Influenza vaccination and its influencing factors among clinical staff of the hospitals in 2016-2017 season, Xining, Qinghai province, China

Abstract

Objective: To investigate the influenza vaccination and its influencing factors among the clinical staff in Xining, Qinghai province, in the 2016-2017 influenza season, and to explore the promoting strategies to encourage the target population for influenza vaccination. Methods: Four sample hospitals were randomly selected from the total 11 tertiary hospitals in Xining city. Clinical staff that worked in the four hospitals and agreed to participate were recruited for investigation via a self-administered questionnaire. Results: During the 2016-2017 influenza season, the coverage rate of influenza vaccines among the clinical staff was 5.14% (95%CI: 4.80%-5.49%). Multivariate logistic regression showed that knowing the priority of vaccination, the frequency of vaccination, effect of vaccination, and possessing higher professional qualifications were major influencing factors for influenza vaccination. The intention on recommendation of seasonal influenza vaccine was higher in vaccinated group than that in the unvaccinated group (χ(2)=99.57, P<0.001). Conclusion: The lower coverage rate was primarily associated with the lack of knowledge about influenza vaccine among the clinical staff of the hospital. Tailored information should be provided to the clinical staff through effective methods to improve vaccination and the recommendation of influenza vaccine.
