ObjectivesIn Slovenia, the role of family physicians in primary care and preventive procedures is very important. Influenza vaccination rates in Slovenia are low. The reasons for low vaccination rates in Slovenia were not clear. We suppose that patient’s beliefs and attitudes are important factors. We assessed patients’ opinions regarding the acceptance of flu vaccination by their family physicians and their beliefs and attitudes about flu and vaccination. The aim was to check out factors that influence the decision to take the vaccine in family physician offices.MethodsThis was a cross-sectional, multicenter, observational study in the Styria region in Slovenia. We included patients from seven family physicians during regular office visits. They filled in a questionnaire about their general demographic data and attitudes regarding influenza and vaccination. The main outcome was the decision to be vaccinated.ResultsThe logistic regression model identified five predictors for influenza vaccination, namely: heart disease, previous vaccination, an agreement with the beliefs ‘the vaccination is an efficient measure to prevent influenza’, ‘after the vaccination there are usually no important side effects’ and ‘the vaccination is also recommended for a healthy adult person’. The belief that vaccinations harm the immune system is negatively associated with vaccination.ConclusionsPatients’ beliefs are an important factor to decide for vaccination or not. Family physician teams should discuss with patients their beliefs and concerns about vaccination.
