Knowledge and attitudes regarding influenza vaccination among nurses: A research review

Introduction: Influenza vaccination rates among nurses remain suboptimal despite health authority recommendations in many countries and several vaccination campaign programmes to encourage nurses to be vaccinated in many institutions. We reviewed published studies investigating nurses' knowledge and attitudes towards influenza vaccination to establish what is known about the determinants of nurses' influenza vaccination practices. Methods: Relevant articles published up to July 2010 were identified through multiple databases (CINAHL, MEDLINE, PubMed, EMBASE, BNI, HMIC, PsycINFO, CMAC, and CNJ) using predetermined search strategies. Review of the titles and abstracts revealed 182 of 254 references were not relevant. Of 45 full papers reviewed, 32 did not report nurse data separately and one was a duplicate report of a study. Results: We included 12 research studies which had investigated the relationship between knowledge and attitudes towards influenza vaccination and nurses' vaccination practices published between 2003 and 2010. All the studies were descriptive and relied upon self-report data. The findings of this review indicate a relationship between knowledge, attitudes and vaccination practices of nurses. There were three main findings: first, there was a strong association between nurses' knowledge of influenza and vaccination and their vaccination status; second, the surveys showed a positive relationship between perceptions of influenza as a serious illness and vaccination as effective and safe and a positive vaccination status; and third, there was a relationship between nurses' vaccination status and their reported promotion of vaccination to their patients. Conclusion: This review indicates that higher knowledge and positive attitudes towards influenza vaccination have a significantly positive association with vaccination coverage among nurses. Further studies are needed to identify influences on nurses' attitudes and practices regarding influenza vaccination and the personal, organizational, and situational factors that influence the uptake of influenza vaccine by nurses.
