[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]. / Auswirkungsanalyse einer neuen, sektorenübergreifenden Erbringung bisher stationärer endoskopischer gastroenterologischer Leistungen entsprechend §115f SGB V (Hybrid-DRG): Zuordnungsmatrix und Kostenanalyse.

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. For this purpose, service groups from the DGVS service catalog ('Leistungskatalog') were assigned to the groups: 'Hybrid-DRG', 'AOP' and 'Inpatient' by a group of experts based on the DGVS position paper. Cost data from the DGVS-DRG project for the 2022 data year from 36 InEK calculation hospitals with a total of 232,476 GAEN cases were evaluated. RESULTS: 26 service groups from the DGVS service catalog were assigned to a "Hybrid-DRG", 24 to the "inpatient" group, and 12 to the "AOP" group. 7 performance groups were splitted "depending on the OPS code" and classified at this level. Cases with additional fees were excluded from a hybrid DRG because these cannot be agreed there.The cost analysis shows that services that are already in the AOP have a similar cost level to services that have been classified as 'Hybrid-DRG'. With the cost calculation, a cost level could be presented for the hybrid DRGs formed. CONCLUSION: Based on clearly defined structural, procedural and personnel requirements, services from suitable DRGs can be transferred to a hybrid DRG. Assigning services without the involvement of clinical experts seems extremely difficult. Case assignment based on arbitrary contextual factors increases complexity without demonstrably increasing the quality of the assignment and needs to be further developed. A cost analysis can be derived from the known inpatient costs and must serve as the basis for the 2025 Hybrid DRG catalog.

[Outpatient care in pulmonology - a scientific analysis and a position paper of the German Society of Respiratory Medicine (DGP)]. / Ambulantisierung in der Pneumologie ­ eine wissenschaftliche Analyse und ein Positionspapier der DGP.

INTRODUCTION: The ambulantization of patient care that were previously provided as inpatient service is one of the goals of the current reform in the German healthcare system. In pulmonology, this particularly applies to endoscopic procedures. However, the real costs of endoscopic services, which form the basis for the calculation of a future so called hybrid DRG or in the AOP catalog, are unclear. METHODS: After selection of use cases including endoscopic procedures which can be performed on an outpatient basis by a committee of experts the appropriate DRGs were identified from the §â€Š21-KHEntgG data for 2022 published by the Institute for the Hospital Remuneration System (InEK). The costs were calculated from the respective InEK cost matrix added by the calculated material costs. RESULTS: The use cases suitable for outpatient treatment were systematic endobronchial ultrasound (EBUS) with transbronchial needle aspiration (calculated costs €â€Š2,175.60 without or €â€Š3,315.60 including PET/CT), navigation-assisted bronchoscopy for peripheral lesions (depending on the methodology €â€Š2,870.23 to €4,120.23) and diagnostic (flexible) bronchoscopy (€â€Š1,121.02). CONCLUSION: Outpatient treatment of endoscopic procedures that were previously performed inpatient is possible and necessary, and the costs calculated in this publication can form a reliable basis for appropriate reimbursement. Together with a structural quality that has been transformed to outpatient service and cross-sector cooperation, continued high-quality care for pneumological patients can be ensured.

[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.

[Costs of potentially outpatient endoscopic procedures in cases with a 1-day hospital stay versus a longer stay]. / Kosten potenziell ambulant erbringbarer endoskopischer Leistungen in Fällen mit 1-Tages-Verweildauer gegenüber einer längeren Verweildauer.

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. METHODS: Outpatient services were selected from the DGVS service catalog. Day cases with exactly one such gastroenterological endoscopic (GAEN) service were compared with cases with VWD>1 day regarding their patient clinical complexity levels (PCCL) and mean costs. Data from the DGVS-DRG project with §21-KHEntgG cost data from a total of 57 hospitals from 2018 and 2019 served as the basis. Endoscopic costs were taken from cost center group 8 of the InEK cost matrix and plausibility checked. RESULTS: A total of 122,514 cases with exactly one GAEN service were identified. Statistically equal costs were shown in 30 of 47 service groups. In 10 groups, the cost difference was not relevant (<10%). Cost differences >10% existed only for EGD with variceal therapy, insertion of a self-expanding prosthesis, dilatation/bougienage/exchange with PTC/PTCD in place, non-extensive ERCP, endoscopic ultrasound in the upper gastrointestinal tract, and colonoscopy with submucosal or full thickness resection, or foreign object removal. PCCL differed in all but one group. CONCLUSION: Gastroenterology endoscopy services provided as part of inpatient care but potentially performable on an outpatient basis are predominantly equally expensive for day cases as for patients with a length of stay greater than one day. The disease severity is lower. Calculated §21-KHEntgG cost data thus form a reliable basis for the calculation of appropriate reimbursement for hospital services to be provided as outpatient services under the AOP in the future.

[Limits of the G-DRG system to reflect Complexity in German University Hospitals]. / Die Grenzen des G-DRG-Systems bei der Abbildung von Komplexität in der Universitätsmedizin.

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 (§â€Š21-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 §â€Š21-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.

[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.

[Cost assessment for endoscopic procedures in the German diagnosis-related-group (DRG) system - 5 year cost data analysis of the German Society of Gastroenterology project]. / Kosten endoskopischer Leistungen der Gastroenterologie im deutschen DRG-System ­ 5-Jahres-Kostendatenanalyse des DGVS-Projekts.

Background In the German hospital reimbursement system (G-DRG) endoscopic procedures are listed in cost center 8. For reimbursement between hospital departments and external providers outdated or incomplete catalogues (e. g. DKG-NT, GOÄ) have remained in use. We have assessed the cost for endoscopic procedures in the G-DRG-system. Methods To assess the cost of endoscopic procedures 74 hospitals, annual providers of cost-data to the Institute for the Hospital Remuneration System (InEK) made their data (2011 - 2015; §â€Š21 KHEntgG) available to the German-Society-of-Gastroenterology (DGVS) in anonymized form (4873 809 case-data-sets). Using cases with exactly one endoscopic procedure (n = 274 186) average costs over 5 years were calculated for 46 endoscopic procedure-tiers. Results Robust mean endoscopy costs ranged from 230.56 € for gastroscopy (144 666 cases), 276.23 € (n = 32 294) for a simple colonoscopy, to 844.07 € (n = 10 150) for ERCP with papillotomy and plastic stent insertion and 1602.37 € (n = 967) for ERCP with a self-expanding metal stent. Higher costs, specifically for complex procedures, were identified for University Hospitals. Discussion For the first time this catalogue for endoscopic procedure-tiers, based on §â€Š21 KHEntgG data-sets from 74 InEK-calculating hospitals, permits a realistic assessment of endoscopy costs in German hospitals. The higher costs in university hospitals are likely due to referral bias for complex cases and emergency interventions. For 46 endoscopic procedure-tiers an objective cost-allocation within the G-DRG system is now possible. By international comparison the costs of endoscopic procedures in Germany are low, due to either greater efficiency, lower personnel allocation or incomplete documentation of the real expenses.

Reimbursement in Endoscopy: How Can New Procedures Be Implemented?

BACKGROUND: New procedures in endoscopy take time to be incorporated in the German diagnosis-related groups (DRG) system. Depending on the extent of innovation and the costs, several pathways are possible. METHODS: This article provides an overview of possible pathways to implement new procedures in the German DRG payment system. Additionally, we compare the results of 2 surveys on the system of New Diagnostic and Treatment Methods (Neue Untersuchungs- und Behandlungsmethoden; NUB). Furthermore, the pathways of 2 innovations in endoscopy are described in detail and compared with the possibilities within the legal framework. RESULTS: The different pathways like NUB applications or DRG change requests and the underlying legal framework are described in detail. The results of a survey from 2007 on the daily practice of NUB funding in Germany show that the extent of innovations which receive a positive assessment (status 1) is 46% compared to 43.7% in a survey from 2007, and that 77% of the status 1 procedures (and drugs) can be negotiated into a payment - compared to 53% in the older survey. CONCLUSION: Medical scientific societies should be involved in this process from the beginning. Besides the importance for the hospital application process (81.3% of all medical controllers want to have society support), the regulatory bodies (e.g. DIMDI, InEK, G-BA) also appreciate scientific statements. Two examples show the pathways in detail. For radiofrequency ablation of Barrett's esophagus, the pathway of continuous change requests was chosen, while the endoluminal conduit for the treatment of type 2 diabetes was established as NUB payment.
