Abstract
In this tutorial, statistical methods for studying outpatient use of antibiotics in Europe are described, using data provided by IMS Health. The methods are applied to two related research questions, namely the assessment of changes in the relative volume of use of different antibiotic subclasses over time and changes in the absolute volume of antibiotic use.
