Aim: To provide an overview of thresholds for incremental cost-effectiveness ratios (ICERs) representing willingness-to-pay (WTP) across multiple countries and insights into exemptions pertaining to the ICER (e.g., cancer).

Background: Several tyrosine kinase inhibitors (TKIs) are approved for the treatment of chronic myeloid leukemia (CML). Decision-analytic modeling can help to extrapolate data from short-term clinical trials and also consider quality of life when evaluating different treatment strategies.

Objective: Our goal was to describe and analyze the structural and methodological approaches of published decision-analytic models for various treatment strategies in CML and to derive recommendations for the development of future CML models.

Objectives: The provision of self-pay medical services is common across health care systems, but understudied. According to the German Medical Association, such services should be medically necessary, recommended or at least justifiable, and requested by the patient. We investigated the empirical evidence regarding frequency and practice of self-pay services as well as related ethical, social, and legal issues (ELSI).

Background: The German statutory health insurance (GKV) reimburses all health care services that are deemed sufficient, appropriate, and efficient. According to the German Medical Association (BÄK), individual health services (IGeL) are services that are not under liability of the GKV, medically necessary or recommendable or at least justifiable. They have to be explicitly requested by the patient and have to be paid out of pocket.

Objectives: The aim of this study was to compare the predictive value, clinical effectiveness, and cost-effectiveness of high-sensitivity C-reactive protein (hs-CRP)-screening in addition to traditional risk factor screening in apparently healthy persons as a means of preventing coronary artery disease.

Methods And Results: The systematic review was performed according to internationally recognized methods. Seven studies on risk prediction, one clinical decision-analytic modeling study, and three decision-analytic cost-effectiveness studies were included.

Objective: To compare the predictive value and the clinical effectiveness of additional high sensitivity C-reactive protein (hs-CRP) screening as opposed to traditional risk factor screening alone as a strategy of primary prevention of coronary artery disease (CAD).

Methods: Following a comprehensive search of 26 electronic databases by DAHTA DIMDI, a systematic review was performed in accordance with international standards of evidence based medicine. Eight publications on risk prediction and one study addressing clinical decision-analytic modelling were included in the assessment.

Objectives: The objectives of this study were (i) to develop a systematic framework for describing and comparing different features of health technology assessment (HTA) agencies, (ii) to identify and describe similarities and differences between the agencies, and (iii) to draw conclusions both for producers and users of HTA in research, policy, and practice.

Methods: We performed a systematic literature search, added information from HTA agencies, and developed a conceptual framework comprising eight main domains: organization, scope, processes, methods, dissemination, decision, implementation, and impact. We grouped relevant items of these domains in an evidence table and chose five HTA agencies to test our framework: DAHTA@DIMDI, HAS, IQWiG, NICE, and SBU.

Background: Hepatitis C virus (HCV) infection is an emerging problem in public health. In most countries, the majority of HCV infected people are yet undiagnosed. Early detection and treatment may result in better health outcomes and save costs by preventing future advanced liver disease.

Background: Hepatitis C virus (HCV) is a leading cause of chronic liver disease, end-stage cirrhosis, and liver cancer, but little is known about the burden of disease caused by the virus. We summarised burden of disease data presently available for Europe, compared the data to current expert estimates, and identified areas in which better data are needed.

Methods: Literature and international health databases were systematically searched for HCV-specific burden of disease data, including incidence, prevalence, mortality, disability-adjusted life-years (DALYs), and liver transplantation.

Background: In a substantial portion of patients (= 25%) with coronary heart disease (CHD), a myocardial infarction or sudden cardiac death without prior symptoms is the first manifestation of disease. The use of new risk predictors for CHD such as the high-sensitivity C-reactive Protein (hs-CRP) in addition to established risk factors could improve prediction of CHD. As a consequence of the altered risk assessment, modified preventive actions could reduce the number of cardiac death and non-fatal myocardial infarction.

Objectives: Progression-free survival (PFS) has not been validated as a surrogate endpoint for overall survival (OS) for anthracycline (A) and taxane-based (T) chemotherapy in advanced breast cancer (ABC). Using trial-level, meta-analytic approaches, we evaluated PFS as a surrogate endpoint.

Methods: A literature review identified randomized, controlled A and T trials for ABC.

Background/aims: Peginterferon plus ribavirin is the state-of-the-art antiviral therapy for prevention of serious complications of hepatitis C. Our aim was to compare market uptake of and access to these drugs across Europe.

Methods: We collected launch and sales data for peginterferons for 21 countries in the WHO European region and compared country-specific sales rates.
