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.

    • "Unfortunately, with vaccination coverage rates ranging from 6.4–26.3% among European HCP [7] [8], the recommendations have not had their intended impact, and recent intervention programs developed to increase vaccination rates show at most small effects [9] [10] [11] [12] [13]. "

    ABSTRACT: Health Authorities recommend annual vaccination of healthcare personnel (HCP) against influenza to protect vulnerable patients. Nevertheless, vaccination rates have been low among European HCP. Here we report on a longitudinal survey study to identify social cognitive predictors of the motivation to obtain influenza vaccination, and to test whether intention is a good predictor of actual vaccination behaviour. Dutch HCP (N = 1370) were invited to participate in a survey (baseline). To link intention to behaviour, participants who completed the first survey (N = 556) were sent a second survey after vaccinations were offered (follow-up). Multinominal regression analysis showed that HCP with a positive attitude and a higher frequency of past vaccinations were more likely to have a high intention to get vaccinated. A negative attitude, high feelings of autonomy in the decision whether to get vaccinated, a preference of inaction over vaccination, a lesser sense of personal responsibility, and high self-protection motives increased the probability of no intention to get vaccinated. Social cognitive predictors were identified that explain the intention to get vaccinated against influenza of HCP, which in turn proved to be a good predictor of behaviour. Future interventions should focus on these variables to increase vaccination coverage rates.

    • "Influenza vaccination has been shown to be safe and effective [7,8] and can be given relatively effortless to a large group of people. Although benefits are clearly demonstrated [6,7] and hospitals simplified the process of HCP getting vaccinated by offering free vaccine on work-site and by giving necessary information [9-11], the actual vaccination numbers are generally low and stay far below Health Authority recommendations [2,12,13]. A study comparing 11 European countries found vaccination coverage rates of 6.4 to 26.3% among HCP [14]. "

    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.

    ABSTRACT: Mandatory influenza vaccination of health-care workers (HCWs) has been widely studied and debated. State legislators are beginning to use their authority to enact laws requiring HCW vaccination as an infection-control measure. This installment of Law and the Public's Health reviews the role of state law in promoting influenza vaccine uptake among the health-care workforce.
