Purpose: Timely and accurate data on the epidemiology of sepsis are essential to inform policy decisions and research priorities. We aimed to investigate the validity of inpatient administrative health data (IAHD) for surveillance and quality assurance of sepsis care. Methods: We conducted a retrospective validation study in a disproportional stratified random sample of 10,334 inpatient cases of age ≥ 15 years treated in 2015–2017 in ten German hospitals. The accuracy of coding of sepsis and risk factors for mortality in IAHD was assessed compared to reference standard diagnoses obtained by a chart review. Hospital-level risk-adjusted mortality of sepsis as calculated from IAHD information was compared to mortality calculated from chart review information. Results: ICD-coding of sepsis in IAHD showed high positive predictive value (76.9–85.7% depending on sepsis definition), but low sensitivity (26.8–38%), which led to an underestimation of sepsis incidence (1.4% vs. 3.3% for severe sepsis-1). Not naming sepsis in the chart was strongly associated with under-coding of sepsis. The frequency of correctly naming sepsis and ICD-coding of sepsis varied strongly between hospitals (range of sensitivity of naming: 29–71.7%, of ICD-diagnosis: 10.7–58.5%). Risk-adjusted mortality of sepsis per hospital calculated from coding in IAHD showed no substantial correlation to reference standard risk-adjusted mortality (r = 0.09). Conclusion: Due to the under-coding of sepsis in IAHD, previous epidemiological studies underestimated the burden of sepsis in Germany. There is a large variability between hospitals in accuracy of diagnosing and coding of sepsis. Therefore, IAHD alone is not suited to assess quality of sepsis care. [ABSTRACT FROM AUTHOR]

- Abstract
Enrichment programs provide learning opportunities for a broader or deeper examination of curricular or extracurricular topics and are popular in gifted education. Herein, we investigated the effectiveness of a statewide extracurricular enrichment program for gifted elementary school children in Germany. The program implemented a "grass roots" strategy by which local units developed and offered the enrichment courses, which spanned a broad array of topics. The courses targeted different outcomes, including students' cognitive abilities, school achievement, interests, creativity, self-control, self-concept, and social competencies. We compared third-grade students attending the enrichment program (N =423) with nonattending third-grade students (N = 2,328) by means of a propensity score analysis. Specifically, we controlled for potential selection effects and estimated the average causal effect of the enrichment program for children attending the program. The findings revealed positive program effects on academic achievement but not on the other targeted outcomes.

Background: Sepsis is associated with about 20% of deaths worldwide. It often presents with non-specific initial symptoms, making its emergency treatment an interdisciplinary and cross-sectoral challenge. Three in four sepsis survivors suffers from new cognitive, psychological, or physical sequelae for which specific treatment concepts are scarce. The AVENIR project aims to improve the understanding of patient pathways, and subjective care experiences and needs along the entire healthcare pathway before, with and after sepsis. Based on this, concrete recommendations for the organization of care and patient information materials will be developed with close patient participation. Methods: Mixed-methods study including (1) analysis of anonymized nationwide health claims data from Germany, (2) linkage of health claims data with patient care reports (PCR) of emergency medical services from study regions in two federal states within Germany, and (3) qualitative exploration of the patient, relative, and care provider perspective on sepsis care. In (1), we analyze inpatient and outpatient health care utilization until 30 days pre-sepsis; clinical sepsis care including intra- and inter-hospital transfers; and rehabilitation, inpatient and outpatient aftercare of sepsis survivors as well as costs for health care utilization until 24 months post-sepsis. We attempt to identify survivor classes with similar health care utilization by Latent Class Analyses. In (2), PCR are linked with health claims data to establish a comprehensive database outlining care pathways for sepsis patients from pre-hospital to follow-up. We investigate e.g., whether correct initial assessment is associated with acute (e.g., same-day lethality) and long-term (e.g., new need for care, long-term mortality) outcomes of patients. We compare the performance of sepsis-specific screening tools such as qSOFA, NEWS-2 or PRESEP in the pre-clinical setting. In (3), semi-structured interviews as well as synchronous and asynchronous online focus groups are conducted and analyzed using qualitative content analyses techniques. Discussion: The results of the AVENIR study will contribute to a deeper understanding of sepsis care pathways in Germany. They may serve as a base for improvements and innovations in sepsis care, that in the long-term can contribute to reduce the personal, medical, and societal burden of sepsis and its sepsis sequelae. Trial registration: Registered at German Clinical Trial Register (ID: DRKS00031302, date of registration: 5th May 2023). [ABSTRACT FROM AUTHOR]

5. Dealing with Omitted and Not-Reached Items in Competence Tests: Evaluating Approaches Accounting for Missing Responses in Item Response Theory Models

- Abstract
Data from competence tests usually show a number of missing responses on test items due to both omitted and not-reached items. Different approaches for dealing with missing responses exist, and there are no clear guidelines on which of those to use. While classical approaches rely on an ignorable missing data mechanism, the most recently developed model-based approaches account for nonignorable missing responses. Model-based approaches include the missing propensity in the measurement model. Although these models are very promising, the assumptions made in these models have not yet been tested for plausibility in empirical data. Furthermore, studies investigating the performance of different approaches have only focused on one kind of missing response at once. In this study, we investigated the performance of classical and model-based approaches in empirical data, accounting for different kinds of missing responses simultaneously. We confirmed the existence of a unidimensional tendency to omit items. Indicating nonignorability of the missing mechanism, missing tendency due to both omitted and not-reached items correlated with ability. However, results on parameter estimation showed that ignoring missing responses was sufficient to account for missing responses, and that the missing propensity was not needed in the model. The results from the empirical study were corroborated in a complete case simulation.

Background: Sepsis is a substantial health care burden. Data on regional variation in sepsis incidence in Germany and any possible associations with regional socioeconomic deprivation and health care capacity is lacking.Methods: Ecological study based on the nationwide hospital Diagnosis-related Groups (DRG) statistics data of 2016. We identified sepsis by ICD-10-codes and calculated crude and age-standardized incidence proportions in the 401 administrative German districts. Associations between socioeconomic and health care capacity indicators and crude and age-adjusted sepsis incidence were investigated by simple and multiple negative binomial (NB) regressions.Results: In 2016, sepsis incidence was 178 per 100,000 inhabitants and varied 10-fold between districts. We found that the rate of students leaving school without certificate was significantly associated with crude and age-standardized explicit sepsis incidence in the simple and multiple NB regressions. While we observed no evidence for an association to the capacity of hospital beds and general practitioners, the distance to the nearest pharmacy was associated with crude- and age-standardized sepsis incidence. In the multiple regression analyses, an increase of the mean distance + 1000 m was associated with an expected increase by 21.6 [95% CI, 10.1, 33.0] (p < 0.001), and 11.1 [95% CI, 1.0, 21.2]/100,000 population (p = .026) after adjusting for age differences between districts.Conclusions: Residence in districts with lower socioeconomic status (e.g., less education) and further distance to pharmacies are both associated with an increased sepsis incidence. This warrants further research with individual-level patient data to better model and understand such dependencies and to ultimately design public health interventions to address the burden of sepsis in Germany.

Hospital-acquired infections are a common source of sepsis. Hospital onset of sepsis was found to be associated with higher acute mortality and hospital costs, yet its impact on long-term patient-relevant outcomes and costs is unknown. We aimed to assess the association between sepsis origin and acute and long-term outcomes based on a nationwide population-based cohort of sepsis patients in Germany. This retrospective cohort study used nationwide health claims data from 23 million health insurance beneficiaries. Sepsis patients with hospital-acquired infections (HAI) were identified by ICD-10-codes in a cohort of adult patients with hospital-treated sepsis between 2013 and 2014. Cases without these ICD-10-codes were considered as sepsis cases with community-acquired infection (CAI) and were matched with HAI sepsis patients by propensity score matching. Outcomes included in-hospital/12-month mortality and costs, as well as readmissions and nursing care dependency until 12 months postsepsis. We matched 33,110 HAI sepsis patients with 28,614 CAI sepsis patients and 22,234 HAI sepsis hospital survivors with 19,364 CAI sepsis hospital survivors. HAI sepsis patients had a higher hospital mortality than CAI sepsis patients (32.8% vs. 25.4%, RR 1.3, p <.001). Similarly, 12-months postacute mortality was higher (37.2% vs. 30.1%, RR=1.2, p <.001). Hospital and 12-month health care costs were 178% and 22% higher in HAI patients than in CAI patients, respectively. Twelve months postsepsis, HAI sepsis survivors were more often newly dependent on nursing care (33.4% vs. 24.0%, RR=1.4, p <.001) and experienced 5% more hospital readmissions (mean number of readmissions: 2.1 vs. 2.0, p <.001). HAI sepsis patients face an increased risk of adverse outcomes both during the acute sepsis episode and in the long-term. Measures to prevent HAI and its progression into sepsis may be an opportunity to mitigate the burden of long-term impairments and costs of sepsis, e.g., by early detection of HAI progressing into sepsis, particularly in normal wards; adequate sepsis management and adherence to sepsis bundles in hospital-acquired sepsis; and an improved infection prevention and control.

Objective: Incidence of primary mechanical complications and malpositions associated with landmark-guided central venous access procedures (CVAP) performed by experienced operators.Design: Prospective 5-year observational study on two intensive care units.Intervention: Only CVAPs using Seldinger technique were evaluated. Age, gender, puncture site, number of cannulation attempts, and complications within 24 hours and malpositions were recorded.Patients: 782 CVAPs in females aged 9-92 yrs and 1012 CVAPs in males aged 6-89 yrs.Results: We analyzed 1794 (1017 right- and 777 left-sided CVAP), of which 87.7% were accomplished without adverse events. More than one cannulation attempt was a risk factor for failed catheterization, other mechanical complications but not for malposition. Complications/malpositions were encountered in 220 CVAPs.In 51 CVAPs (2.8%) the cannulation failed at the attempted site, here 18 CVAPs were accompanied by further complications (35.3%). Otherwise, the rate for mechanical complications was low (3.3%). The most common mechanical complications (n = 127) were arterial punctures (n = 52; 2.9%), including four arterial cannulations (0.2%), and pneumothorax (n = 9; 0.6%). There was significant risk for arterial puncture with the internal jugular vein approach in comparison to the innominate vein (p = 0.004), but not to the subclavian vein (p = 0.065). Male patients had a lower risk for failure (2.1%) than females (3.8%, p = 0.028). One-hundred-twenty-one central venous catheters were malpositioned (6.7%) of which 35 were related to the left internal jugular vein.Conclusions: Even experienced operators cause a considerable number of early mechanical complications and malpositions. After two unsuccessful cannulation attempts failure and associated complications are very likely. [ABSTRACT FROM AUTHOR]- Published

The optimal treatment duration for vancomycin-resistant enterococcal (VRE) bacteraemia is still a matter of debate. The aim of the present study was to compare short-course (≤9 days) and long-course (≥10 days) antibiotic treatments in hospitalized adult patients with uncomplicated VRE bacteraemia. This retrospective study was conducted in four university hospitals in Germany. Adult patients with a positive blood culture for a VRE were screened from 1 January 2016 to 31 December 2018. Only patients who received a VRE-active antibiotic for at least 48 hours were included. The exclusion criteria were a survival of <10 days and a deep-seated source of infection requiring prolonged treatment. To compare the outcome of short-course therapy with that of long-course therapy, 30-day and 90-day overall mortality, relapse within 90 days, duration of hospitalization, and potential antibiotic-related adverse events were analysed by inverse probability of treatment weighting using the propensity score and by additional covariate adjustment. Of the 363 patients screened, 219 (60.3%) patients were included in the final analysis. Among them, 48 (21.9%) patients had underlying haematological diseases. Seventy-eight (35.6%) patients received short-course treatment (median, 7 days; interquartile range, 5–8 days) and 141 (64.4%) patients received long-course treatment (median, 15 days; interquartile range, 12–23.5 days). Thirty-day mortality was similar in both groups (19.2% vs. 22.0%; adjusted OR, 1.15; p 0.773). Duration of hospitalization (in total and after onset of bacteraemia) was significantly shorter (p < 0.05) in the short-course treatment group, whereas other secondary outcome parameters did not differ between both groups. Our study suggests that short-course treatment might not be associated with a worse outcome in patients with uncomplicated VRE bacteraemia. [ABSTRACT FROM AUTHOR]

- Abstract
Hundreds of thousands of individuals who experience lasting sequelae after sepsis and infections in Germany do not receive optimal care. In this White Paper we present measures for improvement, which were developed by a multidisciplinary expect panel as part of the SEPFROK project. Improved care rests on four pillars: 1. cross-sectoral assessment of sequelae and a structured discharge and transition management, 2. interdisciplinary rehabilitation and aftercare with structural support, 3. strengthening the specific health literacy of patients and families, and 4. increased research into causes, prevention and treatment of sequelae. To achieve this, appropriate cross-sectoral care structures and legal frameworks must be created., Competing Interests: Die Autorinnen/Autoren geben an, dass kein Interessenkonflikt besteht., (Thieme.

- Abstract
Background: An estimated 11 million deaths are associated with sepsis worldwide. The epidemiology of sepsis-associated deaths in Germany is insufficiently understood, as sepsis deaths cannot be identified in the German mono-causal causes of death statistics., Aim: We aim to analyze the epidemiology and characteristics of sepsis-associated hospital deaths as well as to describe regional disparities., Materials and Methods: Retrospective cohort study based on the 2016 German-wide diagnosis related groups (DRG) statistics. Sepsis-associated hospital deaths were identified by explicit and implicit sepsis ICD-10-GM codes. Deaths were described based on clinical characteristics and place of residence by official municipality key. The proportion of sepsis-associated hospital deaths among all deaths was calculated based on the national population statistics., Results: In 2016, there were 58,689 hospital deaths associated with explicitly coded sepsis (14.1% of all hospital deaths). Sepsis mortality was 73 per 100,000 inhabitants and varied 1.8-fold between federal states and 7.9-fold between districts. Of the national deaths, 6.4% were sepsis-associated hospital deaths. This proportion was highest in the 40-64 years age group (9.6%) and higher in males compared to females (7.7% vs. 5.2%). Compared to this, the proportion of deaths associated with implicitly coded sepsis was 47.2% among all hospital deaths and 21.6% among all national deaths., Discussion: Although the direct cause of death cannot be assessed based on our data, the high proportion of sepsis-associated deaths calls for further research and epidemiological surveillance, e.g., by cohort studies or based on multi-causal death statistics in Germany., (© 2021.

- Abstract
Importance: Sepsis survivorship is associated with postsepsis morbidity, but epidemiological data from population-based cohorts are lacking., Objective: To quantify the frequency and co-occurrence of new diagnoses consistent with postsepsis morbidity and mortality as well as new nursing care dependency and total health care costs after sepsis., Design, Setting, and Participants: This retrospective cohort study based on nationwide health claims data included a population-based cohort of 23.0 million beneficiaries of a large German health insurance provider. Patients aged 15 years and older with incident hospital-treated sepsis in 2013 to 2014 were included. Data were analyzed from January 2009 to December 2017., Exposures: Sepsis, identified by International Statistical Classification of Diseases and Related Health Problems, Tenth Revision (ICD-10) hospital discharge codes., Main Outcomes and Measures: New medical, psychological, and cognitive diagnoses; long-term mortality; dependency on nursing care; and overall health care costs in survivors at 1 to 12, 13 to 24, and 25 to 36 months after hospital discharge., Results: Among 23.0 million eligible individuals, we identified 159 684 patients hospitalized with sepsis in 2013 to 2014. The mean (SD) age was 73.8 (12.8) years, and 75 809 (47.5%; 95% CI, 47.2%-47.7%) were female patients. In-hospital mortality was 27.0% (43 177 patients; 95% CI, 26.8%-27.3%). Among 116 507 hospital survivors, 86 578 (74.3%; 95% CI, 74.1%-74.6%) had a new diagnosis in the first year post sepsis; 28 405 (24.4%; 95% CI, 24.1%-24.6%) had diagnoses co-occurring in medical, psychological, or cognitive domains; and 23 572 of 74 878 survivors (31.5%; 95% CI, 31.1%-31.8%) without prior nursing care dependency were newly dependent on nursing care. In total, 35 765 survivors (30.7%; 95% CI, 30.4%-31.0%) died within the first year. In the second and third year, 53 089 (65.8%; 95% CI, 65.4%-66.1%) and 40 959 (59.4%; 95% CI, 59.0%-59.8%) had new diagnoses, respectively. Health care costs for sepsis hospital survivors for 3 years post sepsis totaled a mean of €29 088/patient ($32 868/patient) (SD, €44 195 [$49 938]). New postsepsis morbidity (>1 new diagnosis) was more common in survivors of severe sepsis (75.6% [95% CI, 75.1%-76.0%]) than nonsevere sepsis (73.7% [95% CI, 73.4%-74.0%]; P < .001) and more common in survivors treated in the intensive care unit (78.3% [95% CI, 77.8%-78.7%]) than in those not treated in the intensive care unit (72.8% [95% CI, 72.5%-73.1%]; P < .001). Postsepsis morbidity was 68.5% (95% CI, 67.5%-69.5%) among survivors without prior morbidity and 56.1% (95% CI, 54.2%-57.9%) in survivors younger than 40 years., Conclusions and Relevance: In this study, new medical, psychological, and cognitive diagnoses consistent with postsepsis morbidity were common after sepsis, including among patients with less severe sepsis, no prior diagnoses, and younger age. This calls for more efforts to elucidate the underlying mechanisms, define optimal screening for common new diagnoses, and test interventions to prevent and treat postsepsis morbidity.

- Abstract
Influenza and pneumococcal vaccinations are recommended in the elderly to reduce life-threatening complications like sepsis. Protection may be reduced with increasing age. We aimed to assess the effectiveness of both vaccines in the elderly by performing a retrospective cohort study of 138,877 individuals aged ≥60 y in Germany, who were insured in a large statutory health insurance (AOK PLUS). We used longitudinal claims data to classify individuals according to vaccination status 2008-2014, and assessed vaccine effectiveness (VE) in 2015 and 2016. Inverse probability weighting based on generalized propensity scores was used to adjust for systematic between-group differences. Influenza vaccination was associated with a reduction of hospital treatment in laboratory-confirmed influenza in 2015 (VE = 41.32 [95%CI 0.85, 65.26]), but had no significant impact on the overall influenza incidence. Complications of influenza (pneumonia and sepsis) were reduced in 2016. We found a rise in influenza-like illness and acute respiratory infections in both years and an increased 90-d mortality after hospital-treated pneumonia in vaccinees in 2015. Pneumococcal vaccination was effective in preventing hospital-treated pneumonia within the first and second year after vaccination (VE = 52.45 [13.31, 73.92] and 46.04 [5.46, 69.21], respectively), but had no impact on sepsis incidence or pneumonia mortality. Influenza and pneumococcal vaccination can prevent severe complications from influenza and hospital-treated pneumonia in the elderly, respectively. Vaccine effects differ between years and seasons and are partly difficult to interpret. Despite extensive efforts to adjust for between-group differences, residual bias cannot be ruled out, possibly explaining signals like increased ILI or pneumonia mortality.

- Abstract
We investigated the development of narcissistic admiration (i.e., the assertive or extraverted dimension of narcissism; Back et al., 2013) and Machiavellianism (Mach) in early adulthood. Specifically, we examined (a) mean-level changes in narcissistic admiration and Mach during early adulthood and (b) how studying economics and experiencing any of 30 life events were related to individual differences in changes in narcissistic admiration and Mach. We used longitudinal data from 2 cohorts of young adults in Germany (N1 = 4,962 and N2 = 2,572). The mean levels of narcissistic admiration remained stable over time. Life events analyses indicated that narcissistic admiration increased among people who experienced a positively evaluated change in their eating or sleeping habits, a positively evaluated romantic break-up, or a negatively evaluated failure on an important exam. The mean levels of Mach decreased during early adulthood in both cohorts. Life events analyses showed that Mach decreased for only the 91% of young adults who had started a new job and evaluated it positively, suggesting that mastering occupational roles mitigates Mach in early adulthood. The results will be discussed in the light of previous longitudinal studies on narcissism and the Big Five and cross-sectional studies on how age is related to narcissism and Mach.
