Today the medical community faces a number of pressing issues. Molecular and high-tech medicine, despite their tremendous successes, also burden us with new ethical dilemmas: when and how to die, whose life to preserve, whether to modify genes and to create life, and how to pay for it all. Furthermore, alternative methods appear to work at least for certain disorders. They are popular and definitely cost less, while the spiraling costs of conventional medicine have led to the development of managed care and health economy assessments with controversial consequences. An international symposium in Berlin, in September 1999, sought to address some of these issues by sparking an interdisciplinary discussion gathering leading experts in the field of genetics, robotic surgery, medical ethics, preventive health and health economics, history, and law. This book contains all the contributions and seeks to involve scholars and medical practitioners who are interested in shaping the future of medicine

BACKGROUND In 1920, the physician Alfred Grotjahn was appointed as first Chair for Social Hygiene in Germany at the University of Berlin. During reign of national socialism, the Institute for Social Hygiene was closed and from 1933 and 1945 transformed into an Institute for Racial Hygiene. During that period, many German scientists including social medicine co-workers of the Berlin Charité emigrated due to political, religious or racial prosecution. METHODS The basis for this biographical presentation of co-workers of Grotjahn, who emigrated to the USA, is based on research conducted at German and American sources such as the Archive of Humboldt University of Berlin, Federal Archive in Koblenz, National Institutes of Health in Washington, NARA Archive in Washington, and Alan-Mason-Chesney Medical Archives in Baltimore. RESULTS The Jewish scientists Franz Goldmann, Miron Kantorowicz, Alfred Korach and Georg Wollf, all former co-workers of Alfred Grotjahn, were forced to leave the country in the 30s and emigrated to the USA. They were active in different areas of public health and pursued relatively successful careers. DISCUSSION The societal system and mentality of the USA have obviously profited from the professional background and experience arising from the emigration of former social medicine experts of the Charité. ; Hintergrund: Der Arzt Alfred Grotjahn wurde 1920 an der Universität Berlin auf den ersten Lehrstuhl für Sozialhygiene in Deutschland berufen. In der Zeit des Nationalsozialismus wurde das Institut für Sozialhygiene geschlossen bzw. von 1933 bis 1945 in ein Institut für Rassenhygiene umgewandelt. In dieser Zeit emigrierten viele deutsche Wissenschaftler aufgrund politischer, religiöser oder rassischer Verfolgung, so auch Sozialmediziner der Berliner Charité. Methodik: Basis dieser biographischen Darstellung von Schülern Grotjahns, die in die USA emigrierten, sind Nachforschungen in deutschen sowie amerikanischen Quellen, u.a. Archiv der Humboldt-Universität Berlin, Bundesarchiv in Koblenz, ...
Aim: The neighbourhood environment appears to influence people's food consumption. Access, variety and pricing of foods play a role in the socioeconomic difference of fruit and vegetable consumption. This study compared differences in the number of grocery stores, variety of fresh fruits and vegetables, and food prices in districts with different Social Indices (SI) in Berlin, Germany. Methods: The district with the lowest SIs was compared to the district with the highest SI. The number of grocery stores offering fresh produce, the variety of fresh fruits and vegetables, and prices of selected healthy and less healthy food items were assessed and compared. Results: The low SI district had more grocery stores per residents than the high SI district. Variety and prices of fruits and vegetables did not differ between the two districts, but milk and whole wheat bread were less expensive in the high SI district. For all grocery stores, selected foods with higher energy density had lower energy costs than low energy density foods. Conclusion: Health inequalities in Germany might be less influenced by access to healthy foods than in other countries, but nutrient-rich foods such as fruits and vegetables have higher energy costs than high energy dense foods.
Background and objectives: An important component of efficient and high-quality treatment of patients under DRG conditions is the control of patients' length of stay in hospitals. Medical processes need to be structured in such a way that unnecessary extensions of the length of stay are avoided, thus achieving an economically and qualitatively optimal result. The study presented here examines the question of whether the introduction of length-of-stay-oriented case management can optimize the duration of patients' hospital stays. Methods: In total, 168 inpatient cases and their matched control cases from the cardiology and urology stations of a maximum care hospital are examined in this study. Results: The result of the t-test for the difference of means indicates that the average length of stay of the intervention cases (5.79 days) was significantly shorter than the average length of stay of the control cases (7.34 days). With respect to the re-admission rate, a statistically significant dependence could not be determined. Discussion and conclusion: The operationalization of case management in daily clinical routines was tested by a comprehensive survey. Length-of-stay-oriented case management provides transparency of the entire treatment process and integrates procedures to an optimal extent. However, the doctor's sovereignty over therapy is not affected by the introduction of length-of-stay-oriented case management. Hence, the form of case management presented here serves as a new and innovative control and monitoring system for hospitals, as it makes institutions that implement such a system more competitive through the improvement of economical aspects as well as through the introduction of higher process efficiency.
Background: Health economic parameters are increasingly considered as variables in health care decisions, but decision makers are interested in country-specific evaluations. However, a large number of studies are performed in foreign countries or in a multinational setting, which limits the transferability to a single nation's context. Objective: The present analysis summarises several of the most common international methods for generating health economic analyses based on clinical studies from different settings. Methods: A narrative literature review was performed to identify potential reasons for limited transferability of health economic evaluation results from one country to another. Based on these results, we searched the methodological literature for analytic approaches to handle the restrictions. Additionally we describe the possibility of transferring foreign economic study results to the country of interest by matching trial data with routine data of national databases. Results: The main factors for limited transferability of health economic findings were found in country-specific differences in resource consumption and the resulting costs. These differences are affected by a number of influencing cofactors (demography, epidemiology and individual patient's factors) and the overall health care system structures (e.g. payment systems, health provider incentives). However, despite the limitations country-specific health economic assessments could be realised using the pooled/ split analyses approach, some statistical approaches and modelling approaches. Conclusion: A variety of methods for identifying and adjusting country-specific differences in costs, effects and cost-effectiveness was established during the past decades. Multinational studies will continue to play a crucial role in the evaluation of cost-effectiveness at national levels. It seems likely that the growing interest in multinational studies will lead to continued developments in adaptation methods.
BACKGROUND: Web portals providing health information online have the potential to reach large numbers of people. Yet few studies have assessed usage and costs of health portals, especially over an extended period of time. OBJECTIVES: First, to assess the usage of a web portal on prevention and health promotion that was initiated by the German states of Berlin and Brandenburg. Second, to estimate average cost per pageview over the full web portal life-cycle. METHODS: Usage data were gathered through Google Analytics. The main usage metric assessed was pageviews originating from an IP address in Berlin or Brandenburg. Project cost data were reported by the local government and from own records. Descriptive and regression analyses were used to determine time trends in pageviews. RESULTS: The redesigned web portal Praeventionsatlas.de launched August 2011 and was discontinued March 2018. Analyzing the full calendar years only, the annual pageview number increased from 2012 (8492) to its peak in 2014 (11,876) and steadily decreased to its minimum in 2017 (7232). Pages of the web portal were most often viewed around lunchtime (12 to 1 p.m.), in the middle of the week (Wed to Thu), and at the beginning of the year (Jan to Feb). Adjusting for year, month, and weekday, the number of daily pageviews dropped on major public holidays (Easter −9, Pentecost −12, Christmas −12 and New Year's Eve and Day −20; p < .001) and increased during the fasting period before Easter (+6; p < .001). Average cost per page viewed from relaunch until the web portal went offline was estimated to be €0.38 (€0.33 to €1.67) per pageview. CONCLUSION: Usage of the web portal showed temporal variation and peaked before the middle of its 6.5 year life-cycle. Development and need for updates may require substantial investment in a web portal, such that a pageview can come at a considerable expense, even in small-scale projects. Assessing and discussing the cost-effectiveness of a web portal is therefore desirable.
Einleitung: In Deutschland leiden derzeit etwa eine Million Menschen an einer Demenzerkrankung. Aufgrund der demografischen Entwicklung ist mit einem deutlichen Anstieg der Häufigkeit solcher Erkrankungen in den kommenden Jahren zu rechnen. Demenz ist in höherem Alter die häufigste Ursache von Pflegebedürftigkeit. Da diese Krankheiten in der Regel nicht heilbar sind, liegt der Fokus der Pflege auf der Verzögerung des Voranschreitens der Erkrankung sowie der Aufrechterhaltung von Funktionsfähigkeit und Lebensqualität der Betroffenen. Fragestellung: Wie ist die Evidenz für pflegerische Konzepte für Patienten mit Demenz hinsichtlich gebräuchlicher Endpunkte wie kognitive Funktionsfähigkeit, Fähigkeit zur Durchführung von Aktivitäten des täglichen Lebens, Lebensqualität, Sozialverhalten? Wie ist die Kosten-Effektivität der betrachteten Pflegekonzepte zu bewerten? Welche ethischen, sozialen oder juristischen Aspekte werden in diesem Kontext diskutiert? Methoden: Auf Basis einer systematischen Literaturrecherche werden randomisierte kontrollierte Studien (RCT) mit mindestens 30 Teilnehmern zu folgenden Pflegekonzepten eingeschlossen: Validation/emotionsorientierte Pflege, Ergotherapie, sensorische Stimulation, Entspannungsverfahren, Realitätsorientierung und Reminiszenz. Die Studien müssen ab 1997 (für den ökonomischen Teil ab 1990) in deutscher oder englischer Sprache publiziert worden sein. Ergebnisse: Insgesamt 20 Studien erfüllen die Einschlusskriterien. Davon befassen sich drei Studien mit der Validation/emotionsorientierte Pflege, fünf Studien mit der Ergotherapie, sieben Studien mit verschiedenen Varianten sensorischer Stimulation, je zwei Studien mit der Realitätsorientierung und der Reminiszenz und eine Studie mit einem Entspannungsverfahren. Keine signifikanten Unterschiede zwischen Interventions- und Kontrollgruppe berichten zwei von drei Studien zur Validation/emotionsorientierten Pflege, zwei von fünf Studien zur Ergotherapie, drei von sieben Studien zur sensorischen Stimulation, beide Studien zur Reminiszenz, und die Studie zur Entspannung. Von den verbleibenden zehn Studien berichten sieben teilweise positive Ergebnisse zugunsten der Intervention und drei Studien (Ergotherapie, Aromatherapie, Musik/Massage) berichten positive Effekte der Intervention hinsichtlich aller erhobenen Zielkriterien. Sechs Publikationen berichten ökonomische Ergebnisse von Pflegemaßnahmen. Eine Studie berichtet Zusatzkosten von 16 GBP (24,03 Euro (2006)) pro Patient pro Woche für Beschäftigungstherapie. Zwei weitere Veröffentlichungen geben inkrementelle Kosten von 24,30 USD (25,62 Euro (2006)) pro gewonnenen Mini-mental-state-examination-(MMSE)-Punkt pro Monat bzw. 1.380.000 ITL (506,21 Euro (2006)) pro gewonnenen MMSE-Punkt an. Zwei Publikationen berichten über Mischinterventionen, wobei einmal die Zusatzkosten für ein Aktivitätsprogramm (1,13 USD (1,39 Euro (2006)) pro Tag pro Pflegebedürftigem) und einmal der zeitliche Mehraufwand für die Betreuung mobiler Demenzpatienten (durchschnittlich 45 Minuten zusätzliche Pflegezeit pro Tag) berichtet wird. Hinsichtlich ethisch-sozialer Aspekte wird vor allem die Selbstbestimmung von Demenzpatienten diskutiert. Aus einer Demenzdiagnose lässt sich danach nicht zwingend schließen, dass die Betroffenen nicht eigenständig über eine Studienteilnahme entscheiden können. Im juristischen Bereich versucht die Regierung mit dem Pflege-Weiterentwicklungsgesetz (PfWG) die finanzielle Lage und die Betreuung der Pflegenden und Gepflegten zu verbessern. Weitere Fragestellungen rechtlicher Natur betreffen die Geschäftsfähigkeit bzw. die rechtliche Vertretung sowie die Deliktfähigkeit von an Demenz erkrankten Personen. Diskussion: Es gibt nur wenige methodisch angemessene Studien zu den in diesem Bericht berücksichtigten pflegerischen Konzepten für Demenzkranke. Die Studien haben überwiegend kleine Fallzahlen, und weisen erhebliche methodische Unterschiede hinsichtlich der Einschlusskriterien, der Durchführung, und der erfassten Zielkriterien auf. Diese Heterogenität zeigt sich auch in den Ergebnissen: in der Hälfte der eingeschlossen Studien gibt es keine positiven Effekte der Intervention im Vergleich zur Kontrollgruppe. Die andere Hälfte der Studien berichtet zum Teil positive Effekte bezüglicher unterschiedlicher Zielkriterien. Die ökonomischen Studien sind methodisch und thematisch nicht dazu geeignet die aufgeworfenen Fragestellungen zu beantworten. Ethische, soziale und juristische Aspekte werden diskutiert, aber nicht systematisch im Rahmen von Studien erfasst. Schlussfolgerung: Basierend auf der derzeitigen Studienlage liegt für keines der untersuchten Pflegekonzepte ausreichende Evidenz vor. Fehlende Evdienz bedeutet in diesem Kontext jedoch nicht zwingend fehlende Wirksamkeit. Vielmehr sind weitere Studien zu diesem Thema notwendig. Wünschenswert wären insbesondere Studien, die in Deutschland unter den Rahmenbedingungen des hiesigen Ausbildungs- und Pflegesystems durchgeführt werden. Dies gilt auch für die gesundheitsökonomische Bewertung der Pflege ; Introduction: Today there are approximately one million people with dementia in Germany. If current demographic trends continue, this number is likely to rise substantially in the coming years. In the older population, dementia is the most frequent reason for long-term care. Because most forms of dementia cannot be cured, the aim of treatment is to delay disease progression and to maintain functioning and quality of life. Research questions: What is the evidence on different approaches to the long-term usual care of patients with dementia in terms of common endpoints such as quality of life, and social behaviour? How is the cost-effectiveness of these concepts to be evaluated? Which ethical, social, or legal issues are discussed in this context? Methods: Based on a systematic literature review, we include randomized, controlled studies that had at least 30 participants and investigated one or more of the following approaches of dementia care: validation therapy/emotion-oriented usual care, ergotherapy, sensory stimulation, relaxation techniques, reality orientation therapy, and reminiscence therapy. Studies had to be published after 1996 (after 1990 for the economic part) in English or German. Results: A total of 20 studies meet the inclusion criteria. Of these, three focus on validation therapy/emotion-oriented usual care, five on ergotherapy, seven on different kinds of sensory stimulation, two on reality orientation, two on reminiscence therapy, and one on a type of relaxation technique. There are no significant differences between the intervention and control groups in two of the three studies on validation therapy or emotion-oriented usual care, in two of the five studies on ergotherapy, in three of the seven studies on sensory stimulation, in both of the two studies on reminiscence therapy, and in the one study on relaxation. In the remaining ten studies, seven report some positive results in favour of the respective interventions, and three studies (ergotherapy, aroma therapy, and music/massage) report positive effects with respect to all of the endpoints measured. Six publications present economic results for usual-care-concepts. One study reports additional costs of 16 GBP (24.03 Euro (2006)) per patient per week for occupational therapie. Two publications declare incremental cost of 24.30 USD (25.62 Euro (2006)) per mini-mental-state-examination-(MMSE)-point gained per month respectively 1,380,000 ITL (506.21 Euro (2006)) per MMSE-point gained. Two publications focus on mixed interventions. One study reports the additional costs of an activity program (1.13 USD (1.39 Euro (2006)) per day per patient) and the other additional time for the usual care for mobile demented patients (average of 45 minutes per day per patient). With respect to ethical and social aspects the discussion focusses on the problem of autonomy: dementia does not necessarily mean inability to decide over the participtation in studies. Legal questions address the financial situation of patients, the organisation of their care and the legal representation of dementia patients. Discussion: Only a few studies on the nursing interventions considered in this report are methodologically robust. Most of the studies have a small number of participants and show substantial differences in terms of their inclusion criteria, implementation, and endpoints. This heterogeneity is reflected in the results: in half of the studies, the interventions have no positive effects compared to the control group. The other half of the studies reports some positive effects with regard to specific endpoints. All of the economic studies are, from a methodologial and a thematic standpoint, not suitable to answer the questions raised. Ethical, social and legal aspects are discussed but not systematically analysed. Conclusion: The studies conducted to date do not provide sufficient evidence of neither efficacy nor cost-effectiveness for any of the nursing interventions considered in the present HTA. However, lack of evidence does not mean lack of efficacy. Instead, more methodologically sound studies are needed. Particullary desireable are studies reflecting the framework of dementia care in Germany. This holds also for the healtheconomic evaluations of the chosen interventions.
The new coronavirus (COVID-19) pandemic and the resulting response measures have led to severe limitations of people's exercise possibilities with diminished physical activity (PA) and increased sedentary behavior (SB). Since for migrant groups in Germany, no data is available, this study aimed to investigate factors associated with changes in PA and SB in a sample of Turkish descent. Participants of a prospective cohort study (adults of Turkish descent, living in Berlin, Germany) completed a questionnaire regarding COVID-19 related topics including PA and SB since February 2020. Changes in PA and SB were described, and sociodemographic, migrant-related, and health-related predictors of PA decrease and SB increase were determined using multivariable regression analyses. Of 106 participants, 69% reported a decline of PA, 36% reported an increase in SB. PA decrease and SB increase seemed to be associated with inactivity before the pandemic as well as with the female sex. SB increase appeared to be additionally associated with educational level and BMI. The COVID-19 pandemic and the response measures had persistent detrimental effects on this migrant population. Since sufficient PA before the pandemic had the strongest association with maintaining PA and SB during the crisis, the German government and public health professionals should prioritize PA promotion in this vulnerable group.

Aims: The clinical effectiveness of primary prevention implantable cardioverter defibrillator (ICD) therapy is under debate. The EUropean Comparative Effectiveness Research to Assess the Use of Primary ProphylacTic Implantable Cardioverter Defibrillators (EU-CERT-ICD) aims to assess its current clinical value. Methods and results: The EU-CERT-ICD is a prospective investigator-initiated non-randomized, controlled, multicentre observational cohort study performed in 44 centres across 15 European Union countries. We will recruit 2250 patients with ischaemic or dilated cardiomyopathy and a guideline indication for primary prophylactic ICD implantation. This sample will include 1500 patients at their first ICD implantation and 750 patients who did not receive a primary prevention ICD despite having an indication for it (non-randomized control group). The primary endpoint is all-cause mortality; the co-primary endpoint in ICD patients is time to first appropriate shock. Secondary endpoints include sudden cardiac death, first inappropriate shock, any ICD shock, arrhythmogenic syncope, revision procedures, quality of life, and cost-effectiveness. At baseline (and prior to ICD implantation if applicable), all patients undergo 12-lead electrocardiogram (ECG) and Holter ECG analysis using multiple advanced methods for risk stratification as well as detailed documentation of clinical characteristics and laboratory values. Genetic biobanking is also organized. As of August 2018, baseline data of 2265 patients are complete. All subjects will be followed for up to 4.5 years. Conclusions: The EU-CERT-ICD study will provide a necessary update about clinical effectiveness of primary prophylactic ICD implantation. This study also aims for improved risk stratification and patient selection using clinical and ECG risk markers.
