Our aim was to conduct a population-based projection to estimate the number of rheumatoid arthritis (RA) cases in Germany until 2040. Data obtained from a report published in 2017 (doi:10.20364/VA-17.08) were used for future prediction analysis. The data were originally collected by the German Central Institute for Statutory Health Insurance. We used the illness–death model to estimate future numbers of RA cases, considering nine possible scenarios based on different incidence and mortality rates. In the baseline scenario, the number of women with RA is projected to increase by 417 000 cases and men by 179 000 cases by 2040, compared with 2015. Peak numbers of cases are concentrated in the 70–80-year-old age group, particularly among women. In the most favourable scenario (scenario 2), assuming a decreasing incidence, the total number of RA cases is projected to rise by 284 000 by 2040, reflecting a 38% relative increase from 2015 to 2040. The least favourable scenario (scenario 9), assuming an increasing incidence, projects a significant burden on the healthcare system. The total number of RA cases is expected to rise by 1.16 million by 2040, marking a substantial 158% relative increase from 2015 to 2040. Our research emphasizes a discernible trend: with an ageing society, improving treatment effectiveness, and declining all-cause mortality, we anticipate a rise in the absolute numbers of RA cases in Germany in the coming years. Our models robustly support this viewpoint, underscoring impending challenges for healthcare systems. Addressing these challenges demands multifaceted interventions. [ABSTRACT FROM AUTHOR]

Background: Uncomplicated bacterial urinary tract infections (uUTIs) are commonly seen in outpatient practice. They are usually treated empirically with antibiotics. The pertinent German Clinical Practice Guideline contains recommendations on antibiotic selection, with the additional advice that the local resistance situation should be considered as well. However, up-to-date information on local resistance is often unavailable, because microbiological testing is mainly recommended for complicated UTIs. Resistance rates are often higher in recurrent uUTIs than in single episodes. In this study, we aimed to determine the resistance rates of Escherichia coli (E. coli) in patients with community-acquired uUTIs and to make these data available to the treating physicians. Methods: In a nationwide cross-sectional study in Germany (DRKS 00019059), we determined the percentages of resistance to antibiotics recommended for uUTIs (first choice: fosfomycin, nitroxoline, mecillinam, nitrofurantoin, trimethoprim; second choice: cefpodoxime, ciprofloxacin, cotrimoxazole, levofloxacin, norfloxacin, ofloxacin) over the period 2019-2021. The data were stratified by single episodes vs. recurrent UTIs (rUTIs). Results: Data from 2390 subjects were analyzed. E. coli was found in 75.4% of the samples with positive urine cultures (1082 out of 1435). The resistance rate of E. coli in single episodes (n = 725) was less than 15% for all antibiotics tested. In rUTIs (n = 357), resistance rates were also less than 15% for the most part; the only exceptions were trimethoprim (21.4%) and cotrimoxazole (19.3%). Conclusion: For single episodes of uUTI, all of the antibiotics studied can be recommended, at least as far as their resistance profiles are concerned. For recurrent UTI, all but trimethoprim and cotrimoxazole can be recommended. The second-choice antibiotics examined do not have a more favorable resistance profile than the first-choice antibiotics.

Background: Fish migration has severely been impacted by dam construction. Through the disruption of fish migration routes, freshwater fish communities have seen an incredible decline. Fishways, which have been constructed to mitigate the problem, have been shown to underperform. This is in part due to fish navigation still being largely misunderstood. Recent developments in tracking technology and modelling make it possible today to track (aquatic) animals at very fine spatial (down to one meter) and temporal (down to every second) scales. Hidden Markov models are appropriate models to analyse behavioural states at these fine scales. In this study we link fine-scale tracking data of barbel (Barbus barbus) and grayling (Thymallus thymallus) to a fine-scale hydrodynamic model. With a HMM we analyse the fish's behavioural switches to understand their movement and navigation behaviour near a barrier and fishway outflow in the Iller river in Southern Germany. Methods: Fish were tracked with acoustic telemetry as they approached a hydropower facility and were presented with a fishway. Tracking resulted in fish tracks with variable intervals between subsequent fish positions. This variability stems from both a variable interval between tag emissions and missing detections within a track. After track regularisation hidden Markov models were fitted using different parameters. The tested parameters are step length, straightness index calculated over a 3-min moving window, and straightness index calculated over a 10-min window. The best performing model (based on a selection by AIC) was then expanded by allowing flow velocity and spatial velocity gradient to affect the transition matrix between behavioural states. Results: In this study it was found that using step length to identify behavioural states with hidden Markov models underperformed when compared to models constructed using straightness index. Of the two different straightness indices assessed, the index calculated over a 10-min moving window performed better. Linking behavioural states to the ecohydraulic environment showed an effect of the spatial velocity gradient on behavioural switches. On the contrary, flow velocity did not show an effect on the behavioural transition matrix. Conclusions: We found that behavioural switches were affected by the spatial velocity gradient caused by the attraction flow coming from the fishway. Insight into fish navigation and fish reactions to the ecohydraulic environment can aid in the construction of fishways and improve overall fishway efficiencies, thereby helping to mitigate the effects migration barriers have on the aquatic ecosystem.

Background: In late 2022, health care institutions in Germany reported an unusual number of severe, invasive bacterial infections in association with a high incidence of viral respiratory infections. Methods: We analyzed routine data on invasive infections due to Haemophilus influenzae, Neisseria meningitidis, Staphylococcus aureus, Streptococcus pneumoniae, and Streptococcus pyogenes (20172023) from a voluntary, laboratory-based surveillance system involving continuously participating facilities providing diagnostic routine data that cover approximately one-third of the German population. Results: In the first quarter (Q1) of 2023, the number of invasive S. pyogenes isolates rose by 142% (n =837 vs. mean Q1/20172019=346, 95% CI [258; 434]), while the number of H. influenzae isolates rose by 90% (n =209 in Q1/2023 vs. mean Q1/20172019=110, 95% CI [79; 142]), compared to pre-pandemic seasonal peak values. The number of invasive S. pneumoniae isolates was high in two quarters (n =1732 in Q4/2022 und Q1/2023). Adults aged 55 and older and children younger than 5 years were most affected by invasive H. influenzae, S. pneumoniae, and S. pyogenes infections. N. meningitidis was most commonly found in children under age 5. Conclusion: The reason for the marked rise in invasive bacterial infections may be an increased circulation of respiratory pathogens and elevated susceptibility in the population after relaxation of the measures taken to prevent COVID-19 infection. Coinfections with respiratory viruses may have reinforced this effect. We recommend continuous surveillance, preventive measures such as raising awareness about invasive bacterial diseases, and vaccination as recommended by the German Standing Committee on Vaccinations (STIKO).

Objective: Adherence to medication has a major impact on treatment control and success especially in chronic diseases but often remains unrecognized. Besides clinical, socioeconomic, disease-related and treatment-related parameters, general and personal health beliefs, as well as perception of health, can affect adherence. Our aim was to investigate the adherence to lupus-specific medications in German lupus patients and to assess influencing factors including detrimental or beneficial effects of health perceptions and beliefs. Methods: The Lupus Erythematosus (LE) Long-Term Study (LuLa-study) is a nationwide longitudinal study among German Caucasian patients with systemic lupus erythematosus who have been assessed annually using a self-reported questionnaire since 2001. In 2013, we included questions concerning medical adherence (Morisky Medication Adherence Scale; MMAS-4), beliefs about medication prescribed (BMQ), illness perception and about the patients' health locus of control (HLC). We present a cross-sectional analysis to assess predictors of adherence using a multivariable stepwise logistic regression. Results: Five hundred and seventy-nine patients participated, 81 of whom did not take any lupus-specific medication and 40 of whom did not complete the MMAS-4 and were therefore omitted. Only 62.7% reported high adherence. Unintentional behaviour for low medical adherence exceeded the intentional behaviour by far. The use of azathioprine (OR: 1.85; 95% CI: 1.02-3.34), prednisone <7.5 mg (OR: 1.56; 95% CI: 0.97-2.49), a higher age (OR: 1.06; 95% CI: 1.03-1.08) and higher external HLC (OR: 1.15; 95% CI: 1.01-1.30) proved conducive for high adherence in our multivariable model. On the contrary, the general perception of medication being harmful or addictive (OR: 0.89; 95% CI: 0.82-0.97) was detrimental. Conclusion: A low belief that one's own health is determined by healthcare providers (external HLC) and the belief of the harmfulness of medication were independent predictors of low adherence besides age and the choice of the medical agent. The recognition of these potential obstacles in physician-patient relationships is essential to ameliorate adherence. Provision of sufficient information and education might help to reach the best possible outcome. Lupus (2018) 27, 1652-1660. [ABSTRACT FROM AUTHOR]

The article presents a report which aims to estimate the prevalence and future number of systemic lupus erythematosus (SLE) in Germany. The study screened data from the statutory health insurance in the country for SLE diagnoses and the gender- and age-specific prevalence of SLF is measured. Results showed that the gender- and age-specific prevalence of SLE will not change substantially, but the number of cases will change until 2034.

The article presents a study that evaluates the intrauterine course and the effects of tricuspid atresia detected in the fetus. The study is undertaken through a review of all tricuspid atresia cases identified prenatally between 1998 and 2006 in three referral centers in Germany. Results of the study show that tricuspid atresia were detected in 54 cases during the study period, 28 cases exhibit concordant ventriculoarterial connection of which 14 had aortic outflow obstruction.

This study aims to investigate the barriers and facilitators to guideline adherence for the print format of the German schizophrenia guideline as well as for the concept of a digital living guideline for the first time. For this purpose, the schizophrenia guideline was transferred to a digital guideline format within the web-based tool MAGICapp. An online survey was performed under participation of mental healthcare professionals (medical doctors, psychologists/psychotherapists, psychosocial therapists, caregivers) in 17 hospitals for psychiatry in Southern Germany and a professional association for German neurologists and psychiatrists. 524 participants opened the survey, 439 completed the demographic questions and commenced the content-related survey and 309 provided complete data sets. Results indicate a higher occurrence of knowledge-related barriers for the living guideline. The print version is associated with more attitude-related and external barriers. Older professionals reported more attitude-related barriers to a living guideline compared to younger professionals. Differences between professions regarding barriers were found for both formats. Various barriers exist for both guideline formats and a need for facilitators was expressed across professions. Many of the mentioned obstacles and facilitators can be more easily addressed with living guidelines. However, also living guidelines face barriers. Thus, the introduction of these new formats alone cannot lead to sustainable behavior change regarding guideline adherence. Yet, living guidelines seem to be a cornerstone to improved and tailored guideline implementation as they facilitate to keep recommendations up to date and to address the need of individual professional groups., (© 2023.

Background: Rising Lyme borreliosis incidence rates, potential for severe outcomes, and limitations in accurate and timely diagnosis for treatment initiation suggest the need for a preventive vaccine; however, no vaccine is currently available for human use. We performed two studies in adults to optimise the dose level and vaccination schedule for VLA15, an investigational Lyme borreliosis vaccine targeting outer surface protein A (OspA) serotypes 1-6, which are associated with the most common pathogenic Borrelia species in Europe and North America., Methods: Both randomised, observer-blind, placebo-controlled, multicentre phase 2 studies included participants aged 18-65 years without recent history of Lyme borreliosis or tick bites. Study one was conducted at nine clinical research and study centre sites in the USA (n=6), Germany (n=2), and Belgium (n=1); study two was conducted at five of the study one US sites. Based on a randomisation list created by an unmasked statistician for each study, participants were randomly assigned via an electronic case report form randomisation module to receive 90 μg (study one only), 135 μg, or 180 μg VLA15 or placebo by intramuscular injection at months 0, 1, and 2 (study one) or 0, 2, and 6 (study two). Study one began with a run-in phase to confirm safety, after which the Data Safety Monitoring Board recommended the removal of the 90 μg group and continuation of the study. In the study one run-in phase, randomisation was stratified by study site, whereas in the study one main phase and in study two, randomisation was stratified by study site, age group, and baseline B burgdorferi (sensu lato) serostatus. All individuals were masked, other than staff involved in randomisation, vaccine preparation or administration, or safety data monitoring. The primary endpoint for both studies was OspA-specific IgG geometric mean titres (GMTs) at 1 month after the third vaccination and was evaluated in the per-protocol population. Safety endpoints were evaluated in the safety population: all participants who received at least one vaccination. Both studies are registered at ClinicalTrials.gov (study one NCT03769194 and study two NCT03970733) and are completed., Findings: For study one, 573 participants were screened and randomly assigned to treatment groups between Dec 21, 2018, and Sept, 26, 2019. For study two, 248 participants were screened and randomly assigned between June 26 and Sept 3, 2019. In study one, 29 participants were assigned to receive 90 μg VLA15, 215 to 135 μg, 205 to 180 μg, and 124 to placebo. In study two, 97 participants were assigned to receive 135 μg VLA15, 100 to 180 μg, and 51 to placebo. At 1 month after the third vaccination (ie, month 3), OspA-specific IgG GMTs in study one ranged from 74·3 (serotype 1; 95% CI 46·4-119·0) to 267·4 units per mL (serotype 3; 194·8-367·1) for 90 μg VLA15, 101·9 (serotype 1; 87·1-119·4) to 283·2 units per mL (serotype 3; 248·2-323·1) for 135 μg, and 115·8 (serotype 1; 98·8-135·7) to 308·6 units per mL (serotype 3; 266·8-356·8) for 180 μg. In study two, ranges at 1 month after the third vaccination (ie, month 7) were 278·5 (serotype 1; 214·9-361·0) to 545·2 units per mL (serotype 2; 431·8-688·4) for 135 μg VLA15 and 274·7 (serotype 1; 209·4-360·4) to 596·8 units per mL (serotype 3; 471·9-754·8) for 180 μg. Relative to placebo, the VLA15 groups had more frequent reports of solicited local adverse events (study one: 94%, 95% CI 91-96 vs 26%, 19-34; study two: 96%, 93-98 vs 35%, 24-49 after any vaccination) and solicited systemic adverse events (study one: 69%, 65-73 vs 43%, 34-52; study two: 74%, 67-80 vs 51%, 38-64); most were mild or moderate. In study one, unsolicited adverse events were reported by 52% (48-57) of participants in the VLA15 groups and 52% (43-60) of those in the placebo groups; for study two these were 65% (58-71) and 69% (55-80), respectively. Percentages of participants reporting serious unsolicited adverse events (study one: 2%, 1-4; study two: 4%, 2-7) and adverse events of special interest (study one: 1%, 0-2; study two: 1%, 0-3) were low across all groups. A single severe, possibly related unsolicited adverse event was reported (worsening of pre-existing ventricular extrasystoles, which resolved after change of relevant concomitant medication); no related serious adverse events or deaths were reported., Interpretation: VLA15 was safe, well tolerated, and elicited robust antibody responses to all six OspA serotypes. These findings support further clinical development of VLA15 using the 180 μg dose and 0-2-6-month schedule, which was associated with the greatest immune responses., Funding: Valneva., Competing Interests: Declaration of interests NB, LW, VK, MO, NW, RH, MS, KD, SE-L, and WB are current or former employees of Valneva and may hold stock or stock options.

In pharmacoepidemiology, robust data are needed to judge the impact of drug treatment on pregnancy, pregnancy outcomes and breast-fed infants. As pregnant and breastfeeding women are usually excluded from randomised clinical trials, observational studies are required. One of those data sources are pregnancy registers specifically developed to focus on certain diseases or disease groups. The German Rhekiss register investigates pregnancies in women with chronic inflammatory rheumatic diseases (IRD). Rhekiss is a nationwide, multicentre, longitudinal study, in which women aged 18 years or older with an underlying IRD can be enrolled by a rheumatologist either when planning a pregnancy or in the first half of pregnancy. Data are collected prospectively at regular follow-up visits. Rheumatologists and patients provide information in a web-based system before conception (if enrolment was at the time of pregnancy planning), during and after pregnancy. A smartphone app is available for patients. Maternal and clinical information, general laboratory markers, treatment with antirheumatic and other drugs, adverse events, items related to course and outcome of pregnancy and the health of the child are uniformly assessed for all diseases. Individual information on the IRD includes classification criteria, diagnosis-specific laboratory parameters, clinical parameters and validated instruments to measure disease activity or damage. Furthermore, patient-reported outcome measures are captured. A total of 2013 individual patients have been enrolled in the register, and data on 1801 completed pregnancies are available. In summary, Rhekiss is a comprehensive and complex register that can answer various research questions about pregnancy in women with chronic IRDs., (© 2024 The Author(s).

Background: Clinical practice guidelines are crucial for enhancing healthcare quality and patient outcomes. Yet, their implementation remains inconsistent across various professions and disciplines. Previous findings on the implementation of the German guideline for schizophrenia (2019) revealed low adherence rates among healthcare professionals. Barriers to guideline adherence are multifaceted, influenced by individual, contextual, and guideline-related factors. This study aims to investigate the effectiveness of a digital guideline version compared to print/PDF formats in enhancing guideline adherence., Methods: A multicenter, cluster-randomized controlled trial was conducted in South Bavaria, Germany, involving psychologists and physicians. Participants were divided into two groups: implementation of the guideline using a digital online version via the MAGICapp platform and the other using the traditional print/PDF version. The study included a baseline assessment and a post-intervention assessment following a 6-month intervention phase. The primary outcome was guideline knowledge, which was assessed using a guideline knowledge questionnaire., Results: The study included 217 participants at baseline and 120 at post-intervention. Both groups showed significant improvements in guideline knowledge; however, no notable difference was found between both study groups regarding guideline knowledge at either time points. At baseline, 43.6% in the control group (CG) and 52.5% of the interventional group (IG) met the criterion. There was no significant difference in the primary outcome between the two groups at either time point (T0: Chi 2 (1)  = 1.65, p = 0.199, T1: Chi 2 (1)  = 0.34, p = 0.561). At post-intervention, both groups improved, with 58.2% in the CG and 63.5% in the IG meeting this criterion., Conclusions: While the study did not include a control group without any implementation strategy, the overall improvement in guideline knowledge following an implementation strategy, independent of the format, was confirmed. The digital guideline version, while not superior in enhancing knowledge, showed potential benefits in shared decision-making skills. However, familiarity with traditional formats and various barriers to digital application may have influenced these results. The study highlights the importance of tailored implementation strategies, especially for younger healthcare providers., Trial Registration: https://drks.de/search/de/trial/DRKS00028895., (© 2024.

Objective: In a growing list of countries, patients are granted access to their clinical notes ("open notes") as part of their online record access. Especially in the field of mental health, open notes remain controversial with some clinicians perceiving open notes as a tool for improving therapeutic outcomes by increasing patient involvement, while others fear that patients might experience psychological distress and perceived stigmatization, particularly when reading clinicians' notes. More research is needed to optimize the benefits and mitigate the risks., Methods: Using a qualitative research design, we conducted semi-structured interviews with psychiatrists practicing in Germany, to explore what conditions they believe need to be in place to ensure successful implementation of open notes in psychiatric practice as well as expected subsequent changes to their workload and treatment outcomes. Data were analyzed using thematic analysis., Results: We interviewed 18 psychiatrists; interviewees believed four key conditions needed to be in place prior to implementation of open notes including careful consideration of (1) diagnoses and symptom severity, (2) the availability of additional time for writing clinical notes and discussing them with patients, (3) available resources and system compatibility, and (4) legal and data protection aspects. As a result of introducing open notes, interviewees expected changes in documentation, treatment processes, and doctor-physician interaction. While open notes were expected to improve transparency and trust, participants anticipated negative unintended consequences including the risk of deteriorating therapeutic relationships due to note access-related misunderstandings and conflicts., Conclusion: Psychiatrists practiced in Germany where open notes have not yet been established as part of the healthcare data infrastructure. Interviewees were supportive of open notes but had some reservations. They found open notes to be generally beneficial but anticipated effects to vary depending on patient characteristics. Clear guidelines for managing access, time constraints, usability, and privacy are crucial. Open notes were perceived to increase transparency and patient involvement but were also believed to raise issues of stigmatization and conflicts., (© 2024. The Author(s).)

Purpose: Patient satisfaction with healthcare has been linked to clinical outcomes and regulatory agencies demand its regular assessment. Therefore, we aimed to investigate patient satisfaction with radiotherapy care and its determinants., Methods: This is a secondary analysis of a multicenter prospective cross-sectional study. Eligible cancer patients anonymously completed questionnaires at the end of a course of radiotherapy. The outcome variable was overall patient satisfaction with radiotherapy care measured with a 10-point Likert scaled single-item. Given patient satisfaction was defined for patients scoring ≥ 8 points. Determinants of given patient satisfaction were assessed by univariable and multivariable analyses. A p-value < 0.05 was considered statistically significant., Results: Out of 2341 eligible patients, 1075 participated (participation rate 46%). Data on patient satisfaction was provided by 1054 patients. There was a right-skewed distribution towards more patient satisfaction (mean = 8.8; SD = 1.68). Given patient satisfaction was reported by 85% (899/1054) of the patients. Univariable analyses revealed significant associations of lower patient satisfaction with tumor entity (rectal cancer), concomitant chemotherapy, inpatient care, treating center, lower income, higher costs, and lower quality of life. Rectal cancer as tumor entity, treating center, and higher quality of life remained significant determinants of patient satisfaction in a multivariable logistic regression., Conclusion: Overall patient satisfaction with radiotherapy care was high across 11 centers in Germany. Determinants of patient satisfaction were tumor entity, treating center, and quality of life. Although these data are exploratory, they may inform other centers and future efforts to maintain high levels of patient satisfaction with radiotherapy care., (© 2023. The Author(s).)

Introduction: Climate change presents a significant risk for the mental and physical health of young people. In order to identify and properly care for potential mental health impairments from extreme weather events, the relevance of these impairments must be assessed as high by the professional groups providing care for children and adolescents. This raises the question of which factors influence the individual relevance assessment of caretaking professionals?, Methods: Data was collected creating and conducting a Germany-wide online questionnaire via LimeSurvey. The questionnaire was addressed to professionals providing care for children and adolescents, in this case medical and therapeutic personnel as well as school and pedagogical personnel. Professional associations, chief physicians and school principals were contacted as multipliers and asked to forward the questionnaire to their members and staff. The data was analyzed using the R statistical software, and multiple linear regressions were performed to test the hypotheses., Results: Overall, 648 questionnaires were taken into analysis. Approximately 70% of the participants considered climate change-induced impacts on the mental health of children and adolescents due to extreme weather events as relevant. Experiencing heat, storm, heavy precipitation, flood/flooding, and/or avalanches/mudflows made a modest yet significant contribution to explaining higher relevance assessments. In contrast, there was no evidence to suggest that an urban working environment increases the relevance assessment., Conclusion: The described influence of experiencing extreme weather events should not be regarded as the sole factor leading to higher relevance ratings. A more comprehensive understanding of the factors influencing relevance assessments is necessary to address key aspects of risk communication and increase risk awareness., (© 2024. The Author(s).)

The population-based prevalence of psoriatic arthritis (PsA) is still unclear and not well described globally. The aim of this study was to conduct a population-based prevalence projection and provide long-term future estimations of PsA patients in Germany until 2050, using the illness-death model and based on historical data. We analyzed the national statutory health insurance data of 65 million population in the German Institute for Medical Documentation and Information between January 2009 and December 2012. We constructed an estimation of the PsA burden among the German population using the relevant epidemiological parameters to project the numbers of patients with PsA in Germany until 2050 under five possible scenarios by varying the incidence and mortality. The overall conservatively estimated prevalence of PsA in Germany in 2019 was 0.31% (95% CI 0.28-0.36%). Women contribute a higher prevalence than men in all five scenarios. In the assumed scenarios with increased incidence, the prevalence of PsA at 60 years of age could rise from 1% in 2019 to more than 3% in 2050 for both genders, with the increase particularly pronounced for women, reaching around 3.5%. However, in the assumed scenarios with decreasing incidence, the prevalence curve may flatten and begin a decreasing trend from 2035 to 2050 for both genders, achieving a prevalence of less than 1% in 2050. Our research is to generate assumed population-based data on PsA in Germany that can serve as a reference for public health stakeholders to prepare an optional intervention. We would expect worryingly high numbers in the coming decades if preventive strategies are not implemented. In the long term, it will be necessary to implement preventive strategies to identify predictors and treat psoriasis symptoms early in order to delay or even prevent the transition of psoriasis to PsA., (© 2023.

The implementation status of clinical guidelines is, despite their important role in connecting research with practice, frequently not satisfactory. This study aims to investigate the implementation status of the current German guideline for schizophrenia. Moreover, the attitude toward a living guideline has been explored for the first time by presenting screenshots of the German schizophrenia guideline transferred to a digital living guideline format called MAGICapp. A cross-sectional online survey was performed under the participation of 17 hospitals for psychiatry and psychosomatic medicine in Southern Germany and one professional association for German neurologists and psychiatrists. 439 participants supplied sufficient data for analysis. 309 provided complete data sets. Regarding the current guideline for schizophrenia and key recommendations, a large awareness-to-adherence gap was found. Group comparisons between different professions (caregivers, medical doctors, psychologists/psychotherapists, psychosocial therapists) detected differences in the implementation status showing higher awareness and agreement with the schizophrenia guideline and its key recommendations among medical doctors compared to psychosocial therapists and caregivers. Moreover, we detected differences in the implementation status of the guideline as a whole and its key recommendations between specialist and assistant doctors. The attitude toward an upcoming living guideline was mostly positive, especially among younger healthcare professionals. Our findings confirm an awareness-to-adherence gap, not only for the current schizophrenia guideline in general but also for its key recommendations with apparent differences between professions. Overall, our results show promising positive attitudes toward the living guideline for schizophrenia among healthcare providers, suggesting that a living guideline may be a supportive tool in everyday clinical practice., (© 2023.

Aim: This study sought to identify groups of colorectal cancer patients based upon trajectories of fatigue and examine how demographic, clinical and behavioural risk factors differentiate these groups., Method: Patients were from six cancer centres in the United States and Germany. Fatigue was measured using the fatigue subscale of the European Organization for Research and Treatment of Cancer Quality of Life Questionnaire (EORTC QLQ-C30) at five time points (baseline/enrolment and 3, 6, 12 and 24 months after diagnosis). Piecewise growth mixture models identified latent trajectories of fatigue. Logistic regression models examined differences in demographic, clinical and behavioural characteristics between fatigue trajectory groups., Results: Among 1615 participants (57% men, 86% non-Hispanic White, mean age 61 ± 13 years at diagnosis), three distinct groups were identified. In the high fatigue group (36%), fatigue significantly increased in the first 6 months after diagnosis and then showed statistically and clinically significant improvement from 6 to 24 months (P values < 0.01). Throughout the study period, average fatigue met or exceeded cutoffs for clinical significance. In the moderate (34%) and low (30%) fatigue groups, fatigue levels remained below or near population norms across the study period. Patients who were diagnosed with Stage II-IV disease and/or current smokers were more likely to be in the high fatigue than in the moderate fatigue group (P values < 0.05)., Conclusion: A large proportion of colorectal cancer patients experienced sustained fatigue after initiation of cancer treatment. Patients with high fatigue at the time of diagnosis may benefit from early supportive care., (© 2023 Association of Coloproctology of Great Britain and Ireland.)

Objectives: Various measures are used to improve the quality of stroke care. In Germany, these include concentrating treatment in specialized facilities (stroke units), mandatory quality comparisons of hospitals in some German states, and treatment according to prespecified structure and process specifications (neurological complex treatment 8-981 or 8-98b). These measures have previously only been analyzed individually and regarding short-term patient outcomes. This study analyzes these measures in combination, considering patients' comorbidities as well as stroke severity in a longitudinal perspective., Materials/methods: Analyses were based on data from 243,415 insurees of Germany's biggest health insurance (AOK) admitted to hospitals between 2007 and 2017 with cerebral infarction. Mortality risk was calculated using Cox regressions adjusted for various covariates. Kaplan-Meier analyses were differentiated by treatment site (stroke unit/external quality assurance/ Federal State Consortium of Quality Assurance Hesse - LAGQH) were performed, followed by log-rank tests and p-value adjustment. Trend analyses were performed for treatment types in combination with treatment sites., Results: All analyses showed significant advantages for patients who received Neurological Complex Treatment, especially when the treatment was performed under external quality assurance conditions and/or in stroke units. There was an increasing frequency of specialized stroke treatment., Conclusions: Quality-enhancing structures and processes are associated with a lower mortality risk after stroke. There appears to be evidence of a cascading benefit from the implementation of neurological complex treatment, external quality assurance, and ultimately, stroke units. Consecutively, care should be concentrated in hospitals that meet these specifications. However, since measures are often applied in combination, it remains unclear which specific measures are crucial for patient outcome., Competing Interests: Declaration of Competing Interest None., (Copyright © 2023 Elsevier Inc.

Purpose: Psychosocial distress is common among cancer patients in general, but those undergoing radiotherapy may face specific challenges. Therefore, we investigated the prevalence and risk factors for distress in a large national cohort., Methods: We performed a secondary analysis of a multicenter prospective cross-sectional study which surveyed cancer patients at the end of a course of radiotherapy using a patient-reported questionnaire. Distress was measured with the distress thermometer (DT), using a cut-off of ≥ 5 points for clinically significant distress. Univariate analyses and multivariate multiple regression were used to assess associations of distress with patient characteristics. A two-sided p-value < 0.05 was considered statistically significant., Results: Out of 2341 potentially eligible patients, 1075 participated in the study, of which 1042 completed the DT. The median age was 65 years and 49% (511/1042) of patients were female. The mean DT score was 5.2 (SD = 2.6). Clinically significant distress was reported by 63% (766/1042) of patients. Of the patient characteristics that were significantly associated with distress in the univariate analysis, a lower level of education, a higher degree of income loss, lower global quality of life, and a longer duration of radiotherapy in days remained significantly associated with higher distress in the multivariate analysis. Yet effect sizes of these associations were small., Conclusion: Nearly two in three cancer patients undergoing radiotherapy reported clinically significant distress in a large multicenter cohort. While screening and interventions to reduce distress should be maintained and promoted, the identified risk factors may help to raise awareness in clinical practice., Trial Registry Identifier: DRKS: German Clinical Trial Registry identifier: DRKS00028784., (© 2023.

Hintergrund: Um die Schlaganfallversorgung zu optimieren, wurden in Deutschland in den letzten Jahren verschiedene qualitätsfördernde Maßnahmen (qfM) in regional unterschiedlichem Maß eingeführt. Ob sich diese Maßnahmen über die Jahre flächendeckend etabliert haben, ist unklar., Methode: Für die strukturbezogenen Analysen der Schlaganfallversorgung in Deutschland wurden alle relevanten dokumentierten Schlaganfälle (ICD-10) aus den Qualitätsberichten (QB) deutscher Krankenhäuser und eine repräsentative Stichprobe von Krankenversicherungsdaten (AOK) im Zeitraum von 2006 (QB)/2007 (AOK) bis 2017 verwendet. Diese Informationen wurden u. a. durch Angaben zu zertifizierten Stroke Units der Deutschen Schlaganfall-Gesellschaft (DSG) und Daten zur Führung von regionalen Schlaganfall-Registern der Arbeitsgemeinschaft Deutschsprachiger Schlaganfall-Register (ADSR) ergänzt. Zur Verfolgung der Veränderungen des Versor-gungsgeschehens im deutschen Bundesgebiet wurden die Daten mit geografischen Daten (Bundesamt für Kartographie und Geodäsie) verknüpft. Es erfolgten univariate Analysen der Daten und eine Trend-Analyse der verschiedenen qfM im Jahresverlauf (Konkordanzkoeffizient nach Kendall)., Ergebnisse: Die QB Analysen zeigten einen Anstieg kodierter Schlaganfälle in Krankenhäusern mit qfM um 14-20%. In 2006 wurden 80% der Schlaganfälle (QB) in einem Krankenhaus mit min. einer qfM kodiert, in 2017 95%. Diese Entwicklungen spiegelten sich auch in den AOK-Routinedaten wider, wobei in 2007 89% und in 2017 97% der Patient:innen unter mindestens einer qfM behandelt wurden. Dabei waren in 2007 bei 55% der behandelnden Krankenhäuser qfM vorhanden, in 2017 bei 72%., Schlussfolgerung: Patient:innen werden inzwischen signifikant häufiger in Krankenhäusern mit Spezialisierung auf die Schlaganfallversorgung behandelt. Auch die verschiedenen qfM haben sich im Laufe der Jahre im gesamten Bundesgebet verbreitet, jedoch existieren noch Versorgungslücken, die geschlossen werden sollten, damit in Zukunft alle Patient:innen qualitativ hochwertig behandelt werden können., Background: In order to optimize stroke care, various quality-enhancing measures (qfM) have been introduced in Germany in recent years to varying degrees across regions, with the aim of achieving the best possible quality of care. It is unclear whether these measures have become established nationwide over the years., Method: For the structural analyses of stroke care in Germany, all relevant documented strokes (ICD-10) from the quality reports (QB) of German hospitals and a representative sample of health insurance data (AOK) for the period from 2006 (QB)/2007 (AOK) to 2017 were used. This information was supplemented by data on certified stroke units from the German Stroke Society (DSG) and data on the maintenance of regional stroke registries from the Working Group of German-Speaking Stroke Registers (ADSR), among others. To track changes in patterns of care in Germany, the data were linked with geographic data (Federal Agency for Cartography and Geodesy). Univariate analyses of the data and a trend analysis of the different qfM over the year (Kendall concordance coefficient) were performed., Results: The analyses (QB) showed an increase in coded strokes in hospitals with qfM between 14-20%. In 2006, 80% of strokes (QB) were coded in hospitals with at least one qfM and 95% in 2017. Comparing years, AOK data showed similar trends: in 2007, 89% of patients were treated in hospitals with at least one qfM and 97% in 2017. In 2007, 55% of treating hospitals had qfM and 72% in 2017., Conclusion: Meanwhile, patients are more often treated in hospitals that specialise in stroke care. In addition, the various qfM have spread across the nation over the years, but there are still gaps in care that should be addressed to ensure quality care for all patients in the future., Competing Interests: Die Autorinnen/Autoren geben an, dass kein Interessenkonflikt besteht., (Thieme.

The intracellular bacteria Anaplasma spp. and Coxiella burnetii and the tick-borne encephalitis virus (TBEV) are tick-transmitted pathogens circulating in the southern German sheep population. Knowledge of interaction among Anaplasma spp., C. burnetii and TBEV in sheep is lacking, but together they might promote and reinforce disease progression. The current study aimed to identify co-exposure of sheep to Anaplasma spp., C. burnetii and TBEV. For this purpose, 1,406 serum samples from 36 sheep flocks located in both southern German federal states, Baden-Wuerttemberg and Bavaria, were analysed by ELISAs to determine the antibody levels of the three pathogens. Inconclusive and positive results from the TBEV ELISA were additionally confirmed by a serum neutralisation assay. The proportion of sheep with antibodies against Anaplasma spp. (47.2%), C. burnetii (3.7%) and TBEV (4.7%) differed significantly. Significantly more flocks with Anaplasma spp. seropositive sheep (91.7%) were detected than flocks with antibodies against TBEV (58.3%) and C. burnetii (41.7%), but there was no significant difference between the number of flocks which contained TBEV and C. burnetii seropositive sheep. Seropositivity against at least two pathogens was detected in 4.7% of sheep from 20 flocks. Most co-exposed sheep had antibodies against Anaplasma spp./TBEV (n = 36), followed by Anaplasma spp./C. burnetii (n = 27) and Anaplasma spp./C. burnetii/TBEV (n = 2). Only one sheep showed an immune response against C. burnetii and TBEV. Flocks with sheep being positive against more than one pathogen were widely distributed throughout southern Germany. The descriptive analysis revealed no association between the antibody response of the three pathogens at animal level. Taking the flocks as a cluster variable into account, the exposure to TBEV reduced the probability of identifying C. burnetii antibodies in sheep significantly (odds ratio 0.46; 95% confidence interval 0.24-0.85), but the reason for this is unknown. The presence of Anaplasma spp. antibodies did not influence the detection of antibodies against C. burnetii and TBEV. Studies under controlled conditions are necessary to evaluate any possible adverse impact of co-exposure to tick-borne pathogens on sheep health. This can help to clarify rare disease patterns. Research in this field may also support the One Health approach due to the zoonotic potential of Anaplasma spp., C. burnetii and TBEV., (© 2023. The Author(s).)

Background: Children and adolescents are considered to be particularly vulnerable to the psychological effects of climate change, such as extreme weather events. What are the protective factors and stressors for the mental health of the young population after extreme weather events in Germany? Methods: Nine semi-structured interviews with representatives of occupational groups providing care to children, adolescents, and political stakeholders were conducted in Simbach am Inn, a German town affected by flooding in 2016. The interviews were analyzed using qualitative content analysis according to Mayring. Results: The interviews show that the parents' dealing with what they had experienced and the concern for their relatives were the most influential stressors for children and adolescents. As protective factors, they felt that conversations with familiar people and restoring a certain "normality" were particularly important. The interviewees described both, the time of the flooding, and the time after the initial state of shock had subsided, as particularly stressful. Consequently, the experts reported on children and adolescents acutely complaining of fear, helplessness, and extreme tension. Nevertheless, the demand for psychological care increased only slightly after the flooding in Simbach am Inn. Conclusion: The social environment of children and adolescents is essential for their psychological well-being after an extreme weather event. Research, especially on children and adolescents who have already been affected, must increase in order to be able to describe influencing factors even more precisely, to protect individuals from adverse mental health effects, and to identify healthcare requirements.

Quality standards (QS) are measurable constructs designed to quantify gaps in care and subsequently to improve quality of care. The Assessment of SpondyloArthritis International Society (ASAS) recently generated and published international QS for the management of patients with axial spondyloarthritis (axSpA) for the first time. The German Society of Rheumatology (DGRh) then decided to translate, review and possibly adopt these standards by a group of experts from different care settings. Against this background, national QS for the management of patients with axSpA for Germany were developed for the first time. The main focus was on feasibility and practical relevance. Ultimately, nine QS were defined with which the quality of care in Germany can and should be measured and improved., (© 2021. The Author(s).)

Despite a qualitatively and structurally good care of patients with rheumatoid arthritis (RA) in Germany, there are still potentially amendable deficits in the quality of care. For this reason, the German Society for Rheumatology (DGRh) has therefore decided to ask a group of experts including various stakeholders to develop quality standards (QS) for the care of patients with RA in order to improve the quality of care. The QS are used to determine and quantitatively measure the quality of care, subject to relevance and feasibility. The recently published NICE and ASAS standards and a systematic literature search were used as the basis for development. A total of 8 QS, now published for the first time, were approved with the intention to measure and further optimize the quality of care for patients with RA in Germany., (© 2021. The Author(s).)

Objective: The goal of living guidelines is keeping recommendations in guidelines up-to-date as new evidence becomes available. This review aims at scoping the prevalence and formal characteristics of living guidelines in the field of medicine and explore differences between formats., Methods: A selective search of living guidelines in MEDLINE via PubMed, Google Scholar and six relevant online repositories for guidelines (MAGICApp, AWMF, GIN, NICE, WHO-Iris, BIGG) was conducted. Authors and editors were contacted to receive previous non-living guideline versions. Living guidelines were subsequently analyzed according to pre-defined methodological criteria as described below (inter-comparison). Differences between living and their conventional (non-living) versions were assessed (intra-comparison)., Results: 83 living guidelines were identified and selected for further screening, out of which 26 were eligible for analysis. 61.5% were new publications (de-novo guidelines) and 38.5% updates of pre-existing guidelines. There are some concepts defining, for example, the update cycle (AWMF, maximum of 12 months) but not all living guidelines follow or refer to existing concepts. The analysis shows that living guidelines in line with the established standards for (non-living) clinical guidelines involve an evidence standard, an extensive consensus process (often in the form of a Delphi process), and the inclusion of stakeholders (patients/relatives) in the development process, despite the high frequency of updates. When comparing living and conventional guidelines with the descriptive approach changes were found in update frequency (being more frequent with living guidelines, annually at the latest) and publication format (towards more digital) and public consultation (living guidelines offered more possibilities), no substantial methodological differences were observed in the description of consensus processes, changes in number of recommendations, inclusion of patient representatives. Given the small number of comparable pairs, the results reflect a tendency in the analyzed sample., Conclusions: The definition and development of living guidelines varied. Standardization (i. e. in the form of a checklist, procedure template) is needed to assess quality of the living process., (Copyright © 2022. Published by Elsevier GmbH.)

Background: older patients are less frequently treated in stroke units (SUs). Clinicians do not seem convinced that older patients benefit from specialised treatment in SU similarly to younger patients., Objective: our study aimed to compare older patients' long-term outcomes with and without SU treatment., Methods: this study used routinely collected health data of 232,447 patients admitted to hospitals in Germany between 2007 and 2017 who were diagnosed with ischaemic stroke (ICD 10 I63). The sample included 29,885 patients aged ≥90 years. The outcomes analysed were 10-, 30- and 90-day, and 1-, 3- and 5-year mortality and the combinations of death or recurrence, inpatient treatment and increase in long-term care needs. Bivariate chi-square tests and multivariable logistic regression analyses were used, adjusting for the covariates age, sex, co-morbidity, long-term care needs before stroke and socioeconomic status of the patients' region of origin., Results: between 2007 and 2017, 57.1% of patients aged <90 years and 49.6% of those aged ≥90 years were treated in a SU. The 1-year mortality rate of ≥90-year-olds was 56.9 and 61.9% with and without SU treatment, respectively. The multivariable-adjusted risk of death in ≥90-year-olds with SU treatment was odds ratio (OR) = 0.67 (95% confidence interval [CI] = 0.62-0.73) 10 days after the initial event and OR = 0.76 (95% CI = 0.71-0.82) 3 years after stroke., Conclusions: even very old patients with stroke benefit from SU treatment in the short and long term. Therefore, SU treatment should be the norm even in older patients., (© The Author(s) 2022. Published by Oxford University Press on behalf of the British Geriatrics Society. All rights reserved.

Background: Children are a vulnerable group affected by climate change. Paediatricians are important actors in protecting children from climate change-related health risks and in identifying and treating relevant health effects. The main objectives of this study were to determine how paediatricians assess the relevance of climate change-related health impacts, through which channels paediatricians can be reached most effectively, how often climate change-specific prevention measures are implemented and how they are assessed., Methods: Between February and July 2020, an online survey was conducted among paediatricians. The cross-sectional survey was designed to gather knowledge and attitudes about the relevance of climate change, sources of information and prevention measures. All participants who answered only one question or none at all were excluded. Differences between groups were determined using one-factorial analysis of variance. Correlations were determined using Pearson's bivariate correlation analysis and tested for two-sided significance., Results: A total of 408 questionnaires were analysed. Over 95% of the respondents were paediatricians, with just under half of them working in children's hospitals and a good third in paediatric practices. According to paediatricians, climate change has a relevant impact on children's health. The most significant effects on children's health were considered to be longer and stronger pollen seasons, neophytes and neozoa, Lyme disease and TBE (tick-borne encephalitis, summer meningoencephalitis), UV radiation and air pollutants. Certified training options in professional journals and participation in lectures or workshops at relevant congresses were identified as the two preferred types of training. Especially professional journals as the most frequently used source of information could function as a suitable tool to reach as many paediatricians as possible. 76% of the paediatricians have not yet carried out any corresponding prevention activities, although information activities for parents or children were seen as being effective by 80%. Whereas the possibilities of integrating climate change-oriented prevention activities into everyday practice, were perceived less positively. The most frequent reason given was lack of time., Discussion: To satisfy this future need for knowledge, but also for offerings from paediatricians for patients and their parents, concrete further continuous education and consultancy services must be prepared. In the future, further training offers, including the consultancy services, should be integrated into profession-specific training modules, presented at congresses, and then implemented into paediatricians' daily routine., Conclusion: The results of the study illustrate that the topic "climate change and health" has a high relevance for paediatricians and that information measures for parents are considered to be effective. Although paediatricians are concerned with the topic, there is an implementation deficit. Support is needed in the form of intensifying awareness-raising projects and educational modules for paediatricians to move from knowledge to action., (Copyright © 2022. Published by Elsevier GmbH.)

In order to shorten the prognostically relevant waiting time until diagnosis and initiation of appropriate treatment in inflammatory rheumatic diseases, rheumatological centers in many regions across Germany have established and continuously developed specific early care concepts. Evaluated models from Altötting·Burghausen, Berlin Buch, Düsseldorf and Heidelberg and their developmental stages as a response to internal and external challenges are presented in this overview. The transparent publication of the developmental steps and the exchange of experiences aim at promoting new early care concepts in other regions and continuing the joint dialogue for improvement of the early detection and quality of care of inflammatory rheumatic diseases in Germany., (© 2022.

Importance: Comparability of morbidity and mortality rates after total pancreatectomy (TP) reported by different surgical centers is limited. Procedure-specific differences, such as the extent of resection, including additional vascular or multivisceral resections, are rarely acknowledged when postoperative outcomes are reported., Objectives: To evaluate postoperative outcomes after TP and categorize different types of TP based on the extent, complexity, and technical aspects of each procedure., Design, Setting, and Participants: This single-center study included a retrospective cohort of 1451 patients who had undergone TP between October 1, 2001, and December 31, 2020. Each patient was assigned to 1 of the following 4 categories that reflect increasing levels of procedure-related difficulty: standard TP (type 1), TP with venous resection (type 2), TP with multivisceral resection (type 3), and TP with arterial resection (type 4). Postoperative outcomes among the groups were compared., Main Outcomes and Measures: Categorization of different types of TP based on the procedure-related difficulty and differing postoperative outcomes., Results: Of the 1451 patients who had undergone TP and were included in the analysis, 840 were men (57.9%); median age was 64.9 (IQR, 56.7-71.7) years. A total of 676 patients (46.6%) were assigned to type 1, 296 patients (20.4%) to type 2, 314 patients (21.6%) to type 3, and 165 patients (11.4%) to type 4 TP. A gradual increase in surgical morbidity was noted by TP type (type 1: 255 [37.7%], type 2: 137 [46.3%], type 3: 178 [56.7%], and type 4: 98 [59.4%]; P < .001), as was noted for median length of hospital stay (type 1: 14 [IQR, 10-19] days, type 2: 16 [IQR, 12-23] days, type 3: 17 [IQR, 13-29] days, and type 4: 18 [IQR, 13-30] days; P < .001), and 90-day mortality (type 1: 23 [3.4%], type 2: 17 [5.7%], type 3: 29 [9.2%], and type 4: 20 [12.1%]; P < .001). In the multivariable analysis, type 3 (TP with multivisceral resection) and type 4 (TP with arterial resection) were independently associated with an increased 90-day mortality rate., Conclusions and Relevance: The findings of this study suggest there are significant differences in postoperative outcomes when the extent, complexity, and technical aspects of the procedure are considered. Classifying TP into 4 different categories may allow for better postoperative risk stratification as well as more accurate comparisons in future studies.

Background: Quality assurance for acute in-hospital care in Germany is based on compulsory comparisons between institutions, so-called external quality assurance (EQA). The effectiveness of EQA has not yet been adequately studied. The purpose of the QUASCH project, which is supported by the Innovation Fund of the Federal Joint Committee, is to investigate the association between EQA and health care outcomes, specifically with respect to stroke., Methods: The analyses were based on data from 379 825 patients insured by the AOK health insurance fund who were acutely admitted to a hospital because of stroke over the period 2007-2017. Data on 47 659 patients were derived from EQA documentation in the state of Hesse, in which stroke EQA had already been introduced in 2003; data on the remaining 332 166 patients were from other federal states, where 117 734 of these patients had been treated under EQA conditions. The association of EQA with mortality over the period of observation was analyzed by multivariate Cox regression, with the following covariates: age, sex, comorbidities, time period of occurrence, nursing care level, type of stroke, socio-economic deprivation in the region of origin, and treatment in a stroke unit., Results: Compared to treatment without EQA, mortality risk under EQA in the state of Hesse was significantly lower (hazard ratio [HR]: 0.93; 95% confidence interval: [0.92; 0.95]). The reduction in mortality risk with EQA was somewhat lower in the other federal states (HR: 0.96 [0.95; 0.97]). Treatment in a stroke unit was associated with a mortality risk that was lower still (HR: 0.86 [0.85; 0.87]). Mortality risk rose with age, comorbidities, and need for nursing care; it was lower in women and in persons whose stroke occurred in a later period., Conclusion: Quality assurance measures are associated with lower mortality risk after stroke. The concentration of care in specially qualified institutions is associated with stronger effects than EQA alone.

Objectives: This study aims to provide a comprehensive analysis of the age-dependent risk of psoriatic arthritis (PsA). For this purpose, it focuses on the varying incidences within the different age groups., Methods: The data were collected as part of the morbidity-based risk adjustment of the statutory health insurance companies in Germany. This survey recorded the International Statistical Classification of Diseases and Related Health Problems (ICD)-coded diagnoses of 65 million German citizens. Our population-based study used these raw data to calculate the prevalence of PsA in the first step. Subsequently, we employed a new approach for the estimation of the age-specific and sex-specific incidence of PsA., Results: The age-specific and sex-specific incidence of PsA showed a continuous increase with rising age until it peaked slightly before the age of 60 and declined thereafter. The maximum value was higher in women (40 per 100 000 py) than in men (30 per 100 000 py). Furthermore, the incidence rate tends to climb over the survey period., Conclusions: The data sets identified an unexpected high incidence. A meta-analysis by Scotti et al and other recent population-based studies served as a reference for the comparison. The pattern of the age-specific incidence illustrated that the risk for PsA disease shows considerable variations depending on age., Competing Interests: Competing interests: None declared., (© Author(s) (or their employer(s)) 2021.

Objective: The aim of this study was to identify factors associated with impaired work productivity and impaired daily activities in patients with systemic lupus erythematosus (SLE)., Methods: The LuLa study is a longitudinal patient-reported study. Beyond sociodemographic data, work productivity, daily activities and fatigue, several other clinical outcome parameters (e.g. mental health-related quality of life and physical functioning, disease activity, damage and pain) were surveyed with validated questionnaires. The effects of confounders on work productivity (WPAI 2) and daily activity domains (WPAI 4) were studied by multivariate regression analysis., Results: A total of 585 patients completed the questionnaire of whom 259 were employed and analysed. The median impairment in work productivity (WPAI 2) was 20% (Q1-3 0-40), and the median impairment in daily activities (WPAI 4) was 30% (Q1-3 10-50%). Multivariate regression analysis revealed that fatigue, pain, disease activity and health-related quality of life affected WPAI 2 and 4. Furthermore, we observed distinct synergistic effects of fatigue, disease activity and pain on both work productivity and daily activities: a higher impact of fatigue was associated with the reported extent of pain or disease activity., Conclusion: In employed patients with SLE, impaired work productivity and impaired daily activities were frequently reported. Fatigue, pain, disease activity and health-related quality of life demonstrated a detrimental impact, with a synergistic effect of fatigue, disease activity and pain. Hence, both optimized pain management and targeted immunomodulatory therapy are important for preserving active participation in life among patients with fatigue.

Importance: The natural history of intraductal papillary mucinous neoplasms (IPMNs) remains uncertain. The inconsistencies among published guidelines preclude accurate decision-making. The outcomes and potential risks of a conservative watch-and-wait approach vs a surgical approach must be compared., Objective: To provide an overview of the surgical management of IPMNs, focusing on the time of resection., Design, Setting, and Participants: This cohort study was conducted in a single referral center; all patients with pathologically proven IPMN who received a pancreatic resection at the institution between October 2001 and December 2019 were analyzed. Preoperatively obtained images and the medical history were scrutinized for signs of progression and/or malignant features. The timeliness of resection was stratified into too early (adenoma and low-grade dysplasia), timely (intermediate-grade dysplasia and in situ carcinoma), and too late (invasive cancer). The perioperative characteristics and outcomes were compared between these groups., Exposures: Timeliness of resection according to the final pathological findings., Main Outcomes and Measures: The risk of malignant transformation at the final pathology., Results: Of 1439 patients, 438 (30.4%) were assigned to the too early group, 504 (35.1%) to the timely group, and 497 (34.5%) to the too late group. Radiological criteria for malignant conditions were detected in 53 of 382 patients (13.9%), 149 of 432 patients (34.5%), and 341 of 385 patients (88.6%) in the too early, timely, and too late groups, respectively (P < .001). Patients in the too early group underwent more parenchyma-sparing resections (too early group, 123 of 438 [28.1%]; timely group, 40 of 504 [7.9%]; too late group, 5 of 497 [1.0%]; P < .001), while morbidity (too early group, 112 of 438 [25.6%]; timely group, 117 of 504 [23.2%]; too late group, 158 of 497 [31.8%]; P = .002) and mortality (too early group, 4 patients [0.9%]; timely, 4 [0.8%]; too late, 13 [2.6%]; P = .03) were highest in the too late group. Of the 497 patients in the too late group, 124 (24.9%) had a previous history of watch-and-wait care., Conclusions and Relevance: Until the biology and progression patterns of IPMN are clarified and accurate guidelines established, a watch-and-wait policy should be applied with caution, especially in IPMN bearing a main-duct component. One-third of IPMNs reach the cancer stage before resection. At specialized referral centers, the risks of surgical morbidity and mortality are justifiable.

Objective: The severe acute respiratory syndrome coronavirus-2 (SARS-CoV-2) pandemic has created hitherto unknown challenges for healthcare systems and patient care. This study aimed to analyze its influence on patient care and healthcare management in oral and maxillofacial surgery (OMFS) in Germany., Materials and Methods: A nationwide survey of the German Association of Oral and Maxillofacial Surgery was performed. Individual questionnaires containing 10 questions for university as well as non-university hospitals and 15 questions for private practices (PPs) for OMFS were created to collect data for patient numbers and surgical procedures conducted, usage of personal protection equipment (PPE), SARS-CoV-2 tests, and economic aspects., Results: Fifty-four hospitals and 240 PPs participated in the study. The reduction in ward capacities and number of surgical procedures ranged from 17 to 78%. PPE consisted of standard surgical masks (58% hospitals, 64% PPs) and FFP2/N95/KN95 respirators (45% hospitals, 48% PPs). Preoperative SARS-CoV-2 tests were more frequently performed in hospitals (34% vs 2%). At PPs, turnover for medical and dental procedures billed to the public insurance had reduced to 58.81% and 62.43%, respectively, of the corresponding values for 2019, and 58.75% of the PPs had applied for short-time allowances., Conclusion: With the exception of some elective procedures, primary patient care in OMFS has been assured during the pandemic. However, the immense economic burden on hospitals and PPs cannot be conclusively assessed at this point., Clinical Relevance: For OMFS, the German healthcare system has shown the ability to adapt to emergency situations such as the SARS-CoV-2 pandemic. Adequate surgical capacities in OMFS are necessary even during pandemics.

Despite promising candidates for new therapeutic options in the treatment of systemic lupus erythematosus (SLE), many clinical trials have failed in the past few years. The disappointing results have been at least partly be attributed to trial designs. With the aim of stimulating new developments in SLE trial design, an international open space meeting was held on occasion of the European Lupus Meeting 2018 in Duesseldorf, Germany about 'What are the topics you care about for making trials in lupus more effective?'. The Open Space is a participant-driven technology, where the discussion topics and schedule are selected during the meeting by all participants and discussion rounds are led by the people attending encouraging active contributions. Eleven topics were selected for further discussion, of which 6 were voted to be more intensively discussed in two consecutive rounds. Major topics were the optimal handling of glucocorticoids in clinical trials, the improvement of outcome measures, reducing or controlling the placebo response and the identification of biomarkers and stratification parameters. Further, the importance of local and international networks was emphasised. By networking, collaborations are facilitated, patient recruitment is more efficient and treatment can be harmonised thus lead to more successful SLE trials. Further discussions are needed to substantiate the results and develop new trial designs., Competing Interests: Competing interests: None declared., (© Author(s) (or their employer(s)) 2021.

The collection of data on SARS-CoV‑2 tests is central to the assessment of the infection rate in the context of the COVID-19 pandemic. At the Robert Koch Institute (RKI), data collected from various laboratory data recording systems are consolidated. First, this article aims to exemplify significant aspects regarding test procedures. Subsequently the different systems for recording laboratory tests are described and test numbers from the RKI test laboratory query and the laboratory-based SARS-CoV‑2 surveillance as well as accounting data from the Association of Statutory Health Insurance Physicians for SARS-CoV‑2 laboratory tests are shown.Early in the pandemic, the RKI test laboratory query and the laboratory-based SARS-CoV‑2 surveillance became available and able to evaluate data on performed tests and test capacities. By recording the positive and negative test results, statements about the total number of tests and the proportion of positive test rates can be made. While the aggregate test numbers are largely representative nationwide, they are not always representative at the state and district level. The billing data of the Association of Statutory Health Insurance Physicians can complement the laboratory data afterwards. In addition, it can provide a retrospective assessment of the total number of SARS-CoV‑2 numbers in Germany, because the services provided by statutory health insurers (around 85% of the population in Germany) are included. The various laboratory data recording systems complement one another and the evaluations flow into the recommended measures for the pandemic response.

Objective: Despite increased physician's awareness and improved diagnostic and serological testing in the recent years, the interval between the initial symptoms and the diagnosis of Systemic lupus erythematosus (SLE) is still very long. Our aim was to study this delay and its association to the outcome of the disease., Methods: Information on demographics, onset of first symptoms, first physicians visit and time of diagnosis was assessed by self-reported questionnaires among SLE patients in Germany (LuLa cohort, n = 585) in the year 2012. Disease activity (Systemic Lupus Activity Questionnaire; SLAQ), disease related damage (Brief Index of Lupus Damage; BILD), health related quality of life (Short Form 12) and fatigue (FSS) were chosen as proxies for outcome. Linear regression analysis was used to analyze the association of the delay in diagnosis to the outcome, adjusted for age, disease duration and sex., Results: Mean duration between the onset of symptoms and the diagnosis of SLE was 47 months (SD 73). The longer the time to diagnosis, the higher the disease activity (β = 0.199, p < 0.0001), the disease-related damage (β = 0.137, p = 0.002) and fatigue (β 0.145, p = 0.003) and the lower the health-related quality of life (physical β = -0.136, p = 0.004, mental β = -0.143, p = 0.004)., Conclusion: In systemic lupus erythematosus, longer time to diagnosis was associated with worse outcome. Concepts in care with the intention to shorten the time to diagnosis are needed to improve the long-term outcome of the disease.

Background: In the era of personalized medicine, cancer care is subject to major changes and innovations. It is unclear, however, to what extent implementation of such innovations and their impact on patient outcomes differ by health insurance type. This study compared provision of treatment and survival outcomes among patients with colorectal cancer (CRC) who had statutory health insurance (SHI) versus private health insurance (PHI) in Germany., Methods: We analyzed patterns of CRC treatment (surgery, chemotherapy/radiotherapy, and targeted therapy) and survival in a large cohort of patients who were diagnosed with CRC in 2003 through 2014 and were observed for an average of 6 years. Associations of type of health insurance with treatment administration and with overall, CRC-specific, and recurrence-free survival were investigated using multivariable logistic and Cox proportional hazards models, respectively., Results: Of 3,977 patients with CRC, 427 (11%) had PHI. Although type of health insurance was not associated with treatment administration in patients with stage I-III disease, those with stage IV disease with PHI more often received targeted therapy (65% vs 40%; odds ratio, 2.43; 95% CI, 1.20-4.91), with differences decreasing over time because of catch-up of uptake rates in patients with SHI. Median overall survival was longer in patients with PHI than in those with SHI (137.0 vs 114.9 months; P=.010), but survival advantages were explained to a large extent by differences in sociodemographic factors. In patients with stage IV disease, survival advantages of PHI were nonsignificant and were restricted to the early years after diagnosis., Conclusions: We observed major differences in uptake of targeted therapy between patients with PHI and those with SHI but no differences in patient survival after adjusting for relevant sociodemographic, clinical, and tumor characteristics. Further studies are needed on factors associated with the uptake of therapeutic innovations and their impact on patient survival by health insurance type.

In September 2019 the Ministry of Labor, Health and Welfare (MAGS) of North-Rhine/Westphalia (NRW) published an expert report on hospital planning. In this report a fundamental reform of hospital planning was recommended, in that a requirements planning should be carried out in the future on the basis of a detailed designation of disciplines and organizational groups. At the request of the MAGS NRW, the German Society for Rheumatology (DGRh) with the support of the Association of Rheumatological Acute Clinics (VRA) has also commented on this issue.

For several years video consultations have been regarded as a new form of medical healthcare infrastructure, in addition to personal doctor-patient contacts and have also been partly promoted. The COVID-19 pandemic brought unexpected topicality and attention to the use of video consultations. The National Association of Statutory Health Insurance Physicians (Kassenärztliche Bundesvereinigung) decided on special regulations in the context of the COVID-19 pandemic, which reduce previous obstacles to the use of telemedicine and video consultations (and also partly of conventional telephony). The present statement of the German Society of Rheumatology (DGRh) on the use of video consultations is intended to give an overview of in which form and with which limitations video consultations can be used in rheumatology in Germany. It sketches an outlook on how video consultations can undertake which functions in rheumatological care in the future.

Systemic disease demands systemic thinkers. In this mission statement we define rheumatology, describe the role of the German Society of Rheumatology and the rheumatologist's spirit to their discipline. Rheumatologists are dedicated to improving the quality of life of their acute, chronic, and rehabilitative patients on the basis of up to date evidence and strong physician-patient relations. We think, act and interact systemically, scientifically, consistently, transparently, reliably, inclusively, innovatively and enthusiastically.

Oxidative stress has been implicated in the initiation of several cancers, including colorectal cancer (CRC). Whether it also plays a role in CRC prognosis is unclear. We assessed the associations of two oxidative stress biomarkers (Diacron's reactive oxygen metabolites [d-ROMs] and total thiol level [TTL]) with CRC prognosis. CRC patients who were diagnosed in 2003 to 2012 and recruited into a population-based study in Germany (n = 3361) were followed for up to 6 years. Hazard ratios (HRs) and 95% confidence intervals (95% CIs) for the associations of d-ROMs and TTL (measured from blood samples collected shortly after CRC diagnosis) with overall survival (OS) and disease-specific survival (DSS) were estimated using multivariable Cox regression. Particularly pronounced associations of higher d-ROMs with lower survival were observed in stage IV patients, with patients in the highest (vs lowest) tertile having much lower OS (HR = 1.52, 95% CI = 1.14-2.04) and DSS (HR = 1.61, 95% CI = 1.20-2.17). For TTL, strong inverse associations of TTL with mortality were observed within all stages. In patients of all stages, those in the highest (vs lowest) quintile had substantially higher OS (HR = 0.48, 95% CI = 0.38-0.62) and DSS (HR = 0.52, 95% CI = 0.39-0.69). The addition of these biomarkers to models that included age, sex, tumor stage and subsite significantly improved the prediction of CRC prognosis. The observed strong associations of higher d-ROMs and lower TTL levels with poorer prognosis even in stage IV patients suggest that oxidative stress contributes significantly to premature mortality in CRC patients and demonstrate a large potential of these biomarkers in enhancing the prediction of CRC prognosis beyond tumor stage., (© 2020 The Authors.

Background: Gastric cancer is one of the most frequent malignancies worldwide. Angiogenic growth factors play a crucial role in mediating the crosstalk between cancer cells and the surrounding microenvironment. In this exploratory study, we investigate the impact of angiogenic proteins within the tumor cell or stroma compartment on survival of patients with gastric cancer., Materials and Methods: In 29 patients, tumor and stromal compartments were separated using laser capture microdissection. Angiogenic protein expression was measured using a bead-based immunoassay and correlated with tumor stage and overall survival., Results: Overall survival was significantly shorter in patients with a high stroma concentration of vascular endothelial growth factor (VEGF)-A (23.5 (±17.6) versus 33.6 (±21.0) mo; P = 0.009) and stem cell factor (22.2 (±18.5) versus 33.6 (±21.8) mo; P = 0.01) compared with patients with a low stroma concentration. High stromal VEGF-D showed a trend toward worse survival (26.8 (±22.0) versus 37.2 (±19.0) mo; P = 0.09). We did not observe any significant correlation between tumor-specific expression of angiogenic cytokines and survival., Conclusions: This translational study highlights the difference in clinical impact between tumor and stromal expression of angiogenic proteins. Compartment-specific concentrations of VEGF-A and stem cell factor affect the clinical prognosis and help to identify the best therapy for patients with gastric cancer., (Copyright © 2020 Elsevier Inc.

To determine associations between physical activity (PA), sedentary behavior (SB), and oxidative stress in colorectal cancer patients, ColoCare Study participants in Germany wore an accelerometer 6 and/or 12 months after surgery. Spearman partial correlations were used to assess associations between PA and urinary concentrations of oxidized guanine, a validated marker of oxidative stress. There were no significant associations between PA or SB and oxidized guanine in n = 76 measurements (ng/mg creatinine; r = 0.03, p = 0.76 for PA, r = -0.05, p = 0.69 for SB). Novelty Objectively measured PA was not associated with a marker of oxidative stress in colorectal cancer patients.

A few days after the SARS-CoV-2 infection was declared a pandemic, the German Society for Rheumatology (DGRh) compiled first recommendations for the care of patients with inflammatory rheumatic diseases (IRD). These first recommendations were based on an expert consensus and were largely non-evidence-based. Now that the first scientific data from registers, cross-sectional studies, case reports and case series are available, the present update is intended to update the previous recommendations and to add new findings. The current recommendations are based on a literature search of publications available up to 15 June 2020 and address preventive measures (such as hygiene measures or vaccinations) and the use of immunomodulatory/immunosuppressive drugs. An important goal of the current recommendations is also to prevent harm to patients with IRD through unjustified restriction of care. The DGRh will continue to update its recommendations in the case of new aspects and will publish them as well as further information on the COVID-19 pandemic on its homepage ( www.dgrh.de ) in an ongoing process.

Digitalization in the healthcare system is a great challenge for rheumatology as for other medical disciplines. The German Society for Rheumatology (DGRh) wants to actively participate in this process and benefit from it. By founding the commission on digital rheumatology, the DGRh has created a committee that deals with the associated tasks, advises the DGRh on questions and positions associated with digital health. For the DGRh, this affects the most diverse areas of digitalization in medicine and rheumatology. This position paper presents the topics and developments currently handled by the commission and the tasks identified.

Objective: To assess the diagnostic potential of IgG antibodies to citrullinated and corresponding native autoantigens in early arthritis., Methods: IgG autoantibodies to 390 distinct unmodified and corresponding in vitro citrullinated recombinant proteins were measured by a multiplex assay in baseline blood samples from a German multicenter national cohort of 411 early arthritis patients (56.5 ± 14.6 years, 62.8% female). The cohort was randomly split into a training cohort (n = 329, 28.6% ACPA positive) and a validation cohort (n = 82, 32.9% ACPA pos.). The diagnostic properties of candidate antibodies to predict a subsequent diagnosis of rheumatoid arthritis (RA) as opposed to a non-RA diagnosis were assessed by receiver operating characteristics analysis and generalized linear modeling (GLM) with Bonferroni correction in comparison to clinically determined IgM rheumatoid factor (RF) and citrullinated peptide antibody (ACPA) status., Results: Of 411 patients, 309 (75.2%) were classified as RA. Detection rates of antibody responses to citrullinated and uncitrullinated forms of the proteins were weakly correlated (Spearman's r = 0.13 (95% CI 0.029-0.22), p = 0.01). The concentration of 34 autoantibodies (32 to citrullinated and 2 to uncitrullinated antigens) was increased at least 2-fold in RA patients and further assessed. In the training cohort, a significant association of citrullinated "transformer 2 beta homolog" (cTRA2B)-IgG with RA was observed (OR 5.3 × 10 3 , 95% CI 0.8 × 10 3 -3.0 × 10 6 , p = 0.047). Sensitivity and specificity of cTRA2B-IgG (51.0%/82.9%) were comparable to RF (30.8%/91.6%) or ACPA (32.1%/94.7%). Similar results were obtained in the validation cohort. The addition of cTRA2B-IgG to ACPA improved the diagnostic performance over ACPA alone (p = 0.026 by likelihood ratio test)., Conclusions: cTRA2B-IgG has the potential to improve RA diagnosis in conjunction with RF and ACPA in early arthritis.
