Description of the complex intervention
INFLUENZA
Against the aforementioned background, a bundle of measures to increase vaccination uptake will be implemented in GP practices. The aim of the intervention is to raise further awareness among GPs and medical assistants about the importance of vaccinations for patients aged 60 and older, to provide them with training in vaccination expertise and communication psychology, to introduce suitable tools for vaccination recall into their practice routines, and to update them on where to find target group appropriate information for patients.As the first component of the intervention, GPs and their medical assistants complete an accredited online training. The main goal of the online training is to increase medical knowledge about vaccinations and vaccination counselling skills. This is intended to promote vaccine-related communication between GPs and patients, improve patient vaccine literacy, and thereby increase vaccination uptake. Furthermore, participating GP practices will receive a first material package containing appointment reminder cards, a poster on vaccination, checklists on the vaccination procedure in outpatient care and nursing homes, an infosheet with the most important contents from the online training, an immunisation schedule with an overview of recommended vaccinations, and templates of consent forms for vaccination reminders for the following influenza vaccination season.In the second year of the intervention, the GP practices will again receive a second material package before the start of the influenza vaccination period. This contains, among other things, the materials needed for the upcoming vaccination recall (customisable postcards and matching envelopes). The intervention is planned to be implemented in the GP practices from 01.07.2022 to 31.03.2024. Figure
