RESUMO
SUMMARY: Introduction. Seasonal influenza epidemics represent a cost that affects companies in terms of sick leave and lost productivity, therefore vaccination can improve occupational health. The vaccination of Healthcare Workers (HCW) has a dual function because in addition to protecting the workers, it also protects the most fragile patients. The students of medical and nursing degree courses, as well as other health professions, attend the workplace daily and are similar to workers in Legislative Decree 81/08. The purpose of this research is to assess the prevalence of students who are in favor of the introduction of a mandatory vaccination for healthcare workers, and to investigate what factors predispose them to be favorable. Methods. We performed a multi-center cross-sectional study using a validated questionnaire in a sample of students from different university courses from October 10th, 2017 to September 30th, 2018. For qualitative variables, absolute and relative frequencies, and for categorical variables Pearson's Chi-square test (χ2) were calculated. A multivariable logistic regression model was used. Results. A total of 3131 questionnaires were completed by 2132 women and 999 men. The prevalence of students who are favorable to the introduction of a mandatory flu vaccination is 87.3% and that this data is linked to the female gender (aOR 1.52 CI 95% 1.12-2.06), being a medical student compared to nursing (aOR 2.14 CI 95% 1.45-3.17), coming from central Italy (aOR 3.08 CI 95% 2.11-4.51) and northern Italy (aOR 3.09 CI 95% 2.12-4.49) compared to Southern Italy and the Islands, wanting to get vaccinated for the next season (aOR 6.37 CI 95% 3.73-10.88), declaring to have a good/excellent level of knowledge on vaccine-preventable diseases (aOR 1.44 CI 95% 1.04-1.99), planning a recommendation based on ministerial indications (aOR 2.12 CI 95% 1.28-2.30) and having received requests for clarification on vaccinations (aOR 2.02 CI 95% 1.44-2.85). Discussion. The sample of university students showed to be largely in agreement with the introduction of mandatory vaccination for HCW, which is important for the prevention of influenza virus in the workplace. To increase adherence of healthcare workers to vaccination campaigns against seasonal influenza in the workplace, it is necessary that operative strategies are implemented with educational messages.
