Knowledge, Attitude and Awareness Toward Influenza Vaccination Among Patients Admitted to the Infectious Diseases Outpatient Clinic of a Research Hospital

Introduction: Worldwide influenza vaccination rates remain low despite guideline recommendations to support vaccinations. It is important to identify attitudes, barriers and motivating factors influencing patients’ vaccination behaviours. We aimed to evaluate the knowledge, attitudes and factors influencing the vaccination behaviours against influenza and sources of information used by patients about influenza vaccine. Materials and Methods: This was a cross-sectional, self administered questionnaire-based study of 229 patients who visited infectious diseases and clinical microbiology outpatient clinic between December 2018 and February 2019. The questionnaire consisted of 39 items in 5 sections: Demographic data (8), questions about influenza vaccine (9), vaccination history (2), factors influencing vaccination behaviours (18) and sources of information used by patients about influenza vaccination (2). Results: Vaccinated group had a higher education level compared to the unvaccinated group, and the difference was statistically significant (p= 0.007). Vaccination against any diseases in adulthood was also statistically higher in the influenza-vaccinated group (p= 0.000). Other features were similar in both groups. The percentage of correct answers to proposals were similar and high between the two groups. Correct answers given to “People with chronic illness should have a flu vaccine” was statistically higher in the vaccinated group (80.5% vs. 61.8%, p= 0.004). Regular annual vaccination rate was only 10.3% in the vaccinated group. The most common motivating factor in vaccination was doctor’s advice (54.5%). The most common barrier against influenza vaccination was the idea that they did not need vaccination (51.3%). The information source affecting the patients mostly was the doctors in both vaccinated and unvaccinated groups. Conclusion: In order to increase the knowledge level and vaccination rates, doctors should be informed rigorously about advising influenza vaccine to patients, especially high risk groups. Education and advice from healthcare professionals about vaccine is crucial for increasing vaccination rate.
