Vulnerable groups—such as pregnant women, children, older adults or individuals with chronic conditions—are often excluded or underrepresented in clinical trials. Therefore, some questions about drug safety in these groups are initially left unresolved. Resulting uncertainties may lead to in inadequate drug therapy for these individuals. On the other hand, there is a risk of prescribing drugs associated with known or as yet unknown side effects in these individuals.
To expand the knowledge base in this important area, the unit addresses research questions regarding the drug utilization and safety in vulnerable groups using the Pharmacoepidemiological Research Database (GePaRD). A particular focus of the unit is on drug exposure during pregnancy. Recently, we have completed the methodological work to use GePaRD for this research. This includes the development of algorithms to identify and classify pregnancy endpoints, accurately estimate the onset of pregnancy, and link mothers to their children.
Moreover, we investigate chronic use of drugs in children as well as in vulnerable adult populations such as persons with mental disorders.
"Current projects" provides examples of some of the projects carried out by the unit.
