Underfunding of German university-based high-performance medicine exemplified by the treatment of varices in cirrhosis.

ABSTRACT

Facing increasing economization in the health care sector, clinicians have to adapt not only to the ever-growing economic challenges, but also to a patient-oriented health care. Treatment costs are the most important variable for optimizing success when facing scarce human resources, increasing material- and infrastructure costs in general, as well as low revenue flexibility due to flat rates per case in Germany, the so-called Diagnosis-Related Groups (DRG). University hospitals treat many patients with particularly serious illnesses. Therefore, their share of complex and expensive treatments, such as liver cirrhosis, is significantly higher. The resulting costs are not adequately reflected in the DRG flat rate per case, which is based on an average calculation across all hospitals, which increases this economic pressure. Thus, the aim of this manuscript is to review cost and revenue structures of the management of varices in patients with cirrhosis at a university center with a focus on hepatology. For this monocentric study, the data of 851 patients, treated at the Gastroenterology Department of a University Hospital between 2016 and 2020, were evaluated retrospectively and anonymously. Medical services (e.g., endoscopy, radiology, laboratory diagnostics) were analyzed within the framework of activity-based-costing. As part of the cost unit accounting, the individual steps of the treatment pathways of the 851 patients were monetarily evaluated with corresponding applicable service catalogs and compared with the revenue shares of the cost center and cost element matrix of the German (G-) DRG system. This study examines whether university-based high-performance medicine is efficient and cost-covering within the framework of the G-DRG system. We demonstrate a dramatic underfunding of the management of varicose veins in cirrhosis in our university center. It is therefore generally questionable whether and to what extent an adequate care for this patient collective is reflected in the G-DRG system.
