Background: In the United States, vaccination of Health Care Workers (HCW) for seasonal influenza has been shown to reduce the risk for influenza-related illness, nosocomial infections and worker absenteeism. Despite the benefits of HCW vaccination, rates for influenza vaccination for HCWs have remained unacceptably low. We assessed correlates of seasonal influenza vaccination among HCWs at a large academic medical center during the Fall 2010 to Spring 2011 influenza season.

Methods: During a university annual open enrollment benefits period (October 2010), all employees completed a web-based questionnaire prior to election of benefits. As part of this questionnaire, a 7-item survey instrument assessed the intent, receipt, location, and rationale for declining influenza vaccination. Data on specific occupation type, HCW status, campus location, and select sociodemographics were analyzed.

Results: Over 98% of all university employees (n=10,823) completed the benefits questionnaire including the seasonal influenza vaccination items. Among all HCWs (n=3,141), 48% reported receiving or intending to receive the seasonal influenza vaccine during the 2010-2011 season; however variation by specific HCWs was noted: physicians (69%), physician assistants/nurse practitioners (51%), nurses/licensed practical nurses (35%), allied health professionals (57%), and direct patient contact staff (34%). After adjustment for sociodemographic (i.e. age and gender) indicators, nurses, allied health professionals, direct patient contact staff and non-healthcare workers were significantly less likely to report receipt or intent in receiving seasonal flu vaccine for the 2010-2011 season as compared to physicians (Adjusted odds ratio, AOR = 0.58, 95% CI [043–0.79]); 0.59[0.43-0.81]; 0.67[0.47-0.96], and 0.57[0.46-0.71], respectively). Report of receiving the seasonal flu vaccine in the previous flu season was significantly associated (17.79[16.10-19.68]) with reporting receipt or intention to receive the flu vaccine in the 2010-2011 season.

Conclusion: There is significant variability in the vaccination rates among different groups of HCW. Development of targeted effective vaccination campaigns are needed to improve vaccination rates.
