Abstract
BACKGROUND AND OBJECTIVES: Estimated treatment costs of severely injured patients were often added to registry-based analyses. In the past, the TraumaRegister DGU® used a modular cost estimator for this purpose. A recent research project initiated by the German Trauma Society (DGU) evaluated the reimbursement of severely injured patients in the German DRG system. This project also allowed the generation of an improved update of the registry's cost estimator. METHODS: Detailed cost data for the acute therapy of severely injured patients were available from 10 hospitals that also participate in the TraumaRegister DGU®. Cost and registry data were matched using hospital code, date of admission, age, sex, and length of stay. A multivariate regression analysis with hospital costs as dependent variable included patients with an injury severity score (ISS) ≥ 9 points who stayed in hospital at least three days. All injuries were coded using the abbreviated injury scale (AIS). A total of 1002 patients treated in 2007 and 2008 were successfully matched. Cost data was collected for each case according to the method of calculation provided by the German DRG Institute (InEK). RESULTS: The mean age was 44 years and 73 % were males; the mean ISS was 27 points. The following aspects were significantly associated with the overall hospital costs: length of stay on the intensive care unit (ICU) (1152 € per day); length on intubation/ventilation (568 € per day); length of stay on normal ward (531 € per day); number of blood products (packed red blood cells; fresh frozen plasma) transfused until ICU admission (258 € per unit); a serious abdominal injury (AIS ≥3; 2849 €); an instable pelvic fracture with relevant blood loss (AIS 5; 7505 €); and a serious injury of the extremities (AIS 3-4; 2418 €). The estimated overall treatment costs calculated by the above mentioned formula averaged 22,138 € per case. The deviation from the measured real costs (21,546 € per case) was less than 3 %. CONCLUSION: Using only key data available for all patients in the registry, a valid cost estimator for acute care costs is now available in the TraumaRegister DGU®.
