School-based oral health education increases caries inequalities.

OBJECTIVE: To evaluate the effect of one and half years of an oral health promotion program in primary schools. DESIGN: A cluster-randomized controlled trial. PARTICIPANTS: 740 students aged 9-12 years (48% female) recruited from the fifth grade of 18 different primary schools in West Pomerania, Germany. METHODS: General and oral health education was provided to the teachers in the intervention schools, which they conveyed to their students. No additional measures were conducted in the control schools. Medical and dental school examinations, as well as questionnaires for the students and their parents were conducted at baseline and follow-up. Data were analysed using Poisson regression models. RESULTS: A significant incident rate ratio between caries increment was found, with a 35% higher risk in the control group. However, parents' socioeconomic characteristics modified the effect of the program on their children, as high socio-economic status in the intervention group was associated with 94% reduction in the incidence risk ratio (p ⟨ 0.001). CONCLUSIONS: The program was effective in improving dental health among students with higher socio-economic status. No preventive effect could be found in low socio-economic status groups.

Supporting family dementia caregivers: testing the efficacy of dementia care management on multifaceted caregivers' burden.

OBJECTIVES: Current research suggests that dementia care management (DCM) can decrease burden and associated health impairments of caregivers. The objective of this secondary analysis is to investigate the impact of DCM on multifaceted caregivers' burden dimensions by differentiating between objective and subjective burden. METHODS: A sample of n = 317 dyads of caregivers and community-dwelling people with dementia (PwD) participated in a general practitioner-based, cluster-randomized intervention trial (Identifier:NCT01401582) with two arms and comprehensive data assessment at baseline and 12-month follow-up. Data provided by the caregiver included an inventory with 88 items in 20 different dimensions. RESULTS: Caregivers in the intervention 'DCM' group showed decreased caregiver burden, especially in caregivers' objective burden due to caring (i.e. emotional support), caregivers' subjective burden due to behavior change (i.e. cognition, aggression and resistance, depression, late symptoms) and caregivers' subjective burden due to perceived conflicts between needs and responsibilities to care (i.e. financial losses) compared to caregivers in the control 'care as usual' group, which showed significant increased caregiver burden after 12 months. CONCLUSION: Our findings support evidence for the effectiveness of DCM to lower family dementia caregivers' burden in multifaceted dimensions.

[Financing Regional Dementia Networks in Germany: Determinants of Sustainable Healthcare Networks]. / Finanzierung regionaler Demenznetzwerke: Determinanten einer nachhaltigen Finanzierung am Beispiel spezialisierter Gesundheitsnetzwerke.

OBJECTIVES: Analysis of practice-based financing concepts in German dementia networks (DN); Provision of sustainable financing structures and their determinants in DN. MATERIALS AND METHODS: Qualitative expert interviews with leaders of 13 DN were conducted. A semi-structured interview guide was used to analyse four main topics: Finance-related organization, cost, sources of funding and financial sustainability. RESULTS: DN were primarily financed by membership fees, earnings of services provided, public funds and payments by municipalities or health care providers. 63% of the DN reported a financial sustainability. Funds to support the interpersonal expanding, a mix of internal and external financing sources and investments of the municipality were determinants of a sustainable financing. Overall, DN in rural areas seemed to be disadvantaged due to a lack of potential linkable service providers. CONCLUSION: DN in urban regions are more likely able to gather sustainable funding resources. A minimum funding of 50.000 €/year for human resources coordinating the DN, seems to be a threshold for a sustainable DN.

[Social medical/public health assessment of the ability to work regarding urological and urooncological diseases]. / Sozialmedizinische Begutachtung der Arbeits- und Erwerbsfähigkeit bei urologischen/uroonkologischen Erkrankungen.

The primary objectives of modern urooncological treatment concepts are quality of life, reintegration and participation. Urological rehabilitation supports the overcoming of side effects of disease and treatment, which is necessary for the timely return to work life. Social medical assessment reflects the individual overall results of the entire treatment process concerning oncological prognosis, physical and mental capacity and resilience.

The impact of socioeconomic factors on the efficiency of voluntary toxoplasmosis screening during pregnancy: a population-based study.

BACKGROUND: Congenital toxoplasmosis is associated with severe complications. German state health insurance covers rubella, but not toxoplasmosis, immunity screening. We analysed the effect of socioeconomic factors on the efficiency of private toxoplasmosis screening during pregnancy. METHODS: Toxoplasmosis and rubella screening data (n = 5402 mothers) were collected within the population-based Survey of Neonates in Pomerania (SNiP). RESULTS: At the first-trimester screening, 34.4 % (88.1 %) of expecting mothers were immune to toxoplasmosis (rubella). Susceptibility for toxoplasmosis (rubella) was observed in 39.6 % (8.9 %) and 25.8 % (2.95 %) were not tested. Data on a 2(nd) screening were available in a subgroup of women with negative immunity showing less than 45 % participation rate. Active toxoplasmosis (no rubella) infection was observed in 0.3 % (n = 17) of pregnant women. A multiple logistic regression model (AIC = 719.67; AUC = 0.725) revealed that the likelihood of participating in a second toxoplasmosis screening increased among women with a good level of education and a steady partnership and decreased with paternal unemployment and the absence of breastfeeding. The highest probability of non-participation in toxoplasmosis screening was found among women with temporal burden and family responsibilities. A cost-benefit analysis showed that covering general screening for toxoplasmosis with health insurance saved costs. CONCLUSION: Toxoplasmosis carried a substantial risk of infection during pregnancy. Although increased socioeconomic status was positively associated with the participation in toxoplasmosis screening, this was not the case when pregnant women had strong temporal burden and family responsibilities. This data supports the need for toxoplasmosis screening among pregnant women as a general healthcare benefit covered by insurance.

[Social medicine assessment after surgical and targeted treatment of renal cell cancer]. / Sozialmedizinische Begutachtung nach operativer und zielgerichteter Therapie des Nierenzellkarzinoms.

In Germany, renal cell cancer counts for 2.5 % of all carcinomas in women and 3.5 % in men. Curative therapy ensures good chances of recovery. But there might be permanent complications like renal insufficiency, pain, incisional hernia, flank muscle relaxation, and paresis. In addition, targeted therapy is associated with several potential side effects. In both therapy groups, severe psychological problems may occur. Still employed patients with these problems must be examined by an expert to estimate the possibilities of returning to working (positive scope of work) and occupations which can not be performed anymore (negative scope of work).

[Social medical/public health assessment of bladder cancer after curative and adjuvant therapy]. / Sozialmedizinische Begutachtung nach kurativer und adjuvanter Therapie des Harnblasenkarzinoms.

Radical cystectomy and urinary diversion are a challenge for patients. Requirements for the successful participation of the patient are sufficient urinary diversion management and recuperation/recovery as the result of urological rehabilitation. A social medical assessment reviews the individual oncological prognosis and the rehabilitation results to determine the return to work.

[Social medicine assessment of patients with prostate cancer]. / Sozialmedizinische Begutachtung bei Patienten mit Prostatakarzinom.

Due to the increasing incidence of prostate cancer in social-medicine-relevant age groups, a correct subject-specific evaluation of the professional capacity of these patients with all stages of disease is required. A concluding assessment is only significant when based on concrete functional deficits.

MOSAIC--A Modular Approach to Data Management in Epidemiological Studies.

INTRODUCTION: In the context of an increasing number of multi-centric studies providing data from different sites and sources the necessity for central data management (CDM) becomes undeniable. This is exacerbated by a multiplicity of featured data types, formats and interfaces. In relation to methodological medical research the definition of central data management needs to be broadened beyond the simple storage and archiving of research data. OBJECTIVES: This paper highlights typical requirements of CDM for cohort studies and registries and illustrates how orientation for CDM can be provided by addressing selected data management challenges. METHODS: Therefore in the first part of this paper a short review summarises technical, organisational and legal challenges for CDM in cohort studies and registries. A deduced set of typical requirements of CDM in epidemiological research follows. RESULTS: In the second part the MOSAIC project is introduced (a modular systematic approach to implement CDM). The modular nature of MOSAIC contributes to manage both technical and organisational challenges efficiently by providing practical tools. A short presentation of a first set of tools, aiming for selected CDM requirements in cohort studies and registries, comprises a template for comprehensive documentation of data protection measures, an interactive reference portal for gaining insights and sharing experiences, supplemented by modular software tools for generation and management of generic pseudonyms, for participant management and for sophisticated consent management. CONCLUSIONS: Altogether, work within MOSAIC addresses existing challenges in epidemiological research in the context of CDM and facilitates the standardized collection of data with pre-programmed modules and provided document templates. The necessary effort for in-house programming is reduced, which accelerates the start of data collection.

[The integration of telemedicine concepts in the regional care of rural areas: Possibilities, limitations, perspectives]. / Telemedizinische Versorgungskonzepte in der regionalen Versorgung ländlicher Gebiete : Möglichkeiten, Einschränkungen, Perspektiven.

In rural areas with a low population density and (imminent) gaps in regional health care, telemedicine concepts can be a promising option in supporting the supply of medical care.Telemedicine connections can be established between different health care providers (e.g., hospitals) or directly between health care providers and patients.Different scenarios for the implementation of telemedicine have been developed, from the monitoring of chronically ill patients to the support of acute care. Examples of frequently applied telemedicine concepts are teleradiology, telemedicine stroke networks, and the telemedicine monitoring of patients with heart failure. The development of concepts for other indications and patient groups is apparently difficult in Germany; one reason could be that research institutions are involved in only a small number of projects. However, the participation of research institutes would be of importance in creating more scientific evidence. The development of appropriate evaluation designs for analyzing the effectiveness of telemedicine concepts and economic effects is an important task and challenge for the future. Mandatory evaluation criteria should be developed to provide a basis for the translation of positively evaluated telemedicine concepts into routine care.

[Outpatient Care of People with Dementia within Residential Communities in Germany--Care Potential and Cost]. / Ambulant betreute Demenz-Wohngemeinschaften in Deutschland--Pflegepotenzial und Kosten.

BACKGROUND: Since the 1980s dementia residential communities (DRC) have been established as part of the health-care landscape and as an alternative to inpatient long-term nursing care. Information about (a) the residents (b) the care potential and (c) the cost of DRCs are still lacking. METHODS: A nation-wide postal questionnaire was sent to n=332 DRCs managed by n=151 organizations. The sample was based on an internet search with various combinations of search terms such as "outpatient" and "residential care communities". The questionnaire contained questions about the resident's social-demography, nursing care level and the utilization, financing and cost structures of DRCs. RESULTS: In total 81 organizations with n=88 DRCs replied to the questionnaire. Overall n=794 persons were living in these communities, most of the residents were female (80%, n=522), and 67% of the residents were older than 80 years. The nursing care level was high, 27% of the DRC residents reached the highest stage. Only 5% of the DRCs capacity was vacant. 86% of the communities stated to be able to provide nursing care for the residents until the end of their life. Almost half (48%) of the residents received money from the social welfare. The total average amount of cost per place per month was 3,265.08€ (excluding costs of services related to health insurance). CONCLUSIONS: DRCs are caring for residents with high nursing care levels. Costs of these communities vary to a large extent but are in addition comparable to inpatient long-term nursing care. Thus, interested persons should obtain information about cost, financing and care concepts. The low level of vacant capacity demonstrates the demand for DRCs in Germany. Studies with the objective to evaluate quality of care, care concepts and suitable clients for those communities are needed to develop this living concept.

Latest-generation catheterization systems enable invasive submillisievert coronary angiography.

BACKGROUND: The radiation risk of patients undergoing invasive cardiology remains considerable and includes skin injuries and cancer. To date, submillisievert coronary angiography has not been considered feasible. PATIENTS AND METHODS: In 2011, we compared results from 100 consecutive patients undergoing elective coronary angiography using the latest-generation flat-panel angiography system (FPS) with results from examinations by the same operator using 106 historic controls with a conventional image-intensifier system (IIS) that was new in 2002. RESULTS: The median patient exposure parameters were measured as follows: dose-area product (DAP) associated with radiographic cine acquisitions (DAP(R)) and fluoroscopy (DAP(F)) scenes, radiographic frames and runs, and cumulative exposure times for radiography and fluoroscopy. On the FPS as compared to the traditional IIS, radiographic detector entrance dose levels were reduced from 164 to 80 nGy/frame and pulse rates were lowered from 12.5/s to 7.5/s during radiography and from 25/s to 4/s during fluoroscopy. The cardiologist's performance patterns remained comparable over the years: fluoroscopy time was constant and radiography time even slightly increased. Overall patient DAP decreased from 7.0 to 2.4 Gy × cm(2); DAP(R), from 4.2 to 1.7 Gy × cm(2); and DAP(F), from 2.8 to 0.6 Gy × cm(2). Time-adjusted DAP(R)/s decreased from 436 to 130 mGy × cm(2) and DAP(F)/s, from 21.6 to 4.4 mGy × cm(2). Cumulative patient skin dose with the FPS amounted to 67 mGy, and the median (interquartile range) of effective dose was 0.5 (0.3 … 0.7) mSv. CONCLUSION: Consistent application of radiation-reducing techniques with the latest-generation flat-panel systems enables submillisievert coronary angiography in invasive cardiology.

Genetic, psychosocial and clinical factors associated with hippocampal volume in the general population.

The hippocampus--crucial for memory formation, recall and mood regulation--is involved in the pathophysiology of dementia and depressive disorders. Recent genome-wide association studies (GWAS) have identified five genetic loci associated with hippocampal volume (HV). Previous studies have described psychosocial and clinical factors (for example, smoking, type 2 diabetes and hypertension) to have an impact on HV. However, the interplay between genetic, psychosocial and clinical factors on the HV remains unclear. Still, it is likely that genetic variants and clinical or psychosocial factors jointly act in modifying HV; it might be possible they even interact. Knowledge of these factors might help to quantify ones individual risk of or rather resilience against HV loss. We investigated subjects (N=2463; 55.7% women; mean age 53 years) from the Study of Health in Pomerania (SHIP-2; SHIP-TREND-0) who underwent whole-body magnetic resonance imaging (MRI) and genotyping. HVs were estimated with FreeSurfer. For optimal nonlinear model fitting, we used regression analyses with restricted cubic splines. Genetic variants and associated psychosocial or clinical factors were jointly assessed for potential two-way interactions. We observed associations between HV and gender (P<0.0001), age (P<0.0001), body height (P<0.0001), education (P=0.0053), smoking (P=0.0058), diastolic blood pressure (P=0.0211), rs7294919 (P=0.0065), rs17178006 (P=0.0002), rs6581612 (P=0.0036), rs6741949 (P=0.0112) and rs7852872 (P=0.0451). In addition, we found three significant interactions: between rs7294919 and smoking (P=0.0473), rs7294919 and diastolic blood pressure (P=0.0447) and between rs7852872 and rs6581612 (P=0.0114). We suggest that these factors might have a role in the individual susceptibility to hippocampus-associated disorders.

[Demographic change : challenges to ophthalmological patient-centered care]. / Demografischer Wandel : Herausforderungen für die ophthalmologische Versorgung.

BACKGROUND: Demographic change not only affects patients with ophthalmological diseases but also ophthalmologists. OBJECTIVES: The aim of this article is to evaluate the consequences of an aging society on health care provision. How can these challenges be overcome? MATERIAL AND METHODS: Evaluation of publications from the German Federal Statistical Office about the current and projected population, analysis of own studies about health care provision, utilization, and delivery as well as the presentation and discussion of regulatory and organizational conditions. RESULTS: There is a continuous increase in chronic and age-related diseases. At the same time the prevalence of multimorbidity and the number of patients dependent on long-term care is rising, leading to an increase in the demand for ophthalmological care. Regarding health care providers we observed a cutback in qualified ophthalmological personnel, especially for remote areas thus causing difficulties in providing adequate eye care to the population. CONCLUSION: To deliver health care to a growing number of patients with a decreasing number of medical professionals is the major challenge of demographic change. This will have an enormous impact on ophthalmological health care in terms of maintaining high quality health services covering a nationwide area.

[Morbidity developments in the demographic change: availability of medical services in regional care]. / Morbiditätsentwicklung im demographischen Wandel: Verfügbarkeit medizinischer Leistungen in der regionalen Versorgung.

The proportion of older people will increase strongly in Germany in the coming years. A consequence is an increase in patient numbers particularly for age-associated diseases and multimorbidity. Higher numbers of patients mean greater use of medical services and a higher demand for home visits with older patients. Although the total population is declining, the need for doctors will increase in certain medical areas, for example in the primary care sector. In many rural areas the reoccupation of vacant practices is already becoming a problem. Innovative, flexible and regionally organized healthcare concepts are necessary to ensure adequate medical care. Duties and responsibilities must be transferred between health professions and across sector boundaries, for example on the basis of delegation concepts, telemedicine and better cooperation between the outpatient and inpatient settings.

[Memorandum - research funding of prevention]. / Memorandum - Forschungsförderung Prävention.

The memorandum of the research funding of prevention has been devised within the framework of the Prevention Research Funding Programme of the Federal Ministry of Education and Research. It consists not only of the obtained findings of the research-practice co-operation but also of recommendations for the implementation of prospective, innovational, effective, practice-oriented and sustainable research. The respective knowledge has been acquired from quantitative surveys on the experiences of scientists and practice partners within the prevention research funding project as well as from extensive qualitative methods of structured group evaluation. A participatory co-operation between research and practice based on mutual respect, trust and recognition is seen as mandatory for the further development of both prevention and health promotion research. Research and practice partners are required to engage in an ab initio collaboration starting from the conception phase, whereby it is advisable to encourage and fortify the communication between research, practice and funding partners by systematic surveillance in form of a meta-project. In addition, the inclusion of the target population from the outset and on a collaborative basis is considered as beneficial in order to ensure the practical application of the research findings. Furthermore, innovatory research designs which are able to provide a framework for internal flexibility, continuous re-assessment and adjustment are fundamental for the implementation of practice-oriented research. Moreover, a dynamic co-operation between different groups of interest not only depends on sharing responsibility but also on sufficient funding for both research and practice, which is particularly important for the transfer and communication of the attained findings. With regard to the evaluation of both effectiveness and sustainability of interventions, a research funding project is required which makes long-term results possible through the utilization of regulated monitoring and guarantees quality and continuous effectiveness. Furthermore, in order to stimulate progress within the basic theories of prevention and health promotion, it is also essential for a funding project to focus on elementary concepts. Additionally, for the efficient and sustainable development of health within a population it is advisable to apply both self-contained research and the involvement of primary prevention and health promotion to research projects concerning health, social affairs, education, work and environment.

[The German National Cohort]. / Die Nationale Kohorte.

The German National Cohort (GNC) is a joint interdisciplinary endeavour of scientists from the Helmholtz Association, universities and other German research institutes. Its aim is to investigate the development of major chronic diseases (cardiovascular diseases, cancer, diabetes, neurodegenerative psychiatric diseases, pulmonary and infectious diseases), the subclinical stages and functional changes. In 18 study centres across Germany, a representative sample of the general population will be drawn to recruit in total 200,000 men and women aged 20-69 years. In addition to interviews and questionnaires, the baseline assessment includes a series of medical examinations and the collection of a diverse range of biomaterials. In 20% of the participants, an intensified assessment programme is foreseen. Also in 40,000 participants, magnetic resonance imaging of the whole body, heart and brain will be performed. After 5 years, a follow-up examination will be performed in all subjects and active follow-up by postal questionnaires is planned every 2-3 years. The GNC will provide an excellent basis for future population-based epidemiology in Germany and results will help identify new and tailored strategies for prevention, prediction and early detection of major diseases.

[Time required and associated costs for implementation of home medication review with associated pharmaceutical and medical evaluation in the ambulatory health care sector]. / Zeitbedarf und Kosten für die Umsetzung eines Medikamentenreviews und assoziierter pharmazeutischer und medizinischer Evaluation im ambulanten Versorgungssektor.

INTRODUCTION: We aimed to estimate the time which is needed to conduct a home medication review (HMR) in the context of the AGnES implementation studies (AGnES=GP-supporting, community-based, e-health-assisted, systemic intervention). In a subsequent step associated costs were calculated. METHODS: IT-supported HMR were conducted by specially qualified AGnES-practice assistants to detect selected drug-related problems (DRP). The patient received pharmaceutical care by their local pharmacist and medical evaluation by their GP, respectively. RESULTS: The data from 471 patients (w: 339; m: 132) were evaluated (median age: w=81; m=78). The interview to detect selected DRP was 6 min (median) long. The subsequent drug record took 14.4 min. There was an additional effort for documentation of 5 min. The local pharmacist needed a median time of 15 min for pharmaceutical evaluation, whereas the GP needed 8 min. The estimated costs accounted for: AGnES-practice assistant: 9.12 €; pharmacist: 11.05 €; GP: 6.30 €. The overall estimated costs were 26.47 €. CONCLUSION: For the first time we present objective costs which were associated with the implementation of HMR. Due to high DRP-induced costs the HMR should be mandatory for groups with a high risk like for the occurrence of DRP.

Can the Hazard Assessment and Critical Control Points (HACCP) system be used to design process-based hygiene concepts?

Recently, the HACCP (Hazard Analysis and Critical Control Points) concept was proposed as possible way to implement process-based hygiene concepts in clinical practice, but the extent to which this food safety concept can be transferred into the health care setting is unclear. We therefore discuss possible ways for a translation of the principles of the HACCP for health care settings. While a direct implementation of food processing concepts into health care is not very likely to be feasible and will probably not readily yield the intended results, the underlying principles of process-orientation, in-process safety control and hazard analysis based counter measures are transferable to clinical settings. In model projects the proposed concepts should be implemented, monitored, and evaluated under real world conditions.
