In Germany a new casemix-related reimbursement system with "diagnosis related groups" (DRGs) for inpatient treatment was started in 2003. The first German system G-DRG 1.0 was developed on the basis of the Australian AR-DRG version 4.1. German inpatient treatment in radiation oncology was not specifically represented in this system due to the very different health care systems. As the DRG system was planned as a pricing system with severe effects on the funding of radiation oncology departments, an adjustment was urgently needed. For the modification, national data about pattern of care and economic relevance were needed. ⋯ This evaluation revealed the deficits in the G-DRG system 1.0 (and the AR-DRG system 4.1) related to the inpatient treatment in radiation oncology departments. Modifications could be proposed for following years. In 2004-2006, the regulatory boards adopted several implications of these data for the improvement of the German casemix-based hospital-financing system.

The aim of this study was to improve the irradiation technique for the treatment of head-and-neck tumors and, in particular, to make use of the advantages found in modern 3D planning to protect the parotid glands. ⋯ The combination of static coplanar and arc field technique (T3) resulted in a substantially better protection as compared to both other techniques. This was especially the case with regard to the contralateral parotid gland, when the dose distributions were calculated equally for PTV and boost volume. In this study, the D(mean) dose of the contralateral parotid gland was lower than the TD(50) of 37 Gy (95% confidence interval 32-43 Gy) previously assumed by the authors. Therefore, it can be concluded that in the present study a more intensive protection of this gland and a reduction in xerostomia were possibly obtained.
