Objective: Metabolic Syndrome (MetSyn) describes a cluster of metabolic disorders and is considered a risk factor for development of cardiovascular disease. Although a high prevalence is commonly assumed in Germany data about the degree of its occurrence in the population and in subgroups are still missing. The aim of this study was to assess the prevalence of the MetSyn according to the NCEP ATP-III (National Cholesterol Education Program Adult Treatment Panel III) criteria in persons aged ≥18 years attending a general practitioner in Germany. Here we describe in detail the methods used and the feasibility of determining the MetSyn in a primary health care setting. Research design and methods: The German-wide cross-sectional study was performed during two weeks in October 2005. Blood samples were analyzed in a central laboratory. Waist circumference and blood pressure were assessed, data on smoking, life style, fasting status, socio-demographic characteristics and core information from non-participants collected. Quality control procedures included telephone-monitoring and random on-site visits. In order to achieve a maximal number of fasting blood samples with a minimal need for follow-up appointments a stepwise approach was developed. Basic descriptive statistics were calculated, the Taylor expansion method used to estimate standard errors needed for calculation of confidence intervals for clustered observations. Results: In total, 1511 randomly selected general practices from 397 out of 438 German cities and administrative districts enrolled 35,869 patients (age range: 18-99, women 61.1%). More than 50,000 blood samples were taken. Fasting blood samples were available for 49% of the participants. Of the participating patients 99.3% returned questionnaires to the GP, only 12% were not filled out completely. The overall prevalence of the MetSyn (NCEP/ATP III 2001) was found to be 19.8%, with men showing higher prevalence rates than women (22.7% respective 18.0%). Conclusions: This study was designed to provide data as robust as possible within the confines of an epidemiological study. Judging by the low degree of missing data and the high data quality, the feasibility for this kind of a research setting (short evaluation period, practitioners as data assessment sites) was found to be very good. The results will help to gain a more comprehensive insight into the prevalence of MetSyn for patients in primary health care in Germany.

Medicine - Abstract
Aim: On behalf of the German Agency for Health Technology Assessment (DAHTA@DIMDI) a rapid economic HTA was conducted. Aim of the HTA was to evaluate the cost-effectiveness of quantitative ultrasound (QUS) for screening of osteoporotic fracture risk. Study population was formed by postmenopausal women. QUS was compared to the dual X-ray absorptiometry (DXA) as the most frequently used method of measurement. Methods: According to the recommendations for rapid economic HTA a comprehensive literature search was conducted. Data of identified and relevant publications have been extracted in form of a qualitative and quantitative information synthesis. The authors calculated incremental cost-effectiveness ratios for different screening procedures: (1) one-step proceeding comparing QUS with DXA, (2) two-step proceeding starting with QUS followed by DXA in pathologic cases. Results: An additional case diagnosed by DXA in a one-step proceeding rises additional costs of about 1,000 EURO. A two-step proceeding with QUS is cost-effective as long as the costs of one QUS examination are lower than 31%-51% of the costs of one DXA examination. Discussion: All considered studies showed methodological limitations. None of them included long term effects like avoided bone fractures. Considering long-term effects probably would change the results. Due to the weakness of data no concluding judgement about the cost-effectiveness of QUS can be given.

Der Import Chinesischer Arzneidrogen aus China bereitet immer wieder Probleme bezuglich der Verfugbarkeit, Qualitat und Verunreinigungen mit Schwermetallen und Pestiziden. Deshalb wird seit 1999 ein kontrollierter Anbau von wichtigen Chinesischen Arzneipflanzen in Bayern von der Bayerischen Landesanstalt fur Landwirtschaft in einem interdisziplinaren Forschungsprojekt betrieben und wissenschaftlich erforscht. Zur Zeit werden 16 „bayerische Arzneidrogen“ uber Apotheken abgegeben. Wirkstoffbestimmungen, sensorische und Qualitats-Analysen zeigen eine hohe, vergleichbare Qualitat der bayerischen Arzneimittel. Dennoch wurde von Vorbehalten berichtet. Die bayerischen Arzneimittel werden seit 2006 in der medizinischen Versorgung von Patienten in Deutschland eingesetzt, ohne dass die Wirksamkeit im Vergleich zu den Chinesischen Arzneimitteln bis jetzt untersucht wurde. Aus diesem Grund wurde eine Therapiebeobachtung mit einem Parallelgruppendesign bei Patienten mit chronischer Rhinosinusitis durchgefuhrt. Die Beobachtungsdauer betrug vier Wochen. Erneut nach vier Wochen wurden die Patienten nochmals telefonisch befragt. Wahrend der Therapiebeobachtung nahmen die Patienten taglich 2 x 50 ml eines Dekokts aus Chinesischen Arzneimitteln entweder (a) uberwiegend aus bayerischem kontrolliertem Versuchsanbau (Bayern-Gruppe) oder (b) rein chinesischer Handelsware (China-Gruppe) zu sich. Die Zusammensetzung des Dekokts wurde in einem Konsensusprozess mit Experten im Bereich der Chinesischen Medizin festgelegt. Es erfolgte keinerlei Eingriff in die Therapieentscheidungen der teilnehmenden Arzte, andere Therapieformen wie Akupunktur wurden angewandt. Die Bewertung des Therapieerfolgs erfolgte durch Numerische Rating- Skalen. Insgesamt beendeten 64 Patienten die Therapiebeobachtung (31 Bayern-Gruppe, 33 China-Gruppe). Es zeigten sich in beiden Gruppen deutliche Verbesserungen in den Hauptsymptomen der chronischen Rhinosinusitis wie auch in den Nebensymptomen wie Infektneigung und allgemeiner Gesundheitszustand. Zwischen den Gruppen gab es keine relevanten Unterschiede bei der Besserung der Hauptsymptome. Die Dekokte waren insgesamt gut vertraglich, schwere Nebenwirkungen traten nicht auf. Chinesische Arzneimittel aus bayerischem Anbau waren in dieser Beobachtungsstudie gleich wirksam wie Arzneikrauter aus China. Die Veranderung der Symptome wahrend der Behandlungszeit ist deutlich und sollte zu weiteren Studien Anlass geben, die die Wirksamkeit dieser Arzneimittelrezeptur bei chronischer Rhinosinusitis untersuchen.

[english] Menopause is described as the transition from the reproductive phase of a women to the non reproductive. Changes in hormone levels might lead to complaints and health consequences especially during peri- and postmenopause. Hormone therapy has a potential damaging health risk profile and is recommended for temporal limited therapy for acute vasomotor symptoms only.The present HTA-report aims to assess the effectiveness and the cost-effectiveness of alternative treatment methods for women with postmenopausal symptoms in Germany regarding patient relevant endpoints (reduction of symptoms and frequency of adverse events and improvement of quality of life).A systematic literature search was carried out in 33 relevant databases in September 2010. Citations were selected according to pre-defined criteria and were extracted and evaluated.In the systematic research 22 studies are identified for the effectiveness evaluation, 22 primary studies and one review.High doses of isolated genistein reduce the frequency/intensity of hot flashes while low doses of genistein show no significant effect. Intake of isoflavone extract such as genistein, daidzein, glycitein in various combinations does not have an effect on improvement of cognitive function or vaginal dryness. The effect of black cohosh and hop extract for menopausal complaints cannot be determined since results are heterogenous. The combination of isoflavone, black cohosh, monk’s pepper, valerian and vitamin E has a positive effect on menopause symptoms. Ginkgo biloba shows no significant effect on menopause symptoms and cognitive improvement beside mental flexibility. Acupuncture has a significant influence on hot flashes especially in severe cases.No final statement can be drawn regarding the effectiveness of alterne treatment methods due to qualitative shortcomings of included studies and a general limited availability of studies in this field. Furthermore, the generalization of the present HTA is limited due to the inclusion of only postmenopausal women.[german] Als Wechseljahre wird der Übergang von der reproduktiven Phase der Frau zur nicht-reproduktiven beschrieben. Insbesondere in der Peri- und Postmenopause können Beschwerden aufgrund des sich veränderten Hormonspiegels auftreten. Aktuell wird die Hormontherapie wegen der mit dieser verbundenen Risiken nur noch zur kurzfristigen Behandlung akuter vasomotorischer Symptome empfohlen. Von den betroffenen Frauen werden alternative und komplementäre Heilmethoden eingesetzt.Im vorliegenden Health Technology Assessment (HTA) sollen die Effektivität und Kosteneffektivität alternativer Behandlungsmethoden von postmenopausalen Wechseljahresbeschwerden in Deutschland hinsichtlich der patientenrelevanten Endpunkte Verringerung der Symptomatik, Häufigkeit unerwünschter Ereignisse sowie Verbesserung der Lebensqualität bewertet werden. In 33 relevanten Datenbanken wird im September 2010 eine systematische Literatursuche durchgeführt. Gefundene und relevante Literaturstellen werden gemäß vorab definierter Kriterien selektiert. Die Daten der Literaturstellen werden gezielt herausgesucht, bewertet und zusammenfassend beurteilt.Aus der systematischen Recherche werden 22 Studien, davon 15 Primärstudien und ein Review zur Bewertung der Effektivität identifiziert.Hochdosiertes isoliertes Genistein reduziert die Anzahl/Schwere von Hitzewallungen, während niedrig dosiertes Genistein keinen signifikanten Effekt zeigt. Die Gabe von Isoflavonextrakten, die Genistein, Daidzein, Glycitein in unterschiedlicher Zusammensetzung enthalten, hat keinen signifikanten Einfluss auf die Verbesserung kognitiver Fähigkeiten oder vaginale Trockenheit. Traubensilberkerzen- und Hopfenextrakt führen zu unterschiedlichen Ergebnissen bezüglich der Wirksamkeit bei postmenopausalen Beschwerden, sodass keine abschließende Aussage zur Effektivität getroffen werden kann. Die Kombination von Isoflavonen, Traubensilberkerze, Mönchspfeffer, Baldrian und Vitamin E hat eine positive Wirkung auf postmenopausale Symptome. Ginkgo biloba zeigt keinen signifikanten Effekt auf postmenopausale Symptome und eine kognitive Verbesserung mit Ausnahme der mentalen Flexibilität. Akupunktur hat einen signifikanten Einfluss auf Hitzewallungen, insbesondere auf deren Schweregrad.Aufgrund der qualitativen Mängel (Concealment, Randomisierung, Fallzahlplanung) der eingeschlossenen Studien und der begrenzten Anzahl an Studien kann keine abschließende zusammenfassende Bewertung zur Wirksamkeit alternativer Heilmethoden gegeben werden. Die Verallgemeinerbarkeit des vorliegenden HTA wird durch die Beschränkung auf postmenopausale Frauen reduziert.

Background Persistent infections with high-risk types of human papillomavirus (HPV) are associated with the development of cervical neoplasia. Compared to cytology HPV testing is more sensitive in detecting high-grade cervical cancer precursors, but with lower specificity. HPV based primary screening for cervical cancer is currently discussed in Germany. Decisions should be based on a systematic evaluation of the long-term effectiveness and cost-effectiveness of HPV based primary screening. Research questions What is the long-term clinical effectiveness (reduction in lifetime risk of cervical cancer and death due to cervical cancer, life years gained) of HPV testing and what is the cost-effectiveness in Euro per life year gained (LYG) of including HPV testing in primary cervical cancer screening in the German health care context? How can the screening program be improved with respect to test combination, age at start and end of screening and screening interval and which recommendations should be made for the German health care context? Methods A previously published and validated decision-analytic model for the German health care context was extended and adapted to the natural history of HPV infection and cervical cancer in order to evaluate different screening strategies that differ by screening interval, and tests, including cytology alone, HPV testing alone or in combination with cytology, and HPV testing with cytology triage for HPV-positive women. German clinical, epidemiological and economic data were used. In the absence of individual data, screening adherence was modelled independently from screening history. Test accuracy data were retrieved from international meta-analyses. Predicted outcomes included reduction in lifetime-risk for cervical cancer cases and deaths, life expectancy, lifetime costs, and discounted incremental cost-effectiveness ratios (ICER). The perspective of the third party payer and 3% annual discount rate were adopted. Extensive sensitivity analyses were performed in order to evaluate the robustness of results and identify areas of future research. Results In the base case analysis screening resulted in a 53% to 97% risk reduction for cervical cancer with a discounted ICER between 2,600 Euro/LYG (cytology alone every five years) and 155,500 Euro/LYG (Annual cytology age 20 to 29 years, and annual HPV age 30 years and older). Annual cytology, the current recommended screening strategy in Germany, was dominated. In sensitivity analyses variation in the relative increase in the sensitivity of HPV testing as compared to cytology, HPV test costs, screening adherence, HPV incidence, and annual discount rate influenced the ICER results. Variation in the screening start age also influenced the ICER. All cytology strategies were dominated by HPV screening strategies, when relative sensitivity increase by HPV testing compared to cytology was higher (scenario analysis with data for test accuracy from German studies). HPV testing every one, two or three years was more effective than annual cytology. With increased screening adherence a longer screening interval and with low screening adherence a shorter interval would be more cost-effective. With a reduction in HPV incidence of more than 70% triennial HPV screening in women aged 30 years and older (and biennial Pap screening in women aged 20 to 29 years) is cost-effective. The discounted ICER increases with increasing annual discount rate. Increasing screening start age to 25 years had no relevant loss in effectiveness but resulted in lower costs. An optimal strategy may be biennial HPV testing age 30 years and older with biennial cytology at age 25 to 29 years (ICER of 23,400 Euro/LYG). Conclusions Based on these results, HPV-based cervical cancer screening is more effective than cytology and could be cost-effective if performed at intervals of two years or greater. Increasing the age at screening start to 25 years causes no relevant loss in effectiveness but saves resources. In the German context an optimal screening strategy could be biennial HPV testing at age 30 years and older with biennial cytology at the age of 25 to 29 years. An extension to a three-yearly screening interval requires substantially improved screening adherence or a higher relative increase in the sensitivity of HPV testing as compared to cytology. The implementation of an organised screening program for quality-controlled introduction of HPV-screening and -vaccination with continued systematic outcome evaluation is recommended., GMS Health Technology Assessment; 6:Doc05; ISSN 1861-8863

Background Attention-Deficit/Hyperactivity Disorder (ADHD) is a mental disorder. Symptoms include hyperactivity, lack of attentiveness, and frivolousness. This disorder always begins in childhood, but can remain through adulthood. ADHD affects all areas of life and limits the quality of life due to its symptoms and the high rate of associated disorders that can develop. An established form of therapy is using stimulant medications, most commonly, containing Methylphenidate as the active ingredient. However, in Germany this ingredient is not approved for adults suffering from ADHD. Therefore, many adults cannot obtain appropriate medication to treat this disorder. Objective The following report (Health Technology Assessment [HTA]) examines the effectiveness and cost-effectiveness of the medical treatment of ADHD in adults as well as the ethical, social and legal aspects thereof. Methods In August 2009, a systematic literature search is performed in all relevant scientific databases. The selected citations fulfill predetermined inclusion criteria. The data in the publications is then systematically extracted, reviewed and assessed. A manual search of citations is conducted as well. Results Nineteen studies fulfill the inclusion criteria: nine randomised controlled studies (RCT), five meta-analyses, three economic studies and two studies relevant to the legal aspects of the HTA. All RCT reveal that adult patients who receive medication containing a stimulant (Methylphenidate and Amphetamine) and Atomoxetine, see a reduction of ADHD symptoms compared to the placebo-treated patients. The drug response rate among the control group ranges from 7 to 42%; in the treatment group from 17 to 59.6%. The meta-analyses confirm the findings of the RCT. In light of the control group, it can be ascertained that there are higher annual costs (both direct and indirect) for patients with ADHD. The average annual medical expenses for an adult with ADHD were 1,262 $ in 1998 and 1,673 $ in 2001 (the converted and inflation-adjusted rate for 2009: between 1,270 and 1,619 Euro). The use of stimulants use may impair the patient’s ability to drive, travel or do sports. No relevant studies can be identified concerning the ethical, social and/or legal aspects of stimulant medication for ADHD patients. Discussion/Conclusion Medical treatment, particularly including Methylphenidate and Atomoxetine, proves to have a positive effect. In order to attain an optimal drug response, dosing must be determined on an individual basis. There is a need of high-quality studies that directly compare various agents – an aspect which is relevant to medical effectiveness of a therapy. No definite statement can be made about the cost-effectiveness of the medical treatment of ADHD in adults. More health economic studies are therefore required. Apart from the unquestionable mental indication, it is already recommended by health economic reasons to establish the conditions for an adequate treatment with these medicaments also for adults., Schriftenreihe Health Technology Assessment (HTA) in der Bundesrepublik Deutschland; 108e; ISSN 1864-9645

Hintergrund Bei der Aufmerksamkeitsdefizit-/Hyperaktivitätsstörung (ADHS) handelt es sich um eine psychische Störung. Die betroffenen Personen sind in der Regel überaktiv, unachtsam und leichtfertig. Diese Erkrankung beginnt immer im Kindesalter, kann aber bis ins Erwachsenenalter bestehen bleiben. Sie wirkt sich für die Betroffenen in nahezu allen Lebensbereichen aus. Die Lebensqualität ist häufig infolge der typischen Symptome und der hohen Rate an Begleiterkrankungen eingeschränkt. Eine bewährte Form der Therapie ist die Behandlung mit anregend wirkenden Arzneimitteln. In erster Linie wird der Wirkstoff Methylphenidat eingesetzt. Er ist für die Behandlung der ADHS im Erwachsenenalter in Deutschland nicht zugelassen. Das führt dazu, dass viele betroffene Erwachsene keine entsprechende Medikation erhalten. Forschungsfrage In dem vorliegenden Bericht (Health Technology Assessment [HTA]) werden die gewünschte Wirkung (Effektivität), die Wirkung in Zusammenhang mit den Kosten (Kosten-Effektivität) sowie ethische, soziale und rechtliche Gesichtspunkte bei der medikamentösen Behandlung von Erwachsenen mit einer ADHS betrachtet. Methodik In wissenschaftlichen Datenbanken wird im August 2009 eine systematische Literatursuche durchgeführt. Gefundene Literaturstellen müssen vorab definierten Kriterien entsprechen. Die Daten der Literaturstellen werden gezielt herausgesucht, bewertet und zusammenfassend beurteilt. Ergänzend wird eine Handsuche durchgeführt. Ergebnisse Insgesamt erfüllen 19 Studien, davon neun kontrollierte Studien, mit zufälliger Verteilung der Versuchspersonen bezüglich der Behandlung, fünf Metaanalysen (Untersuchung von zusammengefassten Einzelstudien), drei Studien zu wirtschaftlichen und zwei zu rechtlichen Gesichtspunkten die vorgegebenen Einschlusskriterien. Alle bewerteten randomisierten, kontrollierten Studien (RCT) zeigen, dass unter medikamentöser Behandlung vor allem mit Arzneimitteln mit anregender Wirkung (Methylphenidat und Amphetaminen) und Atomoxetin eine Verbesserung der ADHS-Symptome bei Erwachsenen im Vergleich zu einer Placebobehandlung auftritt. Die Ansprechraten belaufen sich in den Kontrollgruppen zwischen 7% und 42%, in den Behandlungsgruppen zwischen 17% und 59,6%. In den Metaanalysen werden die Ergebnisse aus den RCT bestätigt. Insgesamt lassen sich für Patienten mit ADHS hohe jährliche direkte (z.B. für Medikamente) und indirekte (z.B. für Verdienstausfall) Kosten im Vergleich zu einer Kontrollgruppe feststellen. Die durchschnittlichen Medikamentenkosten für Erwachsene mit ADHS betragen zwischen 1.262 US-Dollar im Jahr 1998 und 1.673 US-Dollar im Jahr 2001 (Währung und Inflation berücksichtigt: für 2009 zwischen 1.270 und 1.619 Euro). Im Zusammenhang mit der Einnahme von Arzneimitteln mit stimulierender Wirkung können Betroffene in den Bereichen Straßenverkehr, Reisen und Sport eingeschränkt sein. Für ethische und soziale sowie für rechtliche Aspekte in Bezug zur medikamentösen Therapie bei Erwachsenen mit einer ADHS werden keine entsprechenden Studien gefunden. Diskussion/Schlussfolgerung Insbesondere bei Methylphenidat und Atomoxetin sind positive Effekte der medikamentösen Therapie nachweisbar. Dabei muss eine Dosiseinstellung abgestimmt auf die jeweilige betroffene Person erfolgen, um ein optimales Ansprechen der Medikamente zu erreichen. Um genauere Aussagen über die Kosten-Wirkung der medikamentösen Therapie bei Erwachsenen mit einer ADHS zu treffen, sind weitere gesundheitsökonomische Studien erforderlich. Abgesehen vom zweifelsfrei psychiatrischen Krankheitsbild wird allein schon aus gesundheitsökonomischen Gründen empfohlen, die Voraussetzungen für eine angemessene Versorgung mit diesen Medikamenten auch für Erwachsene zu schaffen., Schriftenreihe Health Technology Assessment (HTA) in der Bundesrepublik Deutschland; 108; ISSN 1864-9645

Hintergrund Eine persistente Infektion mit einem Hochrisikotyp des Humanen Papillomavirus (HPV) ist mit der Entwicklung von Zervixkrebs und seinen Vorstufen assoziiert. Die HPV-DNA-Diagnostik (DNA = Desoxyribonukleinsäure) erzielte in Studien eine höhere Sensitivität als die aktuell eingesetzte Zytologie, jedoch eine geringere Spezifität. Ihr Einsatz als Primärscreeningverfahren in der Zervixkarzinomfrüherkennung wird aktuell diskutiert. Eine systematische Evaluation der Langzeit-Effektivität und Kosten-Effektivität der HPV-DNA-Diagnostik allein oder in Kombination mit der Zytologie als Primärscreeningverfahren in der Zervixkarzinomfrüherkennung für den Kontext des deutschen Gesundheitssystems sollte erfolgen. Forschungsfragen Wie sind die medizinische Langzeit-Effektivität (Reduktion des Lebenszeitrisikos für Zervixkarzinom und Mortalität durch Zervixkarzinom, gewonnene Lebenserwartung) und Kosten-Effektivität (Euro pro gewonnenes Lebensjahr [LJ]) der HPV-DNA-Diagnostik als Primärscreeningverfahren in der Zervixkarzinomfrüherkennung im Kontext des deutschen Gesundheitssystems zu bewerten? Wie kann die Screeningstrategie bezüglich der Testkombination, oberen und unteren Altersgrenzen und dem Screeningintervall optimiert werden. Welche Empfehlungen sind hieraus für den deutschen Kontext abzuleiten? Methodik Ein für den Kontext des deutschen Gesundheitssystems publiziertes und validiertes entscheidungsanalytisches Modell wird für den natürlichen Krankeitsverlauf der HPV-Infektion und der Zervixkarzinomentwicklung erweitert und adaptiert, um verschiedene Screeningstrategien, die sich hinsichtlich der Screeningintervalle und der Algorithmen der Testverfahren unterscheiden, zu evaluieren. Es werden Zytologie allein, HPV-Screening allein oder in Kombination mit der Zytologie sowie HPV-Screening mit zytologischer Triage von HPV-positiven Frauen evaluiert. Deutsche klinische, epidemiologische und ökonomische Daten gehen in das Modell ein. Mangels individueller Daten zur Teilnahmerate in Deutschland wird diese unabhängig von der Geschichte der Screeninginanspruchnahme modelliert. Daten zur Testgüte werden internationalen Metaanalysen entnommen. Zielparameter der Analysen sind die Reduktion des Lebenszeitrisikos für Zervixkrebs und Tod durch Zervixkrebs, Restlebenserwartung, Lebenszeitkosten und das diskontierte inkrementelle Kosten-Effektivitäts-Verhältnis (IKEV). Es wird die Perspektive des Kostenträgers eingenommen und eine jährliche Diskontierung von 3% gewählt. Zur Untersuchung der Robustheit der Analyseergebnisse und zur Identifikation von weiterem Forschungsbedarf werden umfangreiche Sensitivitätsanalysen durchgeführt. Ergebnisse In der Basisfallanalyse erzielt Screening im Vergleich zu keinem Screening eine Reduktion des Zervixkrebsrisikos von 53% bis 97%. Die diskontierten IKEV liegen zwischen 2.600 Euro/LJ (Zytologie allein alle fünf Jahre) und 155.500 Euro/LJ (für jährliche Zytologie im Alter von 20 bis 29 Jahren und jährliches HPV-Screening ab dem Alter von 30 Jahren). Die jährliche Zytologie, wie derzeit in Deutschland empfohlen, wird von anderen Screeningstrategien dominiert. In Sensitivitätsanalysen zeigt sich ein Einfluss von relativer Sensitivitätserhöhung des HPV-Tests versus Zytologie, HPV-Testkosten, Teilnahmerate, HPV-Inzidenz und der jährlichen Diskontrate auf die Analyseergebnisse. Auch das Alter bei Screeningbeginn beeinflusste die Ergebnisse. In der Szenarioanalyse mit Testgütekriteriendaten aus deutschen Studien (niedrigere relative Sensitivität von Pap- versus HPV-Test) werden alle Zytologiestrategien von HPV-Screeningstrategien dominiert. HPV-Screening im 1-, 2- oder 3-Jahres-Intervall ist effektiver als jährliche Zytologie. Bei höherer Teilnahmerate könnte ein längeres, bei niedriger Teilnahmerate ein kürzeres Screeningintervall sinnvoller und kosteneffektiver sein. Bei einer Reduktion der HPV-Inzidenz um mehr als 70% ist ein dreijährliches HPV-Screening ab einem Alter von 30 Jahren und zweijährliche Zytologie im Alter von 20 bis 29 Jahren kosteneffektiv. Mit steigender Diskontrate nimmt das IKEV der verschiedenen Strategien zu. Die Erhöhung des Alters für den Screeningbeginn auf 25 Jahre hat keinen relevanten Effektivitätsverlust zur Folge und reduziert den Ressourcenverbrauch. Mit einem IKEV von 23.400 Euro/LJ könnte das HPV-Screening ab einem Alter von 30 Jahren und Zytologie im Alter von 25 bis 29 Jahren jeweils im 2-Jahres-Intervall unter Berücksichtigung von Effektivität und Kosten-Effektivität die optimale Strategie sein. Schlussfolgerungen Auf der Grundlage der Analyseergebnisse dieses HTA-Berichts ist das HPV-basierte Zervixkrebsscreening effektiver als die Zytologie und als kosteneffektiv zu bewerten, wenn es je nach gesellschaftlicher Zahlungsbereitschaft mit Screeningintervallen von zwei oder mehr Jahren durchgeführt wird. Die Erhöhung des Alters für den Screeningbeginn auf 25 Jahre hat keinen relevanten Effektivitätsverlust zur Folge, spart aber Ressourcen. Für den deutschen Screeningkontext könnte HPV-Screening ab einem Alter von 30 Jahren und Zytologie im Alter von 25 bis 29 Jahren jeweils im 2-Jahres-Screeningintervall eine optimale Strategie sein. Eine Verlängerung des Screeningintervalls auf drei Jahre wäre nur bei einer hohen Screeningteilnahmerate oder einer größeren relativen Sensitivitätserhöhung durch den HPV-Test versus Zytologie sinnvoll. Die Einführung eines organisierten Screeningprogramms für eine qualitätskontrollierte Einführung von HPV-Screening mit kontinuierlicher systematischer Prozessüberwachung und Ergebnisevaluation wird empfohlen., Schriftenreihe Health Technology Assessment (HTA) in der Bundesrepublik Deutschland; 98; ISSN 1864-9645

Gesundheitswissenschaften ,Health sciences - Abstract
Mit dem Wettbewerbsstärkungsgesetz von April 2007 kann das Institut für Qualität und Wirtschaftlichkeit im Gesundheitswesen (IQWiG) vom Gemeinsamen Bundesausschuss (G-BA) mit der Kosten-Nutzen-Bewertung von Arzneimitteln beauftragt werden. Im Januar 2008 hat das IQWiG in einem ersten Methodenvorschlag dargelegt, wie es die Kosten-Nutzen-Bewertung zukünftig durchzuführen gedenkt. In der vorliegenden Stellungnahme der AG Methoden der gesundheitsökonomischen Evaluation (AG MEG) wird der Methodenvorschlag des IQWiG kritisch bewertet und Empfehlungen für eine Weiterentwicklung der Methoden gegeben. Zentrale Aussagen der Stellungnahme sind: (1) Das Methodenpapier ist unbalanciert. Es widmet sich zu einem überwiegenden Teil nicht dem Assessment, der eigentlichen Aufgabe des IQWiG, sondern dem Appraisal, das von den nachfolgenden Entscheidungsträgern (Gemeinsamer Bundesausschuss und Spitzenverband Bund) zu leisten ist. (2) Das IQWiG beabsichtigt, lediglich indikationsspezifische Vergleiche durchführen. Es übersieht dabei, dass die Entscheidungsträger über Erstattungsbeträge von Arzneimitteln in unterschiedlichen Indikationsgebieten entscheiden und dabei faktisch jeweils auch über die Gesundheitsausgaben insgesamt entscheiden. (3) Das IQWiG beabsichtigt ein zweistufiges Bewertungsverfahren, bei dem eine Kosten-Nutzen-Bewertung nur durchgeführt wird, wenn die vorgeschaltete Nutzenbewertung einen Zusatznutzen ausweist. Insofern ist sicherzustellen, dass alle relevanten Nutzenkomponenten der Kosten-Nutzen-Bewertung bereits in der Nutzenbewertung berücksichtigt werden. Dementsprechend sind spezifische gesundheitsökonomische Nutzenparameter (wie zum Beispiel QALYs) zu berücksichtigen, zudem sollte die Community Effectiveness abgebildet werden und die langfristigen Outcomes sollten bereits in der Nutzenbewertung modelliert werden. In der Stellungnahme werden weitere Probleme diskutiert, die sich um die zentralen Kritikpunkte gruppieren. Zudem erweist sich, dass der Methodenvorschlag des IQWiG noch nicht vollständig ist. Dementsprechend wird empfohlen, auch für die nächste Fassung des Methodenvorschlags ein Stellungnahmeverfahren vorzusehen. Since the coming into force of the GKV-Wettbewerbsstärkungsgesetz ("Act to strengthen competition in the statutory health insurance system") in April 2007, the Gemeinsame Bundesausschuss (G-BA "Federal Joint Committee") can commission the Institut für Qualität und Wirtschaftlichkeit im Gesundheitswesen (IQWiG--Institute for Quality and Efficiency in Health Care") with the assessment of costs and benefits of drugs. In January 2008, IQWiG published a working document for consultation describing the proposed methods for carrying out those evaluations. This commentary by the AG Methoden der Gesundheitsökonomischen Evaluation (AG MEG--"Working Group for methods of economic evaluation in health care") provides a critical appraisal and recommendations for the further development of IQWIG's draft guidelines. The core statements of the commentary are as follows: (1) The draft guidelines are unbalanced. Instead of providing comprehensive methodological guidance for health technology assessment, which is the actual task of IQWiG, they deal predominantly with the methods of technology appraisal which is in the responsibility of the decision-making bodies, i.e. of the G-BA and the Spitzenverband Bund der Krankenkassen ("Central Federal Association of Health Insurance Funds"). (2) IQWiG intends to compare the cost-effectiveness of alternative treatment options only within a given therapeutic area. The rationale for this restriction is not clear, as the decision-makers have to determine ceiling prices across therapeutic areas and diseases and effectively the overall volume of health care expenditure, as well. (3) IQWiG aims at carrying out an economic evaluation only if in a preceding benefit assessment a drug has been judged to be superior. Therefore, it has to be assured that the benefit assessment is performed in such a way that its results may be used for the economic assessment. This requires the application of summary scores for the joint measurement of multidimensional endpoints (as, e.g., QALYs), to evaluate community effectiveness instead of efficacy, and to choose a time horizon that is sufficiently long to reflect any differences in the health benefits between the technologies being compared. Furthermore, the comment hints at some additional problems embodied in the draft guidelines and a number of key methodological issues which are not discussed at all in the working document. In summary, the methods currently proposed by IQWiG are not up to the task of conducting economic evaluations. It is strongly recommended to perform a public consultation process for the revised draft guidelines anew.

Introduction: Obesity is a worldwide health problem whose prevalence is on the increase. Many obesity-associated diseases require intensive medical treatment and are the cause of a large proportion of health-related expenditures in Germany. Treatment of obesity includes nutritional, exercise and behaviour therapy, usually in combination. The goal of behaviour therapy for obesity is to bring about a long-term alteration in the eating and exercise habits of overweight and obese individuals. Under certain circumstances, drug treatment may be indicated. Objectives: What is the effectiveness of behaviour therapy for obesity considering approved drugs reduce weight under medical, economic, ethical-social and legal aspects? Methods: A systematic review was conducted using relevant electronic literature databases. Publications chosen according to predefined criteria are evaluated by approved methodical standards of the evidence-based medicine systematically and qualitatively. Results: In total 18 studies, included one HTA and one meta-analysis could be identified according to the predefined inclusion criteria. Three studies compare behaviour therapy to other therapy forms (advice or instruction on nutritional changes, physical activity or a combination of the two), six studies evaluate different forms of behaviour therapy, four studies and four studies compare behaviour therapies mediated by Internet or telephone. Three studies could be identified examining the effect of the combination of behaviour and drug therapy. Furthermore one HTA and one meta-analysis could be included in the evaluation. The behaviour therapy in comparison with other therapy forms reveals a higher effectiveness. In comparison of the different therapeutic approaches of the behaviour therapy intensive behaviour therapy forms and group therapy show a higher effectiveness. Studies related to behaviour therapy based on media support demonstrate a weight reduction both through the interventions of media alone as well as through the intervention of media in conjunction with personal support within the groups. However, analyses of the inter-group comparisons offer no statistically significant difference. However, analyses of the inter-group comparisons offer no statistically significant difference. Comparative analyses confirm the effectiveness of behaviour therapy in combination with additional drug treatment when compared to behaviour therapy alone.In all the studies presented here, relevant changes in weight of -5% to -10% are only partially achieved. High weight losses of less than -10% were found among the intervention group in two of the studies. One study reported a weight loss of -11.4% with the “group therapy” intervention method, while another study reported a weight loss of -11.2% with the “behaviour therapy plus drug treatment” intervention method. Studies with a subsequent follow-up period indicate a clear weight loss at the end of the intervention followed by a renewed weight gain towards the end of the follow-up period.For the evaluation of economic, social-ethical or legal aspects we could not identify any studies. Discussion: A comparative assessment among the studies proved difficult due to their heterogeneous nature. Little conformity can be detected in either the contents of the behaviour therapy or in the treatment plans. The length of the follow-up periods also varies from study to study. Many studies only analyze weight changes within one group or for the entire study population. However, the results of these analyses all indicate a significant weight loss at the end of the intervention. Conclusion: Some effects of behaviour therapy on a reduction in weight can be shown. However, relevant weight changes of -5% to -10% are only achieved to a certain extent. The extremely heterogeneous nature of the interventions makes a comparison of the study results very difficult. A trend can be detected indicates that those treatments which offer drug treatment in addition to behaviour therapy are more effective than behaviour therapy alone. For the verification of long-term successes of a behaviour therapy too few data are available.

Objective: Metabolic Syndrome (MetSyn) describes a cluster of metabolic disorders and is considered a risk factor for development of cardiovascular disease. Although a high prevalence is commonly assumed in Germany data about the degree of its occurrence in the population and in subgroups are still missing. The aim of this study was to assess the prevalence of the MetSyn according to the NCEP ATP-III (National Cholesterol Education Program Adult Treatment Panel III) criteria in persons aged ≥18 years attending a general practitioner in Germany. Here we describe in detail the methods used and the feasibility of determining the MetSyn in a primary health care setting. Research design and methods: The German-wide cross-sectional study was performed during two weeks in October 2005. Blood samples were analyzed in a central laboratory. Waist circumference and blood pressure were assessed, data on smoking, life style, fasting status, socio-demographic characteristics and core information from non-participants collected. Quality control procedures included telephone-monitoring and random on-site visits. In order to achieve a maximal number of fasting blood samples with a minimal need for follow-up appointments a stepwise approach was developed. Basic descriptive statistics were calculated, the Taylor expansion method used to estimate standard errors needed for calculation of confidence intervals for clustered observations. Results: In total, 1511 randomly selected general practices from 397 out of 438 German cities and administrative districts enrolled 35,869 patients (age range: 18-99, women 61.1%). More than 50,000 blood samples were taken. Fasting blood samples were available for 49% of the participants. Of the participating patients 99.3% returned questionnaires to the GP, only 12% were not filled out completely. The overall prevalence of the MetSyn (NCEP/ATP III 2001) was found to be 19.8%, with men showing higher prevalence rates than women (22.7% respective 18.0%). Conclusions: This study was designed to provide data as robust as possible within the confines of an epidemiological study. Judging by the low degree of missing data and the high data quality, the feasibility for this kind of a research setting (short evaluation period, practitioners as data assessment sites) was found to be very good. The results will help to gain a more comprehensive insight into the prevalence of MetSyn for patients in primary health care in Germany.

Background: Forearm fractures are the most common fractures in children (23% of all fractures). Basically there are two treatment options available for diaphyseal forearm fractures in children: closed reduction with cast immobilisation (conservative therapy) and the elastic stable intramedullary nailing (ESIN). Treatment decision is influenced by the doctor's estimation of fracture instability. Stable fractures can be treated conservatively whereas instable forearm shaft fractures can be treated according the following three treatment strategies: 1. conservative therapy in an outpatient setting 2. conservative therapy in the operating room in attendance to change to ESIN in case that no stabilisation can be achieved with cast immobilisation 3. immediate treatment with ESIN in the operating room. Objectives: Aim of this Health Technology Assessment (HTA) report is to assess and report the published evidence concerning effectiveness and cost-effectiveness of ESIN as a treatment option for diaphyseal forearm fractures in children and to identify future research need. Important parameters for the assessment of effectiveness are objective parameters (axis deviation, losses of motion, and numbers of reductions in case of redislocations) and subjective parameters (pain or impairment in quality of life). Furthermore, a health economic evaluation shall be done which refers to the costs of the different therapy strategies. Methods: An extensive, systematic literature search in medical, economic, and HTA literature databases was performed. Relevant data were extracted and synthesised. Results: Three cohort studies and seven case series have been identified. Controlled clinical studies, systematic reviews and/or HTA reports that gave evidence to answer the own study question have not been found. The identified studies partly differed in respect of defined indication for ESIN, study population and treatment strategies. For that reason comparability of results was limited. In the majority of cases the publications reported a successful consolidation of fractures treated with ESIN. The cohort studies reported no differences in mobility after treatment with ESIN compared to patients who were treated conservatively. No publications that argue health economic aspects of the ESIN in children could be identified in the literature search. A cost data assessment conducted by the authors of this report showed that ESIN is associated with higher costs compared to the other treatment strategies (without considering long term costs due to reduction in case of redisplacement).ConclusionsLittle evidence for a dominance of ESIN in treating forearm shaft fractures of children compared to conservative therapy could be found. Accomplishment of ESIN without complications causes more costs than conservative therapy both in outpatient and in inpatient setting. However, if fracture stabilisation cannot be achieved by conservative therapy, further interventions will be necessary. They will result in a burden for the patients and higher costs.

MEDICAL screening ,PRIMARY care ,HEPATITIS B ,HEPATITIS C ,MEDICAL care costs - Abstract
Objectives:Systematic screening for chronic hepatitis B and C does not yet exist in Germany. Therefore, the implementation of a screening approach within a preventive medical examination performed by primary care physicians (‘Check-Up 35+’) was evaluated in a recent prospective multicenter study. The present analysis estimates the financial consequences for the statutory health insurance by budget impact analysis. Materials and methods:A Markov cohort model was developed consisting of 21 health states. Four different screening scenarios derived from the previous multicenter study were compared to usual care, a strategy without screening for hepatitis. Actual cost data for Germany were calculated and systematic literature searches for all input parameters were performed. Results:The base case results in incremental costs for the screening strategies compared to no hepatitis screening of 165–227 € per patient in a 20-year horizon. Two main parameters influence the financial consequences: (A) detection and treatment increase the costs in the beginning. (B) Screening avoids hepatitis induced end-stage liver disease. The initial higher costs exceed the later savings. Sensitivity analyses demonstrate a strong impact of medication costs for the treatment of additionally detected hepatitis infections on the outcome. This finding is robust to sensitivity analysis. Conclusions:The screening strategy proposed here implies additional costs for the statutory health insurance, however, a decision regarding its usefulness must consider criteria other than cost. For example, the high burden of disease due to liver cirrhosis and liver carcinoma should be considered. Therefore, an additional cost-effectiveness-analysis should be conducted.

Aim: On behalf of the German Agency for Health Technology Assessment (DAHTA@DIMDI) a rapid economic HTA was conducted. Aim of the HTA was to evaluate the cost-effectiveness of quantitative ultrasound (QUS) for screening of osteoporotic fracture risk. Study population was formed by postmenopausal women. QUS was compared to the dual X-ray absorptiometry (DXA) as the most frequently used method of measurement. Methods: According to the recommendations for rapid economic HTA a comprehensive literature search was conducted. Data of identified and relevant publications have been extracted in form of a qualitative and quantitative information synthesis. The authors calculated incremental cost-effectiveness ratios for different screening procedures: (1) one-step proceeding comparing QUS with DXA, (2) two-step proceeding starting with QUS followed by DXA in pathologic cases. Results: An additional case diagnosed by DXA in a one-step proceeding rises additional costs of about 1,000 EURO. A two-step proceeding with QUS is cost-effective as long as the costs of one QUS examination are lower than 31%-51% of the costs of one DXA examination. Discussion: All considered studies showed methodological limitations. None of them included long term effects like avoided bone fractures. Considering long-term effects probably would change the results. Due to the weakness of data no concluding judgement about the cost-effectiveness of QUS can be given.

The objective of this study was to translate and apply a decision-analytic model for chronic hepatitis C (CHC) to the German health care context using competence network collaboration. The German Hepatitis C Model (GEHMO) competence network used a systematic multistep approach to identify and transfer a high quality Markov model for CHC to the German health care context. GEHMO was used to project lifetime clinical and economic outcomes and to determine the cost-effectiveness of initial antiviral therapy with interferon a-2b plus ribavirin from a societal perspective. In 40-year-old patients combination therapy for 24 and 48 weeks increased life expectancy by 1.6 and 2.3 years, respectively, compared with interferon alone for 48 weeks. The discounted incremental cost-utility ratios (ICUR) for combination therapy were euro 5,500 per quality-adjusted life-year gained (QALY) for 24 weeks and euro 6,800/QALY for 48 weeks of treatment. ICUR was euro 9,800/QALY for moving from 24 to 48 weeks of treatment. Combination therapy remained cost-effective in sensitivity analyses. In conclusion, combination therapy with interferon alpha-2b and ribavirin is effective and cost-effective compared with other well-accepted medical treatments. Competence network collaboration and decision modeling provide a useful and efficient approach to combine evidence from international studies with country-specific parameters. [ABSTRACT FROM AUTHOR]

- Abstract
BACKGROUND: Persistent infections with high-risk types of human papillomavirus (HPV) are associated with the development of cervical neoplasia. Compared to cytology HPV testing is more sensitive in detecting high-grade cervical cancer precursors, but with lower specificity. HPV based primary screening for cervical cancer is currently discussed in Germany. Decisions should be based on a systematic evaluation of the long-term effectiveness and cost-effectiveness of HPV based primary screening. RESEARCH QUESTIONS: What is the long-term clinical effectiveness (reduction in lifetime risk of cervical cancer and death due to cervical cancer, life years gained) of HPV testing and what is the cost-effectiveness in Euro per life year gained (LYG) of including HPV testing in primary cervical cancer screening in the German health care context? How can the screening program be improved with respect to test combination, age at start and end of screening and screening interval and which recommendations should be made for the German health care context? METHODS: A previously published and validated decision-analytic model for the German health care context was extended and adapted to the natural history of HPV infection and cervical cancer in order to evaluate different screening strategies that differ by screening interval, and tests, including cytology alone, HPV testing alone or in combination with cytology, and HPV testing with cytology triage for HPV-positive women. German clinical, epidemiological and economic data were used. In the absence of individual data, screening adherence was modelled independently from screening history. Test accuracy data were retrieved from international meta-analyses. Predicted outcomes included reduction in lifetime-risk for cervical cancer cases and deaths, life expectancy, lifetime costs, and discounted incremental cost-effectiveness ratios (ICER). The perspective of the third party payer and 3% annual discount rate were adopted. Extensive sensitivity analyses were performed in order to evaluate the robustness of results and identify areas of future research. RESULTS: In the base case analysis screening resulted in a 53% to 97% risk reduction for cervical cancer with a discounted ICER between 2,600 Euro/LYG (cytology alone every five years) and 155,500 Euro/LYG (Annual cytology age 20 to 29 years, and annual HPV age 30 years and older). Annual cytology, the current recommended screening strategy in Germany, was dominated. In sensitivity analyses variation in the relative increase in the sensitivity of HPV testing as compared to cytology, HPV test costs, screening adherence, HPV incidence, and annual discount rate influenced the ICER results. Variation in the screening start age also influenced the ICER. All cytology strategies were dominated by HPV screening strategies, when relative sensitivity increase by HPV testing compared to cytology was higher (scenario analysis with data for test accuracy from German studies). HPV testing every one, two or three years was more effective than annual cytology. With increased screening adherence a longer screening interval and with low screening adherence a shorter interval would be more cost-effective. With a reduction in HPV incidence of more than 70% triennial HPV screening in women aged 30 years and older (and biennial Pap screening in women aged 20 to 29 years) is cost-effective. The discounted ICER increases with increasing annual discount rate. Increasing screening start age to 25 years had no relevant loss in effectiveness but resulted in lower costs. An optimal strategy may be biennial HPV testing age 30 years and older with biennial cytology at age 25 to 29 years (ICER of 23,400 Euro/LYG). CONCLUSIONS: Based on these results, HPV-based cervical cancer screening is more effective than cytology and could be cost-effective if performed at intervals of two years or greater. Increasing the age at screening start to 25 years causes no relevant loss in effectiveness but saves resources. In the German context an optimal screening strategy could be biennial HPV testing at age 30 years and older with biennial cytology at the age of 25 to 29 years. An extension to a three-yearly screening interval requires substantially improved screening adherence or a higher relative increase in the sensitivity of HPV testing as compared to cytology. The implementation of an organised screening program for quality-controlled introduction of HPV-screening and -vaccination with continued systematic outcome evaluation is recommended.
