Correlates of change in health care worker seasonal influenza vaccination rates among dialysis facilities

We conducted a campaign to increase seasonal influenza vaccination of dialysis health care workers (HCWs) in the District of Columbia, Maryland, Virginia, and West Virginia. Between the 2010-2011 and 2011-2012 influenza seasons we examined the correlates of change. HCW vaccination rates improved significantly (P < .01) from a mean +/- standard deviation of 64.5 +/- 27.4 to 72.7 +/- 23.1. Evidence-based practices were in wide use and although we did not find an association between these and improvement, we did find that lower-performing facilities tended to improve more (P < .01) and there was a positive relationship between patient influenza vaccination rates and improvement in HCW rates (P < .01), with the mean +/- standard deviation patient rate of 88.3 +/- 7.9 exceeding the HCW rate during the 2011-2012 season (P < .01).
