Specialist palliative care until the very end of life - reports of family caregivers and the multiprofessional team

BACKGROUND

Specialist palliative care (SPC) includes care for incurably ill patients and their family caregivers at home or on a palliative care ward until the very end of life. However, in the last days of life, patients can rarely express their needs and little is known about SPC outcomes as reported by multiprofessional SPC teams and family caregivers.

METHODS

Using the Palliative Care Outcome Scale (POS; Score 0-40), proxy assessments of SPC outcomes in the patient's last 3 days of life were performed by SPC teams and primary family caregivers of three home care and three inpatient services. Additional questions were asked about problems solved 'particularly well' or 'inadequately' (last 7 days), which were content analyzed and quantified.

RESULTS

Proxy assessments by SPC teams were available in 142 patients (of whom 51% had died at home). Family caregiver assessments exist for a subgroup of 60 of these patients. SPC teams (POS total score: mean 13.8, SD 6.3) reported SPC outcomes slightly better than family caregivers (mean 16.7, SD 6.8). The POS items consistently rated as least affected (= 0) by both, SPC teams and family caregivers, were 'not wasted time' (team 99%/family caregivers 87%), 'information' (84%/47%) and 'support' (53%/31%). Items rated as most affected (= 4) were 'patient anxiety' (31%/51%), 'life not worthwhile' (26%/35%) and 'no self-worth' (19%/30%). Both groups indicated more problems solved 'particularly well' than 'inadequately'; the latter concerned mainly clinically well-known challenges during end-of-life care and family caregiver care.

CONCLUSIONS

This study shows the range and type of symptoms and other concerns reported in the patient's last days. Starting points for further improvements in family caregiver care and psychosocial and spiritual issues were identified.

Burden of disease assessment for Germany and its regions – results from the BURDEN 2020 study

Background

Epidemiological measures such as incidence, prevalence, or deaths are essential for monitoring population health. However, evaluating them in isolation cannot adequately compare and assess the relative importance of different diseases. Assessments of the burden of disease (BoD) are therefore of growing importance in supporting health policy decisions. Using disability-adjusted life years (DALY) as a summary measure of population health, BoD integrates morbidity and mortality in a transparent approach.

Methods

Within BoD methodology, deviations in the health of the population from an ‘ideal’ health status is quantified in the unit of life years. DALY are the sum of years of life lost due to death (YLL) and years lived with disability (YLD). While YLL describe the gap between age at death and statistical life expectancy, the indicator YLD quantifies years lived with a disability or disease. Calculations were based on different primary and secondary data sources for Germany, especially cause-of-death statistics, epidemiological survey data, and statutory health insurance data.

Results

In Germany, there were about 12 million DALY in 2017, the equivalent of 14,584 DALY per 100,000 population. Coronary heart disease contributes the most to the overall burden of disease, followed by lower back pain and lung cancer. In women, headache disorders and dementias account for more DALY as compared to men. Men have a higher burden of disease from lung cancer or alcohol use disorders. Pain disorders and alcohol use disorders lead the DALY rankings for both sexes in younger adulthood. The burden due to cardiovascular disease, COPD, and diabetes mellitus increases with age and also varies by region.

Conclusions

The results suggest age- and gender-specific prevention as well as regional health care needs. BoD studies therefore provide comprehensive data for population health surveillance and can support health policy decisions.

Key messages

• The importance of specific diseases as measured by DALY differs greatly by age and gender, highlighting the need for targeted prevention measures.

• Regional patterns emerge for cardiovascular disease, COPD, and depressive disorders, among others, which may indicate health care needs.

What are the personal last wishes of people with a life-limiting illness? Findings from a longitudinal observational study in specialist palliative care

Background

Personal last wishes of people facing a life-limiting illness may change closer to death and may vary across different forms of specialist palliative care (SPC).

Aims

To explore the presence and common themes of last wishes over time and according to the SPC settings (inpatient vs. home-based SPC), and to identify factors associated to having a last wish.

Methods

Patients enrolled in a longitudinal study completed questionnaires at the onset (baseline, t₀) and within the first 6 weeks (follow-up, t₁) of SPC including an open-ended question on their personal last wishes. Last wishes were content analyzed, and all  wishes were coded for presence or absence of each of the identified themes. Changes of last wishes (t₀-t₁) were analyzed by a McNemar test. The chi-square-test was used to compare the two SPC settings. Predictors for the presence of a last wish were identified by logistic regression analysis.

Results

Three hundred sixty-one patients (mean age, 69.5 years; 49% female) answered at t₀, and 130 at t₁. In cross-sectional analyses, the presence of last wishes was higher at t₀ (67%) than at t₁ (59%). Comparisons revealed a higher presence of last wishes among inpatients than those in home-based SPC at t₀ (78% vs. 62%; p = .002), but not at t₁. Inpatient SPC (OR = 1.987, p = .011) and greater physical symptom burden over the past week (OR = 1.168, p < .001) predicted presence of a last wish at t₀. Common themes of last wishes were Travel, Activities, Regaining health, Quality of life, Being with family and friends, Dying comfortably, Turn back time, and Taking care of final matters. The most frequent theme was Travel, at both t₀ (31%) and t₁ (39%). Themes did not differ between SPC settings, neither at t₀ nor at t₁. Longitudinal analyses (t₀-t₁) showed no significant intra-personal changes in the presence or any themes of last wishes over time.

Conclusions

In this late phase of their illness, many patients voiced last wishes. Our study suggests working with such wishes as a framework for person-centered care. Comparisons of SPC settings indicate that individualized approaches to patients’ last wishes, rather than setting-specific approaches, may be important.

Need for additional professional psychosocial and spiritual support in patients with advanced diseases in the course of specialist palliative care - a longitudinal observational study

BACKGROUND

We investigated the need for additional professional support and associated factors in patients (pts) at initiation and in the course of in- and outpatient specialist palliative care (I-SPC/O-SPC).

METHODS

Pts entering an urban SPC network consecutively completed questionnaires on psychosocial/spiritual problems and support needs within 72 h (T0) as well as within the first 6 weeks (T1) of SPC. Hierarchical linear regression analysis was used to investigate the impact of sociodemographic / disease-related variables, psychological / physical burden, social support, and SPC setting on the extent of support needs.

RESULTS

Four hundred twenty-five pts (70 years, 48% female, 91% cancer, 67% O-SPC) answered at T0, and 167 at T1. At T0, main problems related to transportation, usual activities, and dependency (83-89%). At T1, most prevalent problems also related to transportation and usual activities and additionally to light housework (82-86%). At T0, support needs were highest for transportation, light housework, and usual activities (35-41%). Cross-sectional comparisons of SPC settings revealed higher problem scores in O-SPC compared to I-SPC at T0 (p = .039), but not at T1. Support need scores were higher in O-SPC at T0 (p < .001), but lower at T1 (p = .039). Longitudinal analyses showed a decrease of support need scores over time, independent from the SPC setting. At T0, higher distress (p = .047), anxiety/depression (p < .001), physical symptom burden (p < .001) and I-SPC (p < .001) were associated with higher support need scores (at T1: only higher distress, p = .037).

CONCLUSION

Need for additional professional psychosocial/spiritual support was identified in up to 40% of pts. with higher need at the beginning of O-SPC than of I-SPC. During SPC, this need decreased in both settings, but got lower in O-SPC than in I-SPC over time. Support need scores were not only associated with psychological, but also physical burden.

Burden 2020: The German Burden of Disease Study Informative, comprehensive, appealing and digital: Providing health data to users. Accessibility of scientific results in the burden context

The aim of the BURDEN 2020 project is to calculate the Burden of Disease for Germany at the national and regional level. Based on the methods of the Global Burden of Disease study, the results will assess the impact of diseases on population health thus providing a freely accessible information basis for policy making and health care planning. How can the transfer from science to society take place on a low-threshold basis? We will talk about our strategy reaching out to decision-makers within health care planning in Germany and Europe. In addition, it will be examined how we wanted our results to be accessible, which possibilities of publication we choose beyond scientific articles and what options we had when talking about research marketing. We will also have a closer look on our demands for data visualization and transparency. In an ongoing process, two things were at stake: how do we define our target groups and how we address them. It has been proven to be a good strategy to continuously build up (international) networks, to share our knowledge and implement feedback. When publishing scientific results, it has turned out to be helpful for the project to approach a well-known bi-lingual journal with a wide range of coverage. We aimed to present the pilot project online with an appealing data visualization and graphic formats. This type of presentation made it easier to approach members of the press. Also, the inclusion of current topics such as COVID-19 helped to increase the media response. There are plans to include the use of the data in media formats such as webinars. Burden of Disease assessments can be challenging in implementation and communication. Before the start, the use of the metrics for Germany had to be thoroughly explained to national stakeholders. Within the project, we had to discuss how our data should be communicated to the public, to explain strength and weaknesses, and to produce publication formats that suit different target groups.

Excess costs of type 2 diabetes and their sociodemographic and clinical determinants: a cross-sectional study using data from the German Health Interview and Examination Survey for Adults (DEGS1)

OBJECTIVES

The objectives of this study were to estimate the direct and indirect excess costs of type 2 diabetes mellitus (T2D) using data representative for the German adult population and to investigate the association of sociodemographic and clinical determinants with these excess costs.

SETTING

We calculated mean annual costs for individuals with T2D and a control group without diabetes, using data on healthcare utilisation and productivity losses from the cross-sectional German Health Interview and Examination Survey for Adults. We adjusted for group differences using entropy balancing and estimated excess costs for total, direct, indirect costs and additional cost categories using generalised linear models. We performed subgroup analyses to investigate the association of sociodemographic (age, sex and education) and clinical determinants (diabetes duration, glycaemic index and complications) with excess costs.

PARTICIPANTS

The final study sample included n=325 individuals with T2D and n=4490 individuals without diabetes in the age between 18 and 79 years.

RESULTS

Total excess costs amounted to €927, of which €719 were attributable to direct and €209 to indirect excess costs. Total costs were significantly increased by 28% for T2D compared with controls. Group differences in direct, outpatient and medication costs were statistically significant. Medication costs were 88% higher for T2D and had the highest share in direct excess costs. With respect to specific determinants, direct excess costs ranged from €203 for 4-10 years diabetes duration to €1405 for diabetes complications. Indirect excess costs ranged from €-544 for >10 years diabetes duration to €995 for high education.

CONCLUSIONS

T2D was associated with high costs, mainly due to direct costs. As pointed out by our results, diabetes complications and comorbidities have a large impact on the costs, leaving medication costs as main contributor of T2D excess costs.

Why should gender-sensitive health reports be intersectional?

Background

A key focus of both epidemiology and PHMR is the identification of health inequity between population groups and its determinants. However, scholars in the social sciences have criticised prevalent approaches of describing health differences according to single social categories like sex/gender or race/ethnicity, glossing over significant heterogeneity within and relations between presumed population groups. Applying these critiques to the field of PHMR, we would argue that intersectionality scholarship offers vital impulses for the study of health inequity by focusing on several, interrelated social categories and emphasising the structural determinants affecting unique population subgroups differently.

Methods

We mapped existing approaches to describing population differences in health. We also conducted a literature review on intersectionality scholarship in public health and then synthesised results to develop a conceptual framework for deploying intersectionality to epidemiology and PHMR.

Findings

We identified four key principles through which the reporting on subgroup differences could be strengthened: addressing the internal heterogeneity of population groups; contextualising inequities and focusing on societal power relations rather than individual characteristics; deploying novel multivariable modelling approaches in data analysis; and aiming towards the empowerment of population groups rather than deploying deficit-oriented and paternalistic models.

Discussion

To be discussed are the unique contributions of intersectionality to PHMR compared to other approaches, for example from social epidemiology or medical anthropology.

Suggestions for a gender-sensitive and intersectional practice of health monitoring and reporting

Background

Health reports summarize the evidence basis on disease burden and its causes and are intended to inform decisions of policy makers. By focusing on health needs of social groupings according to sex/gender or race/ethnicity, PHMR crucially contributes to achieving health equity. In order to realise its aims, PHMR relies on the availability of high-quality data, appropriate analysis methods and intuitive presentation of results.

Methods

The joint project AdvanceGender used mixed methods to translate principles of intersectionality into new methods for recruitment, data analysis and health reporting. A review of descriptions of representativeness in epidemiological studies was conducted to investigate how an intersectional perspective can inform recruitment. To evaluate intersectional and gender-sensitive data analysis, we reviewed and applied recently developed methods such as classification and regression tree analysis (CART) and multilevel analysis of individual heterogeneity and discriminatory accuracy (MAIHDA).

Findings

An intersectional perspective on representativeness unravelled that study participation of women and men might be differential according to further social categories such as civil status or educational level. CART analysis might help to identify intersectional groupings differing in health behaviours or outcomes by exploring a multitude of social dimensions without facing the risk of stereotyping with predefined categories. MAIHDA depicts an alternative method that is suited for descriptive analyses of health-related outcomes among intersectional strata. In contrast to analysing supposedly static features such as sex, a focus on solution-linked variables like social support might be a fertile ground to identify areas for public health action.

Discussion

Principles of intersectionality open up new perspectives for recruitment and data analysis that might be fruitful for population health research and ultimately for PHMR.

Determinants of frequent use of primary care in the German healthcare system

Background

In Germany, patients are consulting general practitioners increasingly frequently, resulting in a high burden on the healthcare system. This study aimed to identify factors associated with frequent primary care attendance in the German healthcare system.

Methods

The German Health Interview and Examination Survey for Adults (DEGS) is part of Germany’s national health monitoring, and includes a large representative sample of the German population aged 18-79 years. We defined the 10% of participants with the highest number of physician contacts in the preceding 12 months as frequent attenders. Binary logistic regression models with average marginal effects were used to identify determinants for the frequent use of primary care services.

Results

The sample comprised 7,956 participants. Significant effects on frequent use of primary care were observed for low socioeconomic status, stressful life events, and factors related to objective need for medical care and subjective health status. In the full model, the number of non-communicable diseases and subjective health status had the strongest effect on frequent primary care use. We found an interaction effect between subjective health status and number of non-communicable diseases, indicating the association of disease with frequent use was highly moderated by subjective perception of health.

Conclusions

We observed strong associations between frequent primary care attendance and objective and subjective health-related factors. These findings suggest that better coordination of care may be a preferred method to manage health services utilization behaviour and avoid redundant examinations and uncoordinated clinical pathways. Further research is needed to clarify moderating and mediating factors contributing to high utilization of primary care services.

Key messages

The number of NCDs diseases and subjective health had the strongest effect on frequent primary care use. The findings suggest that better coordination of care may be the preferred method to manage health services utilization.

Health of adolescents with migration background in Germany: cross-sectional results from KiGGS wave 2

Background

Although 36.5% of minors in Germany had a migration background (MB) in 2017, data on their health situation is scarce. The project ‘Improving Health Monitoring in Migrant Populations’ (IMIRA) initiated in 2016 aims to expand health reporting on the health situation of people with MB, for which a core indicator set was developed. We are describing the health situation of adolescents based on selected core indicators.

Methods

Data from the German Health Interview and Examination Survey for Children and Adolescents (KiGGS wave 2) (2014-2017) are used; adolescents from 11 to 17 years are considered. Prevalences and 95% confidence intervals are calculated for the following indicators: General health status, overweight, hazardous alcohol consumption and use of pediatric or general practitioner’s services. These indicators are stratified along socio-demographic (gender, age, socio-economic status (SES)) and migration-related characteristics (MB, parents’ duration of stay, language spoken at home).

Results

There are hardly any migration-related differences in the general health status and the use of general medical services. While adolescents with MB are more often affected by overweight (without MB: 11.2%, one-sided: 18.9%, both-sided: 19.8%), they show less often risky alcohol consumption (without MB: 14.5%, one-sided: 7.8%, both-sided: 4.4%). There are differences in health behavior according to SES, parents’ duration of stay in Germany and language spoken at home.

Conclusions

Overall, the health of adolescents is good, regardless of their MB, and general medical services are used equally. Differences in health behavior cannot be reduced solely to the (non-)existence of a MB, but need a deeper consideration of more specific migration-related characteristics and the SES.

Key messages

The general health status and health care utilization do not differ between adolescents with and without MB. In contrast, the results on indicators of health behavior vary.

[Frequency of falls among clients of home care services : The importance of care-related and social risk factors]

BACKGROUND

Among the elderly falls frequently result in injuries, increase the need for long-term care and pose a challenge for the quality assurance in nursing care. We describe the frequency and risk factors of falls among care-dependent persons using home care services in Germany.

METHODS

The participants of the study "Nursing-related health problems in home care" (n = 880) were recruited based on a list of the officially accredited nursing services. Data collection followed a standardized study protocol. Proportions were calculated and adjusted odds ratios and predicted probabilities were estimated using binary logistic regression.

RESULTS

Falls are a frequent occurrence among care-dependent persons who are cared for by home care services: Almost every tenth care-dependent person suffers from a fall within a period of 2 weeks. Falls are mainly associated with social and care-related factors. Besides a low educational status this comprises certain living and care arrangements: People living alone or having infrequent contact to their nursing service as well as clients that, according to their carers, should receive more support have a significantly higher chance of falling. Multimorbidity is a medical risk factor while neurological diseases as well as polypharmacy present increased risks only in interaction with living and care arrangements.

CONCLUSION

Nursing staff and physicians should maintain an overview of the social and health conditions of people in need of long-term care. If care-dependent persons live alone or are infrequently cared for, additional medical problems considerably increase the risk for falling; therefore, preventive interventions and follow-up assessments of actual need levels should be promptly considered if health conditions or living arrangements change.

[Participation of people with migration background in health surveys of the Robert Koch Institute]

People with migration background (PMB) make up a huge section of the population with specific health chances and risks. There are only limited data available on the health situation of PMB, since inclusion of PMB in surveys is hindered, e.g. due to language barriers. The present study has examined to what extent the population-based health surveys of the Robert Koch Institute have managed to include a representative extent of PMB, with the aim of deriving recommendations for analysis options and future recruitment strategies. The 2009 microcensus (MC) of the Federal Statistical Office was used as the basis to check whether the sample of KiGGS Wave 1 (2009-2012) and DEGS 1 (2008-2011) are representative regarding socio-demographic and migrant-specific characteristics. 1107 PMB participated in DEGS 1. In comparison to the MC, particular sub-groups are underrepresented in the sample: people who immigrated themselves (first-generation migrants), people with a low education and Turkish citizens. On the other hand, some age groups are overrepresented. In KiGGS Wave 1, 2021 children and adolescents with a migration background participated. Response was lower if parents had a low education. In total, the participation of children and adolescents with a migration background was lower in comparison to the KiGGS baseline survey. The data on PMB in DEGS 1 and KiGGS Wave 1 are appropriate for health analyses of this population group. However, analyses should be stratified according to characteristics like migrant generation, age or education level, or these characteristics should be adjusted for in statistical models. In order to achieve a representative inclusion of people with a migration background, in future surveys sub-group-specific activities to increase participation of PMB are recommended.

A Consensus German Reporting Standard for Secondary Data Analyses, Version 2 (STROSA-STandardisierte BerichtsROutine für SekundärdatenAnalysen)

Although secondary data analyses have been established in recent years in health research, explicit recommendations for standardized, transparent and complete reporting of secondary data analyses do not exist as yet. Therefore, between 2009 and 2014, a first proposal for a specific reporting standard for secondary data analysis was developed (STROSA 1). Parallel to this national process in Germany, an international reporting standard for routine data analysis was initiated in 2013 (RECORD). Nevertheless, because of the specific characteristics of the German health care system as well as specific data protection requirements, the need for a specific German reporting standard for secondary data analyses became evident. Therefore, STROSA was revised and tested by a task force of 15 experts from the working group Collection and Use of Secondary Data (AGENS) of the German Society for Social Medicine and Prevention (DGSMP) and the German Society for Epidemiology (DGEpi) as well as from the working group Validation and Linkage of Secondary Data of the German Network for Health Services Research (DNVF). The consensus STROSA-2 checklist includes 27 criteria, which should be met in the reporting of secondary data analysis from Germany. The criteria have been illustrated and clarified with specific explanations and examples of good practice. The STROSA reporting standard aims at stimulating a wider scientific discussion on the practicability and completeness of the checklist. After further discussions and possibly resulting modifications, STROSA shall be implemented as a reporting standard for secondary data analyses from Germany. This will guarantee standardized and complete information on secondary data analyses enabling assessment of their internal and external validity.

[Utilization of Physiotherapy Services by Children and Adolescents - Results of the KiGGS- Baseline Survey]

Aim of the study: The use of physical therapy in German children and adolescents has so far solely been analyzed on the basis of health insurance data, which can neither consider case history nor social factors. Using the KiGGS-baseline survey it is possible to examine the use of physical therapy on the basis of parental reported health problems and social factors. Methodology: Identifiable determinants for the use of physical therapy in the last 12 months in the KiGGS-baseline survey were examined bivariate and multivariate in logistic regression models with mutual adjustment. The following determinants were considered: social factors, somatic disorders and psychological abnormalities. The proportion of the use of physical therapy, which can be explained by these determinants, was estimated using population-attributable risk fraction. Results: The frequency of the use of physical therapy in the last 12 months in the 0 to 17-year-olds in the KiGGS-baseline survey was 6,4% with higher use during infancy and adolescence. The socio-economic status of parents was not associated with the use of physical therapy. A migration background decreased the probability of the use of physical therapy, for example, among children aged 0 to 2 years (OR_adjusted: 0,5 [95% CI: 0,2-1,0]). In those with scoliosis, the use of physical therapy was almost twice as frequent in infancy as in adolescence (58,4 vs. 34,4%). A maximum of 15% of all children and adolescents with back pain reported the use of physical therapy. When ADHD was diagnosed at preschool age, the probability of using physical therapy was increased (OR_adjusted: 5,1 [95% CI: 1,4-18,6]). The health problems, which were assessed in the KiGGS-baseline survey and considered for this analysis could explain 37% of the use of physical therapy in the 0 to 2-year-olds. In the other age groups, 59 to 62% could be explained. Conclusion: Comparison of the KiGGS-baseline survey with health insurance data shows similar frequencies and patterns of the use of physical therapy and can therefore be used for the analysis of healthcare questions on the use of physical therapy. The data point to potential deficits in treatment in population segments and for some conditions. An examination of these hypotheses based on analyses of health insurance data seems to be reasonable.

[Unintentional injuries in childhood and adolescence: current prevalence, determinants, and trends: results of the KiGGS study: first follow-up (KiGGS Wave 1)]

BACKGROUND

In Germany and worldwide, unintentional injuries (UI) are a major health threat for children and adolescents. The first follow-up of the German Health Interview and Examination Survey for Children and Adolescents (KiGGS Wave 1, 2009-2012) continued the national UI monitoring that started with the KiGGS baseline study (2003-2006). The present analysis provides updated information and for the first time gives indications on time trends.

METHODS

KiGGS Wave 1 is a combined nationwide cross-sectional and longitudinal survey by the Robert Koch Institute (RKI) providing information about 12,368 participating children and adolescents (0-17 years old; response rates: 38.8% first time invited, 72.9% reinvited). Parents were asked about their children's UI and poisonings via telephone interviews. Information on UI is available for 11,665 children and adolescents (1-17 years old). The 12-month prevalence rate and 95% confidence interval were calculated, and KiGGS Wave 1 was compared with the KiGGS baseline study. The Rao-Scott chi-square test corrected over the F distribution was used to test for the statistical significance of subgroup differences and trend effects.

RESULTS

Within the previous 12 months, 15.5% of all children and adolescents aged 1-17 years were medically treated for UI. UI were significantly more prevalent among boys (17.0%) than among girls (14.0%), and 3.4% of the subjects had more than one accident leading to UI. One in eight children and adolescents who suffered UI stayed in hospital (12.3%) for inpatient treatment for at least one night. The home, childcare and educational institutions, and sports facilities/playgrounds were the predominant accident locations. Compared to the baseline study, neither the overall prevalence of UI nor the gender- and age-specific patterns changed significantly.

CONCLUSION

Since a large proportion of UI is avoidable, knowledge of high-risk subgroups and accident locations is of particular use for prevention. KiGGS Wave 1 makes an important contribution to the comprehension of these issues. The transfer of research into practice is of particular importance for the avoidance of UI.

[Unintentional injuries among children and adolescents in Germany. Data sources and results]

Compared to adults, children and adolescents run a considerably higher risk of suffering unintentional injuries (UI). To prevent UI, detailed knowledge of the overall accident occurrence and the determinants of UI is needed. This article gives an overview of the data sources covering the occurrence of UI among children and adolescents in Germany. According to the Robert Koch Institute's German Health Interview and Examination Survey for Children and Adolescents (KiGGS), approximately 15.3 % of children and adolescents (1-17 years) in Germany suffer at least one UI within 12 months. Most accidents (60.7 %) occur at home or during leisure-time activities. In 2011, the German Statutory Accident Insurance (DGUV) registered more than 1.4 million accidents among children in day-care facilities and students in educational institutions. According to official statistics, in the same year, more than 50,000 children and adolescents were injured in traffic accidents. Moreover, the Federal Statistical Office registered 260,534 hospital admissions due to injuries and poisonings among children and adolescents. All data sources revealed age- and sex-specific differences. Boys suffer UI more frequently than girls do and they show higher injury rates in adolescence than during childhood. While UI among children mostly happen at home, road traffic and leisure-time accidents increase in occurrence during adolescence. In Germany, there are numerous initiatives dedicated to the prevention of UI in children and adolescents. The creation of target group-specific prevention measures is complicated by the fact that the methodological approaches of existing data sources differ considerably.

[Unintentional injuries in the German adult population. Results of the "German Health Update" survey 2010]

In Germany, more than 20,000 people were killed in accidents and 8.7 million people suffered nonfatal unintentional injuries (UI) in 2011. This report gives an overview of the occurrence of nonfatal UI in the German adult population. The representative health survey "German Health Update" 2010 (phone survey) collected data on nonfatal accidents in the adult population within a recall period of 12 months (n = 22,050). Interviewees reporting medically treated UI responded to 19 further questions about accident locations, accident mechanisms, injuries, and consequences of up to three UI within 1 year. Overall, detailed data on 2,117 UI were collected. About 7.9 % of the German adult population suffers at least one medically treated UI within 1 year. Men are more often affected than women and young people more frequently than older people. The majority of all UI occurs at home or during leisure-time activities. One in five UI results from accidents on public footways, roads, and squares. Falls account for almost every third UI and about one in five accidents causes fractures. Two thirds of all UI require inpatient treatment. Two in three UI lead to temporary sick leave averaging 29.7 days of absenteeism. Among UI at home and in leisure-time activities, falls have particularly serious consequences. Moreover, falls play an important role in UI among pedestrians and cyclists. UI affect large parts of the German adult population and are clearly patterned by gender, age, and accident location. Therefore, prevention activities should consider target group-specific needs and setting-specific circumstances of UI.

Gesundheitsmonitoring der Migrationsbevölkerung in der Schweiz

With the health monitoring of the Swiss migrant population, a database was created on migrants' health state, their health behaviour and utilization of health services. Thanks to this database, it is now possible to draw representative conclusions on the health status of migrants compared to the indigenous population. Based on the Swiss Health Survey, a questionnaire was developed and translated into several languages. A survey of the foreign population permanently resident in Switzerland as well as of asylum seekers and those temporarily settled in Switzerland was conducted through phone interviews. The interviewees could choose the survey language: in their mother tongue or one of the Swiss languages. A first description of the data is available. The analyses show that the results found for migrants of West European countries are comparable to those of the Swiss population. All other migrants come off worse with regard to health and social indicators. For example, they assess their self-perceived health state more often as "average" or "bad", they feel emotionally less balanced, or visit a doctor more frequently than the Swiss population does. Significant differences can be found within the data of the surveyed migrant population, for example depending on gender, age, residence status or nationality.

[Migration and rehabilitation of mental diseases -- perspectives and limitations in the reporting of official data of service providers]

Health and social monitoring are important foundations of political decision making. In order to make statements about populations and subgroups different sources of information are generally used. The potential contribution which aggregated official health data of service providers can make is discussed in the exemplary context of the utilisation of medical rehabilitation of mental diseases. Age specific rates and age standardised ratios show a significantly increased utilisation of services for depression and somatoform disorders amongst women in general and the migrant population in particular. It is demonstrated that the interpretation of such results raises new research questions rather than providing explanations that could prove to be conducive for practical measures. In a methodological discussion it is stated that the reason for this has to be seen in the fact that important structures of action within the care system are concealed by the specific method of collecting and processing official health data. Nevertheless, conceivable interpretations are given regarding the psycho-social living conditions of large parts of the migrant population as well as their difficulties in the interaction with the medical system. This enables the formulation of a hypothetical framework for further research which could help to clarify statistical phenomena found in the official data of service providers.

[Incidence of pathologic ammonia concentrations in the plasma in children with seizure disorders treated with Convulsofin/Convulex and other anticonvulsants in comparison with children with brain damage and healthy children]

In healthy children plasma ammonia concentrations show values from 12.3 to 57.2 mumol/l (80%-range) (group I). We also measured plasma ammonia in epilepsy patients with valproate therapy (group II) and epilepsy patients treated with other anticonvulsiva (group III). In a fourth group there were children with various cerebral lesions without episodes and without anticonvulsiva therapy. There were significant differences between group I and group II and group II and group IV respectively. But no significant differences were found between the patients who were treated with valproate and the patients with cerebral lesions. The data does not allow the plasma ammonia concentration to be taken as a control parameter in children treated with valproate. Ammonia estimation at the beginning of therapy, however, may be used as risk indicator.

Thalidomide neuropathy: an electrophysiologic study

Thalidomide is effective in the treatment of such disabling dermatologic diseases as aphthosis, discoid lupus erythematosus, and prurigo nodularis, in which other drugs fail. However, its use can induce neuropathy necessitating caution in its administration. It was found in this electrophysiologic study of 13 patients that the data best revealing neuropathy, even when clinical abnormalities were not apparent, were reduction of sensory nerve action potential amplitude on the sural nerve, increase of somatosensory evoked potential latency following sural nerve stimulation, and reduction of sensory action potential amplitude on stimulating the median nerve at the wrist. In two patients, electrophysiologic abnormalities had increased after withdrawal, suggesting a prolonged action of thalidomide. Timely reduction of dosage, after detection of changes indicating the onset of side effects, could reduce the risk of the sometimes rapid emergence of clinical symptoms.

Pharmacokinetics and pharmacodynamics of pentopril, a new angiotensin-converting-enzyme inhibitor in humans

In a single, ascending-dose tolerance study, nine healthy volunteers were given oral pentopril 50 to 750 mg (CGS 13945) in groups of three each. Disposition characteristics of pentopril and its active metabolite (CGS 13934) were determined using plasma concentration and urinary excretion data. The drug was absorbed rapidly following zero-order kinetics. The drug has an apparent volume of distribution of 0.83 L/kg and an oral clearance of about 0.79 L/hr/kg. Urinary excretions, calculated after 125- and 250-mg doses, showed a dose proportional urinary recovery of 21% (+/- 5%) for pentopril and 40% (+/- 5%) for CGS 13934. In the multiple-dose study of 125 mg orally q12h in six healthy subjects, the plasma concentrations for both drug and metabolite showed no appreciable accumulation of either compound, which was expected from their short pharmacokinetic half-lives (pentopril, less than 1 hr; CGS 13934, approximately 2 hr). In a separate pharmacodynamic study, drug and metabolite concentrations were evaluated against angiotensin-I (AI)-induced changes in blood pressure and plasma angiotensin-converting-enzyme (ACE) activity in healthy volunteers after single oral doses (range, 10-500 mg). The pharmacodynamic half-life for plasma ACE inhibition increased with the dose (10 mg, 1.5 hr; 500 mg, 9.8 hr). There was a close relationship between the plasma level of the metabolite and the inhibition of plasma ACE activity and AI-induced pressor response. A hyperbolic function adequately described the dependence of plasma ACE activity on plasma metabolite concentration with a concentration at half-maximal inhibition of 53 ng/mL.

Effect of food on the bioavailability of pentopril, an angiotensin-converting-enzyme inhibitor, in healthy subjects

Pentopril (CGS 13945) was administered in 125-mg capsules to eight healthy men on two occasions according to a randomized schedule; on one occasion in the fasting state and on the other occasion immediately following the ingestion of a standardized meal. Unlike captopril, a prototype angiotensin-converting-enzyme inhibitor, there was no significant difference in the peak plasma concentration for either the drug or its active metabolite (CGS 13934) between the fasting and the fed states. There was also no appreciable change in the area under the plasma curve for the drug and its metabolite after administration of drug in the presence of food compared with a fasting state. There was, however, a lag time in drug absorption after ingestion of food, which resulted in a significant increase in peak time for the active metabolite in plasma. Food delays the body's absorption of the drug and hence the appearance of its active metabolite in plasma without any significant effect on the relative bioavailability. Because relative bioavailability is not affected in the presence of food, such a delay may not have any therapeutic importance on chronic administration.
