Even in the era of modern guidelines, the treatment of rheumatic diseases is only as good as the framework of rheumatological care within which the treatment is carried out. The access to high-quality medical treatment for all patients is therefore essentially decisive for the prognosis of the patients. This article describes the current state of outpatient treatment in rheumatology and demonstrates which quality projects, such as treatment contracts, outpatient specialized medical treatment (ASV), digitalization and training as specialized rheumatological assistant (RFA), have been created in order to ensure the treatment of our patients. Furthermore, standards are defined that can guarantee a contemporary and guideline-conform treatment in outpatient rheumatological units. As an example it is an affirmation of the Professional Association of German Rheumatologists (BDRh) for ensuring optimal care for all rheumatology patients through early or emergency rheumatology clinics, treat to target, appropriate delegation of medical duties and diversification of treatment, thus an assurance of the quality and comprehensive treatment in rheumatology. The important topic of safeguarding the next generation of rheumatologists, which is indispensable for this, is also discussed.

From the perspective of patients with rheumatic diseases, the reduction of inflammatory disease activity alone is not a sufficient treatment goal. In addition the functional health and participation also have to be improved. Starting with the first symptoms the empowerment for the self-management of the disease is important for the patients; therefore, the established treat to target-strategy has to be expanded by the functional dimension to treat to participation. The position paper of the German Society for Rheumatology (GSR) summarizes the relevant fields of the multiprofessional action that is frequently necessary. This includes the acquirement of function-related competencies during training, further education and advanced training as well as implementation in the everyday practice of patient care. Furthermore, the GSR acknowledges the need for research related to functional and sociomedical consequences of rheumatic diseases and to individual and combined function-related programs in outpatient and inpatient care in rheumatology.

Rheumatic diseases in childhood and adolescence differ from those of adulthood according to type, manifestation, treatment and course. A specialized therapy, starting as early as possible, improves the prognosis, can prevent long-term damage and saves the costs of long-term care. Only a specialized pediatric care system can guarantee optimum quality of the processes involved and the results for rheumatology in childhood and adolescence within a global financial system. This requires adequate structural quality of the specialized clinics and departments for pediatric rheumatology. The management of rheumatic diseases in childhood and adolescence is comprehensive and requires a multidisciplinary, specialized and engaged team which can cover the whole spectrum of rheumatic diseases with their various age-dependent aspects. In order to guarantee an adequate, cost-efficient routine, a specialized center which concentrates on inpatient care should treat at least 300 patients with pediatric rheumatic diseases per year. The diagnoses should be divided among the various disease categories with at least 70% of them involving inflammatory rheumatic diseases. For the inpatient care of small children, an accompanying person (parent) is necessary, requiring adequate structures and services. Patient rooms as well as diagnostic (radiography, sonography, etc.) and therapeutic services (physiotherapy, occupational therapy, pool, etc.) must be adequate for small children and school children as well as adolescents. Suitable mother-child units must also be provided and a school for patients is required within the clinic. A pediatric rheumatologist must be available 24 h a day, and it must be possible to reach other specialists within a short time. For painful therapeutic procedures, age-appropriate pain management is obligatory. A continuous adjustment of these recommendations to changing conditions in health politics is intended.

Background: With the introduction of tumor necrosis factor (TNF) alpha inhibitors, the treatment of inflammatory rheumatic diseases (IRD) has undergone a fundamental change. Several of the originally high-priced biologics are now accessible as lower cost biosimilars, removing a significant impediment to prescription., Objective: The present study investigated whether the availability of biosimilars is associated with an improvement in the care of IRD. Moreover, the subjective acceptance of biosimilars by physicians and patients was investigated and compared with objectifiable parameters., Material and Methods: Pseudonymized claims data of the Bavarian Association of Statutory Health Insurance Physicians from 2014 to 2019 as well as a paper and pencil survey of patients and rheumatologists formed the data basis of the study., Results: During the observation period, the proportion of diagnosed patients receiving drug therapy increased from 38.5% to 43.2%. Also, the care changed in terms of the prescribed agents. Conventional drug therapy declined overall and, in particular, glucocorticoid prescriptions decreased from 39.3% in 2014 to 34.3% in 2019. At the same time, the proportion of targeted treatments increased from 12.3% to 20.4%. The median duration of basic treatment before first-time bDMARD use dropped from 3.15 years in 2014 to 2.17 years in 2019., Conclusion: Over the observation period, in which three biosimilars entered the market, the care of patients with IRD improved both quantitatively and qualitatively. The market share of biosimilars increased in parallel with this development. With an overall high acceptance of biosimilars, the assessment of the disease course by physicians and patients indicates a slight subjectively perceived advantage of therapy with originals compared to biosimilars, which, however, is not confirmed when standardized scores are applied. A possible explanation for this might be a nocebo effect, which could be minimized by suitable communication strategies., (© 2022. The Author(s).)

Background: In March 2020 the SARS-CoV‑2 pandemic disseminated initially especially in Bavaria. At that time data on patients with rheumatic diseases and immunomodulatory treatment was lacking., Objective: The aim was to analyze the influence of the SARS-CoV‑2 pandemic on the clinical treatment strategy., Material and Methods: Between 16 March and 31 July 2020 all patients who consecutively presented at the rheumatology outpatient clinic of the Klinikum rechts der Isar of the Technical University of Munich were included in the study. Individual treatment adjustments were based on clinical judgment and the recommendations for action of the German Society for Rheumatology (DGRh)., Results: A total of 322 patients were included. The most frequent diagnosis was rheumatoid arthritis with 17%, ANCA-associated vasculitis (AAV) with 14% and SLE with 12%. Of the patients 262 were on DMARD treatment and 77 received oral glucocorticoids. There were 5 cases of suspected SARS-CoV‑2 infection; however, no patient verifiably became ill due to COVID-19. In 40 patients, treatment adjustments were done due to the pandemic, whereby 3 patients developed a flare of the underlying disease. In retrospect, treatment de-escalation occurred most frequently in AAV, IgG4-related disease, immunosuppressive treatment with rituximab and the simultaneous presence of malignant diseases., Conclusion: The total lack of confirmed SARS-CoV‑2 infections in an otherwise strongly affected region could indicate that the infection risk for SARS-CoV‑2 is not substantially increased for patients with inflammatory rheumatic diseases. A continuation of most immunosuppressive medications therefore seems reasonable during the ongoing pandemic.

Only the correct diagnosis enables an effective treatment of rheumatic diseases. Digitalization has already significantly accelerated and simplified our everyday life. An increasing number of digital options are available to patients and medical personnel in rheumatology to accelerate and improve the diagnosis. This work gives an overview of current developments and tools for patients and rheumatologists, regarding digital diagnostic support in rheumatology., (© 2021.

Background: The initial presentation of patients with symptoms indicative of a rheumatic disease is in most cases not directly to a rheumatologist. This study evaluated the following questions: I. Which medical specialists refer patients to a department of rheumatology? II. Evaluation of the accordance of the presumptive referral diagnosis and the final diagnosis by a rheumatologist., Methods: A total of 947 patients (279 men and 668 women) who initially presented to a university hospital for rheumatological diagnostics were included in the study. The referring medical specialist fields were identified. Furthermore, a kappa analysis was performed to evaluate the accordance of the presumptive referral diagnosis and the final diagnosis generated after a rheumatological evaluation of the patients., Results: Of the referrals 73% were initiated by general practitioners or internists functioning as general practitioners. The other referrers were 5% specialists in internal medicine (excluding rheumatology), 4% orthopedic/trauma surgeons, 1% other surgeons and 4% other specialist fields. A rheumatological diagnosis was made in 58% of the patients and rheumatological inflammatory joint diseases (26%), collagenosis (14%) and vasculitides (5%) were the most frequently diagnoses. The accordance of the presumptive diagnosis of the general practitioners and the final diagnosis after rheumatological evaluation was a kappa coefficient of κ = 0.304. Lower kappa values were evaluated for orthopedic surgeons (κ = 0.277) and other specialists (κ = 0.200)., Conclusion: The referrals to a rheumatology institution were frequently initiated by general practitioners and internists functioning as general practitioners. In this context the presumptive diagnosis of general practitioners showed a low accordance with the final rheumatological diagnosis. In contrast, a detailed presumptive diagnosis is desirable for optimal use of the limited resources for rheumatological care.

Background and Objective: The work environment for rheumatologists has significantly changed over the last years. The healthcare of patients with rheumatic diseases is at risk due to the age structure of specialized rheumatologists in middle Germany and the limited availability of training positions for rheumatologists. In this context, it is important to have detailed information on the resident physicians in rheumatology concerning their own visions regarding their future professional career., Material and Methods: A questionnaire was sent to resident physicians in 25 rheumatology training hospitals in the middle of Germany (Saxony, Saxony-Anhalt and Thuringia). The questionnaire was completed and returned by 27 participants (17 women and 10 men)., Results: Most of the participants (60%) aimed to qualify as a specialist in internal medicine followed by a specialization in rheumatology (altogether training for a minimum of 8 years). After finishing training 44% would prefer to work in an outpatient setting while 30% planned to work in a combined outpatient and clinical setting. Of the participants 48% would prefer to work as part-time rheumatologists and 74% (women 94% and men 40%) were interested in employment in an outpatient medical healthcare center. The compatibility of family and work as well as the work-life balance was considered to be highly relevant for the future professional life., Conclusion: Less than half of the participants intended to work exclusively in an outpatient setting after completing the training in rheumatology. In addition, the participants preferred a part-time employment with compatibility of professional and private life. Consequently, alternative models of employment should be created in rheumatology to be attractive for future physicians. On the other hand, the study revealed that the independent rheumatological practice has a lower priority for the young rheumatologists taking part in this survey.

Background: Infections are one of the most common clinical problems in patients with rheumatic diseases who need to be treated with glucocorticoids in an intensive care unit. To date, there are no recommendations for the standardized control of glucocorticoid treatment in such situations., Objective: Based on a literature search this paper provides an overview of evidence-based and eminence-based recommendations for the control of glucocorticoid treatment under intensive care conditions using the example of systemic lupus erythematosus., Methods: A systematic literature search was carried out using a MeSH term search in the PubMed database., Results: Infections are one of the most common causes for the treatment of patients with rheumatic diseases in intensive care units. In the case of systemic lupus erythematosus it is particularly challenging to distinguish the infection from increased disease activity or to treat the parallel occurrence. Patients in an intensive care unit are exposed to an increased level of physical stress due to the severity of the disease, which is why special attention should be paid to symptoms of adrenocortical insufficiency. Evidence-based recommendations for prophylaxis of an adrenal crisis only exist in relation to perioperative procedures and not for the situation of severe infections., Conclusion: The use of glucocorticoids in systemic lupus erythematosus is often chronic and there is an increased risk of infections. In the case of infections (or simultaneous disease flare) adequate anti-infective treatment should be administered, the treatment with glucocorticoids should be adjusted accordingly and symptoms of adrenocortical insufficiency should simultaneously be looked for.

Background: Children and adolescents with inflammatory rheumatic diseases have a disease and treatment-related increased risk of infections. This risk includes vaccine-preventable diseases; therefore, vaccinations represent an important preventive measure against infection in these patients. However, approximately one in three patients with a juvenile rheumatic disease is nowadays still inadequately vaccinated, mostly due to uncertainty regarding the efficacy and safety of vaccination in these patients., Objectives: This paper summarizes the available evidence regarding the efficacy and safety of vaccinations in children and adolescents with rheumatic diseases and gives recommendations for the clinical practice., Results and Perspectives: Almost 2000 children and adolescents with rheumatic diseases were examined in the more than 30 previously published vaccination studies, comprising nearly all standard vaccinations in the immunization schedule. The immunogenicity was usually sufficient and there was no evidence of a relevant aggravation of the underlying disease. Recommendations for the clinical practice are given also considering data beyond pediatric rheumatology; however, a final benefit-risk assessment is not yet possible.

The growing burden of chronic disease and the current nature of healthcare systems which are structurally ill-equipped to cater to the complex needs of patients with chronic conditions has led to governments and healthcare providers seeking alternative ways to improve patients own capacity to actively self-manage their chronic condition. In Australia, there has been a focus on patient education and self-management programs within the healthcare system to achieve this. These programs aim to empower patients through providing information and teaching skills and techniques to improve self-care and doctor-patient interaction with the ultimate goal of improving quality of life. Patient education and self-management programs have been supported through several national government initiatives and implemented within the healthcare setting. This paper describes the current position of patient education and self-management within the Australian healthcare system. It further describes a new collaboration project between an Australian and a German research team which aims at translating an assessment questionnaire used in Australia for the evaluation of self-management programs, the "Health Education Impact Questionnaire" ("heiQ"); this instrument is expected to be of significant use in the German rehabilitative system.

Background: Methotrexate is considered to have the best ratio of efficacy to toxicity of the disease modifying antirheumatic drugs. Recently it has been shown to enhance the life expectancy of patients with rheumatoid arthritis. Some 30-60% of RA patients discontinue MTX treatment within 1 year because of side-effects. In this review, the current data about supplementation with folate or folinic acid and their effect on the toxicity and efficacy of low-dose methotrexate therapy are analysed., Methods: A Medline search was performed using "folate", "folic acid", "folinic acid", "homocysteine", "methotrexate", "cardiovascular", "heart infarction" and "rheumatoid arthritis" as search terms. The relevant literature was reviewed and other papers referred to as references were explored., Conclusion: Both folate and folinic acid reduce methotrexate toxicity and the discontinuation rate, and decrease methotrexate-induced hyperhomocysteinemia. Folate is less expensive, more secure and easier to handle than folinic acid. The efficacy of methotrexate probably decreases slightly, but the benefit outweighs the risk. Folate supplementation should, therefore, be routinely prescribed to every patient taking low-dose methotrexate.

The therapeutic specialties of osteoporosis in inflammatory rheumatic diseases has gained mounting interest in the last year. The paper describes special aspects of osteoporosis in rheumatoid arthritis, ankylosing spondylitis and systemic lupus erythematodes. The problems of glucocorticoid therapy are discussed intensively with regard to the recently published recommendations for glucocorticoid-induced osteoporosis. Risk factors of osteoporosis and the therapeutic implications are demonstrated intensively as well as the modifications of the recommendations.

Anti-neutrophil cytoplasmic antibodies (ANCA) are a heterogeneous group of autoantibodies with a wide and diverse range of clinical associations. Over the past decade ANCA have been the subject of extensive investigations. In vasculitis the diagnostic utility of proteinase 3 (PR3)-ANCA and myeloperoxidase (MPO)-ANCA for Wegener's granulomatosis (WG) and microscopic polyangiitis (MPA), respectively, is now well established. Because of their significance as tools for diagnosis and prognosis of "ANCA-associated vasculitides," these autoantibodies have been analyzed extensively as markers for underlying immunopathogenic disturbances. Data regarding the detection of ANCA and their diagnostic value and role in the pathogenesis of rheumatic disorders will be discussed in this review. Growing evidence points to a pathophysiologic and diagnostic relevance of the ANCA target antigens PR3 and MPO. To date, there is mounting evidence that ANCA can have pathophysiologic effects on neutrophils, and may play a direct role in ANCA-associated vasculitides. A pathogenic model for ANCA-mediated vasculitis will be presented in this paper.

In rheumatology, besides generally acknowledged so-called "natural treatment" methods, disputed and non-suitable methods are alleged as being also "natural methods". In particular, it is the "Action for Biological Medicine" which strives against any necessity of a differentiated approach on the basis of the benefit-risk relation. In this paper, after a short introduction covering the present legal situation in Germany, examples of unconventional diagnostic and therapeutic methods are discussed. Since the alleged benefit of these methods has never been proved, they must without any exception be considered as totally unnecessary. Moreover, because of the high risk involved, some methods must be warned against. Instead, demonstrably successful psychological and behavior-therapeutic methods should be recommended, the more so, as these can assist patients in becoming independent.

This paper discusses the importance of cognitive representation and individual patterns of behavior for coping with chronic disease. Chronically ill patients differ very much in their psychic situation. Biographical and situational factors and the future perspective contribute to these interindividual differences. Diagnostic and therapeutical tools are discussed from a psychological perspective.

This paper first tries to relate the four types of immuno-pathologic reactions to certain basis-reactions of the lung. Subsequently, radiologic patterns will be correlated to these basis-reactions and will be further related to certain rheumatic diseases. It is shown that these basis-reactions cannot be clinically and radiologically distinguished from one another in all cases, and that in most cases there are combinations of several types of reaction to be found. The radiological patterns in the most important rheumatic diseases are demonstrated in an immunological arrangement. The possibilities of conventional radiological techniques and modern imaging techniques are described.

As compared to other imaging modalities, magnetic resonance imaging (MRI) is characterized by superior soft tissue contrast, multiplanar display, and lack of ionizing radiation and other hazards. Contrast media, including paramagnetic substances, (e.g., gadolinium-DTPA) are useful for further improvement of diagnostic capabilities of MRI. In this paper the results of MRI in rheumatoid arthritis and related disorders, as well as the potentials of its clinical use are discussed.

The paper takes a retrospective view back to the historical beginning of roentgenology. The development of radiology of bone and joints is high-lighted with special respect of rheumatology. Completeness was not intended regarding the size of this paper. It is shown, especially to our younger colleagues, how hard it was in the past 90 years to achieve our today-knowledge in x-ray-diagnostic. Three factors determined Roentgenology to become an indispensable method. The continuing development and improving of efficient x-ray-machines. The development and improving of investigation methods. The scientific workup of radiological signs leading to radiomorphologic features. Some milestones of technical development of conventional radiology are listed up. Also, innovations in microelectronics. Computed tomography and Magnetic Resonance are listed up. Remarks are made about costs of "big machines" and about declining knowledge in conventional radiology in young american radiologists. Recommendations are made for efficient collaboration of rheumatologists and radiologists.
