Health Economics

Background

Health economics research enables policymakers to make evidence-based decisions on how to allocate limited health care resources efficiently. Efficiency here is not necessarily about cutting costs, but rather about determining how to derive the maximum total benefit from limited available resources.

In the same way that evidence-based medicine makes use of formal evidence on effectiveness of interventions, health economics answer the need to formally assess the implications of choices about the deployment of resources. Since resource use is best expressed in costs, a number of economic evaluation techniques have been developed to compare costs and clinical outcomes of competing treatment alternatives in order to identify the most efficient treatment.

Service

The Health Economics Working Group at the Medical Center - University of Freiburg was established as a collaboration between the Center for Medical Biometry and Medical Informatics, the Clinical Trials Unit, and the University Heart Centre. We have a strong methodological background in regression modelling and econometrics. In addition to our own research projects, we provide methodological support for economic evaluations across all types of clinical research.
