Abstract

Since the introduction of the G-DRG-system in Germany for the reimbursement of in-hospital patients in 2003 the Institute for the Hospital Remuneration System (InEK) annually determines case reimbursements for currently 1300 individual diagnosis-related groups (DRGs). These are based on the cost documentation of 200 representative hospitals, coopted by InEK ( 21-KHEntG-dataset). Since DRGs represent cost averages, one half of German hospitals would be expected to report an annual income surplus, the other half a deficit. In spite of sustained cost reductions two thirds of public University Hospitals, but only 29 % of non-University hospitals, report annual deficits. The German Society for Gastroenterology, Digestive and Metabolic Diseases (DGVS) has obtained the 21-cost-dataset from 74 InEK-hospitals and 7 Mio anonymized cases since 2012 in order to appeal for individual DRG-corrections to InEK. In the current project this database was used to investigate whether the cost of care at University Hospitals is appropriately reflected in three representative DRGs and OPS codes (operation and procedure codes): Liver cirrhosis with hepatic encephalopathy, endoscopic procedure-tiers, and an endoscopic intervention after patient transfer from one hospital to another. The analysis reveals that the higher patient complexity, severity and cost at University Hospitals cannot be corrected by modification or further differentiation of individual DRGs within the existing G-DRG-system. Even in DRGs for which a differentiation would be possible and economically appropriate it is often not permitted. A further rise of the systematic deficit of German University Hospitals (currently 300 Mio. Euro annually) can only be prevented by introducing either a case-based DRG-System-Surcharge for University Hospitals or by separation of a University Hospital U-DRG-System from the general G-DRG-System.
