A novel approach to improve influenza vaccination rates among health care professionals: a prospective randomized controlled trial.
ABSTRACT Although influenza is the leading infections cause of death in the United States, only 40% of health care workers (HCW) comply with Centers for Disease Control and Prevention recommendation for routine influenza vaccination.
This study investigated a novel approach for improving influenza vaccination rates among HCW. Eight hundred employees we selected, 200 each from the following 4 categories: professional staff, resident physicians, registered nurses, and licensed practical nurses. Subjects were randomly assigned to receive (1) no intervention, (2) a letter explaining the importance of influenza vaccine for HCW, (3) a ticket activated with influenza vaccine administration for a raffle of a free Caribbean vacation for 2, or (4) both the educational letter and the raffle ticket. We compared the proportion of employees receiving vaccination and participating in the raffle across groups.
The influenza vaccination rate for all study subjects was 41%. The number of subjects receiving vaccine did not differ by occupation (P = .87) or intervention group (P = .66).
This study provides no evidence to support the use of mailed educational letters or a single large raffle prize incentive as a means to boost hospital employee influenza vaccination rates.

ABSTRACT: Health Authorities recommend influenza vaccination of healthcare personnel (HCP) to decrease the transmission of influenza to vulnerable patients. Recent studies have almost exclusively used quantitative questionnaires in order to identify determinants of vaccination behaviour. Interviews enable HCP to express freely why they think they are (not) willing to get vaccinated against influenza. By means of semi-structured one-on-one interviews with 123 Belgian, Dutch and German HCP, reasons for and against vaccination, experiences with influenza vaccination, intention to get vaccinated and possible barriers, as well as willingness to advice influenza vaccination to patients were investigated. Data were processed with QSR NVivo 8.0 and analysed using a combination of a deductive and a general inductive approach. Across countries, self-protection, patient protection, and protection of family members were reported as most important reasons to get vaccinated against influenza. Reasons to not get vaccinated against influenza were fear of side effects caused by the vaccine, a low risk-perception, the disbelief in the effectiveness of influenza vaccination, organizational barriers, misconceptions, and undefined negative emotions. The social cognitive variables underlying the decision of HCP to get vaccinated against influenza (or not) seem to be similar in Belgium, Germany, and the Netherlands, even though some differences surfaced. A quantitative investigation of those social cognitive variables is needed in order to determine the importance of the social cognitive variables in explaining the intention to get vaccinated and the importance of the similarities and differences between countries that have been found in this study.BMC Public Health 04/2014; 14(1):407. · 2.32 Impact Factor

ABSTRACT: Influenza vaccination uptake of healthcare personnel is low in Europe.•Positive attitudes predict a high intention to receive influenza vaccination.•Attitude mediates the effect of moral norms on intention to vaccinate.•Intention to get vaccinated against influenza is a good predictor of immunization.•Indecisive healthcare personnel are a promising group for vaccination campaigns.Vaccine 10/2014; · 3.49 Impact Factor
