Abstract
BACKGROUND With the introduction of the MDK (Medizinischer Dienst der Krankenversicherung) Reform Act, there have been multiple new regulations for hospitals, some of which are confusing and interact with one another. A major focus of the legal changes is directly or indirectly on expanding the provision of outpatient services. OBJECTIVES It can be assumed that-as a result of the new version of the framework conditions and the AOP catalog-the relevant OPS list will be expanded in the future. With the revision of the AOP catalog and the effects of the MDK Reform Act, the number of cases with outpatient potential will increase. Can the effects and challenges for hospitals and especially urology be identified? METHODS Evaluation of official statistics of inpatient and outpatient treatments. Focusing on the problem based on a fictitious practical example from urology. RESULTS A strategy is developed for dealing with cases with outpatient potential and identification of different solutions to compensate for this shift in services and enabling an increase in performance or a deliberate reduction in the provision of services. CONCLUSIONS The choice of the type of service provision is increasingly no longer an issue, and the short-term inpatient treatment of many urological cases is coming under considerable pressure due to political measures such as the MDK Reform Act and the demands of health insurance companies. The reduction of different parts of the inpatient reimbursement for special patient groups must be anticipated. Individual strategies will range from simply not providing outpatient services to complex models of cooperation. This change also means opportunities for hospitals!

Abstract
PURPOSE In patients with open tibial fractures, bone and wound infections are associated with an increased hospital length of stay and higher costs. The infection risk increases with the use of implants. Innovations to reduce this risk include antibiotic-coated implants. This study models whether the use of a gentamicin-coated intramedullary tibial nail is cost-effective for trauma centers managing patients with a high risk of infection. EFFICACY Absolute infection risk and relative risk reduction, by fracture grade, for antibiotic-coated nails compared to standard nails for patients with open tibial fractures were estimated based on the results of a meta-analysis, which assessed the additional benefit of locally-administered prophylactic antibiotics in open tibia fractures treated with implants. The observed efficacy of antibiotic-coated nails in reducing infections was applied in an economic model. METHODS The model compared infection rates, inpatient days, theatre usage and costs in high risk patients, with a Gustilo-Anderson (GA) grade III open fracture, for two patient cohorts from a trauma center perspective, with a 1-year time horizon. In one cohort all GAIII patients received a gentamicin-coated nail whilst GAI and GAII patients received a standard nail. All patients in the comparator cohort received a standard nail. Four European trauma centers provided patient-level data (n=193) on inpatient days, procedures and related costs for patients with and without infections. RESULTS Using the gentamicin-coated nail in patients at high risk of infection (GAIII) was associated with 75% lower rate of infection and cost savings (€477 - €3.263) for all included centers; the higher cost of the implant was offset by savings from fewer infections, inpatient days (-26%) and re-operations (-10%). This result was confirmed by extensive sensitivity analyses. CONCLUSIONS Analyses demonstrated that infection rates and total costs for in-hospital treatment could be potentially reduced by 75% and up to 15% respectively, by using a gentamicin-coated nail in patients at high risk of infection. Fewer infections, reduced inpatient days and re-operations may be potentially associated with use of antibiotic-coated implants. Results are sensitive to the underlying infection risk, with greatest efficacy and cost-savings when the coated implant is used in high risk patients.

Abstract
BACKGROUND AND OBJECTIVES Estimated treatment costs of severely injured patients were often added to registry-based analyses. In the past, the TraumaRegister DGU® used a modular cost estimator for this purpose. A recent research project initiated by the German Trauma Society (DGU) evaluated the reimbursement of severely injured patients in the German DRG system. This project also allowed the generation of an improved update of the registry's cost estimator. METHODS Detailed cost data for the acute therapy of severely injured patients were available from 10 hospitals that also participate in the TraumaRegister DGU®. Cost and registry data were matched using hospital code, date of admission, age, sex, and length of stay. A multivariate regression analysis with hospital costs as dependent variable included patients with an injury severity score (ISS) ≥ 9 points who stayed in hospital at least three days. All injuries were coded using the abbreviated injury scale (AIS). A total of 1002 patients treated in 2007 and 2008 were successfully matched. Cost data was collected for each case according to the method of calculation provided by the German DRG Institute (InEK). RESULTS The mean age was 44 years and 73 % were males; the mean ISS was 27 points. The following aspects were significantly associated with the overall hospital costs: length of stay on the intensive care unit (ICU) (1152 € per day); length on intubation/ventilation (568 € per day); length of stay on normal ward (531 € per day); number of blood products (packed red blood cells; fresh frozen plasma) transfused until ICU admission (258 € per unit); a serious abdominal injury (AIS ≥3; 2849 €); an instable pelvic fracture with relevant blood loss (AIS 5; 7505 €); and a serious injury of the extremities (AIS 3-4; 2418 €). The estimated overall treatment costs calculated by the above mentioned formula averaged 22,138 € per case. The deviation from the measured real costs (21,546 € per case) was less than 3 %. CONCLUSION Using only key data available for all patients in the registry, a valid cost estimator for acute care costs is now available in the TraumaRegister DGU®.

Abstract
Pt-Rh alloy nanoparticles on oxide supports are widely employed in heterogeneous catalysis with applications ranging from automotive exhaust control to energy conversion. To improve catalyst performance, an atomic-scale correlation of the nanoparticle surface structure with its catalytic activity under industrially relevant operando conditions is essential. Here, we present x-ray diffraction data sensitive to the nanoparticle surface structure combined with in situ mass spectrometry during near ambient pressure CO oxidation. We identify the formation of ultrathin surface oxides by detecting x-ray diffraction signals from particular nanoparticle facets and correlate their evolution with the sample's enhanced catalytic activity. Our approach opens the door for an in-depth characterization of well-defined, oxide-supported nanoparticle based catalysts under operando conditions with unprecedented atomic-scale resolution.

Abstract
Background/Objectives: The purpose of this study was to examine the relationship of the proton density fat fraction (PDFF), measured by magnetic resonance imaging (MRI), of supraclavicular and gluteal adipose tissue with subcutaneous and visceral adipose tissue (SAT and VAT) volumes, liver fat fraction and anthropometric obesity markers. The supraclavicular fossa was selected as a typical location where brown adipocytes may be present in humans and the gluteal region was selected as a typical location enclosing primarily white adipocytes. Subjects/Methods: In this cross-sectional study, 61 adults (44 women, median age 29.3 years, range 21–68 years) underwent an MRI examination of the neck and the abdomen/pelvis (3T, Ingenia, Philips Healthcare). PDFF maps of the supraclavicular and gluteal adipose tissue and the liver were generated. Volumes of SAT and VAT were calculated and supraclavicular and subcutaneous fat were segmented using custom-built post-processing algorithms. Body mass index (BMI), waist circumference and waist-to-height ratio were recorded. Statistical analysis was conducted using the Student's t-test and Pearson correlation analysis. Results: Mean supraclavicular PDFF was 75.3±4.7% (range 65.4–83.8%) and mean gluteal PDFF was 89.7±2.9% (range 82.2-94%), resulting in a significant difference (P<0.0001). Supraclavicular PDFF was positively correlated with VAT (r=0.76, P<0.0001), SAT (r=0.73, P<0.0001), liver PDFF (r=0.42, P=0.0008) and all measured anthropometric obesity markers. Gluteal subcutaneous PDFF also correlated with VAT (r=0.59, P<0.0001), SAT (r=0.63, P<0.0001), liver PDFF (r=0.3, P=0.02) and anthropometric obesity markers. Conclusions: The positive correlations between adipose tissue PDFF and imaging, as well as anthropometric obesity markers suggest that adipose tissue PDFF may be useful as a biomarker for improving the characterization of the obese phenotype, for risk stratification and for selection of appropriate treatment strategies.

Abstract
In a meta-analysis of clinical studies, stomatitis did not adversely affect PFS in everolimus-treated patients, and in some studies, trended toward longer PFS than in patients without stomatitis. These results support continued use of everolimus, with dose adjustments and management according to approved prescribing information. Background Everolimus, an oral mammalian target of rapamycin (mTOR) inhibitor, is used to treat solid tumors and tuberous sclerosis complex (TSC). Stomatitis, an inflammation of the mucous membranes of the mouth, is a common adverse event associated with mTOR inhibitors, including everolimus. We conducted a meta-analysis of data from seven randomized, double-blind phase 3 clinical trials of everolimus to determine the clinical impact of stomatitis on efficacy and safety. Patients and methods Data were pooled from the safety sets of solid tumor [breast cancer (BOLERO-2 and BOLERO-3), renal cell carcinoma (RECORD-1), carcinoid tumors (RADIANT-2), and pancreatic neuroendocrine tumors (RADIANT-3)] and TSC studies (EXIST-1 and EXIST-2). Data from solid tumor trials and TSC trials were analyzed separately. Results The rate of stomatitis was 67% in the solid tumor trials (973/1455 patients) and 70% in the TSC trials (110/157 patients). Most stomatitis events were grade 1/2, with grade 3/4 events reported in only 9% (solid tumor trials) and 8% (TSC trials) of patients. Low TSC patient numbers prevented an in-depth evaluation of stomatitis and response. In the solid tumor trials, most first stomatitis episodes (89%; n = 870) were observed within 8 weeks of starting everolimus. Patients with stomatitis occurring within 8 weeks of everolimus initiation had longer progression-free survival (PFS) than everolimus-treated patients without stomatitis in BOLERO-2 {8.5 versus 6.9 months, respectively; hazard ratio (HR), 0.78 [95% confidence interval (CI), 0.62–1.00]} and RADIANT-3 [13.9 versus 8.3 months, respectively; HR, 0.70 (95% CI, 0.48–1.04)]. A similar trend was observed in RECORD-1 [HR, 0.90 (95% CI, 0.66–1.22)] and RADIANT-2 [HR, 0.87 (95% CI, 0.61–1.22)] but not in BOLERO-3 [HR, 1.01 (95% CI, 0.75–1.36)]. Conclusions Stomatitis did not adversely affect PFS, supporting the administration of everolimus in accordance with standard management guidelines.

Abstract
BACKGROUND Most of the current scores and outcome prediction calculations in traumatology are based on the Abbreviated Injury Scale (AIS). However, this is not routinely used for documentation and coding of injuries in many countries, including Germany. Instead of the AIS, the International Classification of Diseases (ICD) is used. While the ICD functions as the basis for automated calculating of the diagnosis-related groups (DRG), no possibility of simple conversion of the 10th version of the ICD into AIS is available so far. OBJECTIVES The aim of this work is to develop and apply a methodology for simple conversion from ICD 10 to current AIS. MATERIALS AND METHODS The developed mapping procedure was based on a 1 : n relationship between trauma codes of ICD-10-GM and the codes of the AIS2005. Calculated ISS from the conversion codes were then compared with the actual ISS coding available from the clinical trauma documentation. RESULTS It can be shown that, despite the considerable differences in the structure and systematic of both classification systems, an automated translation is technically possible. CONCLUSIONS The preliminary result of the mapping suggests, however, that despite the technical feasibility of a reliable conversion and comparability of ICD 10 and AIS in the required quality is still questionable. An automated conversion is still possible and quality would possibly improve by inclusion of additional information.

Abstract
BACKGROUND Due to the heterogeneity of severely injured patients (multiple trauma) it is difficult to assign them to homogeneic diagnosis-related groups (DRG). In recent years this has led to a systematic underfunding in the German reimbursement system (G-DRG) for cases of multiply injured patients. This project aimed to improve the reimbursement by modifying the case allocation algorithms of multiply injured patients within the G-DRG system. METHODS A retrospective analysis of standardized G-DRG data according to §21 of the Hospital Reimbursement Act (§ 21 KHEntgG) including case-related cost data from 3,362 critically injured patients from 2007 and 2008 from 10 university hospitals and 7 large municipal hospitals was carried out. For 1,241 cases complementary detailed information was available from the trauma registry of the German Trauma Society to monitor the case allocation of multiply injured patients within the G-DRG system. Analysis of coding and grouping, performance of case allocation and the homogeneity of costs in the G-DRG versions 2008-2012 was carried out. RESULTS The results showed systematic underfunding of trauma patients in the G-DRG version 2008 but adequate cost covering in the majority of cases with the G-DRG versions 2011 and 2012. Cost coverage was foundfor multiply injured patients from the clinical viewpoint who were identified as multiple trauma by the G-DRG system. Some of the overfunded trauma patients had high intensive care costs. Also there was underfunding for multiple injured patients not identified as such in the G-DRG system. CONCLUSIONS Specific modifications of the G-DRG allocation structures could increase the appropriateness of reimbursement of multiply injured patients. Data-based analysis is an essential prerequisite for a constructive development of the G-DRG system and a necessary tool for the active participation of medical specialist societies.

Abstract
Treatment of bone defects and non-unions frequently requires the transplantation of autologous bone. As an alternative, different kinds of bone substitutes have been used more often during the past years. These bone substitutes include synthetic materials, just as well as processed materials from human donors (allogen) or animals (xenogen). The relatively low hurdles in the approval process, compared to pharmaceutical drugs, have led to an almost unmanageable amount of different kinds of bone substitutes. Due to sparse clinical studies, evidence-based decisions for a specific product or a specific indication are hardly possible. Therefore, a deeper knowledge about basic properties of different bone substitutes is needed for a rational clinical decision. The present review aims to clarify the sometimes confusing nomenclature of bone substitutes and discuss their different biological properties. Generally, bone substitutes can be discriminated in osteogenic, osteoinductive and osteoconductive materials. The great majority of bone substitutes and especially synthetic materials serve as a matrix for bone growth and therefore possess mainly osteoconductive properties. The combination of these osteoconductive materials with osteogenic cells or osteoinductive growth factors, leads to composite materials with higher bone forming potential. Clinically, the quality and vitality of the recipient bone defect is of great importance. As a prerequisite for successful transplantation of bone substitutes or autologous bone, the recipient bone defect should be mechanically stable, free of infection with vital bone ends and intact soft tissue coverage. Bone defects in the spine, methaphyseal defects after trauma/tumour and diaphyseal segmental defects are typical indications for the application of bone substitutes. Unfortunately, the current literature does not allow concrete recommendations for specific bone substitutes or specific clinical indications. However, this review aims to discuss clinical benefits and limitations of bone substitutes for frequent indications to help clinicians in their decision making process.

Abstract
We present the atomic structure of Ir nanoparticles with 1.5 nm diameter at half height and three layers average height grown on graphene/Ir(111). Using surface x-ray diffraction, we demonstrate that Ir nanoparticles on graphene/Ir(111) form a crystallographic superlattice with high perfection. The superlattice arrangement allows us to obtain detailed information on the atomic structure of the nanoparticles themselves, such as size, shape, internal layer stacking and strain. Our experiments disclose that the nanoparticles reside epitaxially on top of the graphene moiré structure on Ir(111), resulting in significant lateral compressive intraparticle strain. Normal incidence x-ray standing wave experiments deliver additional information on the particle formation induced restructuring of the graphene layer.

Abstract
BACKGROUND Orthopedics and trauma surgery are subject to continuous medical advancement. The correct and performance-based case allocation by German diagnosis-related groups (G-DRG) is a major challenge. This article analyzes and assesses current developments in orthopedics and trauma surgery in the areas of coding of diagnoses and medical procedures and the development of the 2012 G-DRG system. METHODS The relevant diagnoses, medical procedures and G-DRGs in the versions 2011 and 2012 were analyzed based on the publications of the German DRG Institute (InEK) and the German Institute of Medical Documentation and Information (DIMDI). RESULTS Changes were made for the International Classification of Diseases (ICD) coding of complex cases with medical complications, the procedure coding for spinal surgery and for hand and foot surgery. The G-DRG structures were modified for endoprosthetic surgery on ankle, shoulder and elbow joints. The definition of modular structured endoprostheses was clarified. CONCLUSION The G-DRG system for orthopedic and trauma surgery appears to be largely consolidated. The current phase of the evolution of the G-DRG system is primarily aimed at developing most exact descriptions and definitions of the content and mutual delimitation of operation and procedures coding (OPS). This is an essential prerequisite for a correct and performance-based case allocation in the G-DRG system.

Abstract
BACKGROUND Critically injured patients are a very heterogeneous group, medically and economically. Their treatment is a major challenge for both the medical care and the appropriate financial reimbursement. Systematic underfunding can have a significant impact on the quality of patient care. In 2009 the German Trauma Society and the DRG-Research Group of the University Hospital Muenster initialised a DRG evaluation project to analyse the validity of case allocation of critically injured patients within the German DRG system versions 2008 and 2011 with additional consideration of clinical data from the trauma registry of the German Trauma Society. Severe deficits within the G-DRG structure were identified and specific solutions were designed and realised. METHODS A retrospective analysis was undertaken of standardised G-DRG data (§ 21 KHEntgG) including case-related cost data from 3 362 critically injured patients in the periods 2007 and 2008 from 10 university hospitals and 7 large municipal hospitals. For 1 241 cases of the sample, complementary detailed information was available from the trauma registry of the German Trauma Society to monitor the case allocation of critically injured patients within the G-DRG system. Analyses of coding and grouping, performance of case allocation, and the homogeneity of costs in the G-DRG versions 2008 and 2011 were done. RESULTS The following situations were found: (i) systematic underfunding of trauma patients in the G-DRG-Version 2008, especially trauma patients with acute paraplegia; (ii) participation in the official G-DRG development for 2011 with 13 proposals which were largely realised; (ii) the majority of cases with cost-covering in the G-DRG version 2011; (iv) significant improvements in the quality of statistical criteria; (v) overfunded trauma patients with high intensive care costs; (vi) underfunding for clinically relevant critically injured patients not identified in the G-DRG system. CONCLUSION The quality of the G-DRG system is measured by the ability to obtain adequate case allocations for highly complex and heterogeneous cases. Specific modifications of the G-DRG structures could increase the appropriateness of case allocation of critically injured patients. Additional consideration of the ISS clinical data must be further evaluated. Data-based analysis is an essential prerequisite for a constructive development of the G-DRG system and a necessary tool for the active participation of medical societies in this process.

Abstract
BACKGROUND The German DRG (diagnosis-related groups) system forms the basis for billing inpatient hospital services. It includes not only the case groups (G-DRGs), but also additional and innovation payments. This paper analyzes and evaluates the relevant developments of the G-DRG System 2010 for orthopedics and traumatology from the medical and classification perspectives. METHODS Analyses of relevant diagnoses, medical procedures and G-DRGs in the versions 2009 and 2010 based on the publications of the German DRG institute (InEK) and the German Institute of Medical Documentation and Information (DIMDI) were carried out. RESULTS The DRG catalog is has grown from 8 to 1,200 G-DRGs. A number of codes for surgical measures have been newly established or modified. Here, the identification and the correct and performance-based mapping of complex and elaborate scenarios was again the focus of the restructuring of the G-DRG system. The G-DRG structure in orthopedics and traumatology has been changed, especially in the areas of spinal surgery and surgery of the upper and lower extremities. The actual impact of the changes may vary depending on the individual hospital services. CONCLUSION For the first time since the introduction of the G-DRG system, the pure numerical changes at the level of DRGs themselves are so marginal that only part of the DRG users in the hospitals will register them. The changes implemented not only a high selectivity between complex and less complex scenarios, but partly also unintended and unjustified revaluation of less complex measures. The G-DRG system has gained complexity again. Especially the G-DRG allocation of spinal surgery and multiple surgical interventions of the upper and/or lower extremities have reached such a complexity that only a few DRG users can follow them.

Abstract
BACKGROUND The 2009 version of the German DRG system brought significant changes for urology concerning coding of diagnoses, medical procedures and the DRG structure. In view of the political situation and considerable economic pressure, a critical analysis of the 2009 German DRG system is warranted. Analysis of relevant diagnoses, medical procedures and G-DRGs in the versions 2008 and 2009 based on the publications of the German DRG-institute (InEK) and the German Institute of Medical Documentation and Information (DIMDI). RESULTS The relevant diagnoses, medical procedures and German DRGs in the versions 2008 and 2009 were analysed based on the publications of the German DRG Institute (InEK) and the German Institute of Medical Documentation and Information (DIMDI). Changes for 2009 focus on the development of the DRG structure, DRG validation and codes for medical procedures to be used for very complex cases. The outcome of these changes for German hospitals may vary depending in the range of activities. CONCLUSION The German DRG system again gained complexity. High demands are made on correct and complete coding of complex urology cases. The quality of case allocation in the German DRG system was improved. On the one hand some of the old problems (e.g. enterostomata) still persist, while on the other hand new problems evolved out of the attempt to improve the case allocation of highly complex and expensive cases. Time will tell whether the increase in highly specialized DRG with low case numbers will continue to endure and reach acceptable rates of annual fluctuations.

Abstract
BACKGROUND Since the introduction of a per-case reimbursement system in Germany (German Diagnosis-Related Groups, G-DRG), the correct reimbursement for the treatment of severely injured patients has been much debated. While the classification of a patient in a polytrauma DRG follows different rules than the usual clinical definition, leading to a high number of patients not grouped as severely injured by the system, the system was also criticized in 2005 for its shortcomings in financing the treatment of severely injured patients. The development of financial reimbursement will be discussed in this paper. METHOD 167 patients treated in 2006 and 2007 due to a severe injury at the University-Hospital Münster and grouped into a polytrauma-DRG were included in this study. For each patient, cost-equivalents were estimated. For those patients treated in 2007 (n=110), exact costs were calculated following the InEK cost-calculation method. The reimbursement was calculated using the G-DRG-Systems of 2007, 2008 and 2009. Cost-equivalents/costs and clinical parameters were correlated. RESULTS A total of 167 patients treated in 2006 and 2007 for a severe injury at the Münster University Hospital and grouped into a polytrauma DRG were included in this study. Cost equivalents were estimated for each patient. For those patients treated in 2007 (n=110), exact costs were calculated following the InEK (Institute for the Hospital Remuneration System) cost calculation method. Reimbursement was calculated using the G-DRG systems of 2007, 2008 and 2009. Cost equivalents/costs and clinical parameters were correlated. DISCUSSION With the ongoing development of the G-DRG system, reimbursement for the treatment of severely injured patient has improved, but the amount of underfinancing remains substantial. As treatment of severely injured patients must be reimbursed using the G-DRG system, this system must be further adapted to better meet the needs of severely injured patients. Parameters such as total surgery time, injury severity score (ISS) and LOS in ICU could be used for this purpose. In future, data obtained in trauma networks can help optimize reimbursement for the treatment of these patients.

Abstract
Semiconductor quantum dots containing two electrons, also called artificial quantum-dot helium atoms, are model structures to investigate the most fundamental many-particle states induced by Coulomb interaction and the Pauli exclusion principle. Here, electronic excitations in quantum-dot helium are investigated by resonant Raman spectroscopy in magnetic fields. We observe transitions from the ground state into the excited singlet state and, in the depolarized Raman configuration which allows spin-flip processes, into the triplet state.

Abstract
BACKGROUND Further developments in the German DRG system have been incorporated into the 2008 version. For ENT medicine and head and neck surgery significant changes concerning coding of diagnoses, medical procedures and concerning the DRG-structure were made. METHODS Analysis of relevant diagnoses, medical procedures and G-DRGs in the versions 2007 and 2008 based on the publications of the German DRG institute (InEK) and the German Institute of Medical Documentation and Information (DIMDI). RESULTS Changes for 2008 focussed on the development of DRG structure, DRG validation and codes for medical procedures. The outcome of these changes for German hospitals may vary depending on the range of activities. CONCLUSION The G-DRG system has gained in complexity again. High demands are made on correct and complete coding of complex ENT and head and neck surgery cases. Quality of case allocation within the G-DRG system has been improved. For standard cases quality of case allocation is adequate. Nevertheless, further adjustments of the G-DRG system especially for cases with complex neck surgery are necessary.

Abstract
BACKGROUND Since 2004, inpatient health care for penetrating eye injuries in Germany had been paid according to the calculated DRG C01Z. Because the extent of treatment mainly derives from the extent of eye damage, this DRG economically summarises very heterogeneous cases. It was the aim to check the cost recovery for the surgical treatment of penetrating eye injuries at a university eye hospital. MATERIAL AND METHODS Performance data for the DRG C01Z were collected for the years 2005 and 2006 using the E1 sheets according to section sign21 KHEntG. Costs for single operations were calculated from fixed and variable costs for the operating theatre and the ward, including costs for personnel and supplies. RESULTS In the 2-year period, out of 4,721 inpatient procedures, 180 perforating eye injuries were surgically treated. In 80 cases, a pure corneal/scleral suture (plus cataract surgery, n=10; mean operating time 67.81 min) was performed. In the other 100 cases, a pars plana vitrectomy (ppV) with adjuvant measures (mean operating time 124.69 min) was needed. Each operation had fixed surgical costs of EUR 130.60; variable costs, including personnel and supplies, varied between EUR 570 for corneal/scleral suture (+/-EUR 250 for combined cataract surgery (n=10) and EUR 1230 (mean) for a ppV. Cost-effective additional adjuncts such as cerclage, perfluorocarbon, gas, silicone oil, or cataract surgery led to extra costs of between EUR 51 and EUR 250 per adjunct (mean EUR 182). At least two of these adjuncts were used in 50% of ppVs, and at least one was used in 90% of ppVs. Hospitalisation costs were about EUR 2184 (EUR 273 per day), with a mean stay of 8 days. The overall costs of an operation for penetrating eye injuries differed significantly in terms of the procedure (corneal/scleral suture: EUR 2662, mean length of stay 7.06 days; ppV: EUR 3712, mean length of stay 8.62 days). Additional costs for multiple surgeries, as occurred in 11.1% of all cases, were not compensated by the DRG system. CONCLUSION In consideration of a relative DRG weight of 1,177 and a base rate of EUR 2723.79 in Bavaria for 2005 and 2006, perforating eye injuries were compensated within the C01Z DRG at EUR 3205,96. Thus, for ppVs no costs are recovered, whereas "pure suture" procedures are overweighted. Due to this inhomogeneity, a split in the C01Z DRG is necessary.

Abstract
BACKGROUND Consequences of the volume outcome relationship are controversial. Objectification based on data analysis is strongly needed. The aim of this publication was to analyse the effects of volume outcome reallocations based on German inpatient data. METHOD The analysis based on inpatient data of the Krankenhauszweckverband Koeln, Bonn und Region (Hospital Association of the Cologne and Bonn Region) of 2002 and 2005. Relevant data sets were identified according to the effects of current German regulations on volume outcome on the special fields liver transplant, kidney transplant, complex pancreatic surgery, and complex oesophageal surgery. RESULTS The effects of current German regulations on volume outcome results differed greatly between the four surgical specialities. There were fewer effects on kidney transplant, but due to an already very high level of centralisation 34% (oesophagus) and 8% (pancreas) of the hospitals stopped related surgery. This affected 8.9% (oesophagus) and 2.2% (pancreas) of related cases. CONCLUSION Concentration and the formation of specialised medical centres are results of the implementation of volume outcome relationships. The quality of medical treatment does not automatically improve from this development. It is necessary to analyse any correlation between quality and frequency of treatment or other criteria such as know-how, structure and process management, and multidisciplinarity.

Abstract
BACKGROUND Since 2004 inpatient health care in Germany is paid according to calculated DRGs. Only a few university hospitals participated in distinct cost calculations of clinical treatment. It was the aim of this study to check the cost recovery at a University Eye Hospital for the surgical treatment of retinal and vitreal diseases by pars plana vitrectomy (ppV), which are included in DRGs C03Z and C17Z. MATERIAL AND METHODS The performance data for both DRGs were collected for the years 2005 and 2006 using the E1 sheets according to section 21 KHEntG. The mean duration of all procedures was collected by data from the internal controlling. Costs for single operations were calculated from fixed and variable costs for the operation theatre and the ward including costs for personnel and material. RESULTS In the 2-year period of 4,721 inpatient procedures 1,307 ppVs were performed. Each ppV had fixed surgical costs of 130.60 EUR; personnel costs varied between 575 EUR (C03Z; including cataract surgery; mean OP duration: 85 min) and 510 EUR (C17Z; no cataract surgery; mean OP duration: 73 min) at a proportion between general anaesthesia and local anaesthesia of 80/20. For a pure ppV material costs were 255 EUR. Additional adjuncts such as an encircling band, perfluorcarbon, ICG, tPA, gas and silicon oil or cataract surgery led to extra costs between 51 EUR and 250 EUR per adjunct und were used in 56% (C03Z) and 74.5% (C17Z) of all procedures. Costs for hospitalisation were about 1765 EUR at a mean residence time of 6.5 days. Thus, the overall costs of a pure basic ppV amounted to 2975 EUR (C03Z) and 2661 EUR (C17Z). In consideration of the current relative DRG weights of 1.08 and 0.957 and a current base rate of 2787.19 EUR in Bavaria, cost recovery is only given for basic ppV but not for complex ppVs having higher material and personnel costs. Additionally, the costs for multiple surgeries as occur in 5.9% of cases are not compensated by the DRG system. CONCLUSION The reimbursement for inpatient ppVs in a University environment is not covered for complex procedures requiring more cost-effective material and personnel time. To consider an adequate cost recovery for these procedures a DRG split for both DRGs (C03Z and C17Z) in basic ppVs and complex ppVs is required. We recommend this proposal for the InEK.

Abstract
BACKGROUND To improve the representation of ENT medicine in the German diagnosis related groups (G-DRG) reimbursement system, the German Association for ENT Medicine and the ENT Professional Medical Association, in cooperation with the DRG-Research Group of the University Hospital of Muenster, undertook a DRG evaluation project. METHOD A retrospective analysis was carried out of the DRG data records from 93,605 cases taken at 39 ENT institutions in 2003. A prospective collection of data from 25,666 cases, including defined expenditure data within a 4 month period in 2004, was also made. RESULTS The number of cases per ENT institution ranged from 274 to 2,556. The mean case-mix was 792.0 and the mean case-mix index was 0.84. A total of 60.5% of the patients were male and 39.5% female, with an average age of 43.3 years. The mean patient clinical and complexity level (PCCL) was 0.72. Considerable adjustments have to be made, especially in oto-, rhino- and sinus-surgery. Allocation according to the complexity of the surgical procedure is mandatory and requires a revision of the German Catalogue of Medical Procedures. A DRG differentiation based on the PCCL should be implemented more frequently. Diagnostic endoscopies should be allocated via surgical partitioning. CONCLUSION The adjustment proposals based on these results will gradually lead to an improved allocation of ENT medical procedures within the G-DRG system in 2006 and later.

Abstract
BACKGROUND When the German DRG system was implemented there was some doubt about whether patients with extensive head and neck surgery would be properly accounted for. Significant efforts have therefore been invested in analysis and case allocation of those in this group. The object of this study was to investigate whether the changes within the German DRG system have led to improved case allocation. METHODS Cost data received from 25 ENT departments on 518 prospective documented cases of extensive head and neck surgery were compared with data from the German institute dealing with remuneration in hospitals (InEK). Statistical measures used by InEK were used to analyse the quality of the overall system and the homogeneity of the individual case groups. RESULTS The reduction of variance of inlier costs improved by about 107.3% from the 2004 version to the 2007 version of the German DRG system. The average coefficient of cost homogeneity rose by about 9.7% in the same period. Case mix index and DRG revenues were redistributed from less extensive to the more complex operations. Hospitals with large numbers of extensive operations and university hospitals will gain most benefit from this development. CONCLUSION Appropriate case allocation of extensive operations on the head and neck has been improved by the continued development of the German DRG system culminating in the 2007 version. Further adjustments will be needed in the future.

Abstract
BACKGROUND The German Diagnosis-Related Groups (DRG) System was further developed into its 2007 version. For orthopedic and trauma surgery, significant changes were made in terms of the coding of diagnoses and medical procedures, as well as in the DRG structure itself. The German Societies for Trauma Surgery and for Orthopedics and Orthopedic Surgery (Deutsch Gesellschaft für Unfallchirurgie, DGU; and Deutsche Gesellschaft für Orthopädie und Orthopädische Chirurgie, DGOOC) once again cooperated constructively with the German DRG Institute InEK. RESULTS Among other innovations, new International Classification of Diseases (ICD) codes for second-degree burns were implemented. Procedure codes for joint operations, endoprosthetic-surgery and spine surgery were restructured. Furthermore, a specific code for septic surgery was introduced in 2007. In addition, the DRG structure was improved. Case allocation of patients with more than one significant operation was established. Further DRG subdivisions were established according to the patients age and the Patient Clinical Complexity Level (PCCL). CONCLUSIONS DRG developments for 2007 have improved appropriate case allocation, but once again increased the system's complexity. Clinicians need an ever growing amount of specific coding know-how. Still, further adjustments to the German DRG system are required to allow for a correct allocation of cases and funds.
