2.3 Practices We intend to recruit 92 general practices and 12 paediatric practices. In every group practice, at least 2 practitioners will be recruiting. The recruited practices will be situated throughout Flanders, in urban and rural areas. Physicians will be excluded if the assumption of consecutive inclusion was violated (inclusion of less than two children in 1 month time). Physicians will be asked to complete a survey on communication skills to stratify the intervention groups, according to communicator style. After formal approval, physicians will be asked to provide us with their latest report on antibiotic prescribing profile, as provided by the Belgian National Health and Disability Insurance (RIZIV).
