[A critical DRG-evaluation of cases with inflammatory bowel disease]. / Ein kritischer DRG-Blick auf Fälle mit chronisch entzündlichen Darmerkrankungen.

INTRODUCTION: Whether inpatients with inflammatory bowel disease (IBD) are reimbursed in a cost-covering manner in German hospitals has not yet been investigated. In this context, the present study analyses the reimbursement situation (cost-revenue comparison) of IBD in German hospitals with regard to the complexity of the disease and the type of care. METHODS: For this retrospective study, anonymized case data, including cost data from the InEK calculation (§ 21-4 KHEntgG) of the DRG project of the German Society for Gastroenterology, Digestive and Metabolic Diseases (DGVS) from 2019, were available. 3385 cases with IBD the as main diagnosis from 49 hospitals were analyzed. To investigate the impact of disease complexity on reimbursement, different variables were analyzed, including gastroenterological complications, infections, the reason for admission, and additional charges. To investigate possible center effects, hospitals were grouped by type of care, mostly defined by the number of beds. RESULTS: The present study shows that all types of care can be classified as not cost-covering on average. The under-recovery is, on average, 10% (296 € absolute under-recovery) and varies between the types of care. Cases with higher complexity show a higher cost under-recovery than cases with lower complexity. At the DRG level, the analyzed costs of the three most common IBD DRGs for inlier patients are higher than the InEK costs; however, the difference is not significant. Nonetheless, cases with the admission reason transfer of specific DRGs bear significantly higher costs. DISCUSSION: Our results show that CED is not reimbursed in a cost-covering manner. This is due to inadequate reimbursement for gastroenterological complications, infections, specific procedures, and emergency and transfer cases. Transfer cases bear significantly higher costs.

[Prognostic significance and economic burden of hepatic encephalopathy in liver cirrhosis in German hospitals based on G-DRG data]. / Mortalität und ökonomische Auswirkungen der hepatischen Enzephalopathie bei Leberzirrhose in deutschen Krankenhäusern auf der Basis von G-DRG-Kostendaten.

INTRODUCTION: Hepatic encephalopathy (HE) represents a frequent complication of liver cirrhosis with negative effects on patients' lives. The prevalence of clinical HE is estimated to be between 30-45 %. Regardless of its clinical and prognostic relevance HE is considered to be underdiagnosed. METHODS: Beyond a systematic analysis of mortality of HE, we investigated the economic impact and reimbursement situation for HE in patients with liver cirrhosis in Germany. For the retrospective analysis, anonymized data (2011-2015) concerning expenses and diagnoses (§â€Š21-4 KHEntgG) were obtained from 74 participating hospitals of the Diagnosis Related Groups (DRG) Project of the German Gastroenterological Association (DGVS). Furthermore, results were compared with case data from all German hospitals provided by the German Federal Authority on Statistics (Statistische Bundesamt (Destatis), Wiesbaden). RESULTS: In participating hospitals 59 093 cases with liver cirrhosis were identified of which 14.6 % were coded as having HE. Hospital mortality was threefold increased compared to cirrhosis-patients without HE (20.9 versus 7.5 %). Cases with cirrhosis as well as the proportion with HE increased over time. Compared to all patients with cirrhosis, reimbursement for HE patients produced a deficit (of up to 634 € for HE grade 4). DISCUSSION: Mortality is threefold increased in patients with cirrhosis when an additional HE is diagnosed. Hospitals participating in the DGVS-DRG-project coded 2 % more HE cases among their cirrhosis cases than the rest of hospitals either because of a selection bias for greater disease severity or because of better coding quality. At present, reimbursement for HE patients on the basis of F-DRG-system produced a deficit.
