Shaping the System - The DRG Evaluation Project of the German Society for Gynaecology and Obstetrics (Deutsche Gesellschaft für Gynäkologie und Geburtshilfe, DGGG).

The German DRG system is annually adapted to the changing services provided. For the further development, the self-governing body and its DRG Institute (InEK) depend on participation of the users. For one of the DRG evaluation projects initiated by DGGG, cost and performance data for the year 2011 from 16 hospitals were available.

Development of lengths of stay and DRG cost weights in dermatology from 2003 to 2006.

Background: The G-DRG per case payments are calculated annually on the basis of present output and cost data provided from German hospitals. The economic valuation of dermatology-related DRGs depends largely on inpatients' length of stay. At present, longitudinal analyses of dermatologic hospital data considering the development of length of stay under DRG conditions are not available.
