[Quality assessment of dermatology in the G-DRG system 2004].

Background: Since January 2004, all German hospitals have been obliged to operate with a new hospital funding system based on DRGs. For the DRG system to serve as a fair basis for reimbursement requires that the dermatologic services be adequately covered in the classification system. The German Dermatologic Society (DDG) in cooperation with the DRG-Research Group of the University Hospital Muenster carried out a DRG evaluation study. Based on these results, suggestions for the adjustment of the G-DRG system were proposed by the DDG in the G-DRG adaptation round for 2004.
Methods: Based on data of the DRG evaluation project (14,555 dermatological cases from 19 hospitals) the homogeneity in the G-DRG system 2004 was examined and compared with the quality of depiction in the G-DRG version 1.0.
Results: The correlation between expenditure and case mix index in the hospitals improved in the G-DRG system 2004. Most proposals submitted by the German Dermatologic Society for the adaptation into the G-DRG system 2004 were accepted. Some fundamental problems such as reimbursement of high cost drugs and special services, as well as the reimbursement of high and low outliers, were only marginally addressed.
Conclusions: The G-DRG system 2004 will need to be continuously adapted in the field of dermatology. Based on this work, the German Dermatologic Society has made suggestions to be adapted in the G-DRG system 2005 and submitted them to the German DRG Institute.
