[Quality in acute inpatient rheumatology 2021 : Current aspects of the KOBRA quality label of the Association of Rheumatological Acute Care Clinics]. / Qualität in der akutstationären Rheumatologie 2021 : Aktuelle Aspekte zum KOBRA-Qualitätslabel des Verbandes Rheumatologischer Akutkliniken (VRA e.V.).

A comprehensive health policy quality campaign launched in 2021 aims to improve the quality and transparency of hospital care for people with diseases in Germany. Legal requirements for minimum volumes and the expansion of quality contracts between cost units and hospitals as well as the use of quality indicators relevant to planning for demand-oriented and quality-oriented further development of inpatient care will increase competition in the quality of care between hospitals. The topic of development and definition of quality in medicine was also comprehensively addressed by the Association of Rheumatological Acute Care Clinics (VRA) shortly after its foundation in 1998. At the center of acute inpatient quality management are binding structural criteria linked to the continuous outcome benchmarking in acute rheumatology care (KOBRA) project launched in 2003 in rheumatology (and continuously implemented to date) measuring process and outcome quality. Based on this framework (fulfillment of the structural quality and participation in the KOBRA project) successfully participating rheumatology units can acquire the KOBRA seal of approval for 2 years at a time, which is awarded by the project management, the aQua Institute. The outstanding position of the project is exemplified by data evaluation on treatment change in active rheumatoid arthritis, diagnosis confirmation of connective tissue diseases and vasculitis during the inpatient stay as well as on participatory decision-making processes concerning rheumatoid arthritis (referring to the results of the data collection period 2018). By anchoring projects for structural, process and outcome quality acute inpatient rheumatology is well prepared for the paradigm shift demanded by health policies. Additionally, the KOBRA project is a good prerequisite to meet the requirements concerning quality management fixed in the Federal Joint Committee (G-BA) guidelines for recognition as a rheumatology center.

[Traumatology in the elderly : Multimodal prevention of delirium and use of augmentation techniques]. / Alterstraumatologie : Multimodale Delirprävention und Verwendung von Augmentationstechniken.

Recent data show that 20-80% of surgery patients are affected by delirium during inpatient clinical treatment. The medical consequences are often dramatic and include a 20 times higher mortality and treatment expenses of the medical unit increase considerably. At the University Hospital of Münster a multimodal and interdisciplinary concept for prevention and management of delirium was developed: all patients older than 65 years admitted for surgery are screened by a specialized team for the risk of developing delirium and treated by members of the team if there is a risk of delirium. Studies proved that by this multimodal approach the incidence of delirium was lowered and therefore the quality of medical care improved.When surgical treatment of fractures in the elderly is required, limited bone quality as well as pre-existing implants can complicate the procedure. Secondary loss of reduction after osteosynthesis and avulsion of the implant in particular must be prevented. Augmentation of the osteosynthetic implant with bone cement can increase the bone-implant interface and therefore stability can be improved. Additional intraoperative 3D imaging can be necessary depending on the localization of the fracture. In biomechanical studies we could prove greater stability in the osteosynthesis of osteoporotic fractures of the distal femur when using additional bone cement; therefore, the use of bone cement is an important tool, which helps to prevent complications in the surgical treatment of fractures in the elderly. Nevertheless, special implants and technical skills are required and some safety aspects should be considered.

Electrooptical Absorption Measurements (EOAM) Testify Existence of two Conformers of Prodan and Laurdan with Different Dipole Moments in Equilibrium Ground and Franck-Condon Excited State.

The results from the electrooptical absorption measurements (EOAM) on the equilibrium ground and excited Franck-Condon state dipole moments of Prodan and Laurdan in 1,4-dioxane are presented. As follows from experiments Prodan and Laurdan in the equilibrium ground and excited Franck-Condon state have two conformers with considerably different dipole moments. The electrical dipole moments and the transition dipole moment, obtained from the short-wavelength region of the absorption spectrum are parallel. The electrical dipole moments measured at the long-wavelength spectral region are parallel to each other but not parallel to the transition dipole moment m a. The angle θ between the transition dipole moment m a and the dipole moment in the equilibrium ground state µ g of the long-wavelength conformer is about 30(0) for both probes. Obtained results evidence that donor-acceptor pairs of the short-wavelength and long-wavelength conformers are not located on the same axis. Two low-energy conformers of Prodan have been found by density functional theory (DFT) calculations, differing in the orientation of the carbonyl group towards the naphthalene system.

[Hospital financing in 2016. Relevant changes for rheumatology]. / Krankenhausfinanzierung 2016. Relevantes für die internistische Rheumatologie.

Hospital financing 2016 will be influenced by the prospects of the approaching considerable changes. It is assumed that the following years will lead to a considerable reallocation of financial resources between hospitals. While not directly targeted by new regulations, reallocations always also affect specialties like rheumatology. Compared to the alterations in the legislative framework the financial effects of the yearly adaptation of the German diagnosis-related groups system are subordinate. Only by comprehensive consideration of current and expected changes a forward-looking and sustainable strategy can be developed. The following article presents the relevant changes and discusses the consequences for hospitals specialized in rheumatology.

[Hospital financing in 2015. Relevant changes for rheumatology]. / Krankenhausfinanzierung 2015. Relevantes für die internistische Rheumatologie.

The announced major reforms will most probably not have an impact on hospital financing before 2016. Nevertheless, the numerous minor changes in the legislative framework and the new version of the German diagnosis-related groups (G-DRG) system can be important for hospitals specialized in rheumatology. The following article presents the relevant changes and discusses the consequences for hospitals specialized in rheumatology.

[Implementation of electronic health records at a tertiary care eye hospital]. / Implementierung einer elektronischen Patientenakte an einer deutschen Augenklinik der Maximalversorgung.

BACKGROUND: Although electronic health records (EHR) were introduced into ophthalmology practices many years ago, paper-based medical records are still common in most tertiary care eye hospitals. MATERIAL AND METHODS: We report on the implementation of an EHR system at the university eye hospital in Münster in the time period between January and December 2013. RESULTS: Advantages of an EHR system in the setting of a university eye hospital include ubiquitous access to patient data, structurability as well as scientific interpretability. Data safety, personnel and financial investment and integration into existing hospital software systems represent the main challenges. CONCLUSION: The EHR system will replace paper-based records in the future. In view of the high need for visualization and recording of medical findings, EHR software solutions seem promising particularly in ophthalmology.

[Quality of case allocation of orthopedics and trauma surgery in the 2004 and 2014 versions of the German DRG system. An interim assessment of the development process]. / Abbildung orthopädisch-unfallchirurgischer Leistungen in den G-DRG-Systemversionen 2004 und 2014. Eine Zwischenbilanz des Weiterentwicklungsprozesses.

BACKGROUND: Since 2004 the German diagnosis-related groups (DRG) system has been applied nationwide in all German somatic hospitals. The G-DRG system is updated annually in order to increase the quality of case allocation. What developments have occurred since 2004 from the perspective of orthopedics and trauma surgery? This article takes stock of the developments between 2004 and 2014. METHODS: Analysis of relevant diagnoses, medical procedures and G-DRGs in the versions 2004 and 2014 based on the publications of the German DRG Institute (InEK) and the German Institute of Medical Documentation and Information (DIMDI). RESULTS: The number of G-DRGs in the whole system increased by 45.1 % between 2004 and 2014. The number of G-DRGs in the major diagnostic category (MDC) 08 that contains the majority of orthopedic and trauma surgery categories increased in the same period by 61.6 %. The reduction of variance of inlier costs in the MDC 08 category, a statistical measure of the performance of the G-DRG system, was below the corresponding value of the total system in 2004 as well in 2014. However, the reduction of variance of inlier costs in MDC 08 (+ 30.0 %) rose more from 2004 to 2014 than the corresponding value of the overall system (+ 21.5 %). CONCLUSION: Many modifications of the classification systems of diagnoses (ICD-10-GM) and medical procedures (OPS) and the structures of the G-DRG system could significantly improve the quality of case allocation from the perspective of orthopedics and trauma surgery between 2004 and 2014. Th assignment of cases could be differentiated so that complex cases with more utilization of resources were allocated to higher rated G-DRGs and vice versa. However, further improvements of the G-DRG system are necessary. Only correct and complete documentation and coding can provide a high quality of calculation of costs as a basis for a correct case allocation in future G-DRG systems.

[Hospital financing in 2014. Relevant changes for rheumatology]. / Krankenhausfinanzierung 2014. Relevantes für die internistische Rheumatologie.

As with others medical disciplines hospitals specialized in rheumatology again face heavy economic burdens in 2014. To meet the challenges knowledge of the new German diagnosis-related groups (G-DRG) system, the legislative framework and current jurisprudence can be helpful. The following article presents the major changes and discusses the consequences for hospitals specialized in rheumatology.

[Geocoding of routine data. Where are my referring physicians and what are my competitors doing?]. / Geocoding von Routinedaten. Wo sind meine Zuweiser und was machen meine Mitbewerber?

Modern methods of reporting include the visualization of data concerning patients and referring doctor's residence and other clinical data with geographical reference. Thus, static and dynamic information about catchment areas and their changes can be visualized as well as answers to the important question for your main referring practicing physicians and possible changes in their behavior. Apart from the purely operational significance for the hospital, we also find important strategic aspects that include issues concerning hospital perspectives and possibilities, e.g., for the planning of collaborations. Overall, the method represents a useful addition to conservative forms of controlling reports in the hospital.

[Hospital financing in 2013: relevant changes for rheumatology]. / Krankenhausfinanzierung 2013 : Relevantes für die internistische Rheumatologie.

Hospital financing is again subjected to a multitude of reforms that can be of relevance for rheumatology in 2013. Besides changes in the German diagnosis-related group (G-DRG) classification system and coding, modifications in the legislation and legal framework conditions have a growing impact on the economic situation and strategy of hospitals. The following article presents the major changes and discusses consequences for hospitals specialized in rheumatology.

[Description of the severely injured in the DRG system: is treatment of the severely injured still affordable?]. / Abbildung von Schwerverletzten im DRG-System : Wird die Schwerverletztenversorgung doch bezahlbar?

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.

[The challenge of adequate reimbursement for the seriously injured patient in the German DRG system]. / Die Herausforderung der sachgerechten Vergütung von Schwerverletzten im deutschen DRG-System.

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.

Shaping the System - The DRG Evaluation Project of the German Society for Gynaecology and Obstetrics (Deutsche Gesellschaft für Gynäkologie und Geburtshilfe, DGGG).

Introduction: The German DRG system is annually adapted to the changing services provided. For the further development, the self-governing body and its DRG Institute (InEK) depend on participation of the users. Methods: For one of the DRG evaluation projects initiated by DGGG, cost and performance data for the year 2011 from 16 hospitals were available. After plausibility checks and corrections, analyses for service and cost homogeneity were performed. In cases of inadequate DRG-representation attributes were sought that would make an appropriate reimbursement possible. Conspicuities and potential solutions were checked for clinical plausibility. Results: 44 concrete modification proposals for further development of the G-DRG system were formulated and submitted in due time to the InEK. In addition, 3 modification proposals were addressed to the German Institute for Medical Documentation and Information (Deutsches Institut für Medizinische Dokumentation und Information, DIMDI) for further development of the diagnosis classification ICD-10-GM. For all modification proposals care was taken to minimise misdirected incentives and to reduce the potential for disputes with the cost bearers and their auditors services in settlements. Discussion: The publication of the G-DRG system 2014 shows which modification proposals have been realised. Essentially, an appropriate redistribution of the resources among the gynaecological and obstetrics departments is to be expected. The financial pressure that is caused by the generally inadequate financing of hospitals will not be reduced by a further development of the G-DRG system.

[Orthopedic and trauma surgery in the German DRG system. Recent developments]. / Orthopädie und Unfallchirurgie im deutschen DRG-System. Aktuelle Entwicklungen.

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.

[Complexity level simulation in the German diagnosis-related groups system: the financial effect of coding of comorbidity diagnostics in urology]. / Schweregradsimulation im G-DRG-System : Die finanziellen Auswirkungen der Nebendiagnosenkodierung in der Urologie.

BACKGROUND: Precise and complete coding of diagnoses and procedures is of value for optimizing revenues within the German diagnosis-related groups (G-DRG) system. The implementation of effective structures for coding is cost-intensive. The aim of this study was to prove whether higher costs can be refunded by complete acquisition of comorbidities and complications. METHODS: Calculations were based on DRG data of the Department of Urology, University Hospital of Münster, Germany, covering all patients treated in 2009. The data were regrouped and subjected to a process of simulation (increase and decrease of patient clinical complexity levels, PCCL) with the help of recently developed software. RESULTS: In urology a strong dependency of quantity and quality of coding of secondary diagnoses on PCCL and subsequent profits was found. Departmental budgetary procedures can be optimized when coding is effective. The new simulation tool can be a valuable aid to improve profits available for distribution. Nevertheless, calculation of time use and financial needs by this procedure are subject to specific departmental terms and conditions. CONCLUSIONS: Completeness of coding of (secondary) diagnoses must be the ultimate administrative goal of patient case documentation in urology.

[Hospital financing in 2012 - Relevant changes for rheumatology]. / Krankenhausfinanzierung 2012 - Relevantes für die Internistische Rheumatologie.

The following article presents the major general and specific changes for the financing of rheumatology in Germany for 2012. Besides relevant changes in the German diagnosis-related groups (G-DRG) classification system and for the coding, the new legislation and the resulting incentives are covered. The consequences for hospitals specialized in rheumatology are discussed.

[Financing of inpatient orthopaedics and trauma surgery in the 2011 G-DRG System]. / Finanzierung der stationären Orthopädie und Unfallchirurgie im G-DRG-System 2011.

BACKGROUND: The German DRG system forms the basis for billing inpatient hospital services. It includes not only the case groups (G-DRGs), but also copayments. This paper analyses and evaluates the relevant developments of the 2011 G-DRG system for orthopaedics and traumatology from the medical and classificatory perspective. METHODS: An analysis was performed of relevant diagnoses, medical procedures and G-DRGs in the 2010 and 2011 versions based on the publications of the German DRG Institute (InEK) and the German Institute of Medical Documentation and Information (DIMDI). RESULTS: A number of codes for surgical measures have been newly established or modified - above all in foot surgery, arthroscopic surgery and wound surgery. 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 orthopaedics and traumatology is changed, especially for polytraumata. CONCLUSION: The allocation of common cases with a standardized treatment pattern appears to be appropriate and the reimbursement adequate. For the less common and more complex cases the 2011 G-DRG system still shows need for further modification (e.g. polytraumata, joint replacement, spine surgery). The proper integration of the modified OPS classification for foot surgery to the appropriate G-DRGs will be essential to maintain the high quality of the reimbursement structure for the future.

[Hospital financing for 2011: relevant changes in rheumatology]. / Krankenhausfinanzierung 2011 : Relevantes für die Rheumatologie.

The following article presents the major general and specific changes for rheumatology in the financing of inpatient care in Germany for 2011. In addition to relevant changes in the G-DRG classification system and coding, the new legislation and insurance company auditing procedures are covered. The impact these changes will have on hospitals specialized in rheumatology is discussed.

[Financing of inpatient orthopedics and trauma surgery in the G-DRG system 2010]. / Finanzierung der stationären Orthopädie und Unfallchirurgie im G-DRG-System 2010.

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.
