Asthma Surveillance - United States, 2006-2018.

ProblemAsthma is a chronic disease of the airways that requires ongoing medical management. Socioeconomic and demographic factors as well as health care use might influence health patterns in urban and rural areas. Persons living in rural areas tend to have less access to health care and health resources and worse health outcomes. Characterizing asthma indicators (i.e., prevalence of current asthma, asthma attacks, emergency department and urgent care center [ED/UCC] visits, and asthma-associated deaths) and determining how asthma exacerbations and health care use vary across the United States by geographic area, including differences between urban and rural areas, and by sociodemographic factors can help identify subpopulations at risk for asthma-related complications.Reporting Period2006–2018.Description of SystemThe National Health Interview Survey (NHIS) is an annual cross-sectional household health survey among the civilian noninstitutionalized population in the United States. NHIS data were used to produce estimates for current asthma and among them, asthma attacks and ED/UCC visits. National Vital Statistics System (NVSS) data were used to estimate asthma deaths. Estimates of current asthma, asthma attacks, ED/UCC visits, and asthma mortality rates are described by demographic characteristics, poverty level (except for deaths), and geographic area for 2016–2018. Trends in asthma indicators by metropolitan statistical area (MSA) category for 2006–2018 were determined. Current asthma and asthma attack prevalence are provided by MSA category and state for 2016–2018. Detailed urban-rural classifications (six levels) were determined by merging 2013 National Center for Health Statistics (NCHS) urban-rural classification data with 2016–2018 NHIS data by county and state variables. All subregional estimates were accessed through the NCHS Research Data Center.ResultsCurrent asthma was higher among boys aged <18 years, women aged ≥18 years, non-Hispanic Black (Black) persons, non-Hispanic multiple-race (multiple-race) persons, and Puerto Rican persons. Asthma attacks were more prevalent among children, females, and multiple-race persons. ED/UCC visits were more prevalent among children, women aged ≥18 years, and all racial and ethnic groups (i.e., Black, non-Hispanic Asian, multiple race, and Hispanic, including Puerto Rican, Mexican, and other Hispanic) except American Indian and Alaska Native persons compared with non-Hispanic White (White) persons. Asthma deaths were higher among adults, females, and Black persons. All pertinent asthma outcomes were also more prevalent among persons with low family incomes. Current asthma prevalence was higher in the Northeast than in the South and the West, particularly in small MSA areas. The prevalence was also higher in small and medium metropolitan areas than in large central metropolitan areas. The prevalence of asthma attacks differed by MSA category in four states. The prevalence of ED/UCC visits was higher in the South than the Northeast and the Midwest and was also higher in large central metropolitan areas than in micropolitan and noncore areas. The asthma mortality rate was highest in non-MSAs, specifically noncore areas. The asthma mortality rate was also higher in the Northeast, Midwest, and West than in the South. Within large MSAs, asthma deaths were higher in the Northeast and Midwest than the South and West.InterpretationDespite some improvements in asthma outcomes over time, the findings from this report indicate that disparities in asthma indicators persist by demographic characteristics, poverty level, and geographic location.Public Health ActionDisparities in asthma outcomes and health care use in rural and urban populations identified from NHIS and NVSS can aid public health programs in directing resources and interventions to improve asthma outcomes. These data also can be used to develop strategic goals and achieve CDC’s Controlling Childhood Asthma and Reducing Emergencies (CCARE) initiative to reduce childhood asthma hospitalizations and ED visits and prevent 500,000 asthma-related hospitalizations and ED visits by 2024.

Comparing the dangers of a stay in English and German hospitals for high-need patients.

To estimate the risk of an avoidable adverse event for high-need patients in England and Germany and the causal impact that has on outcomes. We use administrative, secondary data for all hospital inpatients in 2018. Patient records for the English National Health Service are provided by the Hospital Episode Statistics database and for the German health care system accessed through the Research Data Center of the Federal Statistical Office. We calculated rates of three hospital-acquired adverse events and their causal impact on mortality and length of stay through propensity score matching and estimation of average treatment effects. Patients were identified based on diagnoses codes and translated Patient Safety Indicators developed by the Agency for Healthcare Research and Quality. For the average hospital stay, the risk of an adverse event was 5.37% in the English National Health Service and 3.26% in the German health care system. High-need patients are more likely to experience an adverse event, driven by hospital-acquired infections (2.06%-4.45%), adverse drug reactions (2.37%-2.49%), and pressure ulcers (2.25%-0.45%). Adverse event risk is particularly high for patients with advancing illnesses (10.50%-27.11%) and the frail elderly (17.75%-28.19%). Compared to the counterfactual, high-need patients with an adverse event are more likely to die during their hospital stay and experience a longer length of stay. High-need patients are particularly vulnerable with an adverse event risking further deterioration of health status and adding resource use. Our results indicate the need to assess the costs and benefits of a hospital stay, particularly when care could be provided in settings considered less hazardous.

Trends in radiotherapy inpatient admissions in Germany: a\xa0population-based study over a\xa010-year period

ObjectiveWith the increasing complexity of oncological therapy, the number of inpatient admissions to radiotherapy and non-radiotherapy departments might have changed. In this study, we aim to quantify the number of inpatient cases and the number of radiotherapy fractions delivered under inpatient conditions in radiotherapy and non-radiotherapy departments.MethodsThe analysis is founded on data of all hospitalized cases in Germany based on Diagnosis-Related Group Statistics (G-DRG Statistics, delivered by the Research Data Centers of the Federal Statistical Office). The dataset includes information on the main diagnosis of cases (rather than patients) and the performed procedures during hospitalization based on claims of reimbursement. We used linear regression models to analyze temporal trends. The considered data encompass the period from 2008 to 2017.ResultsOverall, the number of patients treated with radiotherapy as inpatients remained constant between 2008 (N = 90,952) and 2017 (N = 88,998). Starting in January 2008, 48.9% of 4000 monthly cases received their treatment solely in a radiation oncology department. This figure decreased to 43.7% of 2971 monthly cases in October 2017. We found a stepwise decrease between December 2011 and January 2012 amounting to 4.3%. Fractions received in radiotherapy departments decreased slightly by 29.3 (95% CI: 14.0–44.5) fractions per month. The number of days hospitalized in radiotherapy departments decreased by 83.4 (95% CI: 59.7, 107.0) days per month, starting from a total of 64,842 days in January 2008 to 41,254 days in 2017. Days per case decreased from 16.2 in January 2008 to 13.9 days in October 2017.ConclusionOur data give evidence to the notion that radiotherapy remains a discipline with an important inpatient component. Respecting reimbursement measures and despite older patients with more comorbidities, radiotherapy institutions could sustain a constant number of cases with limited temporal shifts.

Energy Conservation Measures for a Research Data Center in an Academic Campus

Simulation and experimental studies were conducted to investigate energy consumption, develop ECMs (Energy Conservation Measures), and analyze temperature increase under a power failure scenario for a research data center at Youngstown State University. Two ECMs were developed to improve energy consumption by analyzing the thermal performance of the data center: (1) increase the return temperature in air conditioning vents; (2) provide cold aisle containment with the set point temperature increase. A transient analysis was conducted under a cooling system failure scenario to predict the temperature variation over time. The results suggest that it takes 600 s to increase the server inlet temperature by 16.1 °C for the baseline model. In addition, in the ECM #2, the maximum temperature at the server inlet did not reach 40 °C under the air conditioning system failure scenario, which is the maximum operating temperature of the ASHRAE A3 envelop.

Wahrnehmung des Klimawandels in Deutschland: Eine Längsschnittbefragung privater Haushalte

Dieser Beitrag präsentiert ausgewählte Ergebnisse einer Erhebung unter mehr als 6000 privaten Haushalten aus dem Frühjahr 2020 zur Relevanz des Klimawandels und seiner möglichen Auswirkungen und zieht Vergleiche mit vier thematisch ähnlichen Erhebungen aus den Jahren 2012 bis 2015. Trotz des langen Zeitraums von knapp zehn Jahren, über den sich die Erhebungen erstreckt haben, hat ein beachtlicher Teil von knapp 2000 Haushalten an allen fünf Erhebungen teilgenommen. Die aus diesen Erhebungen gewonnenen Paneldaten sind Bestandteil des Sozial-Ökologischen Panels des RWI, sie werden der Wissenschaft vom am RWI beheimateten Forschungsdatenzentrum Ruhr zur Verfügung gestellt. Es zeigten sich einige überraschende Ergebnisse, etwa dass der Bekämpfung des Klimawandels in allen fünf Erhebungen mit die geringste Bedeutung unter den zur Auswahl stehenden globalen Herausforderungen wie der Bekämpfung des Terrorismus oder von Hunger und Armut beigemessen wird.

Warenlagergebäude in Deutschland: Eine neue Methodik zur regionalen Quantifizierung der Flächeninanspruchnahme

In 2018, the building segment of warehouse buildings accounted for around a quarter of all newly constructed floor space in German non-residential buildings. Despite this great significance, there is a lack of in-depth analyses that look at construction activity in a differentiated manner by region and sector. As a result, little is known so far about the land-use implications of construction in this building segment. This paper a methodology to quantify the land use of warehouse buildings on a regional scale is presented. Based on a data set from the German Research Data Centre for the years 2000 to 2015 and by applying GIS-supported conversion parameters, propositions on the small-scale characteristics of land use are possible down to the municipal level. It is apparent that the segment of warehouse buildings is characterized by concentration effects in three respects: the buildings are getting larger and larger, they are increasingly being constructed by specialized logistics service providers and are spatially concentrated in only a few well-connected locations. As a result, contrary to the general trend, the land use of this segment is steadily increasing. A differentiated consideration of land use along spatial and functional contexts seems to be advisable for the success of national land-use targets.

Use and clinical outcome of veno-arterial extracorporeal membrane oxygenation in patients with acute pulmonary embolism and cardiopulmonary resuscitation

Abstract Funding Acknowledgements Type of funding sources: None. Background Extracorporeal membrane oxygenation (ECMO) is a life-saving therapy for patients with acute pulmonary embolism (PE) and concomitant cardiac arrest with the necessity of cardiopulmonary resuscitation (CPR). Little is known about the use and clinical outcome of veno-arterial (VA)-ECMO and adjunctive treatment strategies in patients with acute PE and CPR. Purpose In this context, we aimed to investigate the use of VA-ECMO alone or after systemic thrombolysis and its impact on in-hospital outcomes of patients with acute PE and CPR. Methods We analyzed data on the characteristics, treatments and in-hospital outcomes for all patients with acute PE (ICD-code I26) and CPR in Germany between the years 2005 and 2018 (source: Research Data Center (RDC) of the Federal Statistical Office and the Statistical Offices of the federal states, DRG Statistics 2005-2018, own calculations). Results Between 2005 and 2018, 1,172,354 patients with acute PE (53.5% females) were included in this analysis; of those, 77,196 (6.5%) presented with cardiac arrest and CPR. While more than one fourth of those patients were treated with systemic thrombolysis alone (n = 20,839 patients; 27.0%), a minority received a combination of thrombolysis + VA-ECMO (n = 165; 0.2%) or singular approach with VA-ECMO treatment alone (n = 588; 0.8%). The overall in-hospital mortality rate of PE patients with cardiac arrest was high with 83.8%. Non-survivors were considerable older than survivors (74 [IQR 63-81] vs. 69 [58-77]). In patients treated with VA ECMO alone the mortality rate was 71.1% and 69.7% when patients received Thrombolysis + VA-ECMO. Patients, who received thrombolysis without VA-ECMO had a higher mortality rate (83.8%). In order to investigate the impact of those different treatment strategies, a multivariate logistic regression analysis (adjusted for age, sex and comorbidities) demonstrated the lowest risk for in-hospital death in patients, who underwent the combination of Thrombolysis + VA-ECMO (OR, 0.61 [95% CI, 0.43-0.86], P = 0.004) or VA-ECMO alone (OR, 0.70 [0.58-0.84], P &amp;lt; 0.001) compared to patients without VA-ECMO and without thrombolysis. Use of thrombolysis alone in patients with PE and CPR lowering the risk regarding in-hospital death as well (OR, 0.95 [0.91-0.99], P = 0.013). Regarding temporal trends, the annual use of VA-ECMO increased from 0 in the year 2005 to the number of 138 in 2018 (ß 6.13 (4.62-6.76); p &amp;lt; 0.001) as well as for the combined treatment Thrombolysis + VA-ECMO (from 0 to 39 [ß 4.28 (3.68-4.89); p &amp;lt; 0.001]). Conclusion Patients with acute PE and CPR had a very high in-hospital mortality rate. Our data suggest, that VA-ECMO alone or after systemic thrombolysis should be considered as an option in this outstanding life-threatening situation to improve in-hospital outcome. Furthermore, our data highlight a marked increase in the number of PE patients treated with VA-ECMO indicating the structural health care progress between 2005 and 2018.

Management und Bereitstellung von Forschungsdaten in der Psychologie: Überarbeitung der DGPs-Empfehlungen

Providing to research data collected as part of publications and publicly funded research projects is now regarded as a central aspect of an open and transparent practice and is increasingly being called for by funding institutions and journals. To this end, researchers should strive to comply with the so-called FAIR principles (of data management), that is, research data should be findable, accessible, interoperable, and reusable. Systematic data management supports these goals and, at the same time, makes it possible to achieve them efficiently. With these revised recommendations on data management and data sharing, which also draw on feedback from a 2018 survey of its members, the German Psychological Society (Deutsche Gesellschaft fur Psychologie; DGPs) specifies important basic principles of data management in psychology. Initially, based on discipline-specific definitions of raw data, primary data, secondary data, and metadata, we provide recommendations on the degree of data processing necessary when publishing data. We then discuss data protection as well as aspects of copyright and data usage before defining the qualitative requirements for trustworthy research data repositories. This is followed by a detailed discussion of pragmatic aspects of data sharing, such as the differences between Type 1 and Type 2 data publications, restrictions on (embargo period), the definition of scientific use by secondary users of shared data, and recommendations on how to resolve potential disputes. Particularly noteworthy is the new recommendation of distinct access categories for data, each with different requirements in terms of data protection or research ethics. These range from completely open data without usage restrictions (access category 0) to data shared under a set of standardized conditions (e.g., reuse restricted to purposes; access category 1), individualized usage agreements (access category 2), and secure data under strictly controlled conditions (e.g., in a research data center; “access category 3). The practical implementation of this important innovation, however, will require data repositories to provide the necessary technical functionalities. In summary, the revised recommendations aim to present pragmatic guidelines for researchers to handle psychological research data in an open and transparent manner, while addressing structural challenges to data sharing solutions that are beneficial for all involved parties.

Postoperative Adjuvant Anastrozole for 10 Rather than 5 Years in Patients with Oestrogen Receptor-Positive Breast Cancer: AERAS, a Randomised Multicentre Open-Label Phase III Trial

Background: Treatment with an aromatase inhibitor for 5 years is the standard treatment for postmenopausal hormone receptor-positive breast cancer. We investigated the effects of extending this treatment to 10 years on the risk of breast cancer recurrence. Methods: This prospective, randomised, multicentre open-label phase III study assessed the effect of extending anastrozole treatment for an additional 5 years in postmenopausal patients with stage I–IIIA hormone receptor-positive breast cancer who were disease-free after treatment with either 5 years of anastrozole alone or 2–3 years of tamoxifen followed by 2–3 years of anastrozole. Patients were allocated randomly (1:1) to continue anastrozole (1 mg/day orally) for an additional 5 years or stop anastrozole, using the central computer at the Comprehensive Support Project for Oncology Research Data Centre. Randomisation was stratified by type of postoperative endocrine therapy, nodal status, prior adjuvant chemotherapy, and facility. The primary endpoint was disease-free survival, including breast cancer recurrence, second primary cancers, and death from any cause. This study is registered with UMIN clinical trials registry, number UMI00818. Findings: We enrolled 1697 patients from 117 facilities between November 2007 and November 2012. Patients were assigned randomly to the continue group (n=849) or the stop group (n=848). Follow-up information was available for 1593 patients (n=787 in the continue group, n=806 in the stop group) as the full analysis set. After a median follow-up of 5·1 years, there were 172 events involving disease recurrence or the occurrence of contralateral breast cancer (75 in the continue group and 97 in the stop group) and 40 deaths (21 in the continue group and 19 in the stop group). The 5-year disease-free survival rates were 91% (95% confidence interval [CI] 89–93) in the continue group and 86% (95% CI 83–88) in the stop group (hazard ratio [HR] for disease-free survival 0·61, 95% CI 0·46–0·82; p<0·0010, two-sided log-rank test). The 5-year overall survival rates were 98% in the continue group and 98% in the stop group (HR 1·13, p=0·7042). The 5-year distant disease-free survival rates were 95% in the continue group and 93% in the stop group (HR 0·68, p=0·0553). Sixty-seven second primary cancers occurred, including 24 in the continue group and 43 in the stop group. Menopausal or bone-related all-grade adverse events were more frequent among patients in the continue group than in the stop group, including higher incidences of hot flashes (111 [14%] vs 81 [10%]), stiff joints (162 [21%] vs 98 [12%]), arthralgia (294 [37%] vs 236 [29%]), and new-onset osteoporosis (370 [47%] vs 355 [44%]). Interpretation: Continuing adjuvant anastrozole for an additional 5 years after 5 years’ initial treatment with anastrozole or tamoxifen is safe and beneficial in postmenopausal patients with hormone receptor-positive breast cancer. Trial Registration: This study is registered with UMIN clinical trials registry, number UMI00818. Funding: The Comprehensive Support Project for Oncology Research of the Public Health Research Foundation Declaration of Interest: None to declare. Ethical Approval: Ethical approval was provided by local ethics committees in each hospital.

Dispersion in Dispersion: Measuring Establishment-Level Differences in Productivity

We describe new experimental productivity statistics, Dispersion Statistics on Productivity (DiSP), jointly developed and published by the Bureau of Labor Statistics (BLS) and the Census Bureau. Productivity measures are critical for understanding economic performance. Official BLS productivity statistics, which are available for major sectors and detailed industries, provide information on the sources of aggregate productivity growth. A large body of research shows that within-industry variation in productivity provides important insights into productivity dynamics. This research reveals large and persistent productivity differences across businesses even within narrowly defined industries. These differences vary across industries and over time and are related to productivity-enhancing reallocation. Dispersion in productivity across businesses can provide information about the nature of competition and frictions within sectors, and about the sources of rising wage inequality across businesses. Because there were no official statistics providing this level of detail, BLS and the Census Bureau partnered to create measures of within-industry productivity dispersion. These measures complement official BLS aggregate and industry-level productivity growth statistics and thereby improve our understanding of the rich productivity dynamics in the U.S. economy. The underlying microdata for these measures are available for use by qualified researchers on approved projects in the Federal Statistical Research Data Center (FSRDC) network. These new statistics confirm the presence of large productivity differences and we hope that these new data products will encourage further research into understanding these differences.

Venous thromboembolism in patients hospitalized for knee and hip joint replacement surgery

Abstract Background Venous thromboembolism (VTE) is a frequent acute cardiovascular disease, leading to significant morbidity and mortality worldwide. Major trauma, surgery, immobilisation and joint replacements are major provoking factors for VTE. In particular, patients undergoing knee and hip joint replacement surgery are at high risk of developing VTE perioperatively, even in the era of established pharmacological thromboprophylaxis. Without thromboprophylaxis, as many as 20–60% of patients may develop perioperative VTE. Purpose As recent studies indicate an increasing number of total knee and hip replacement surgeries in European countries and the United States, aims of our study were to investigate a) total burden and temporal trends of VTE complications following knee (KJR) and hip joint replacement (HJR) in Germany 2005–2016 and to identify b) predictors of VTE during hospitalization. Methods In an analysis of the nationwide German inpatient sample, we included all hospitalized patients with elective primary KJR and HJR in Germany between 2005 and 2016 (source: Research Data Center (RDC) of the Federal Statistical Office and the Statistical Offices of the federal states, DRG Statistics 2005–2016, own calculations). We analyzed temporal trends of surgical procedure, mortality, and VTE, and identified predictors of VTE. Results A total of 1,804,496 hospitalized patients underwent KJR (65.1% women, 53.4% aged ≥70 years) and 1,885,839 received HJR (59.1% women, 51.4% ≥70 years). VTE was documented in 23,297 (1.3% of total) KJR patients and in 11,554 HJR patients (0.6%). The number of primary KJR (129,832 in 2005 to 167,881 in 2016 [β-(slope)-estimate 1978 per year; 95% CI 1951 to 2004, P&amp;lt;0.001]) and primary HJR (145,223 in 2005 to 171,421 in 2016 [β-estimate 1818 per year; 95% CI 1083 to 2553, P&amp;lt;0.001]) increased during this twelve-year period. In-hospital VTE decreased from 1.9% to 0.9% (β-estimate −0.77 [95% CI: −0.81 to −0.72], P&amp;lt;0.001) after KJR and from 0.9% to 0.5% (β-estimate −0.71 (95% CI: −0.77 to −0.65), P&amp;lt;0.001) after HJR. In parallel, in-hospital death rate dropped from 0.14% (184 deaths) to 0.09% (146 deaths) (β-estimate −0.44 [95% CI: −0.59 to −0.30], P&amp;lt;0.001) after KJR and from 0.33% to 0.29% (β-estimate −0.11 (95% CI: −0.20 to −0.02), P=0.018) after HJR. Infections during hospitalization were associated with a higher VTE risk. VTE events were associated with in-hospital death in KJR (OR 20.86 [95% CI: 18.78–23.15], P&amp;lt;0.001) and HJR (OR 15.19 [95% CI: 14.19–16.86], P&amp;lt;0.001) independently from age, sex and comorbidities. Conclusions While total numbers of KJR and HJR interventions increased in Germany between 2005 and 2016, the rate of VTE decreased substantially. VTE complications were associated with 15-to 21-fold increase of in-hospital case-fatality rate. Perioperative infections increased the risk for VTE substantially.

Clinical impact of diabetes mellitus in patients hospitalized for myocardial infarction

Abstract Background Diabetes mellitus (DM) represents a major cardiovascular risk factor for coronary artery disease and myocardial infarction (MI). Purpose We aimed to assess in-hospital events and time trends in MI patients with and without DM between 2005 and 2016 in Germany. Methods The nationwide German inpatient sample 2005–2016 was used for statistical analysis (source: Research Data Center (RDC) of the Federal Statistical Office and the Statistical Offices of the federal states, DRG Statistics 2005–2016, own calculations). Hospitalized MI patients were stratified for the presence of DM and the impact of DM on in-hospital events was investigated. Results A total of 3,307,703 patients with acute MI (37.6% females, 56.8% aged ≥70 years) were included in the present analysis. Of these, 1,007,326 (30.5%) patients were coded for additional DM. More MI patients with DM were female (41.2% vs. 36.0%, P&amp;lt;0.001) and aged 70 years or older (64.3% vs. 53.5%, P&amp;lt;0.001). Presence of most cardiovascular risk factors was increased in coprevalence with DM compared to non-diabetics (obesity: 14.1% vs. 7.2%, essential arterial hypertension: 60.9% vs. 52.4%, hyperlipidaemia 40.5% vs. 37.8%, P&amp;lt;0.001), only smoking was more frequent in people without DM (4.8% vs. 8.5%, P&amp;lt;0.001). Additionally, DM was associated with an elevated occurrence of comorbidities like peripheral artery disease (10.8% vs. 4.5%, P&amp;lt;0.001), atrial fibrillation/flutter (26.5% vs. 19.6%, P&amp;lt;0.001) and acute or chronic kidney disease (39.8% vs. 21.8%, P&amp;lt;0.001). Recurrent MI events during the first 4 weeks after previous MI were more common in MI patients with DM (0.8% vs. 0.6%, P&amp;lt;0.001). Pneumonia (14.9% vs. 10.2%, P&amp;lt;0.001), acute kidney injury (8.6% vs. 5.2%, P&amp;lt;0.001) and stroke (3.4% vs. 2.7%, P&amp;lt;0.001) were more prevalent in MI patients with DM. Mortality was significantly increased in patients with DM (13.2% vs. 12.1%, P&amp;lt;0.001). While the proportion of MI patients with DM increased slightly from 29.8% in 2005 to 30.7% in 2016 (β 7.04 [95% CI 4.13–9.94], P&amp;lt;0.001), the in-hospital mortality rate of MI patients with DM decreased substantially from 15.2% in 2005 to 11.5% in 2016 (β −0.36 [95% CI: −0.38 to −0.34], P&amp;lt;0.001). Confirming this results, the univariate logistic regression analyses demonstrated that DM was associated with a higher in-hospital mortality (OR 1.1 [95% CI: 1.1–1.1], P&amp;lt;0.001), higher risk for recurrent MI (OR 1.3 [95% CI: 1.3–1.4], P&amp;lt;0.001), and higher frequency of acute kidney injury (OR 1.7 [95% CI: 1.7–1.7], P&amp;lt;0.001). Conclusions While the proportion of MI patients with DM increased only slightly from 2005 to 2016, the in-hospital mortality decreased substantially in MI patients with DM. DM was associated with an aggravated cardiovascular risk profile, higher prevalence of comorbidities and increased in-hospital mortality during hospitalization.

New administrative data on welfare dynamics in Germany: the Sample of Integrated Welfare Benefit Biographies (SIG)

The Sample of Integrated Welfare Benefit Biographies (SIG) is a new administrative longitudinal microdata set representative of recipients of Germany’s main welfare programme, the Unemployment Benefit II (UB II, Arbeitslosengeld II). The data set contains detailed longitudinal information on welfare receipt and labour market activities, and hence enables researchers to analyse the dynamics of benefit receipt, income and employment. A distinct feature of the SIG is that it provides information not only for individual benefit recipients but also for family members, including children and partners. This is possible because eligibility for UB II benefits depends on the household structure, and it is means-tested on household income. In addition to socio-demographic and regional information, the SIG contains extensive information on the employment biographies of benefit recipients and their household members from the Integrated Employment Biographies (IEB) of the Institute for Employment Research (IAB). This allows researchers to examine the interaction between labour market participation and benefit receipt. The SIG is available to researchers at the Research Data Centre (FDZ) of the Federal Employment Agency (BA) at the IAB.

The IAB Job Vacancy Survey: design and research potential

This article provides an overview of the IAB Job Vacancy Survey and its research potential. The IAB Job Vacancy Survey is a quarterly establishment survey covering the (un-)satisfied labor demand in Germany. This survey identifies the entire number of vacancies on the German labor market, including those vacancies that are not reported to the Federal Employment Agency. The main questionnaire obtains information about the number and structure of vacancies, future labor demand, the current economic situation and the expected development of participating establishments. In addition, the questionnaire collects information about the last new hiring and the last case of a failed recruitment process. Finally, the questionnaire enquires about employer attitudes and firms’ use of current labor market instruments. The Research Data Centre of the German Federal Employment Agency offers access to the data starting from the survey waves 2000 onwards.

Das Durchschnittsalter betrug 24 Jahre. Über die Hälfte stammte aus Asien. Über ein Drittel aller Leistungsempfänger befand sich in ambulanter (33,5 %) oder stationärer Behandlung (1,3 %). Zwischen den Bundesländern variierten die Leistungen zur Hilfe bei Krankheit sowie die gesundheitsbezogenen Pro-Kopf-Bruttoausgaben sehr stark. Die Gewährung von Leistungen bei Krankheit war in Aufnahmeeinrichtungen relativ gering. Mit Gesundheitskarte war die Inanspruchnahme stationärer Behandlung generell höher.Die gesundheitsbezogene Regelversorgung mit Hilfen in besonderen Fällen (§2 AsylbLG analog SGB XII) erreichte einen größeren Anteil an leistungsberechtigten Menschen mit 42,7 % am Jahresende als die Minimalversorgung nach §3 AsylbLG mit 29,0 %. Sie verursachte trotzdem im Vergleich weniger Bruttoausgaben.SchlussfolgerungEs wird empfohlen, §2 AsylbLG schon bei einer Voraufenthaltszeit ab 3 Monaten anzuwenden, um frühzeitiger die Hilfen analog Kap. 5–9 SGB XII gewähren zu können. Eine flächendeckende Einführung der Gesundheitskarte würde den Zugang verbessern.

Providing Digital Infrastructure for Audio-Visual Linguistic Research Data with Diverse Usage Scenarios: Lessons Learnt

This article describes the development of the digital infrastructure at a research data centre for audio-visual linguistic research data, the Hamburg Centre for Language Corpora (HZSK) at the University of Hamburg in Germany, over the past ten years. The typical resource hosted in the HZSK Repository, the core component of the infrastructure, is a collection of recordings with time-aligned transcripts and additional contextual data, a spoken language corpus. Since the centre has a thematic focus on multilingualism and linguistic diversity and provides its service to researchers within linguistics and other disciplines, the development of the infrastructure was driven by diverse usage scenarios and user needs on the one hand, and by the common technical requirements for certified service centres of the CLARIN infrastructure on the other. Beyond the technical details, the article also aims to be a contribution to the discussion on responsibilities and services within emerging digital research data infrastructures and the fundamental issues in sustainability of research software engineering, concluding that in order to truly cater to user needs across the research data lifecycle, we still need to bridge the gap between discipline-specific research methods in the process of digitalisation and generic digital research data management approaches.

German labour market data – Data provision and access for the international scientific community

AbstractThe Research Data Centre at the Institute for Employment Research (RDC-IAB) has been offering high-quality administrative and survey data on the German labour market for 15 years and has become one of the most important locations worldwide for researchers interested in data for labour market research. This article provides an overview of the RDC-IAB, including its data and access modes. The article presents two datasets in more detail: the Sample of Integrated Employment Biographies, a classic dataset, and the Linked Personnel Panel, a new dataset. Finally, this article provides insights into future infrastructure and data developments.

Experimental Description of Information Technology Equipment Reliability Exposed to a Data Center Using Airside Economizer Operating in Recommended and Allowable ASHRAE Envelopes in an ANSI/ISA Classified G2 Environment

Abstract Airside economizers lower the operating cost of data centers by reducing or eliminating mechanical cooling. It, however, increases the risk of reliability degradation of information technology (IT) equipment due to contaminants. IT Equipment manufacturers have tested equipment performance and guarantee the reliability of their equipment in environments within ISA 71.04-2013 severity level G1 and the ASHRAE recommended temperature-relative humidity (RH) envelope. IT Equipment manufacturers require data center operators to meet all the specified conditions consistently before fulfilling warranty on equipment failure. To determine the reliability of electronic hardware in higher severity conditions, field data obtained from real data centers are required. In this study, a corrosion classification coupon experiment as per ISA 71.04-2013 was performed to determine the severity level of a research data center (RDC) located in an industrial area of hot and humid Dallas. The temperature-RH excursions were analyzed based on time series and weather data bin analysis using trend data for the duration of operation. After some period, a failure was recorded on two power distribution units (PDUs) located in the hot aisle. The damaged hardware and other hardware were evaluated, and cumulative corrosion damage study was carried out. The hypothetical estimation of the end of life of components is provided to determine free air-cooling hours for the site. There was no failure of even a single server operated with fresh air-cooling shows that using evaporative/free air cooling is not detrimental to IT equipment reliability. This study, however, must be repeated in other geographical locations to determine if the contamination effect is location dependent.
