Prescribing antibiotics in general practice: The use of microbiological testing and other factors influencing decision-making and prescribing behaviour

Research output: Contribution to conference without publisher/journalConference abstract for conferenceResearch


The majority of antibiotics are prescribed from general practice. The use of broad-spectrum antibiotics increases the risk of development of bacteria resistant to antibiotic treatment. In spite of guidelines aiming to minimize the use of broad-spectrum antibiotics we see an increase in the use of these agents. The overall aim of the project is to explore factors influencing the decision process and the prescribing behaviour of the GPs when prescribing antibiotics. We will study the impact of microbiological testing on the choice of antibiotic. Furthermore the project will explore how the GPs’ prescribing behaviour is influenced by selected factors.

The study consists of a register-based study and a questionnaire study. The register-based study is based on data from the Register of Medicinal Product Statistics (prescribed antibiotics), Statistics Denmark (socio-demographic data) and the Danish Microbiology Database (performed microbiological testing). We will assess and quantify the use of microbiological testing prior to antibiotic prescription. Furthermore we will investigate associations between GP characteristics, use of microbiological investigations and description patterns. A questionnaire comprising a discrete choice experiment will allow us to investigate the relative importance of selected factors (e.g. microbiological diagnostics, point-of-care tests, patients' expectations) in the management of infectious diseases.

This PhD project is scheduled to be carried out in 2016-2019. The hypotheses and anticipated perspectives will be discussed at the conference.

This project will contribute with solid knowledge on diagnostic approaches for management of infections in Danish general practice. The results will create a base for targeted interventions aiming to optimize diagnostic approaches to infectious diseases benefitting the individual patient and society as a whole.
