[Reference evaluations for estimating prevalence, incidence, and mortality of public health relevant diseases based on routine data]. / Referenzauswertungen für die Schätzung von Prävalenz, Inzidenz und Mortalität Public-Health-relevanter Erkrankungen auf Basis von Routinedaten.

The routine data of all statutorily insured persons according to the Data Transparency Regulation (DaTraV data) represent a promising data source for the recurrent and timely surveillance of non-communicable diseases (NCDs) in Germany. Thereby, it has become apparent that there is a high demand for reference evaluations that enable quick and regularly repeatable analyses on important NCDs. Against this background, ReFern-01 was initiated, a joint project of the Robert Koch Institute (RKI) and the Federal Institute for Drugs and Medical Devices (BfArM). In collaboration with experts from the field of secondary data analysis and healthcare research, reference evaluations for estimating prevalence, incidence, and mortality for important public health-relevant diseases were developed. First, 11 central NCDs were selected by means of an online survey, and initial case definitions were created in conjunction with a literature review. These were then discussed and agreed upon in a virtual workshop. The created reference evaluations (analysis scripts) allow a standardized estimation of the mentioned epidemiological figures, which are comparable over time and regionally. In addition to providing the results, the scripts will be available at the BfArM for further analysis. Provided that remote access to the analysis of the DaTraV data is available in the future, the results of the ReFern project can strengthen the surveillance of NCDs and support public health actors, for example, in the planning and implementation of health promotion and prevention measures at the federal, state, county, and local levels.

Psychometric properties of a nationwide survey for adults with and without diabetes: the "disease knowledge and information needs - diabetes mellitus (2017)" survey.

BACKGROUND: In order to close existing information gaps on diabetes-related health perceptions, diabetes knowledge, and information-seeking behaviors among adults in Germany, a representative population-based survey targeting the German-speaking population 18 years and older with and without diabetes was conducted. The aim of the present work was to analyze the psychometric properties of the multi-item scales, applied in the survey in order to provide guidance for decisions on the use of these measurements for future research. METHODS: Based on data from participants who completed the final survey (N = 1479 with known diabetes; N = 2327 without known diabetes) reliability and unidimensionality of multi-item scales were tested using Cronbach's Alpha and confirmatory factor analysis (CFA). RESULTS: Psychometric properties and model fit varied across scales. Cronbach's alpha values ranged from very good to unacceptable. Model fit indices suggested evidence of a single underlying factor in some but not all scales. Adequate reliability and at least mediocre model fit were found for diabetes distress and patient-provider-relationship in people with diabetes and for perceived level of information in individuals without diabetes. Scales revealing inacceptable reliability values or not suggesting unidimensionality were e.g. diabetes-related stigmatization in both individuals with and without diabetes, self-efficacy in individuals with diabetes, and perceived personal control in those without diabetes. CONCLUSION: Based on results of the current study, some of the scales applied in the survey can be recommended for present and future analyses of the survey data and for future surveys (e.g. diabetes distress, patient-provider-relationship in people with diabetes). Other scales should be interpreted and used with caution (e.g. depressive symptoms in people with diabetes) while others should be reformulated, interpreted only as single items, or need further investigation (e.g. diabetes-related stigmatization in people with and without diabetes). Findings provide researchers the opportunity to evaluate diabetes-specific scales in population-based studies of adults with and without diabetes.

Serology- and PCR-based cumulative incidence of SARS-CoV-2 infection in adults in a successfully contained early hotspot (CoMoLo study), Germany, May to June 2020.

Three months after a coronavirus disease (COVID-19) outbreak in Kupferzell, Germany, a population-based study (n = 2,203) found no RT-PCR-positives. IgG-ELISA seropositivity with positive virus neutralisation tests was 7.7% (95% confidence interval (CI): 6.5-9.1) and 4.3% with negative neutralisation tests. We estimate 12.0% (95% CI: 10.4-14.0%) infected adults (24.5% asymptomatic), six times more than notified. Full hotspot containment confirms the effectiveness of prompt protection measures. However, 88% naïve adults are still at high COVID-19 risk.

[Federal health reporting at the Robert Koch Institute-status quo and current developments]. / Gesundheitsberichterstattung des Bundes am Robert Koch-Institut ­ Status quo und aktuelle Entwicklungen.

Health reporting as an integral part of public health plays an important role in the development of strategies and concepts that aim to improve the health of all population groups. This article provides an overview of the definition and tasks of federal health reporting and describes important health reporting components in their current form. The publication format of the Journal of Health Monitoring, which was developed for different user groups of health monitoring, is presented. Examples of the uses and effects of health reporting are also presented. Health reporting is designed as a flexible system: changes in databases as well as forms of communication are taken into account in the further development of health reporting.The further development of health reporting requires close interdisciplinary cooperation between different actors in order to integrate current research results from various scientific disciplines into the processes of health reporting, as well as to further expand the scope and impact of health reporting. In addition, to further develop health reporting on a scientific level, the expansion of participatory elements and a stronger internationalization will be important future tasks.

[Prevalence and incidence of documented diabetes based on health claims data-reference analysis for diabetes surveillance in Germany]. / Prävalenz und Inzidenz des dokumentierten Diabetes mellitus ­ Referenzauswertung für die Diabetes-Surveillance auf Basis von Daten aller gesetzlich Krankenversicherten.

BACKGROUND: The prevalence and incidence of documented diabetes are two essential indicators intended to be reported on a periodic basis within the framework of diabetes surveillance in Germany. METHODOLOGY: Data provided based on the Data Transparency Act were analyzed. The data contain information on outpatient and inpatient care for all approximately 70 million persons with statutory health insurance. The case definition for the prevalence of documented diabetes comprises a confirmed outpatient diagnosis in at least two quarters of a year or an inpatient diagnosis in at least one quarter of a year in accordance with ICD-10 codes E10.- to E14.-. The incidence was calculated based on the same definition and with one year of diagnosis-free lead time. RESULTS: In 2011, a prevalence of 9.7% (women: 9.4%, men: 10.1%) was observed for persons with statutory health insurance. There are considerable differences in prevalence between the federal states and the maximum gap is 7.1 percentage points (age standardized: 4.0 percentage points). Type 2 and type 1 diabetes show a documented prevalence of 7.5% and 0.28%, respectively. Unspecified diabetes is documented relatively frequently with 1.9%. In 0.21% of persons, the diagnosis diabetes is documented via one inpatient secondary diagnosis. In addition, 0.17% of people without documented diabetes have at least one prescription of an antidiabetic drug. In 2012, 565,040 insured persons were newly diagnosed with diabetes; this corresponds to 1.0% of the insured persons (women: 1.0%, men: 1.1%). DISCUSSION: The developed reference analysis is suitable for reporting the prevalence and incidence of documented diabetes within the framework of diabetes surveillance. The differentiation of diabetes types is difficult due to coding practice.

[Estimating prevalent microvascular complications of diabetes mellitus in Germany. Analysis of statutory health insurance data in 2012 and 2013]. / Einschätzungen zur Prävalenz mikrovaskulärer Folgeerkrankungen bei Diabetes mellitus in Deutschland. Analyse von Versichertendaten aller gesetzlichen Krankenkassen für die Jahre 2012 und 2013.

BACKGROUND: Data sources for the systematic and ongoing analysis of prevalence of microvascular complications of diabetes mellitus are limited in Germany. For the first time, we estimated the complications prevalence based on claims data of all statutory health insurance (SHI) providers according to the Data Transparency Act. METHODS: Health claims data of the reporting years 2012 and 2013 were analyzed. The reference population was identified as insured persons with a diabetes diagnosis according to the international classification of disease. Diabetes was defined as documentation of at least two confirmed diabetes diagnoses in an outpatient setting or one diagnosis in an inpatient setting (ICD codes E10-E14). Complications were defined based on the following ICD codes: nephropathy (N08.3), retinopathy (H36.0), polyneuropathy (G63.2), diabetic foot syndrome (DFS; E10-14.74, E10-14.75), chronic kidney disease (N18.-), and treatment with dialysis (Z49.1, Z49.2, Z99.2). Results were compared to prevalence estimates based on routine data and registries in Germany and abroad. RESULTS: In 2013, diabetes was documented for 6.6 million persons with SHI (2012: 6.5 million). In 2013, chronic kidney disease (15.0%) was the most frequent complication, followed by diabetic polyneuropathy (13.5%), nephropathy (7.6%), retinopathy (7.0%), DFS (6.1%), and treatment with dialysis (0.56%). While results for diabetic retinopathy, nephropathy, and polyneuropathy are lower than prevalence estimates from other type 2 diabetes studies, they are comparable for chronic kidney disease, treatment with dialysis, and DFS. CONCLUSION: Continuous analysis of health claims data is highly valuable for the diabetes surveillance. However, detailed analyses are required for verification and harmonization of case definitions and documentation practice.

[Health reporting as part of public health surveillance: the example of diabetes]. / Gesundheitsberichterstattung im Rahmen von Public Health Surveillance: Das Beispiel Diabetes.

The continuous collection and analysis of health data on relevant diseases (surveillance) is at the core of public health. The surveillance enables the implementation of measures to protect the populations' health. Therefore, relevant information needs to be provided in a timely and target-group-specific manner to the respective stakeholders.A dissemination strategy supports the effective communication of results and considers three key questions: (1) "What content is relevant to the surveillance?", (2) "Who requires which information?" and (3) "How are the results disseminated to the target audience?" In this context, digitalisation allows for novel possibilities in the design of publication formats.Since 2015, diabetes surveillance has been established at the Robert Koch Institute. Within a structured process of consensus, we defined four fields of action relevant for health policy including 40 indicators. Thereafter, we developed the first publication formats in collaboration with the scientific advisory board of the project that reflected novel possibilities offered by digitalisation. In addition to articles in scientific journals, the essential formats of the first project phase comprise the report "Diabetes in Germany" and a website including interactive visualisations of results. Additional posts on Twitter and YouTube are used to increase coverage.In addition to the further development of the indicator set, the focus of the next project phase is the advancement of the dissemination towards user- and action-oriented reporting. In close exchange with the scientific advisory board, we aim to explore the requirements of the target audience and reflect them in the design of further publication formats.

[Is There an Association Between DMP Enrollment and Disability Pension in Rehabilitants With Type 2 Diabetes?] / Besteht bei Rehabilitanden mit Typ-2-Diabetes ein Zusammenhang zwischen DMP-Einschreibung und Bezug einer Erwerbsminderungsrente?

Efficacy of treatment of working-age patients with diabetes mellitus can be increased by rehabilitative measures. This treatment option is explicitly mentioned in the guidelines of the disease management program (DMP) for type 2 diabetes (T2D). With research data from the pension insurance fund, it is shown that for rehabilitation patients with T2D and DMP enrolment, the chance of disability pension is 23% lower than without DMP enrolment, irrespective of relevant covariates.

[Diabetes Mellitus in the Medical Rehabilitation - Use of Rehabilitation Services During 2006-2013]. / Diabetes Mellitus in der medizinischen Rehabilitation ­ Inanspruchnahme rehabilitativer Maßnahmen im Zeitraum 2006­2013.

BACKGROUND AND AIMS: Over the last years the prevalence of diabetes mellitus (DM) has risen. Due to the disease pattern an increasing importance of rehabilitation services is assumed as well. This article contributs to the debate by analyising the use of medical rehabilitations from 2006 to 2013. METHODS: The secondary data analysis is based on a scientific use file. DM is defined according to ICD-10 (E10-E14). The trends stratified by age and gender are displayed crude and standardized per 100.000. The use will be correlated with the population-based prevalence on the level of federal states. RESULTS: The standardized use rose from 2006 to 2013 in men from 170 to 204.4 and woman from 99 to 123.6 per 100.000. While it declined for people under 60 years old, it rose by about 80% in the age group of the 60-64 year-olds. The use correlated positively (r=0.64) with the population-based prevalence. CONCLUSION: As a result of increasingly late retierment, the importance of rehabilitation services in people with DM incesases.

[Environmental burden of disease in Germany]. / Umweltbedingte Krankheitslasten in Deutschland.

BACKGROUND: Environmental risk factors can have a substantial impact on population health. With the environmental burden of disease (EBD) approach, the health losses attributable to environmental risk factors can be quantified using disability-adjusted life years (DALY). OBJECTIVES: The aim of this article is to present and discuss available EBD estimates with a focus on Germany. MATERIALS: Using current EBD studies, the share of the burden of disease attributable to environmental risk factors globally and DALYs for Germany are presented. Ambient particulate matter (PM), water-related risks and environmental noise are used as examples to emphasize the importance of availability and quality of input data for burden of disease assessments. RESULTS: The share of the global burden of disease attributable to environmental risk factors varies according to the available studies and lies between 13 and 22%. For Germany, EBD estimates are available for 12 environmental risk factors. Most estimates are available for particulate matter in ambient air, however, the estimated burden differs greatly. Nonetheless, according to current knowledge, particulate matter pollution is the environmental risk factor with the highest burden of disease in Germany. CONCLUSIONS: Differences in the estimated burden of disease for the considered risk factors are due to varying underlying assumptions, e. g. for life expectancy or counterfactual value and the input data used.

BURDEN 2020-Burden of disease in Germany at the national and regional level.

BACKGROUND: Evidence-based policy measures need non-interest-guided information about the health status of a population and the diseases that affect the population the most. In such cases, a national burden of disease study can provide reliable insights at the regional level. AIM: This article presents the potential of the BURDEN 2020 project and its expected outcome for Germany at the national and regional level. METHODS: The BURDEN 2020 project uses several indicators including years of life lost (YLL) to cover the impact of mortality and years lived with disability (YLD) to cover morbidity. The sum of both is the measure of population health called disability adjusted life years (DALY). RESULTS: The study ranks individual diseases and risk factors based on their impact on population health. The burden of disease approach is assumed to be sensitive to subnational differences and may generate immediate benefits for regional planning. The BURDEN 2020 study will pilot a national burden of disease study for Germany that will later be transformed into a continuous data processing and visualization tool. This is done by using, modifying and supplementing the methodology employed by the Global Burden of Disease (GBD) study to better fit the needs of health policy in Germany. This study is aimed at calculating the disease burden for up to 17 preselected diseases. Furthermore, the estimates of burden of disease are attributed to a selected set of risk factors. CONCLUSION: The Burden 2020 study will provide the results of a new, health-related data processing system to the public. This includes a noninterest-guided presentation of the burden of disease (DALY) in Germany at the national and regional level.

National public health system responses to diabetes and other important noncommunicable diseases : Background, goals, and results of an international workshop at the Robert Koch Institute.

Diabetes mellitus and other noncommunicable diseases (NCDs) represent an emerging global public health challenge. In Germany, about 6.7 million adults are affected by diabetes according to national health surveys, including 1.3 million with undiagnosed diabetes. Complications of diabetes result in an increasing burden for individuals and society as well as enormous costs for the health care system. In response, the Federal Ministry of Health commissioned the Robert Koch Institute (RKI) to implement a diabetes surveillance system and the Federal Center for Health Education (BZgA) to develop a diabetes prevention strategy. In a two-day workshop jointly organized by the RKI and the BZgA, representatives from public health institutes in seven countries shared their expertise and knowledge on diabetes prevention and surveillance. Day one focused on NCD surveillance systems and emphasized both the strengthening of sustainable data sources and the timely and targeted dissemination of results using innovative formats. The second day focused on diabetes prevention strategies and highlighted the importance of involving all relevant stakeholders in the development process to facilitate its acceptance and implementation. Furthermore, the effective translation of prevention measures into real-world settings requires data from surveillance systems to identify high-risk groups and evaluate the effect of measures at the population level based on analyses of time trends in risk factors and disease outcomes. Overall, the workshop highlighted the close link between diabetes prevention strategies and surveillance systems. It was generally stated that only robust data enables effective prevention measures to encounter the increasing burden from diabetes and other NCDs.

[New Ways of Communication - Results of the Working Group 5 of the Forum Future Public Health, Berlin 2016]. / Neue Kommunikationsformen.

Good communication is an essential feature of public health. The existing communication channels from sender to receiver are increasingly supplemented or even replaced by new forms of communication such as social media in all areas of life. Public Health must adopt these changes in order to make its concerns and results accessible to different user groups. 1. Many groups of the population (e. g. migrants, socially disadvantaged) are hard to reach for purposes of communication. Different addressees need different forms of communication, including social media. Appropriate access routes must be identified and used for communication. 2. Strategies must be developed on how public health information can be effectively communicated via social media. They must be professionally sound, reliable and quality-assured, and regular updating must ensured. 3. Participation and dialogue are important elements of effective public health communication.

[Surveillance and Monitoring - Results of the Working Group 10 of the Forum Future Public Health, Berlin 2016]. / Surveillance und Monitoring.

Evidence-based health policies and evidence-based measures need comprehensive information on the health of the population. The existing health surveillance system provides reliable answers to many health policy issues. Nonetheless, there are many information gaps not yet covered or are only covered via short-term project solutions. 1. We need to strengthen and expand existing health surveillance and monitoring to continuously collect information on the health status of all population groups, including those that are difficult to reach through the existing surveys and methods, such as people with a migration background, or socially disadvantaged. This information must be regularly available on the national, regional and also on the local level. 2. The use of existing data on health, for example from official statistics or social insurance, must be significantly expanded and strengthened. The infrastructure for scientific analyses of health data as well as the transfer of information to policy makers and the public must be strengthened. Through an expansion of the resources for scientific processing of health-relevant questions, Public Health can make an important contribution to effective health policies.

[What potential do geographic information systems have for population-wide health monitoring in Germany? : Perspectives and challenges for the health monitoring of the Robert Koch Institute]. / Welches Potenzial haben Geoinformationssysteme für das bevölkerungsweite Gesundheitsmonitoring in Deutschland? : Perspektiven und Herausforderungen für das Gesundheitsmonitoring am Robert Koch-Institut.

Geographic information systems (GISs) are computer-based systems with which geographical data can be recorded, stored, managed, analyzed, visualized and provided. In recent years, they have become an integral part of public health research. They offer a broad range of analysis tools, which enable innovative solutions for health-related research questions. An analysis of nationwide studies that applied geographic information systems underlines the potential this instrument bears for health monitoring in Germany. Geographic information systems provide up-to-date mapping and visualization options to be used for national health monitoring at the Robert Koch Institute (RKI). Furthermore, objective information on the residential environment as an influencing factor on population health and on health behavior can be gathered and linked to RKI survey data at different geographic scales. Besides using physical information, such as climate, vegetation or land use, as well as information on the built environment, the instrument can link socioeconomic and sociodemographic data as well as information on health care and environmental stress to the survey data and integrate them into concepts for analyses. Therefore, geographic information systems expand the potential of the RKI to present nationwide, representative and meaningful health-monitoring results. In doing so, data protection regulations must always be followed. To conclude, the development of a national spatial data infrastructure and the identification of important data sources can prospectively improve access to high quality data sets that are relevant for the health monitoring.

[Regionalization of federal health reporting using the example of diabetes surveillance : Aims and results of the discussion between the Robert Koch Institute and the federal states]. / Regionalisierung der Gesundheitsberichterstattung am Beispiel Diabetes-Surveillance : Ziele und Ergebnisse des Bund-Länder-Gesprächs am Robert Koch-Institut.

Insufficiently treated diabetes mellitus can lead to severe comorbidities. National and international analyses show a continuous increase in diabetes prevalence over the last decades. Currently, an indicator-based national diabetes surveillance system is implemented at the Robert Koch Institute (RKI) to monitor and report on diabetes development on the basis of available primary and secondary data. The aim of the meeting was to go into deeper discussions and to integrate expectations and expertise of the federal states into the design of the national surveillance system. A close collaboration between the RKI and the federal states is intended.

[Integration of secondary data into national diabetes surveillance : Background, aims and results of the secondary data workshop at the Robert Koch Institute]. / Integration von Sekundärdaten in die Nationale Diabetes-Surveillance : Hintergrund, Ziele und Ergebnisse des Sekundärdaten-Workshops am Robert Koch-Institut.

Epidemiological data provide evidence that diabetes mellitus is a highly relevant public health issue in Germany as in many other countries. The Robert Koch Institute (RKI) is in the process of building a national diabetes surveillance system that is aimed at establishing indicator-based public health monitoring of diabetes population dynamics using primary and secondary data. The purpose of the workshop was to conduct an inventory of available secondary data sources and to discuss data contents, data access, data analysis examples in addition to the options for ongoing data use for diabetes surveillance.
