“…In agreement with other studies that have shown the effectiveness of influenza immunization campaigns to promote an increase in vaccination uptake, we documented a significant increase in the number of vaccinated HCPs, mainly physicians, during P2 after the educational programme was implemented [7][8][9][10].…”

“…A poorly protective vaccine due to major antigenic changes could have been a concern, as recently shown by the low 2014/2015 vaccine effectiveness (VE) against influenza A(H3N2) (18-23% VE) and B (45% VE) viruses. In addition, studies conducted in different parts of the world have shown that the reasons for HCP declining influenza immunization are mostly related to the perception that the illness is mild or not severe enough, and also to concerns regarding adverse events, needles, and the lack of contact with high-risk patients, which was also documented in our study [1,7,8,10]. Overall it appears that the main reasons for opting out of influenza vaccination are similar regardless of the study location.…”

Impact of an influenza vaccine educational programme on healthcare personnel

Influenza vaccination has been shown to be the most effective preventive strategy to reduce influenza-related morbidity and mortality in high-risk groups. Despite healthcare personnel (HCP) being considered part of such high-risk groups, their vaccination coverage is low in Europe. In January 2012, we distributed an 18-question survey regarding influenza vaccination to HCP at Gregorio Marañon Paediatric Hospital, in Madrid, Spain. After we documented that only ~30% of HCP were vaccinated an educational programme was implemented in October 2012 before the next influenza season. In January 2013, the same survey delivered again to all HCP documented a significant increase in vaccination rates (from 30% to 40%, P = 0·007) mainly among physicians and for patients' protection. In summary we found that a simple and inexpensive educational programme significantly improved the uptake of influenza vaccination in HCP in our centre. Nevertheless, vaccination rates remained low, and broader and updated campaigns are needed to overcome perception barriers.

“…However providers themselves may be hesitant to vaccinate themselves, may underestimate the influence of their recommendation, and may consider themselves not to be effective in managing a vaccine-related discussion [33]. Hesitancy may not be simply overcome by providing more information or even enhancing risk perception [34]. A recent trial of a physician-targeted communication intervention showed no effective increase in physician self-efficacy or decrease in parental hesitancy [35].…”

“…After three influenza vaccination campaigns for HCWs at the Hospital Clínic of Barcelona (HCB) that fostered participation [30, 31], the present study was conducted to describe to whom HCWs speak or interact with around a campaign. In particular, we assessed whether HCWs were more likely to discuss vaccination and the campaign with peers with the same vaccination behavior.…”

BackgroundInfluenza vaccination coverage remains low among health care workers (HCWs) in many health facilities. This study describes the social network defined by HCWs’ conversations around an influenza vaccination campaign in order to describe the role played by vaccination behavior and other HCW characteristics in the configuration of the links among subjects.MethodsThis study used cross-sectional data from 235 HCWs interviewed after the 2010/2011 influenza vaccination campaign at the Hospital Clinic of Barcelona (HCB), Spain. The study asked: “Who did you talk to or share some activity with respect to the seasonal vaccination campaign?” Variables studied included sociodemographic characteristics and reported conversations among HCWs during the influenza campaign. Exponential random graph models (ERGM) were used to assess the role of shared characteristics (homophily) and individual characteristics in the social network around the influenza vaccination campaign.ResultsLinks were more likely between HCWs who shared the same professional category (OR 3.13, 95% CI = 2.61–3.75), sex (OR 1.34, 95% CI = 1.09–1.62), age (OR 0.7, 95% CI = 0.63–0.78 per decade of difference), and department (OR 11.35, 95% CI = 8.17–15.64), but not between HCWs who shared the same vaccination behavior (OR 1.02, 95% CI = 0.86–1.22). Older (OR 1.26, 95% CI = 1.14–1.39 per extra decade of HCW) and vaccinated (OR 1.32, 95% CI = 1.09–1.62) HCWs were more likely to be named.ConclusionsThis study finds that there is no homophily by vaccination status in whom HCWs speak to or interact with about a workplace vaccination promotion campaign. This result highlights the relevance of social network analysis in the planning of health promotion interventions.Electronic supplementary materialThe online version of this article (doi:10.1186/s13012-016-0522-3) contains supplementary material, which is available to authorized users.
