Rheumatologie im G-DRG-Fallpauschalensystem

On June 27 2000, the German Self-Administration and lately the German Ministry of Health set the general conditions for a new reimbursement system for the inpatient hospital sector which is based nearly exclusively on lump-sum payments. The Association of Acute Rheumatology Hospitals (VRA) and the DRG-Research-Group, Münster University Hospital, conducted a multi-center trial which included 7266 cases from 22 different hospitals. The data were used to analyze how well the not yet German healthcare adjusted G-DRG system (version 1.0) accounts for rheumatologic diagnostics and treatment as well as problems of specialized hospitals. 7 Adjacent-DRGs covered 91% of all cases, 68% of all cases were grouped into only two different Adjacent-DRGs (169 Bone Diseases and Specific Arthropathies and 166 Other Connective Tissue Disorders). Groups with different complexity which are not appropriately covered by the existing G-DRG system could be identified. The data further revealed a systematically longer length of stay in rheumatology clinics opposed to the average length of stay in the data used for calculating the G-DRGs, due to different structures and procedures of the complex rheumatologic treatment. The results strongly supported the assumption that an accurate reimbursement of rheumatologic cases in the current G-DRG system 1.0 would not have been possible. Adaptations made in the new G-DRG Version 2004 can only partly solve these problems, despite an improved construction of the DRGs. In order to guarantee an appropriate reimbursement of rheumatology clinics from 2005 on, the G-DRG system must be adapted to specific rheumatological pathways and/or alternative or additional reimbursement systems have to be found.     

Das G-DRG-System 2008

The G-DRG system 2008 once again brings many changes to rheumatological departments in Germany. The following article presents the main general and specific changes in the G-DRG system, as well as in the classification systems for diagnoses and procedures and in invoicing for 2008. Since the G-DRG system is only a tool for the redistribution of resources, every hospital needs to analyze the economic effects of the system by applying the G-DRG transition grouper to its own cases. Depending on their clinical focus, rheumatological departments may experience positive or negative effects from the system's application. The strain placed on hospitals by the inadequate funding of increased costs needs to be assessed separately from the effects of redistribution by the G-DRG system.     

Funktionelle Insulintherapie (FIT) beim Typ-1-Diabetes

The goal of insulin treatment in patients with type 1 diabetes mellitus is to achieve near-normal blood glucose levels and avoid severe hypoglycaemic episodes, so as to prevent micro- and macrovascular complications and achieve a good quality of life. Functional insulin therapy together with the short- and long-acting analogue insulins now available offers patients with type 1 diabetes mellitus a treatment option that simulates physiological insulin substitution very closely. An insulin pump allows further refinement of the insulin dose administered. Functional insulin therapy allows the patient greater autonomy in self-treatment and much more flexibility in activities of daily living. Conversely, frequent and regular self-monitoring of blood glucose levels is crucial to the successful implementation of functional insulin therapy.     

Comparison of tissue Doppler and propagation velocity to invasive measures for measuring left ventricular filling pressures

The utility of tissue Doppler and propagation velocity in identifying patients with abnormal left ventricular filling pressures was assessed in 50 patients who underwent catheterization and echocardiography on the same day. The ratios of the peak velocity of early mitral inflow to early mitral annular velocity (E/Ea) and the velocity of propagation (E/Vp) were compared with invasive measurements of pre-A-wave left ventricular pressures. Echocardiography measures were 77% to 92% accurate in identifying patients with a pre-A-wave pressure >15 mm Hg. Tissue Doppler imaging is more accurate than propagation velocity.

Combined Deletion of Vhl and Kif3a Accelerates Renal Cyst Formation

A subset of familial and sporadic clear cell renal cell carcinomas (ccRCCs) is believed to develop from cystic precursor lesions. Loss of function of the von Hippel-Lindau tumor suppressor gene (VHL) predisposes renal epithelial cells to loss of the primary cilium in response to specific signals. Because the primary cilium suppresses renal cyst formation, loss of the cilium may be an initiating event in the formation of ccRCC. To test this hypothesis, we analyzed the consequences of inducible renal epithelium–specific deletion of Vhl together with ablation of the primary cilium via deletion of the kinesin family member 3A (Kif3a) gene. We developed a microcomputed tomography–based imaging approach to allow quantitative longitudinal monitoring of cystic burden, revealing that combined loss of Vhl and Kif3a shortened the latency of cyst initiation, increased the number of cysts per kidney, and increased the total cystic burden. In contrast with findings in other cystic models, cysts in Kif3a mutant mice did not display accumulation of hypoxia-inducible factor 1-α (HIF1α), and deletion of both Hif1a and Kif3a did not affect cyst development or progression. Vhl/Kif3a double mutation also increased the frequency of cysts that displayed multilayered epithelial growth, which correlated with an increased frequency of misoriented cystic epithelial cell divisions. These results argue against the involvement of HIF1α in promoting renal cyst growth and suggest that the formation of simple and atypical renal cysts that resemble ccRCC precursor lesions is greatly accelerated by the combined loss of Vhl and the primary cilium.     

Incidence and Survival Patterns of Sinonasal Undifferentiated Carcinoma in the United States

Objective To determine trends in sinonasal undifferentiated carcinoma (SNUC) survival patterns in the United States. Design Retrospective review of national database. Participants All cases of SNUC in the National Cancer Institute''s Surveillance Epidemiology and End Results program from 1973 to 2010 were examined. Main Outcome Measures Age-adjusted incidence and survival rates were calculated and stratified by demographic information and treatment modality. Cohort analysis was performed to analyze survival patterns over time. Results A total of 318 SNUC cases were identified. Age-adjusted incidence rate (IR) was 0.02 per 100,000. Incidence was greater in males (IR: 0.03) than females (IR: 0.01; p = 0.03). Overall 5- and 10-year relative survival rate was 34.9% and 31.3%, respectively. Overall median survival was 22.1 months. Median survival following surgery combined with radiation was 41.9 months. Five-year relative survival rate following surgery, radiation, or surgery combined with radiation was 38.7%, 36.0%, and 39.1%, respectively. Median survival from 1973–1986 and 1987–2010 was 14.5 and 23.5 months, respectively. Conclusions This study provides new data regarding survival patterns of SNUC in the United States, confirming survival benefit with surgery and radiation as well as identifying a trend toward improved survival in recent decades.
