During the pre-intervention phase, various stakeholders, including GPs, pharmacists and parents will be interviewed in order to get a better contextual understanding of antibiotic use in Malta. A 1-year baseline surveillance system will also be set up to collect actual diagnosis-specific antibiotic prescribing by GP. This data will, at a later stage, be used to measure the change in antibiotic prescribing behavior post-intervention stage. GPs stage of behavior change and intention to prescribe antibiotics will also be measure pre-intervention using questionnaires based on the theory of planned behavior and the transtheoretical model.
