculated according to the algorithm developed by the Working Group on Polytrauma of the German Trauma Society.ResultsThe analysis revealed three major problems in the reimbursement for severely injured patients according to the German DRG system: (1) In spite of the additional payment for blood compounds on top of the DRG reimbursement in 2005 a mean economic deficit of more than 4000 euro remains for each severely injured patient. (2) In 30% of the analysed trauma patients the combination of the diagnosis and operations did not lead to a specific polytrauma DRG or to an intensive care medicine DRG. (3) In the patients that could not be attributed to a polytrauma DRG, the economic deficit was with an average of more than 9000 euro even higher. This attribution aspect is also currently relevant, since the definition criteria for a polytrauma DRG were not changed in 2006 or 2007.ConclusionWe conclude that besides the recent changes in the reimbursement for polytrauma DRGs, which have been at least partly adapted to the real financial burden of these patients, the definition of a severely injured patient in the German DRG system may also need to be revised.
