  • Background: Increasing influenza vaccination rates among healthcare personnel (HCP) is a priority. Historically, influenza vaccination rates among HCP have been <50% but increased to about 62% during the 2009-10 pandemic H1N1 season. We report HCP vaccination rates and attitudes towards mandated vaccination in two healthcare organizations, Scott & White Healthcare (SWH) in Texas and Kaiser Permanente Northwest (KPNW) in Oregon, which both have voluntary employee vaccination programs.

    Methods: HCP aged 18-65 years with direct patient contact were enrolled in a prospective cohort study from September-December 2010. Internet surveys were administered at enrollment and after influenza season. Influenza vaccination was confirmed using personal medical records and employee health records. The post-influenza season survey asked participants about their attitudes towards mandated influenza vaccination and 13 other possible interventions to increase vaccine coverage.

    Results: Ninety-three percent (1701/1834) of enrolled participants completed both surveys and are included in this analysis. Influenza vaccine coverage was 74.5% (74% at SWH, 76% at KPNW). Older age, being married, and prior influenza vaccination were associated with higher vaccination rates. Most vaccinated HCP (98%) were vaccinated in conjunction with the employee vaccine campaigns between October and November, 2010. Forty-six percent (782/1701) of participants agreed with the statement that influenza vaccination should be required for HCP; vaccinated participants, SWH employees, and physicians were more likely to agree with this statement. Among 394 unvaccinated HCP asked if they would have received influenza vaccine if it was mandatory, 48% responded yes, 30% said no, and 22% were unsure. A mandate was ranked as the most influential intervention among unvaccinated HCP who reported low intention to be vaccinated in the upcoming season.

    Conclusion: Influenza vaccine coverage within these two healthcare organizations is higher than national averages, but falls short of universal coverage. Nearly all of the vaccinated HCP received vaccine as part of the employee vaccination campaigns. Mandating vaccination may lead to improved coverage rates, especially among unvaccinated HCP with low intention to be vaccinated.
