[The economic challenges of polytrauma care].

Following the introduction of DRGs ("diagnosis-related groups") in Germany, reimbursements changed from a per diem rate to a flat charge per patient. DRGs are defined by the German Institute for the Hospital Remuneration System (InEK, Institut für das Entgeltsystem im Krankenhaus) along with the respective reimbursement. The revenues are set according to the diagnoses and procedures. In complex cases like serious injury this applies for the average diagnoses and procedures. As a result, several groups reported costs of polytrauma care as high as 70,000 euro with losses as high as 20,000 euro. In the USA, a similar constellation has lead to the closure of trauma centers. The main reasons for the financial deficit are heterogeneity of polytrauma patients and contingency costs. Both are difficult to transfer to a case-based compensation system. Since the German DRG system was designed to learn during introduction, there were adjustments to reimbursements for polytrauma care in the initial phase. However, in recent years, no further improvements in the care of severely injured patients have been seen. The deficit per seriously injured patient currently runs at approx. 5000 euro. A renewed joint effort is required in order to avoid an economy-related reduction in quality of care.
