BACKGROUND AND OBJECTIVE: With the advent of the DRG system, German hospitals are being forced to improve cost transparency and to uncover inefficient structures. METHODS: Diagnosis-based costs were calculated in the Department of Dermatology in the University Hospital of Freiburg for ten samples, each containing 20 cases. By using in-patient files, cost and productivity information for the fiscal year 2000 was attributed to each single case in a bottom-up-approach. The resulting total costs per case were contrasted to their remuneration under the DRG system. RESULTS: Average case costs were determined between EUR 1,339.83 and EUR 5,714.73. With 19.3% to 28.4% of total costs, nursing costs were the biggest single cost factor. Prolonging the length of stay incurred average extra costs of EUR 144.26 to EUR 199.98 per case and day. The correlation of case costs and their corresponding DRG cost weights was modest with r=0,48. There was considerable cost variance within individual DRGs. CONCLUSIONS: The diagnosis-related cost calculation reveals striking cost differences relating to specific diagnoses. This method is more suitable for cost calculations in the hospital than more general approaches.
