Background: Heart failure (HF) is a clinical syndrome with a global burden. Signs and symptoms of HF are nonspecific and often shared with other conditions. The N-terminal prohormone of brain natriuretic peptide (NT-proBNP) serves as a useful biomarker for the diagnosis of HF not only in patients with acute symptoms but also in outpatients with an ambiguous clinical presentation.

Background: Treatment-resistant depression (TRD) in major depressive disorder (MDD) is most commonly defined as the failure to respond to at least two antidepressant (AD) treatments of adequate duration and adherence. While the health care utilization (RU) and costs of patients with MDD are well documented, little is known about patients with TRD. Therefore, the aim of this study was to determine the direct medical RU of complex therapy pathways and to analyze the total cost-of-illness and the burden-of-disease in Austria.

Objectives: Landiolol is an ultrashort-acting beta-blocker with high beta-1 receptor affinity and less blood pressure-lowering properties than other beta-blockers available for intravenous use in Germany. The present analysis aimed to determine whether perioperative treatment with landiolol in cardiac surgical patients is cost-effective under the conditions of the German Diagnosis-Related Groups health cost reimbursement system.

Design: On the basis of clinical outcome data from a meta-analysis that included 622 patients from 7 randomized controlled trials, a decision-model was developed to determine the cost-effectiveness of landiolol versus standard-of-care (SoC).

Recent Results Cancer Res

May 2019

The overall aim of this book is to set out the main changes needed in the field of economic and regulatory conditions as a consequence of these rapid developments in oncology. The traditional approaches of health economics, like health economic evaluation, health technology assessment (HTA), modeling methods, assessing value, pricing techniques, are bound to be altered in the contributions to this book. It is understandable that with the life-threatening diagnosis of cancer the new treatment options need to be accompanied by the best available health economic tools.

Background: Osteoporosis poses an immense burden to the society in terms of morbidity, mortality and financial cost. To reduce this burden, it is essential to accurately assess the individual patient's fracture risk and, where indicated, to initiate appropriate treatment that reduces fracture probability. Current screening and monitoring approaches include utilization of FRAX®, a web-based country-specific fracture risk assessment tool, and bone mineral density measurement by Dual Energy X-ray Absorptiometry (DXA).

Background: Primary infection of Toxoplasma gondii during pregnancy can be transmitted to the unborn child and may have serious consequences, including retinochoroiditis, hydrocephaly, cerebral calcifications, encephalitis, splenomegaly, hearing loss, blindness, and death. Austria, a country with moderate seroprevalence, instituted mandatory prenatal screening for toxoplasma infection to minimize the effects of congenital transmission. This work compares the societal costs of congenital toxoplasmosis under the Austrian national prenatal screening program with the societal costs that would have occurred in a No-Screening scenario.

Background: The evaluative health economics is a recent field of research in health economics. Cost-effectiveness decisions play an increasing role, particularly for policy-makers to find systematic decisions under uncertainty. The task is all the more important as the use of innovative health technologies for diagnosis, prevention and treatment is rapidly expanding and thus leads to financial restrictions in health care.

It is a well acknowledged fact that steep increases in health expenditures are mainly due to improvements in health technologies as well as the ageing of population combined with mounting societal preferences towards health. This "natural" tendency increasingly faces constraints of public budgets. Therefore, both efficiency and effectiveness considerations have to be put in place in order to allocate financial resources in such a way as to foster optimal results.
