Effectiveness of an educational intervention on seasonal influenza vaccination campaign adherence among healthcare workers of the Palermo University Hospital, Italy.

INTRODUCTION: Healthcare workers are continuously exposed to the risk of being infected by influenza viruses during their work, thus representing a threat especially for fragile patients. Although the Italian Ministry of Health strongly recommends influenza vaccination for all HCWs, coverage levels in Italy are still far from the expected. Several studies report that one of the preferred strategies to improve vaccination coverage among Healthcare Workers is improving vaccination knowledge through specific multidisciplinary courses. To assess the effectiveness of an educational intervention on influenza vaccination coverage among Healthcare Workers a study was conducted at "Paolo Giaccone" University Hospital of Palermo, in the occasion of the 2016/2017 seasonal influenza vaccination campaign. MATERIAL AND METHODS: Educational interventions on influenza infection and vaccination were organized involving personnel of the hospital units in which patients were more fragile. The Healthcare Workers who volunteered attend the course were considered as the intervention group, while two controls for each case, composed by Healthcare Workers not attending it, were randomly selected from the same unit. For both groups, a questionnaire was used to investigate attitude and behaviors toward influenza vaccination, while vaccination coverage data were obtained throughout the Hospital informational data system. RESULTS: Overall, out of the 125 participants, 38 (30.4%) followed the course (intervention group) and 87 (69.6%), not attending the course, represented the control group; later, only 43 Healthcare Workers out of 125 (34.4%) underwent vaccination during the season considered. In particular, after the educational intervention, 42% of the attending Healthcare Workers got vaccinated, while vaccination prevalence in the control group was 31%. The Healthcare Workers who underwent vaccination reported, before the intervention, a higher risk perception for contracting (transmitting) influenza compared to those not vaccinated (p<0.05), while no significant difference in risk perception of transmitting influenza to their patients was reported between the two groups. DISCUSSION: Despite the training provided, and an improvement in vaccination adherence by the Healthcare Workers involved, coverage obtained was lower than recommended to reduce influenza spread in hospital contexts. In conclusion, our data suggest that specific training alone may play a role in the improvement of influenza vaccination adherence, but it should be integrated by a wider range of public health measures, including mandatory vaccination.

Factors associated with reporting adverse reactions after immunization, study in a sample of university students.

INTRODUCTION: On the day of a workshop (named "Vaccino Day") on vaccinations, organized for the students of the University of Palermo by the ERSU (Regional Office for the Right to University Study), the sample of students were given a questionnaire to fill out. The aim of the survey was to investigate the perception of vaccinations on a sample population made up of university students. STUDY DESIGN: A self-administered paper questionnaire was given to participants of the workshop. The questionnaire is divided into 3 parts: demographic, economic and habits informations have been asked in the first part; in the second part, they had to answer the question: "What term do you associate with vaccination?"; in the third part, they were posed the question: "Have you ever had any adverse reactions after being vaccinated?". Therefore, the percentage response frequencies and the statistically significant Odds-Ratio (aOR) are presented with a corresponding 95% confidence interval (CI). Statistical analysis was performed using the STATA® 14 software. METHODS: A total of 350 students were asked to participate and the response rate was 100%, the 61.43% of the interviewed population was made up of females. Taking into account the dependent variable: "at least a moderate-severe adverse reaction after a vaccination" the statistically significant independent variables associated are "Have fear of side effects" (aOR 7.06, 95% CI 1.73-28.57, p=0.006), "I associate the term "vaccination" to Needles/syringes" (aOR 3.82, 95% CI 1.08-13.48, p=0.037), "I associate the term "vaccination" to Protection" (aOR 3.50, 95% CI 1.02-11.98, p=0.046). DISCUSSION AND CONCLUSIONS: Vaccination is still influenced by emotional factors and lack of campaigns providing adequate information, therefore negative judgement tend to outweigh the real risks and benefits. Considering that the sample was composed of university students, being highly educated and capable of becoming opinion leaders in the future, there is a need to create a more efficient communication protocol that make the student, and then the citizen, better aware of the actual risks associated with vaccinations and their real benefits.
