[Impact Analysis of a new, Cross-sector Service Provision of Gastroenterologic Endoscopic Services in Accordance with 115f SGB V (Hybrid-DRG): Allocation Matrix and Cost Analysis].

Background: With the introduction of §115f SGB V, the prerequisites for "sector-equal remuneration" ('Hybrid DRG') have been created. In an impact analysis, we assigned inpatient gastroenterological endoscopic (GAEN) cases in a matrix of future hybrid DRG versus outpatient surgery (AOP) or inpatient treatment.

Methods: In selected DRGs (G47B, G67A, G67B, G67C, G71Z, H41D, H41E) an allocation matrix of GAEN cases was created on medical grounds.

[A critical DRG-evaluation of cases with inflammatory bowel disease].

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.

[Costs of potentially outpatient endoscopic procedures in cases with a 1-day hospital stay versus a longer stay].

Introduction: The transfer of patient care and medical interventions that was previously provided on an inpatient basis to outpatient settings is a stated goal of health politics. It is unclear to what extent costs of an endoscopic procedure and the disease severity depend on the duration of inpatient treatment. We therefore examined whether endoscopic services for cases with a one-day length of stay (VWD) are comparably expensive to cases with a longer VWD.

[Limits of the G-DRG system to reflect Complexity in German University Hospitals].

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.
