    Better Knowledge and Regular Vaccination Practices Correlate Well with Higher Seasonal Influenza Vaccine Uptake in People at Risk: Promising Survey Results from A University Outpatient Clinic
    (2017) Guvenc, Isil Adadan; Parildar, Hulya; Sahin, Mustafa Kursat; Erbek, Selim Sermed; https://orcid.org/0000-0003-4825-3499; 28449918; S-2103-2016; B-7604-2019
    Background: The knowledge, beliefs, opinions, and attitudes of patients and their relatives regarding seasonal influenza vaccination were evaluated. Methods: This descriptive study was undertaken in the outpatient clinics of Baskent University Hospital. There were 566 responders who completed a self-administered questionnaire. Results: The mean age of participants was 48.35 years, and 16.8% were >= 65 years. Of the responders, 21.7% were vaccinated this year, whereas 57.8% did not desire to get it. Vaccination rates were significantly higher among responders >= 65 years of age (56.4%), those having at least 1 chronic illness (46.5%), and those who were vaccinated regularly every year (22.2%). Half of the responders did not know that the vaccine was reimbursed for people at risk. The most common reason for refusing the influenza vaccine was not getting the flu frequently (51.2%). Fear of side effects, concerns about vaccine's effectiveness, and belief that vaccine causes the flu were other common reasons for not being vaccinated. Of the responders, 77% believed that getting official information or a recommendation from a physician would influence their decision about seasonal influenza vaccination. Conclusions: People who are at risk or vaccinated regularly display a higher vaccine uptake and better knowledge of influenza and vaccination. The opinions and attitudes of this study population may assist in developing strategies for changing attitudes of the public toward influenza vaccination.

    Influence of Influenza Vaccination on Recurrent Hospitalization in Patients with Heart Failure
    (2017) Kaya, H.; Beton, O.; Acar, G.; Temizhan, A.; Cavusoglu, Y.; Guray, U.; Zoghi, M.; Ural, D.; Ekmekci, A.; Gungor, H.; Sari, I.; Oguz, D.; Yucel, H.; Zorlu, A.; Yilmaz, M. B.; 27460050
    The current study aimed to evaluate the influence of regular annual influenza vaccinations on cardiovascular (CV) death and heart failure-related hospitalizations (HFrH) in stable outpatients with heart failure with reduced ejection fraction. The Turkish research team-HF (TREAT-HF) is a network undertaking multicenter, observational cohort studies in HF. This study is a subgroup analysis of TREAT-HF outpatient cohorts who completed a questionnaire on influenza vaccination status and for whom follow-up data were available. A total of 656 patients with available follow-up data for CV death and HFrH including recurrent hospitalization were included in the study. Patients were classified into two groups: those who received regular influenza vaccination (40 %) and those who did not receive vaccination. During a mean follow-up of 15 +/- 6 months, 113 (18 %) patients had CV death and 471 (72 %) patients had at least one HFrH. The CV death rate was similar in both groups of patients (16 vs. 19 %, p = 0.37), whereas, HFrH and recurrent HFrH were significantly less frequently encountered in patients who received regular influenza vaccination than in those who did not receive vaccination (43 vs. 92 % and 16 vs. 66 %, p < 0.001, respectively). In a multivariate Cox proportional hazards model - in addition to a few clinical factors - vaccination status (HR = 0.30, 95 % CI = 0.17-0.51, p < 0.001) and graduation from university (HR = 0.35, 95 % CI = 0.17-0.72, p = 0.004) remained independently associated with the risk of recurrent HFrH. Regular influenza vaccination does not influence CV deaths; however, it decreases HFrH including recurrent episodes of HFrH in outpatients with heart failure with reduced ejection fraction.
