[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.

Splanchnic arterial blood flow is significantly influenced by breathing-assessment by duplex-Doppler ultrasound.

Duplex ultrasound is established for the assessment of mesenteric ischemia but potential influences of breathing on mesenteric arterial blood velocity have not been investigated so far. In 100 patients without abdominal diseases (39 men; age 59.4 ± 18.0 years), peak systolic (PSV), end diastolic velocity (EDV) and resistance index (RI) were assessed in the celiac trunk (CT) and the superior mesenteric artery (SMA) by Doppler ultrasound during expiration and deep inspiration. Expiratory PSVs in the CT and the SMA (153.4 ± 42.5 and 145.3 ± 39.5 cm/s) were significantly higher than inspiratory velocities (135.4 ± 36.8 and 131.9 ± 42.2 cm/s, p < 0.0001 and p = 0.0002), with expiratory PSVs exceeding inspiratory PSVs in more than 75% of patients. The mean percentage of PSV-variation was 21.5% ± 15.3% and 24.6% ± 19.1%, respectively. The study demonstrates that breathing may exert considerable periodic effects on splanchnic arterial hemodynamics. We, therefore, recommend that to prevent an underestimation of arterial stenosis, mesenteric Doppler ultrasound should be performed during expiration.

Self assessment of warning symptoms in upper gastrointestinal bleeding.

INTRODUCTION: Alcohol addicted patients are at increased risk of upper gastrointestinal bleeding. Delay to endoscopy is mainly determined by patients' self assessment. METHODS: The authors asked 417 patients with high alcohol consumption from Leipzig (n = 277) and Munich (n = 140) with an average alcohol consumption of 660 g/week about their behavior when faced with symptoms of acute upper gastrointestinal bleeding. RESULTS: 71% or 51% said they would call the emergency physician if they were to vomit blood or black liquid. Only 32% would call emergency medical aid if they were to pass black stools, and only 25% of those surveyed thought urgent medical attention necessary in any of the three scenarios. Patients with regular contact with health care providers, and women, were more likely to consider these three scenarios as medical emergencies. The authors found no differences by age, educational level, marital status and alcohol consumption. DISCUSSION: Knowledge concerning the impact of symptoms of gastrointestinal bleeding was poor, in our study. Patients with high alcohol consumption and infrequent contact with health care providers, in particular, should be informed about symptoms such as melena and hematemesis, as delayed presentation significantly affects prognosis and resource consumption.
