This study investigated the factors influencing influenza vaccination rates among health care personnel (HCP) and explored HCP's attitudes toward a policy of mandatory vaccination.Methods:
In September 2012, a 33-item Web-based questionnaire was administered to 3,054 HCP employed at a tertiary care hospital in metropolitan Detroit.Results:
There was a significant increase in the rate of influenza vaccination, from 80% in the 2010–2011 influenza season (before the mandated influenza vaccine) to 93% in 2011–2012 (after the mandate) (P < .0001). Logistic regression showed that HCP with a history of previous influenza vaccination were 7 times more likely than their peers without this history to receive the vaccine in 2011–2012. A pro-mandate attitude toward influenza vaccination was a significant predictor of receiving the vaccine after adjusting for demographics, history of previous vaccination, awareness of the hospital's mandatory vaccination policy, and patient contact while providing care (P = .01).Conclusions:
The increased rate of influenza vaccination among HCP was driven by both an awareness of the mandatory policy and a pro-mandate attitude toward vaccination. The findings of this study call for better education of HCP on the influenza vaccine along with enforcement of a mandatory vaccination policy.
